Synopsis

The world's greatest assassin had sworn lifelong allegiance to the organization that raised him. However, despite his loyalty, that very same organization takes action to silence him, ultimately leading to his demise. Drowning in frustration and regrets he can no longer suppress, he finds himself in an audience with a goddess attracted by his exceptional skills. The goddess offers him reincarnation into a magnificent world of swords and magic so he can perform a crucial mission: prevent that world's destruction by slaying its hero.

Accepting the goddess' request, he is reborn as Lugh Tuatha Dé, the son of a noble family of assassins serving the Alvan Kingdom. Under the guidance of his father, Lugh learns new assassination techniques that significantly differ from the cold-blooded and unsympathetic killing style of his previous life. Furthermore, his other talents bloom, allowing him to meet new allies and acquaintances. Even so, Lugh knows that his efforts are far from adequate, because a monumental adversary such as the hero can only be defeated with perfection.

**THIS REVIEW CONTAINS SPOILERS**

Somewhere between the release of .Hack and the year of 2013 the isekai genre devolved into a downwards spiral of recycled ideas being vomited out by any studio looking to make a quick buck. The World’s Finest Assassin tries to break free from this cycle, spicing up the genre by making the protagonist a world-class assassin instead of a loser otaku. If that isn’t enough to satisfy you, he’s also an anti-hero with the mission of bringing down the hero of the world. Apparently, any slight change to an isekai is enough to get an A+ for originality from the anime community.

You ... know, sometimes I feel bad for isekai protagonists. It must be terrible having every single girl in existence want to get inside your pants. Lugh is such an attractive human being that even his own mother can’t help but be strangely obsessed with him. It’s honestly quite impressive, he only had to manipulate 2 girls to swear absolute loyalty to him, and they’re so dedicated to him that they’re even willing to clean up his wet dreams for him. If that isn’t true love, I don’t know what is. In case you were thinking that his actions are morally wrong, don’t worry. His emotional manipulation is definitely 100% only for his mission. He would never actually have perverted thoughts about minors… except for a wet dream when sleeping with two of them… and he might kiss one… and get excited at seeing them naked… but besides that he’s fine!

The producers for this anime are absolute fucking geniuses. Airing this at the same time as Mushoku Tensei’s sequel is such a brilliant way of avoiding controversies. Who’s gonna worry about this 60-year-old assassin sleeping with kids when Rudeus motherfucking Greyrat is running amuck on the front page of every social media site. This is by the same author as Redo of Healer, so it’s damn right the boundaries are going to be pushed at every chance possible. There’s some child trafficking themes (which by the way, are handled fucking horrendously), some pedophilia, and overall just a little bit of something for everyone. At the end of every episode, I thought to myself, surely this can’t get worse. But it did. It got worse with every new fucking episode. The production team knew it too, the initially good art style visibly degraded the further the season progressed. It was a smart move including numerous still shots of naked girls to take up screentime, why worry about animation when there’s some nudity on screen. Why doesn’t the author just make a hentai? The world may never know.

Anti-heroes can be a great part of an anime if done correctly. They can push character decisions and motives past being a basic right or wrong. They can allow the viewer to question their own sense of morals through the actions of another character. Or sometimes anti-heroes are just included to look cool, which is essentially what World’s Finest Assassin does. He’s a professional assassin, the finest even, that never feels much attachment to the lives of others and is willing to do whatever is needed to complete a mission. There are, of course, no consequences for this because it wouldn’t be cool if a badass character suddenly cared about the act of taking a life.

The rest of the cast are forgettable. I was hoping that the world’s hero who our assassin protagonist was supposed to track down would be at least interesting, but they end up being a no-show for the entire season. The main harem basically consists of a servant girl, a girl of nobility, and a well-spoken ara ara girl. Unsurprisingly they’re all painfully bland with their defining personality traits being them wanting to suck off the main character. You’d think that severe mental trauma from witnessing your friends get raped as a child would be quite a life-changing event, but apparently not in this anime. All is solved after the protagonist shows up, buys a girl being trafficked, and adds +1 to his collection of love interests. By the way, the main love interest is also his cousin. You can’t make this shit up.

Audio-visuals are passable. As mentioned before, the art has a pretty noticeable drop as the anime progresses, but it never gets to the point of making the experience worse than it already is. The opening is pretty overrated but at least it’s unique and not just another copy-paste of an existing isekai theme song. None of it really matters though, as this anime would still be a 1/10 even if it had the greatest damn visuals of all time.

“The World's Finest Assassin Gets Reincarnated in Another World as an Aristocrat” is another awful isekai that desperately tries to disguise itself as smart and original. It shouldn’t even be worth a full review yet here I am, actually putting some thought into the meaning behind something that never had any thought put into it in the first place. For the love of God, avoid this if you have any sense of human decency left in you. At least other similarly trashy isekai have some self-awareness.

This is a straight 1/10 and it isn’t even close.

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 ... to boot.

Isekai reincarnation stories, as we've seen over the past year or 2 have realistically boomed up, with a lot of varied concepts from being the stereotypical hero to even animals of all kinds, and this booming trend will continue to be very popular as time passes. This is as such with Rui Tsukiyo having his combi-quasi idea of an Isekai reincarnation story about assassins and aristocrats, and the setting being in medieval fantasy times, both themes are a good fit in the overarching story where the plot is as such: "Kill the Hero who is prophesied to destroy the world."

And that's where the story starts with the protagonist: an old man who has the distinction of being the world's No. 1 assassin working for the organization that he is very loyal to, only for the same organization to belittle that same loyalty in order to assassinate him in the same fashion as how "Tantei wa mōu, Shindeiru." started with the plane situation circumstance. This old man's days are numbered due to his old age, and his usefulness is counted to nothingness as death sets in quick. In a twist, the reincarnation stage opens as the old man transitions into the afterlife, where the usual God entity (in this case the Goddess) has a mission to assign to the rebirth character (the old man) to eradicate the Hero who has a duty to destroy the world after the usual "defeat the Demon Lord" debacle. Of course, being an accomplished assassin, and in the witness of the Goddess, with the choice to experience a life of happiness as opposed to the suppressing of emotions from his real life's stints, how can he say no? And there sets the story and plot as the old man is rebirthed as Lugh Tuatha Dé, the son and heir of an accomplished family of spotless assassins with a license to kill and leave no traces of evidence for all of their advances. Assassins are humans, not tools.

Lugh being a newborn child from the hands of his parents Cian and Esri, the life of an assassin must be hard-coded from young, because when your child has a distinguished name like Tuatha Dé, expectations run high stemming from the offspring from all who've come to expect what the House of Tuatha Dé can do. And that's exactly what both parents did to nurture Lugh's growth as he grows up into a fine assassin and bearing the Tuatha Dé aristocrat name, being aware of their actions and to separate both family and missions when it comes to the crunch. Not a bad start for Lugh since the Goddess has accepted his reincarnation with all of his memories intact, and as you'd expect, Rui Tsukiyo's writing is really succinct and rarely ever feels like it's an aberration of Redo of Healer, even with the subtle sexual innuendos (which really flood the manga adaptation of the LN intentionally) that he knows where to draw the line between enjoyment and going too unintentionally sexual. Really though, well done for writing such an intriguing story plot, even if it's decent by Isekai reincarnation standards, and coming off hot from the less-than-stellar Seirei Gensouki last season, this is practically IMO the superior version overall.

Alas, what's a story without its characters, and Rui Tsukiyo deserves another round of accomplishment from being really careful not to cross the line with the representation of the characters that follow the illusive assassin, who's looking forward to enjoy life to the fullest and not see this new second chance of a life as yet another "used as a tool" narrative. The loving parents of Tuatha Dé, father Cian and mother Esri are parents that if I was reincarnated in another world, I would choose them regardless of their profession. They are trained in the Tuatha Dé fine arts of assassination, and thoroughly execute their duties as instructed when clients come to them who need their assassination aid. Being proud parents of Lugh when he manages to slowly but surely surpass Cian's teachings and Esri's cooking and proection (through uh...boobs I guess), this is the standard of a family that knows what's good for their offspring and nurture to the best of their parenting abilities. A cruel assassin family that otherwise, displays the exquisite affection to all.

You know the deal with OP MCs and a harem, these 2 have to come together like it's the iconic standard, and Isekai Assassin is no different in that regard. Lugh by himself is a sensible and tactful OP MC built upon by the standards of the Tuatha Dé family, and just like his real life counterpart, oversees the assassination missions from start to finish, leaving no trace or footsteps whatsoever. He is supported by his team of waifu-worthy assassins nurtured by him: Dia, Tarte, Maha. Dia being the very first girl that he met when he was young, and being young meant that he had to pick up skillsets on the double. That's where Dia comes in to teach Lugh magic, and seemingly so, because she is one of the most powerful mages in her kingdom of Swiogel. Alas, things aren't meant to be, and they're split up due to her kingdom's political turmoil...which next leads to Tarte. A mage who is saved from her poor background and coming to the Tuatha Dé region for a better life, the coincidental meeting solidified her position has Lugh's assistant, being taken in immediately to be trained by him as an asset for the Hero assassination mission. The hopes of Lugh being formally inducted as the head of the House of Tuatha Dé leads both him and Tarte to yet another girl: Maha. Her chapter oozes close similarity to Redo's revenge plot with her orphaned friends, that like Tarte, was just living life by, only to be caught by rogues and used as prostitutes. This caught the attention of the now new Tuatha Dé head and his new assistant, and just like any other assassination mission, executes the plan to intercept as an aristocrat and save Maha and her friends out of the traumatizing situation that has happened for quite sometime. And there you have it, the assassination team of Lugh Tuatha Dé, that as much as it tries to inject the sexual innuendos as bait for the potential harem, Lugh just doesn't think of them as tools but companions in need to fix a grave situation. A chad MC that has the interests of people as a whole and not so much a harem playboy displaying unequivocal love to his one true love, that speaks volumes more than other harem shows of having girls swarm the MC for attention. Props for equality as character development in the most badass resilient manner.

Silver Link has always been the de-facto standard when it comes to Isekai reincarnation shows, because the studio has clearly been able to produce decent adaptations under budget constraints for quite sometime. With Isekai Assassin, there's another outsourced studio (Studio Palette) to help with the production values, and dare I say that it evokes the same visuals as Seirei Gensouki on face value, but does everything up to 11 to amp up expectations, and this is thanks to in-house director Masafumi Tamura, whom with the failure of Spring 2019's Kenja no Mago, made one hell of a comeback with last Summer's Maou Gakuin. In fact, knowing that he directed Maou Gakuin before should give you the feel that expectations CAN be met that the work together with script and series composer Katsuhiko Takayama (ef: A Tale of Melodies) amplifies the LN as a whole, and from my view, that is a relative success.

The final segment of the music department, and once again, Isekai Assassin gets a massive W for this. Yui Ninomiya's "Dark seeks light" for the OP is really good, maybe even up there as some of her best songs ever composed. Same with Aira Yuuki's ED which more than her mellow sung voice, is a well-made closing song through and through. Rarely do I ever feel that the OST ever misses, and for such an action-pumped series like this, the high octane moments make you feel like you're on the kill scene, being one together with Lugh on his assassination expeditions everywhere.

Like Mushoku Tensei, I'd feel that Isekai Assassin is now part of the rare breed of LN adaptation perceptions that the manga adaptation (of the LN) is just bad, the LN is the original source material that can be referenced to, and the anime is essentially the best version overall. Bear in mind that this is still the Redo of Healer Rui Tsukiyo himself, so all the perceptions from the previous work will undoubtedly shift into Isekai Assassin, but just take a step back, and you'll see an Isekai that's not dogshit and is some trash-worthy freaking goodness in the making. This is truly the pinnacle of Rui Tsukiyo's works, and I'm eagerly looking forward to the next controversial adapted series to come out of this furry's wide catalogue of his many written works.

***THIS REVIEW CONTAINS SPOILERS***

The World’s Finest Assassin Gets Reincarnated into Another World as an Aristocrat is an isekai that’s centered around an old, about-to-be-retired assassin who gets himself killed by the very “organization” he was loyal to during his final mission. Just before he was destined to die, he was reincarnated and placed in front of a god, which the entity tasked him to slay the hero of her realm. As it’s said by the entity herself, if the hero wasn’t slain, the hero would bring destruction and annihilation upon the world in which he saved.

Well, that would have been the plot of the ... series if it actually intended on carrying out its original narrative.

Cause once the former assassin was reincarnated into a new family of assassins, he was given a new identity: Lugh Tuatha Dé. Under this family’s name, he was rigorously trained by his father to be the best assassin in the vaguely touched upon Kingdom in which they resided. Lugh was obedient. As a former assassin, he does everything that his father taught him to do. Besides his usual training, he also had to learn the ambiguous magic abilities from Dia, the instructor/teacher. Except he was bestowed with all the magic skills when he was first summoned into this fantasy world. Everything that Dia instructed him on was everything he already knew. So what it ended up being is just Lugh showing off his skills apathetically to his instructor and the viewer of this anime for an episode. This type of presentation is seen everywhere in these generic isekai anime, which is why it makes them mind-numbing to watch. And in the desperate attempts to incite any sort of emotions and reactions that are falsely representative of the viewers, the series has Dia, Maha, and Tarte, aka, Lugh’s harem, to perform the tedious, over-the-top, and irritating admirations of him. Now, this usually might not be a problem because after all, these tropes have been done many times. But this type of lazy-ass presentation does add up to everything else that’s appalling about this series.

The World’s Finest Assassin comes from the same author as the infamous work: Redo of Healer. If there’s anything to be learned about this dipshit is that he’s obsessed with the concept of rape, and he incorporates it into his narrative in a way that neglects the responsibilities regarding the real implications and consequences.

Maha, before she was recruited by Lugh, was kidnapped along with other girls to a secluded area where nobody could reach them. In there, Maha and the other girls were basically fed like pigs so they could be used as sex objects to god knows what. This single episode in the series went out of its way to demonstrate how each of the girls were mentally and physically destroyed each day after being raped. Although this part of the depiction was seemingly handled with authenticity and care from the author, it’s the conclusion that ultimately turned everything that the girls went through meaningless, and disclosed the true intention of the writer. After Lugh exposed the sex traffickers and had them detained, the girls were suddenly uplifting and completely erased of their past trauma. They were written off as a one-note thing. They were used so that Maha was the only one left in the group who was saved from what they'd gone through to justify her being part of Lugh’s harem. But the real issue is that the girls and Maha were used to blind the viewers from seeing through the real thing: The elements of rape, sexual assault, and human trafficking were ill-handled not only in this garbage of a series, but in today’s Isekai anime in general.

You could say that anime is fiction. You could say that I’m being overly dramatic about all these things. But in my eyes, if a series is to incorporate these elements, it’s the duty of that particular series to handle these real-world systemic problems with the utmost care and justice.

As it is common with these self-insert isekai anime, the protagonist is portrayed to be this smart and witty man. He can solve any conflict of affairs with ease because of the author’s pretentious writing. The world which Lugh inhabits has never encountered the product of moisturizers because it just never existed even though the fantasy world was very well into the likes of the late middle ages of our own, and that the usage of moisturizers was long-established of our own. Because Lugh was the first one to have invented a moisturizer, he was able to successfully form a business selling his novelty to quell the disputes between a noble house and his. The writing then treats this as an absolute accomplishment by touting Lugh to absurd heights. It may look like I’m nitpicking, but I swear I’m just highlighting the moronic writing that’s dispersed in this series.

The World’s Finest Assassin is just another installment of abhorrent works by the infamous author, much like his other notable works, it offers nothing of value in not only its writing but enjoyment as well.

Score: 2/10
