Similarities between these two shounen serialisations include: characters with unique abilitites which they oftentimes use for combat; the emphasis placed on comradery; and a vast world for exploration. Moreover, both share very similar art and narrative styles.
They are drawn the same way. There is a strong emphasis on friendship,the characters are enjoyable, and there is alot of humor. The fights are great and they do not drag on. all and all an enjoyable series that you should check out if you like shouen.
But it's true, although the story line is a bit different, almost every character in both series share a resemblence with each other, not only that, there are fights which can me compared with each other, and several scenes almost look the same. The art style does look a lot the same too, after Mashima's earlier work, Rave Master, his art style got more devoted (and improved) towards Oda's style/work.
For those of you who are fans of One Piece, I highly recommend reading Fairy Tail. The author of Fairy Tail used to be an assitant to Oda(Author of One Piece) thus they share many characteristics, especially artwork. Both series have great fights with equally great character designs. All the great fundamentals of an epic Manga like One Piece, with a different plot and set-up, are all the ingredients you need for a good read!
It's simmilar humor, so if you think One Piece is funny you will think that Fairy Tail is too. The main characters in these two mangas are alot alike, they are both rash, violent, loud and not so smart. This makes the manga very funny.
Like in One piece, Natsu is a very powerful guy and very funny.
Either in One Piece and Fairy Tail, there are some guys (and Luffy and Natsu too) who have powers very cool.
If you like One piece, you surely love Fairy Tail.
It's got an awesome main character somewhat similar to luffy. It has a unique story arcs that will surely entertain you. It's very entertaining and will most likely keep you guessing. It can be random and odd at times (which is what keeps you guessing), but it has decent and relatable humor. The characters are all just as unique and interesting.It's a very creative and original anime that won't fail your expectations. It can be emotional and intense but that's what makes it so interesting.
This is one of the top manga out there for a good reason. don't be hesitant to go and check it out, you may even like it a lot more than you thought at first. read more
Both have really similar art styles for one. The initial main characters are really similar in personality and appearance. They also both have a lot of adventure and are about standing up for ones friends. The biggest difference is that one is about mages and one is about pirates.
Friendship and epic battles between different groups of people. That's wath these manga are al about. The main characters both belong to one of the strongest groups in the world. They embark on an epic journey with exciting battles and powers that will leave you shocked. They also contain a lot of (similar) humour.
Both series involve the bonds of friendship, with One Piece having the relationships between the Strawhat crew while Fairy Tail involving the relationships between the Fairy Tail guild.
Both have a vast amount of characters that have interesting and unique backgrounds and different environments for the characters to explore.
Both main characters (Luffy and Natsu) are extremely similar as they have the ambition to protect their friends.
Both series have a large amount of action and use of supernatural powers.
When you get into depth of both series, they're very similar. Both have setting with fantastic people, animals and landscapes, both have legendary figures, evil organizations and both the protangonists are after something very rare and valuable.
A vast world that seem to have no end to it, incredibly cool and original powers and last but not least very stunning and exciting battles. Both of the main characters in these manga belong to a select group of people with a very special power. They both embark on an epic journey that will take them to every corner of the world they live in. If you like action packed shonen stories, then these manga are perfect for you!
both have very stupid, funny and strong main characters, both have a very strong story line that had good twists along the way and both get very good groups of friends and both manga are very action packed.
I'll start by saying that fans of these series go back and forth arguing which is better. They are both different in that Naruto is about Ninjas and One Piece is about Pirates. They both have a main character that is kind of an idiot, gets stronger as the story goes on, defeats many opponents he has no business even fighting and so much more. Both are heavily themed about comradery and how important it is to have "nakama" you care for and take care of.
Naruto was my gateway anime/manga, and in my search for something to fill my time between my obsession of Naruto I eventually came upon One Piece. Though it starts out as a fun little adventure story (not quite as strong in the beginning as Naruto), it becomes an amazingly epic adventure that surpasses Naruto in many many ways. Most importantly, the delivery week to week is far superior. The overall story is greater imo. However, these 2 are at the top of my Wednesday reading schedule. These 2 are the ones I am collecting volumes on before all others. Don't compare these 2, just read and enjoy. They are different yet the same and they are both amazing in their own ways. read more
Badass fights, a very big world, friendship and very cool powers. That is what both of these series are all about. The main characters have both lost their parents and are on a quest to become stronger. But they realise that they cannot do it alone, that's why they need all of their friends to accomplish their goals. If you like action packed shonen manga, then these stories are perfect for you!
Both series involve the bonds of friendship, with One Piece involving the relationships between the Strawhat crew while Naruto involving the bonds between the different ninjas of the Hidden Leaf village.
Both have a vast amount of characters that have interesting and unique backgrounds and different environments for the characters to explore.
Both main characters (Luffy and Naruto) are extremely similar as they have the ambition to protect their friends. Also, both protagonists have the ambition to rise to the very top with Luffy desiring to become the Pirate King and Naruto desiring to become the Hokage.

If u like Naruto,you will like One Piece even more.One Piece offers much much more.Both MC are funny and awesome at the same time! The world in One Piece is much bigger and there is much more everything :)
An adventurous tale about a cast of characters. Hunter x Hunter and One Piece have wonderful creativity when it comes to its settings, story, and development. There is depth in the characters with the relationships they develop. Background stories are cleverly depicted and conveys what a classic adventure series should be.
( Sorry english isn't my first language (; 3 ;) )
The Creativity and imagination of both manga are really awesome,
- Both have amazing adventure story
- Both have their own concept of world
- The main character of both manga are really similiar (Gon & Luffy)
- The friendship between both main character and their friend
- The amazing action scene
This starts off rather slow and boring but get's better as you go through it. It's very creative and original and has all sort of great and individual characters that you will like. It has just as much adventure and action as one piece or Fairy Tail. Thogh it may be a little different, it's still worth checking out.
Though it goes on hiatus every so often, it's still worth reading and keeping up with. It was successful in it's prime a good decade ago and is still going strong.
The main characters may not be the smartest people on earth, but that makes these series very funny to read. Apart from that they both contain a lot a action, epic battle scenes and very original and exciting powers. Both of the main characters have a strong determination to reach their goals.
Both Gon and Luffy are funny, not so smart and naturally strong. They are in search for something and they would do anything for their friends. Both series have an amazing protagonists and antagonists.
With a lot of action and detailed story, One Piece and Kingdom has many similarities with each other. Both series follows a main male protagonist who has a set goal in mind. There is a lot of characterization present in their story. Additionally, relationship building and background stories are a pivotal point to both series' success. Expect plenty of plot twists, fighting tactics, and a world with vast capabilities.
I'm surprised no one else has made this recommendation.
Kingdom and One piece is similar in that the main characters are really powerful BUT we join their story to see them grow and become stronger, and both main characters set out to be high ranking person one being king of pirates and the other being a great general. And both manga's have really strong side characters that give a real impact in the story and to the reader, showing that someone who initially looks strange; then becomes such a memorable character. Although the only big difference is that One Piece is fantasy and Kingdom is history, but it could be said that history created fantasy.  read more
Although having a completely different setting and scale, Kingdom and One Piece have also a lot of similarities:
-To start off, both the main characters aim is to achieve the utmost position on their field of expertise, that is, in one case, becoming the king of the pirates, and, in the other, great general of the heavens
- Secondly, protagonists of both series are accompanied by trustworthy subordinates and supporters, earned troughout their quest, that learned to hold imeasurable respect for them
- Finally, both series can be very humorous and dramatic, with an art style that feels, at least to me, very similar in its originality read more
The heroes of both manga share the same personalities: strong, reckless and caring for their comrades. They also share a similar dream of one day becoming the greatest in their own right. One Piece progresses by having tons of adventures, while Kingdom progresses by having tons of warfare.
Both manga also focuses on many subplots as you read further, which eventually leads to revealing mysteries and conspiracies.
At 457 chapters, Kingdom is only a bit over 50% over. Honestly, if you're looking for a story that's on the same scale as One Piece, Kingdom fits the bill more then Naruto or Bleach.
And if you're thinking, "Oh,so it's super dragged out". NOPE. Kingdom is a war manga, a historical, real one actually with fiction added in from the Author to turn it into a really compelling story that you wouldn't want to stop reading until you catch up to the newest chapters. Each chapter progress the battles and wars.
If you like main characters have a huge end goal; and see them work toward it and as they progress not only do they get stronger but also more influential,you will love Kingdom.
Because of a short anime, it hasn't gotten as popular as OP,Naruto or Bleach but this year it sold millions in Japan, Right now Youtuber King of Lightning has decided to review it weekly and it's popularity is only about get bigger. Start reading Kingdom now, and you will unlock the Bonus status of "I did that cool thing before it was cool" status :)
Both mangas just keep getting better and better, both authors dedicates everything they have into the manga.
In Kubera the mood is more tragedy-like while in One piece it's easy-going but both of them can and will make u shiver from excitement.
The advanture in both mangas is tremendous and amazing, the world is interesting and never-ending, you can never get enough of it, the storyline is always at it's best, the sad moments will make u shed tears and the happy moments will bring a huge smile up ur face.
Kubera and One piece are very similar and both mangas are a masterpiece in every way possible, I highly recommend you read both. read more
Both series have a lot in common, both are adventure like, really fun to read, very enjoyable, both creators put a lot of effort in making them, if you had time to read 730+ chapters of one piece you should try kubera as well!
Both will sweep you into the story with a very detailed universe and a unique storyline.
Both are getting better and better with each chapter.
Also,both will make you sad to tears or happy to the point of non-stop laughter.
Great characters and similar vibe of adventure. if you read one of them- you really should try the other.
Mixes humour with fantastical action-adventure storyline. Unlike a lot of shounen, not every character is a teenager; you have a mix of ages and backgrounds (so again, not everyone is at school or some form of ninja school...) which adds a richness to the setting and a feeling that it's more than just generic wish-fulfilment crap like Bleach and Naruto.
As shown in the cross-over between these series, almost all the main characters deal some similarities, so do the villians, the major fights and most of the dialogue's and characteristics of people in the series. The storyline and the art are the things that are the things that are different for the most part, but for the rest, they are pretty similar.
They have almost the same huge pack of originalty, adventure, emotion, epicness and an uniquie style that makes One Piece the successor of the best anime/manga title. One Piece is destined to be as famous as Dragon Ball if it ever gets a decent dub.
One Piece is commonly accepted as being the Dragon Ball of the modern day. Both series start out as lighthearted adventures but then get into some serious battles with a lot at stake. The main characters are similar and both series take place in unique and developed universes.
Extremely long, highly popular battle shounen series that tells of a tale of epic adventure of our protagonists, Luffy and Goku. There are a lot of action scenes, as well as featuring heart-warming moments of friendship and family.
if you love the action and suspense of bleach, you will love one piece. The manga is has the same suspense, action, adventure and intense-ness of bleach except in a different way. In each plot arc there is always conspiracy theories and really complicated plot twists just like bleach. READ IT
Top-notch (at least best-selling) shounen jump manga that epitomizes the concept of friendship, love, self-sacrifice, coming-of-age, amidst action-packed volumes.
Bleach is about death god (shinagami), while One Piece is about pirates.
Both main characters are incredibly strong and aim to become the strongest in the world. But they could never do it alone, that's why they need all their friends in order to help them. Friendship is really important in both of these manga. Apart from that you will also get: action packed chapters, incredible powers and some of the best humour out there!
A classical adventure set up where the main characters are "the bad guys", criminals wanted by the government. Very traditional shounen, with the typical battles, special abilities and powers, and character's dreams. Very enjoyable.
Nanatsu no Taizai and One Piece are both adventure series that chronicles a group of characters as they go on a journey. The main male protagonist possesses similar personalities as we see their development over the course of the series. There is great action, back story, and clever dialogue delivery with its character interactions. As both series also takes place in a fantasy world, expect events out of the ordinary. I recommend both series to who are looking for a classic adventure.
Both are a shonen action / adventure series. The main protagonists in both series' are wanted criminals, who are simply outlaws over actually bad people. Meliodas is like the hilarious offspring of Luffy and Sanji. The art styles use similarly bright colors, that kind of disguise the darker theme of the series. Nanatsu no Taizai (aka The Seven Deadly Sins) is much like One Piece, except with knights rather than pirates, with it's lighthearted-ness and bad-ass cast of characters, and it seems to hold promise for some awesome adventures like those you'd see in One Piece.
Both Nanatsu no Taizai and One Piece similar in that they are both fun adventure/battle manga that don't take themselves too seriously but can still pack an emotional punch when it needs too and are mainly about adventure. They are also similar in that the main characters are outlaws that you can't help but root for.
I can't help but feel One Piece vibes when reading Nanatsu no Taizai (The Seven Deadly Sins). The main characters (Luffy and Meliodas) are similar in that they're both seemingly carefree until stuff gets serious. Both MCs are powerful in there own way and have their own group which they lead. Meliodas' group themselves have an interesting cast of characters, all with their own backstory and reasons for being who they are, just like Luffy's crew. Though Nanatsu no Taizai is still young (not even 100 chapters yet) I feel like this manga can last for a long time because the pacing makes it seem like it will, though probably not as long as One Piece. read more
They both have the same feel and comedy. Soul Eater is about shinigami's and One Piece is about pirates but their comedy and the idea of pushing ones self to be great is seen in both mangas. If you like One Piece you will defintely like Soul Eater and vice versa.
- unique characters with strong will power
- lots of GOOD comedy
- bizzare world
- lots of different settings
- unique and exciting action scenes
- lots of character development
My favourite manga/anime series is One Piece and I absolutely love Soul Eater so I think it's safe to say that they are both very similar.
It begins as an epic adventure with friends travelling, from island to island, from dungeon to dungeon, but soon it becomes a bigger issue that involve world domination, civil wars and abuse against the weak.
One Piece and Magi both follow adventures of main characters in a fantasy world with overwhelming potentials. There is a great deal of world building and character development for both series. And when it comes to action, they are decorative with creative details. The characters also are fun to get used to with comedy employed and the relationships that are shown. More importantly, both series creates the sense of of adventure that stays true to their premise with rich details.
Both manga have a focus on Adventure and friendship. He settings may be completely different, but each arc takes place in a new place with new adventures. Both have a humongous variety of characters, and have entertaining action and comedy. The biggest difference between the two (other than the setting) is that Magi has a larger focus on war while One Piece is freedom.
Both Magi and One Piece are adventure/battle series with a very strong emphasis on world building, comedy, and friendships.
One way I've always liked describing it as that Magi has the world building of One Piece but the storytelling of Hunter x Hunter.
both have a good story telling and lots of action. although the action in Ares is more fast pace and has less senseless talking in the middle of a fight sequence. and the art is more of a sketch then One Piece but once you get used to the art you may realize that it gives more depth to the fight sequences.
-One Piece fights to get the treasure "One Piece"
-Ares fights for revenge
-One Piece has pirates, Ares does not.
-Both main characters are simple minded but extremely powerful
-Both have friends who are powerful fighting by the main characters side
-Both involves traveling and many fights occur as they travel
-Both have something to search for as part of their goal
-Both main characters are willing to help the main character achieve their goal
-Both have comedy, adventure, shounen, action
- Similar feel from the characters
- One leading a large group on a quest of epic scale
- Good development for all main characters
- Many one on one 'boss' fights
- Fighting for great morales, saving the day
Although the theme of Reborn! and One Piece are entirely different, the values they represent are quite similar. For instance, you have the whole concept of "family" in Reborn! which complimenets One Piece's notion of a "nakama". Another similarity is that you have various organisations - different mafia groups in Reborn! as oppose to different pirate groups in One Piece. In addition, each character, in both mangas, tends to have a specific way of fighting. Thus, highlighting another similarity found between Reborn! and One Piece.
The main focus of both series is 'friendship' and the main character's of each manga will do anything possible to rescue there crew/family respectively. Both are also filled with little gags in between the action.
Both series involve the bonds of friendship, with One Piece involving the close relationships between the Strawhat crew while Katekyo Hitman Reborn! involving the close relationships between the Vongola 10. Within those both groups, the protagonists' friends are extremely loyal to their leaders.
Both main characters (Luffy and Tsuna) are extremely similar as they have the ambition to protect their friends.
Both have a vast amount of characters that have interesting and unique backgrounds.
Both series have a large amount of action and use of supernatural powers.
Honestly speaking, if you were to combine Zoro and Luffy into one person (characteristics) you would probably get Oga Tatsumi which is the main character of Beelzebub. Oga's close hand combat will remind you of Luffy's way of fighting and his special rubber attacks for an example the rocket punch later seen. The eyes of seriousness and his attention span is very similar to Zoro's characteristics to the point you'll feel like it's some sort of dejavu. Ah and Zoro's green hair is also applied to the infant. Coincidence? Perhaps. Anyways I highly recommend this to any One Piece lovers. The stories are different however but I believe the concept is about the same. read more
One big thing these two manga have in common is that they both have "supernatural" powers and awesome fights, and are actually quite funny and amusing. They both have twists and new "adventures" popping up all the time, which makes them much more interesting. What makes them even better are the special unbreakable bonds.
(P.s, Beelzebub really makes you think about One Piece's Zoro when you see him the first time, which actually attracted me to reading Beelzebub in the first place, and in addition, the rest of the Beelzebub squad was similiar to Luffy's crew which makes you think more about One Piece).
Shared by both are an amazing cast of colorful characters, side characters more memorable than the majority of main characters, hilarious comedy, moving and often poignant drama, long term character and plot development (as well a plot line beautiful in it's simplicity), fights that succeed in raising one's heartbeat, and buckets of machismo. While, in terms of plot, the series are world's apart, it's hard to imagine that someone could enjoy one but not the other
The characters give off a same vibe, they have same personality's and so on, the story can be viewed the same to, they have a journey ahead of them because of they're certain goal, although the characters have different goals, it leads them all to the same journey
•Both main characters in the series (Luffy from One Piece and Asta from Black Clover) share many similarities.
They also have the catch phrase where they want to be the best.
(ex. Luffy says, "He'll be the Pirate King" while Asta says, "He'll be the Sorcerer Emperor"... every time! So it'll be annoying.)
•The main characters have the "never give up attitude."
•Similar genres (action, comedy, fantasy, etc.)
•Both serialized by Shounen Jump (Weekly), so you'll know it'll be great.
•Both are long series. As of June 13 2016, One Piece has 827 chapters while Black Clover only has 65 (it has significantly less chapters since Black Cover is still new (2015) while One Piece started back in 1997).
Overall both are great. Highly recommended to read it when you get the chance. read more
While at a first glance these manga seem to have almost nothing in common, a person who enjoys One Piece will certainly enjoy reading Detective Conan. Both stories have well-developed characters that the readers will undoubtedly be rooting for; both have a main protagonist that fights for what he believes in, regardless of the danger that may come or the people who may be against him; and both have a central storyline that is suspenseful, moving and impossible to ignore. If you enjoy One Piece's mysterious Void Century and the corrupt nature of the World Government, you will most definitely enjoy Edogawa Conan's adventures.
Taking place in a world with near limitless potentials, One Piece and Magi: Sinbad no Bouken follows the adventures of a daring protagonist who is not afraid to take risks. Both series adapts their journey while meeting allies and enemies. The main protagonists' personalities are also quite similar and often gets caught into conflicts by their own actions. Both series also adapts shounen style fights in spectacular fashion.
Fantasma is a new series, but seems to me to be quite similar to One Piece. Both involve main protagonists whose main goal is to become the top of their field, both involve humorous story telling and action, and both seem to be targeted at a teenage audience.
Both series tells about a adventure around the world (from Japan to Egypt in JoJo and from East Blue to Raftel in One Piece). Similiar fightinig abilities and the main characters have both a funny grandpa who has a lot great fights in the past. And in main crew of both are a Frenchman who is nice to ladies.
The style of action in One Piece and Full Ahead! Coco is very similar, featuring lots of intense attacks from a cast of pretty silly, likable characters. The character design in One Piece is perhaps a bit sillier, but the two series tend to scratch that same itch. Most of all, though, the pirate atmosphere in each series is also very similar, with a focus on comradery and togetherness.
Similarity : MC in journey to find/rebuild they comrade/team
+ Onepiece >> luffy must find atleast 12 peoples to created straw hat pirates group
+ The Legend of Maian >> Felicia in journey to find 13 regis knight (her loyal servant)
A group of people go on a journey to find something, by traveling to many different places (worlds). Characters gain many things, experience new things, and deepen bonds with others. Both reads can get emotional at times, confusing at some times, and fun at many times. Characters are similar to one another, there is a swordsman, an animal, and one who uses kicks in each group.
Both reads are enjoyable, if you've read one and enjoyed it, you may like the other.
The reason i decided to mark them as similar is a thing that takes place so much only in these two franchises from everything i ever saw - antivilains. Both Luffy and Tetsuro like playing role of Jesus by forgiving "bad" guys, making them actually appear to be the "good" guys.
Mister 2 sacrificed himself more times than actually Luffy; Buggy, Crocodile, the son of the Axe-Hand guy and eventually the Axe-Hand guy himself, you remember, they all are now good, don't ya?
In the Express 999 you literally feel sad for every villain killed by the protagonist, when they give him live advices as their last words. And if Tetsuro don't kill them you are left with a faith in the villain that aim to become the Great Bandit to restore society of his homeland.
If you liked the part of One Piece, you should definitely read the Express 999, i suspect Oda took his style from the old stuff. read more
The main hero goes on a great adventure for a grand prize. Both manga have distinct/strange art styles, lots of quirky characters, insanely creative powers, and plots involving shady government secrets.
They don't have similar characters, they don't have similar story lines but what they do have in common is what makes them both so good! They're both well written, both have good plots and both have good amount of characters that have their own stories! If you have read one, then try the other, you definitely will not be disappointed.
Action/Adventure where both protagonist venture to unknown land in search for artifacts. Meeting various people with abilities and gaining comrades/allies along the way. Arata tends to focus more on the character development whilst One Piece is much focus on the adventure and battle though both share common theme.
Both anime's deal with several of the same issues, tho', they're done completely different. Main characters both use long-distance attack in almost the same style, while most of the characters look a like, and the plot has some issues that are the same. Both are completely different, yet, they give off that same vibe.
Both are to do with the main character wanting to be a king and also having to fight will a variety of people with different skills along the way. They have a similar feel to them, even though they are two completely different worlds.
Pirates, adventure, and friendship are the main themes of Lindbergh and One Piece. Lindbergh follows a crew of "sky pirates," while One Piece has sea pirates. Lindbergh has a main character called "Captain Shark" who resembles some characters in One Piece for literally having shark teeth. Both manga are full of endearing characters, fantastical creatures, and old legends.
These two series are different in a lot of ways, but they have a few things in common. For one, both have heavy doses of high quality action and comedy. In both manga, the comedy and the action are often intermingled to the degree that it's hard to separate one from the other. Both manga have somewhat ridiculous characters. Finally, the art quality in OP and AM increases substantially over time, and both art styles take some getting used to. Neither is the typical manga style.
From what has been scanlated so far, I think Air Master lacks the epic plot of One Piece, but if you are a fan of either I think there is a good chance you would like the other.  read more
Well altough the feeling is not pretty much the same till now, you may find a lot of similarities with one piece. If you like stories that revolve around "nakama", wanted posters and a party of people that try to fight the evil this is another good answer for the " what to read next " dilema!
Banana no Nana and One Piece have quite a lot in common, although both are rather unique and enjoyable in their own way.
It starts out with a promise made in their childhood with a fatherly figure. For Luffy it's the promise with Shanks to be a pirate and surpass him (and find One Piece). For Nana and Ringo its the promise with Ringo's father to travel the world (and find Oz). At the age of 16 they all set out on an epic adventure, but soon have to face the first obstacles on their way to freedom.
Both, Luffy and Nana, have seemingly - and comparatively - useless special abilities (being made out of rubber and being able to manipulate bananas), but, with immense creativity, manage to turn it into a fearsome power. They also both seem to be similarly easy-going, yet incredibly reliable and, as the never-giving-up-type, always trying to protect their "nakama" - who Luffy and Nana are trying to gather during their journey - at all costs.
All of that makes for an epic, creative and humorous adventure with very likeable characters. read more
This may seem like a far-fetched recommendation but really One piece and Noblesse do have things in common. For example both mangas:
Luffy gets enemies to be his friends ~ Rei gets enemies to be his friends
Frankenstein is a loyal friend to Rei ~ Luffy's crew are loyal friends to Luffy
Main characters (Rei and Luffy) are always causing trouble for their friends
Friends usually fulfill outrageous eccentric demands of main character (master/captain)
Overall both One piece and Noblesse have gag and are HILARIOUS. You'll be laughing out loud in front of your computer screen which in turn causes your mom to look at you weird but seriously read them. FUNNY AS HELL.
Difference in plots. One about pirate the other about vampires and mutants. read more
Hareluya II boy is a comedic manga just like one piece, however for MUCH more mature people. also, one piece is about luffy trying to become Pirate King, and hareluya ii boy is about Hibino Hareluya trying to conquer the world by fighting everyday punks.
The art style is somewhat similar. So is the humor. Lot of exploration in it. Luffy is very similar to Kakashi in personality. The leader of Man Chicken is similar to Red Haired Shanks. Nami is similar to Dorothy. Artifacts are slightly similar to the fruits.
