I actually didn't read the light novel, so I'm just giving my opinion based on the anime.
At the beginning and in the title, he is described as the strongest assassin, I imagine that in the future it will be full of murder or something like that.
but that didn't happen AT ALL
In fact, the episode contains him using magic rather than his knowledge in killing.
Some disgusting scenes that are not very important are often shown, such as getting naked to check muscles...
The main heroine here is Dia, at first I was a little attracted to her, she looks strong and has a high curiosity. but in the end... she was made weak and dependent on the MC...
the most disgusting... MC likes Dia but still sleeps in the same bed with other girls. and don't forget the fact that MC is over 60 years old

Sekai Saikou no Ansatsusha, Isekai Kizoku ni Tensei suru stands out as a solid isekai that leans heavily into strategy, preparation, and competence rather than raw power escalation. What immediately sets it apart is its protagonist: instead of the usual clueless reincarnated hero, we follow someone who already possesses experience, discipline, and a clear sense of purpose. This makes the narrative far more engaging, as every decision feels calculated and intentional, giving weight to even the quieter moments of planning.
One of the anime’s strongest aspects is how it balances action with strategy. Fights are not just spectacles; they are often the result of careful setup, resource management, and precise execution. This approach gives the series a more grounded feeling and rewards viewers…

This series drops off in the middle from roughly episode 5 to 9 because too many details don't make it in and the dialogue got far too simplified by how fast it's going. That simplified dialogue does not build much character and threatens to put you to sleep. You are not given a reason for the main character's endeavors in those episodes until after the arc starting in 5 finishes.
Then even though this is quite rushed the anime feels like it ends before we get to the main conflict.
It is not amazing or impressive or any such thing but the last episode was interesting and I do not regret sticking by to see it. Most of de-recs are from people who dropped the series during the 5-9 episode stretch and some angry homosexuals. Looking forward to S2.
Since we got nipples I gave 1 extra point abo…

WOW this show is just some of that great old isekai slop that I LOVE. Assassins are very cool. Assassins with magic... even cooler. The main character is, of course, overpowered. The relationship dynamic between him and his family are pretty enjoyable to watch as it falls into a subplot of lineage.
However, it can get a little weird when trying to explore some other standards of isekai tropes. For example, the fact that the main character is a literal 80 year old man who is reincarnated and proceeds to hang around younger girls and even has one scene where well... he should be getting the treatment that Rudeus gets.
Nevertheless, I like to pretend that the main character just has knowledge of our world and that fixes that issue. Kinda.
Better than your normal isekai.

My Review of The World’s Finest Assassin Gets Reincarnated in Another World as an Aristocrat ;; 6/10
So, this anime promised me a world-class assassin reincarnated in a fantasy land with a mission to kill a hero destined to destroy the world. Sounds awesome, right? Like, finally, an isekai that’s gonna be different and actually interesting.
Well… spoiler alert: it’s mostly just your classic isekai checklist. Magic? Check. Noble family drama? Check. A harem that somehow appears out of nowhere? Double check. If you’ve watched one or two isekais, you’ve basically seen this story before just with a slightly sharper knife.
The main character, Lugh, starts off as this deadly, cold assassin, but once he’s reborn, he somehow turns into the world’s most boring noble kid. Like, I’m still waiting…

This show deserves a MUCH, MUCH higher rating. When I clicked on the listing on MyAnimeList, I was shocked to see this show rated anything below an 8. Pretty much everyone who has watched this show agrees that it is arguably one of the best isekais, and maybe even the best action/adventure anime, that has been released in the past 10 years. Listen, You are probably tired of all of the harems and ecchi garbage and nonsense that is poisoning the field of anime today. You're tired of simp main characters whose sole existence is to live for and get women or "get back" at their high school class for revenge. You are probably tired of the lazy uninspired anime that start off well like Arifureta to just end up becoming a typical harem by the 3rd episode and wasting your time yet again. Well, you…

It is an isekai anime without game-like control panel, pretty much giving a more realistic feeling. The nice thing about the protagonist is that he is not a high schooler to begin with. He started as an assassin of top caliber and almost entering retirement when he died and being reincarnated. He was given a mission and despite given some upper hand such as skills of choice, he was rather severely handicapped against the antagonist. Talk about having 5 skills vs someone with 30 skills. He had no magical weapons and had to build everything up. Surely his greatest strength was his experience as an assassin in modern world.
The character, as he progressed, was very powerful but clearly not the strongest by far. There were several limitations and the character development arc was admirable to…

This is practically identical to Mushoku Tensei, except for the protagonist was reincarnated from an assassin instead of a NEET. It's 4ish hours of greasy, sloppy Japanese wish fulfillment. Thankfully for me, I'm very much an eager customer for that sort of thing.
The protagonist starts out as an extremely skilled assassin, and the episode explaining how he died is surprisingly fun. When he's reborn, he is a no-nonsense child which is a refreshing departure from the usual bumbling crybaby MCs common to the rest of anime. He also has a good relationship with his father which is nice to see. He trains to be an assassin to kill the "hero" who will supposedly become a crazed loon after defeating the demon lord, although we don't actually see any of that in season 1. All we get to see so far…

Well.... I honestly entered this anime with some expectations...... Guess that's on me .
Of course, this show is ... not that bad, and not insulting i suppose,but it's still a dissapointing journey. And when i learned that this same author wrote the abomination that is Redo of Healer, it all makes sense. Even if this anime is much more tame and honestly better overall, it's still plagued by the same issues that show has.A clear lack of imagination on the writers part is the elephant in the room.You create a perfect environment for insane bouts of creativity with the spells in your world, and this guy ends up using some generic gun and knife spells.The MC.... He's not bad, but honestly he ain't that intresting to watch either. And in some way, he's even worse then a hardheaded protagonist…

The show in the beginning was badass. It has a lot of suspension in the beginning episodes, and right until he's released from training to be in this new world, it just turns into an ordinary isekai anime. The premise was there, it was abandoned. The prologue within the first episode was wonderful. It was action-packed, and it had a great hook into the beginning. It flourishes within our eyes.
Remove the beginning episodes, it turns into a normal isekai thats neither bad or good. That's what I'm talking about. They held the ball of a great story and isekai, and dropped it out of the hands; on purpose.
It was a huge blunder, they went into a normal, isekai cliche direction. The foundation and story was already laid out in the beginning, and they didn't commit to it. It felt as if they had…

Go watch Eminence in Shadow. Then come back and watch this.
Without "Eminence" this will be one of stinkiest, insufferable wish-fulfillment edgelord harem isekai dumpster fires.
After "Eminence" this is one of the funniest anime you can watch. It's exactly the same thing except trying to take itself seriously, and so it hits even harder than best over-the-top jokes of "Eminence".
Seriously, watch it. It's so-bad-it's-good gold! Decent animation, nice style, and tropes so cliche, so pulpy you can't help chuckling, the characters so stereotypical, the plot points so edgy and predictable, the protagonist so overpowered, the dialogue so corny! Don't miss it!

Another Isekai anime finished in one sitting (10/03/25).
What makes this anime unique from the rest is that it is the first-ever Isekai I have watched where the MC's former life was given a whole episode before his reincarnation. The way most of the Isekai usually do is to spend the first 5-7 minutes for an accident, murder, suicide, or some other means of transportation into a different world, and bam, our MC gets born into this new world with a slate of cool powers. This anime, however, takes its sweet time in laying the backstory, which gives a breath of fresh air.
Coming back to mature themes, mature in the sense that I do not mean sexual content. These are mature in the sense of themes like drugs, human trafficking, forced prostitution, and political manipulation. But there are some…

It's one of those anime that you are like.... there is so many questionable things that it's unquestionably Japanese.
The author definitely had a thing for sisters.
And a lot of parts, especially that whole ass assassin training rose my eyebrows off my hairline. Like it screams something else. And the whole "treat it as a joke" sexual mentions constantly appearing without cease made me rise my eyebrows off the scalp of my head.
Talk about making a whole ass anime to be constantly inappropriate for so many reasons, especially age.
Anyways. The best of all this anime was like episode 1. And it ceased to be good afterward. It had so much potential but the author decided that plot is just too much a hassle, but harem it is.

This isekai is generic, where the protagonist is strong and surrounded by a harem. However, what I like most about this isekai is that the protagonist acts according to the mindset of someone from his past life who didn’t have many relationships. Even with two young, attractive girls by his side who are interested in him, he never shows any romantic or inappropriate interest in them. It’s mentioned that he visits brothels because he’s still a man with desires. When he eventually kisses Dias, she’s around 18+, and there’s still no malice in the act. This is what sets it apart from most other isekai, where 40-year-old men act like children and are attracted to minors.

I'm OK with isekai anime being cliche. "The World's Finest Assassin" has all these typical themes in it - reborn, choosing of skills, proficiency in magic as result of being isekaied, harem of submissive girls, impressed parents and so on. It's fine.
What can't be accepted is the form. 60/70 years old, grey haired man is transformed into kid. Ok. But why the heck is Lugh acting and thinking like kid. He forgot his whole previous identity? Why steady old hitman acts like 12yr old boy? He makes childish mistakes, losses his temper, is turning red around girls. My complain is that it didn't take much to make this 3-4/10 show into 6/10. Why there isn't his old VA as a narrator of his thoughts? Only his body is young, his soul remained the same.
We watch isekai/tensei anime to see how mc is…

I wouldn't waste your time with this unless you literally have nothing else to watch and are supremely bored.
It's not good. While the starting premise is mildly interesting, the show is mostly boring as hell save for a few moments. Not much happens and the characters are not very likeable.
Also there's one episode in the middle of the show that takes a super dark turn, an extreme vibe change, where you get a solid 20 min reel of human tr*fficing and r*pe. MC saves the victims (yippee!), then the writers proceed to dumpster the surviving companion's character for the rest of the show. I got narrative whiplash with zero payoff with this one.
Another bad isekai but not among the worst of them.

Honestly, I really enjoyed watching this anime. I was looking for an interesting rencarnation anime since I’ve already seen a few and wanted something new. I was a bit worried about starting it cuz of some negative reactions, but to be honest, I realy enjoied it!
It's not the kind of anime you'd seek out if you're after something epic or groundbreaking, but it’s a light and enjoyable watch to unwind with on the weekend.
I was a bit annoyed that almost all the characters are women; it would’ve been better to have some balance to attract more viewers.
Don’t judge it until you’ve watched the whole season, though—there are some awesome moments, but there are also parts that might feel a bit boring. Plus, it’s not really the type of show you’d want to watch weekly; it’s better to gather a few e…

I hate when an isekai try to over explain the isekai.
Two whole episodes just to explain he was a great assassin who was betrayed and then reincarnated.
This could have been done through a short narrated montage.
You dont need an entire episode of a goddess info-dumping. Just get to the point.
Show me how powerful the character is through organic story progression. You dont need to show the audience a check list of abilities.
This is a boring anime, with uninteresting characters, and where nothing of interest happens.
I dont even know what this anime is about. The MC's goal is to assassinate the Hero. But thats not what the anime is about. Its just a bunch of stuff that happens.
This anime is like every other generic zero-effort isekai, except kids get r*ped in it.
Apart from shock…

Just imagine what would happen if the person going to Isekai was a UB Hikikomori, anti-social and just staying at home without a job, the content will definitely be trash with a naive and wishy-washy MC, because there are lots of beautiful girls here, so it's not very suitable for UB Hikikomori to go to this Isekai.
I think this is a good Isekai anime, the graphics, storyline, art style, everything is neatly done, and not just finished to catch up on broadcast time.
The opening song and illustrations also really match the content of this anime.
I hope there will be a second season soon, even though now it's just been added to the database and there's no certainty when it will be released.
I can't wait for the continuation of the story!
At this point, I don't have too many words to descr…

For an anime about assassination, there was not that much assassination.
The World's Finest Assassin Gets Reincarnated in Another World as an Aristocrat is an anime created by the same creator of Redo of Healer, with less provocative content, although still dark.
Female characters are bland, they exist solely as companions for the protagonist, it's not exactly a harem but they can be pretty boring.
The first few episodes were interesting, the protagonist growing up and training, and we get to see his previous life, and how calculated and intelligent he really is.
The magic system is really cool, basically, the saving grace of this anime with pretty great writing, incantation swapping for new spells, and "skill-sets" but not in a super RPG-like way, the magic was well thought out and ma…
