Main character is a Mary Sue who can do anything and gets all the girls (including his mom motorboating him)

It gets ridiculous when they start writing their own spells because he happens to know the exact values of gravity, melting point and atomic weight of any metal, which is vital to write your metal creating spell which he of course found out since it's logical, right?

I was hoping to watch an old assassin in a kids body doing some cool stuff and struggle here and there in the fantasy setting, instead you get an all-knowing demigod kid gathering his harem and doing everything perfectly. Greeeaaat.

When an author proclaims that one of their works is the best/finest that they have ever written, you'd better take them at their word seriously. It's especially more so from one that has created one of the most controversial works adapted into anime, rightsmack at the beginning of the year: Redo of Healer. That's right, Rui Tsukiyo is once again back on the anime scene, and this Isekai Assassin work that this chill furry dude has so thoroughly written, is indeed no pushover. It's something that feels a lot more like your traditional decent Isekai reincarnation story, with a premise that makes it kinda impressive ...

World's Finest Assassin seems to be nothing special in the genre of Isekai. We have an overpowered MC with anti-hero vibes surrounded by a bunch of cute girls for his harem. It has a dark theme from killing and torture, but fortunately, it doesn't go to the extremes. The fanservice is not the kind where the MC assaults every girl he encounters. The girls show signs of interest in the MC like sneaking into his bed, but the MC simply uses the girls for his mission. Since his main focus is getting stronger. It is more fantasy and action-oriented, surprisingly a well written one, and ...

Ah yes, the beauty of a good adaptation finally….


The manga and light novel of this series are undoubtedly not for everyone , some might argue (and not without reason) that this is generic isekai tash . After skimming through the first 10 chapters of the manga, I can proudly admit that this is one of those rare cases where ….

anime >>LN>>> manga
Probably follows LN to a better degree from what I have heard and cuts most of the questionable ecchi stuff (sasuga author of Redo of healer)

Honestly, I did not expect much after reading the manga and having seen the authors other work i.e. Redo ...

**THIS REVIEW IS SPOILER FREE**

My Opinion
Well, coming from the author of "Redo of Healer" this anime isn't what anyone expected instead it's quite good. It has some of the new elements added to it. And, yeah I enjoyed while watching it.

Story 8
The main point would be does this anime have a good story? I mean yeah sure it does have a good story. Who doesn't like a super badass assassin. The whole point this anime is based on is kinda cool. I mean almost all the isekai shows us how a powerful hero is always good & kind. But, this anime also explores the ...

So far it's just a glorified harem show.

If you can get past the fact that there's only one remotely interesting character that is the MC and that fanservice makes up half the show, then it could be decent.

The sound, art, and story are good, but the fact that it's harem (even though the MC doesn't really show real interest in the girls) just kind of ruins it for me.

It's a nice isekai story and there IS potential but it's disappointing as it's quite clear that they're aiming to appeal to a specific audience that only mostly care about anime girl's visuals and ...

In episode 7, the reincarnated middle-aged man is sharing a bed with two children for some reason - one is a busty childhood friend/servant he once saved from animals and the other is a former captive of a sex-trafficking ring posing as his sister - when they wake in the morning, the two girls smell the MC's ejaculate (yes, they smell it) after he has had a wet dream and the two girls offer to take care of it for him next time, lest he become too "pent-up". In a following episode, the girls have told the mother about this for some reason. She then ...

My parents used to tell me 'life is too short, so make every second count'. Maybe you've heard of that familiar advice before too. What if I told you that the protagonist in this show lives his life as an assassin and takes other people's lives? Sounds daunting, I know. Well, that didn't stop the author introducing us to Lugh Tuatha De, a character who lives by his code and lives his life as an assassin.

Before diving into the juicy details, I do want to mention that this is the same author who wrote Kaifuku Jutsushi no Yarinaoshi. If you don't know what the means, ...

This anime is as good as most people want it to be, and unlike other animes that get boring after the first part, each part progresses. Isekai anime with clever main character.
Story
I do not want to say that the story is extraordinary or that it surprises you, but it can not be said that it is boring and I am 80% sure that you will follow it, because the story has good elements such as different skills. And one of the strong points of the story is the philosophy of the family in which the main character was born.
Art
Good art is just like wanting to ...

I didn't enjoy it.

This show has some high production values in some places, but it is incoherent, as if it is unsure about what it is trying to do.

First there's a fairly stylish intro, which doesn't really match the style of the show afterwards. Then it tediously explains world mechanics. Then there's "splash screeN" of censored breasts (why) of random female character in the middle next to advertisment break. Then it tries to be creepy, then tries to be too dramatic and pushes it too hard, then it tries to be some sort of harem, except that EVERY female character is incredibly stereotypical and ...

The title of this anime is basically the synopsis: World’s Finest Assassin Reincarnated in a Different World as an Aristocrat.

Story: A skilled assassin dies and meets a goddess in the afterlife that’s willing to let him keep his memories in exchange for help dealing with another world. MC agrees to help which is followed by an explanation of the other world and the hero the MC will need to defeat. The twist is that the MC must defeat a powerful hero instead of a powerful demon king. The MC is then reincarnated into the body of an infant named Lugh and retains all of ...

Its such a good concept but is so so badly done, this show is simply generic in every aspect. Hella spoilers

From the overdone fantasy landscape, to the harem its overly garbage. The 2 good points in this are before the mc dies and the goddess bits where she checks in on her hero killer. Everything else is pretty awful.

Its kinda like another cop/doctor show on abc, you know its more repetitive garbage tropes but cmon who doesn't wanna watch it. Anyways, I'm not sure if Rui Tsukiyo knows what the words "world building" mean, actually I'm not sure if he's even trying to create a ...

This show made me angry often. It's the edgiest anime I've ever seen. Story was was written by a teenager. Few examples:
*The MC and his doctor dad do a house call for a sick patient and the dad asks MC what he thought and MC is like "I made sure to take note of his security incase we need to kill him later".
*MC as a child becomes the family head, one of his family members is drunk and challenges him so the MC literally teleports behind him and breaks his arm. And then says "Don't worry. I made sure it was a clean break."
*MC ...

< Concise review >

Sekai Saikou no Ansatsusha is another controversial, although slightly less so, story from the maker of Redo of Healer. For many of the same reasons Redo of Healer has a much lower average score on MAL than it should have, so does this anime. Unfortunately, the anime fandom is filled with tons of easily triggered helicopter-parented adultchildren snowflakes who get irrationally buttblasted whenever a series doesn't cater to their childish sensibilities.

The truth is this show is one of the better Isekai of its year and does a lot of things right that similar fantasy series gets wrong

-The main characters previous ...

Run of the mill isekai harem, but very overrated. Also quite tedious.

STORY is just boring, or perhaps the execution. Extremely slow with nothing exciting.

ART is good, makes the show look promising at first but everything else is just mediocre.

The show promises action but so far delivers nothing, a shameful waste of the concept really.

Girls are powerless and fall for the main character for no reason, character development is non existent for anyone besides main character, the harem bit is meh.

Basic Isekai where a skilled person gets reincarnated to another world to carry out a mission for the goddess. In this case, it’s assassination. No surprises here, he’s OP and his companions are cute girls. The difference is how he obtains them.

Up until episode 6 it was fairly interesting, nothing great but an ok watch. It changed in episode 6, though. It becomes an entire episode of child sex trafficking basically. The worse part is it shows how happy the girls were and then slowly shows how the light leaves their eyes each time they’re pimped. MC has the power to stop this, but ...

Isekais can come in various forms, but one thing is for sure, is that they may end up going about the same kind of plotline of MC or a few, get moved to a new world after their death by some kind of god, and are either given the world, or are told to go on an adventure. With more than likely a possible end goal in sight. This is no different, but it puts an interesting twist on the whole thing, of which may interest someone. So let's get talking about it!

You know the drill, character ends up dying through certain means, and such. ...

The concept i hate the most in isekais is the overpowered character. This one is an attempt of making the same anime you probably have seen countless times, but trick you into thinking the main character was well written.

Don't be fooled. Up until ep4, this anime has had a total of zero decently written characters. I didn't read any source material, so i am only looking at the anime. I still don't get why most reviews here say the mc is a good character. Yes, his backstory was interesting, and yes, to our surprise he wasn't a total NEET loser in his previous life. But ...

The main character is given the objective to defeat the hero in order to save the world from total destruction.

Half way into the series and there hasn't been any further mention, let alone any sort of backstory or proper introduction into this key plot area since the goddess - main character dialogue at the beginning. Not even the side characters seem to know of this so-called hero. For a main antagonist in a story, the world-building is practically non-existent and leaves something to be desired, and also isn't helped by the generic representation of the typical settings found in most isekai titles. If this ...

I don't think I have to explain anything about this.
It's so obvious it's garbage, if you can't see it you're blind (not physically though).

Just a quick and not complete list of critical points:

- The anime is like an Isekai but nothing in his new life resembles his former life

- The girls he saved didn't care about being raped at all after he saved them -> guess they just forgot it happened

- His "sister" wants to f*** with him
