Very similar. At first I thought it was done by the same studio, but I was wrong. Now a "ordinary" guy meets a girl with supernatural powers. In Shakugan this "ordinary" human, Yuuji, is the compartment of the Reiji Maigo, in Kurokami it is yet unknown what role does Ibuki Keita plays, but he "isn't a ordinary human" like Excel says on episode 4. The girl with supernatural powers is forced to stay near the human boy. In Shakugan because Shana has to keep a eye on the Reiji Maigo and in Kurokami because if Kuro doesn't stay close to Keita her fighting abililies decay due to the contract they made. Lastly the "world balance"concept is the main similarity present in both animes, in different yet similar ways. In Shakugan people gets eaten by Guze no Tomogaras and has to be replaced with "torches" for sake of balance. In Kurokami a person's soul divided in 3 parts, each one containing a porcentage of luck (50%, 30%, 20%) to maintain a balance in the world. Yet people try to consume their other part to have as maximium luck as possible. A "Flames Haze" maintains that balance in Shakugan no Shana and a "Mototsumitama"does sort of the same in Kurokami.  read more
They have too similar stories. A guy runs into a girl with red hair who is not really human. He finds out that he is not real from her and then the go on a journey to save the day. The fact that Shana and Kuro don’t seem to have any shame or knowledge of regular social female behavoiur. I was almost confusing the stories that is how similar they are.
Both consists of a main character who's a guy. He meets a special girl with fighting abilities, both very powerful. The guys are somehow bonded to the girls, forced to, and they help fight enemies and such. there are also romantic moments.
These are both fantasy anime about a man who has a contract with a rather skilled girl that comes from nowhere. Moreover, the guy seems really useless at the beginning but will begin to fight along with her.
Both anime are about an average and boring guy who suddenly meets a strong and cute girl who has super powers. The two make a contract together and (initially) have a master-servant relationship, where the girl fights, and the guy is basically useless.
Also, in both anime the main guy is an orphan, and has a childhood friend who is clearly in love with him (Sakura in FSN, Akane in Kurokami).
Both are shounen anime which have fantasy, magic, action, and drama.
Kurokami is more fast-paced and overall better than FSN, though.
In both anime we have a more or less normal male protagonist who makes a contract with powerful supernatural being (or more precisely a girl). As time passes both are trown into a lot of fights and they learn to how to effectively support their supernatural partners (althought they are always supporters and they practically cannot fight on their own).
The story is about a man who make contract with unknown woman because he was in the verge of death,after he was been saved by the woman he is find out about doppel liner system bit by bit then he find out that he was root.although he was not root he still fight to change his destiny.
They both have's similar aspect's like FSN...In both anime's there are mark's on the hand's of the fighter and in both anime's just 1 person fights and the other one give's commands.Very similar stories
These two anime have a similar air to them. Shirou can be compared to Kurokami's male protagonist Keita, as they both enter a world of fighting with beings far greater than themselves. In F/SN we have servants while in Kurokami, we have Motutsumitama. If you like F/SN, you'll definitely enjoy Kurokami
although the ambition of the protagonist in each anime is different but both protagonist character is rather similar very determined despite their lack of power and willing to sacrifice itself to save the people. theres also about forming contract however in kurokami is not a contract between ancient champions but more with a powerful race known as motosumitama.
Both have mysterious people with powers, follower and master setup, making a pact of some sort, and some organization trying to corner the whole battle and the world or something like that. Both have a similar feel to them
Both anime begin with male protagonists trying to save a girl only to have a his heart rip apart. They are later saved by the said girl using supernatural means and are dragged into a lot of fights. Both anime are also set in present day world.
Both anime start with a guy being killed while he tries to save a girl with super powers and in exchange of having their lives saved by the girls, they are dragged into a fight to save the human race.
The story line is pretty much the same. They both have lots of fighting scenes and deal with super natural stuff. However I believe Busou Renkin is a much better anime.
Both of the male leads are thrown in a supernatural and known world where battles are being fought for control of the planet. In Busou Renkin it's the homunculus and in Kurokami its the doppeliner system. Both protagonists start off weak and get in the way of the female leads, but as both series progress they both prove to be invaluable partners.
In both of these series, the main heroine helps the protagonist by saving his life. From then on, they become a partner of sorts. There is comedy, action, drama, and even romance later on in the series. Both anime(s) also has more emotional drama as episodes progresses along with various plot holes. Overall, a good idea to keep an eye on both if you're interested in some fantasy and action.
Random guy who is kind hearted, meets cute girl in random circumstances. Girl happens to be related to some kind of supernatural power, and thus boy gets thrown into a choatic world of fighting, action, complex strange new principles, etc.
The atmospheres are quite similar, and both deal with people who can use certain kinds of magic.
Steiner and Excel (Kurokami) seem to be somewhat like Kanazaki and Stiyl (To Aru Majutsu no Index). They both had confrontations with the main characters and faught to either kill them or take them somewhere (mostly directed to Index and Kuro). Although after awhile, they became companions with the main characters.
Reishin (Kurokami) and Izzard (To Aru Majutsu no Index) were both seen as the main threat, but half way through the series it changes to someone else.
To Aru Majutsu no Index has multiple sets of characters who come from specific 'Church's' and are sent to take out the main characters, while Kurokami have people from different 'Clans', also set to take them out and obtain power.
Kuro and Index both seem to be important to their respective areas. Index being important as she has 103,000 of the grimoires stored in her memory, and Kuro as she is the princess of her tribe. They both encounter somewhat regular high school boys who both have their lives changed afterwards. read more
Both series contain a similar main female protagonist with a huge appetite for food when they first mysteriously meets the main male protagonist.
Both series gets somewhat darker as the episodes progresses.
Both series has a mixture of comedy, drama, fantasy, action, and romance.
Both series features magical battles.
Both anime have a male protagonist that makes a contract with supernatural being to escape death. However, as soon is revealed the contract will kill him in time. Both supernatural beings (girls) have also a goal to achive in this world, for wich they need a contractee (finding a memories in Pandora Hearts and killing a sibling in Kurokami).
Although Pandora Hearts is still ongoing (19 of 25), it has a similar dark feel to the story and also involves contracts between other beings. Instead of Mototsumitama it has monsters called Chains but otherwise just as awesome. Pandora Hearts has a more gothic feel to it.
The main character form a contract with a mitotsumitama(in Pandora heart, it's like chain) to escape death( in P.H., it is to escape the abyss)..
It is also fate that brings them together (apply in both series)...
And also, the contractor of the main character have 1 purpose to live and that is to kill his brother( in pandora heart, the 1 purpose is to find her memories)
Similar plot and background, a girl with super power suddenly appare into this boys life and for whatever reason they sign a contract together and fight against......bad guys
Both series has some kind of romance in it and on top of that the action is awesome
Both series contain supernatural elements with the main heroine being a strange girl with an unique talent.
There is a mystery like atmosphere surrounding both series involving this girl and as the episodes progresses, more depth of both series is explored. Then of course, there is action, fantasy,comedy, and drama. There's not so much romance so if you're looking for such a theme, then both series may disappoint.
Still though, both series are a great watch.
While both series are of different plots, what they share in similarities are the character designs and settings, all thanks to the genius at making shonén/seinén manhwa Im Dal Young. Both series contain action, superpowers, gore and fanservice that even the anti-fanservice lobby can't complain about.
So if you like one, I suggest trying out the other....and if you need more, then try his work on manhwa.
These two shows focus on a series of battles, and despite their different settings, have some noticeable similarities in their mismatched protagonist duo's. Both stories revolve around a pair who is out to change the world. Character relations and the background story is similar for both series.
both have a similar plot where a girl and a guy make a pact where the Guy help the girl unlock their true power. both are VERY similar in that and they have to fight others with special ability and both girls are fighters (Fight with their fist)
These anime are very similar when you are looking at the magical aspects and the style of fighting. They are both very good series that are worth the watch. Even though Full metal they practice alchemy, the style of magic practiced in kurokami is similar and the power used is similar.
Similar action with dark organizations. Young characters with superpowers and similar urban settings.
Both series have the same general feeling. Loaded with action and, at times, emotional character stories.
Kurokami has not the same epic plot as Gurren Lagann, but both of their main characters are battling against their destiny and trying to change it in order to live their lives.
It's supposed that the main character can't change his fate, living bounded to it with the thought that it has to be in that way, but somebody make him change his mind and want to live his life on his own way.
In both series, the two main characters made a contract which is a double-edged weapon: on a side it allows them to be much more powerful in fighting, but at the same time it steals energy from one of the contractors, who gets his life lenght shortened.
Even though Kurokami is focused on super powers and has intense action and drama, while Chrono Crusade is more on the supernatural side and has plenty of silly comedy, both anime have an action-drama-romance mix, plenty of fights, a love-hate relationship between brother and sister, and, above all, identical sad endings.
In both the main guy meets a girl in uncommon circumstances, and thanks to this encounter the guy's life changes drastically, and he gets some kind of super power.
Some characters are similar, and also, the above said girl has an older brother in both cases, and the 2 siblings are part of an important and noble clan/family.
These series are both shounen with great music, animation, and character design, and with well-done, but dragged-on fights.
Both leading males (Lelouch and Keita) have dealt with immense suffering throughout their lifetimes, both lost their mothers tragically. When their lives get changed by mysterious girls (Kuro and C.C), their true potentials are revealed. Both are produced by Sunrise, and licensed by Bandai.
The main character of Kurokami, Kuro, is very similar to Pai in 3 x 3 Eyes. Both characters have a cute/playful side but they also have a dark/dangerous side. In terms of story the shows are also similar so far. An event that occurred in episode 2 of Kurokami reminded me of 3 x 3 Eyes start. I can't say more without spoiling the second episode of Kurokami.
Both are shounen series focused on contracts (usually between a guy and a girl) in which the one who fights absorbs the energy from his/her partner (the Tera in Kurokami, the Soma in SNQ).
Same genres: action, super powers, magic, supernatural.
SNQ has graphic ecchi content, while Kurokami doesn't.
Both have great animation, nice characters, and quite violent fights.
Just to get it out of the way: this 'recommendation' would get a tad technical if it focused on arm loss. In the manga, Kurokami's lead, Keita, loses his arm at the start and has it replaced with someone else's as part of a life-saving contract. In both Parasyte's manga and anime, its lead, Shinichi, also has his arm replaced by another lifeform. So, a superficial similarity exists. HOWEVER, this becomes confusing due to Kurokami's anime being a bastardised version where, instead of arm swapping, HEARTS are exchanged. And in Parasyte... /spoiler
...but I'm not here to compare the two based on arms/hearts. That would be daft. You see, the true similarity is how main characters from seinen manga were altered in more shounenish adaptations. An ignored detail of Parasyte's anime (due to its popularity / ignorance) is how, early on, it was 'modernised' to appeal more to otaku. In the manga, Shinichi didn't wear glasses, nor did he ANGST over Migi's existence. Girls did not gather to blush discussing him. In fact, manga Shinichi acted similar to Kurono Gantz: an average guy dealing with an almost black comedy situation. EVENTUALLY the anime had Shinichi act like his badarse manga counterpart as the two versions sync'd up, but even now it's irksome how the female characters' design / PINK EARPHONES and personalities were altered in order to appeal to... a wider audience.
Kurokami's anime is more of a complete butchering. Firstly, Keita: he's lowered in age so he can attend high school (he's an adult moocher that programs games, in the manga) and changed from a very human arsehole (violent and abusive; usually comically so) to some kind of internal monologuing emo whose only comfort is riding a bicycle alone in the dead of night. ALL of the appeal and comedy is drained by Mr. Average Nobody replacing someone with a naturally dickish yet strangely likable personality. It becomes a different, far inferior series because of this alone. But, unlike in Parasyte, the entire structure of the story was altered and it went anime original BAD. The early Shinichi edits in Parasyte have nothing on how the entirety of Kurokami was ruined: fights even being shortened to the point fighting styles are removed!
TLTR: Seinen manga get an added shounenish edge when turned into anime as their main characters are changed to appeal more to... a certain type of male viewer. You need only listen to Parasyte's opening song in order to gain an understanding of what demographic it was targeted at.  read more
Both anime have a male and female duo.
The female has some special power and bonds with the male to create a greater power.
In both anime the pair need each other to overcome the organizations/individuals that are out to get them.
Though Loveless is arguably rather shounen-ai, both anime involve similar battle systems in that a pair is required to fight to maximize their chance of success, and that one part of the pair fights while the other provides power. Both anime also involve a shady organization that the main protagonists fight against.
