A Ninja and an Assassin Under One Roof — Hey, it's Lv1 Maou to One Room Yuusha, but better in every way! *tilts head with the Essence of Monogatari vibes* Everyday mundaneness. This is the reality that as the sorry-ass humans we are, we go about day and night and do things that sum up the everyday life that seems to repeat endlessly in a body clock's cycle. But what if there is that element that somehow gets you out of that rut and enables quite the spark to life that you can't go one step away from that premise to see life as anything butnormal? This is the outcome and result with mangaka HundredBurger's lone work of Ninja to Koroshiya no Futarigurashi a.k.a A Ninja and an Assassin Under One Roof (shortened to NinKoro), which I think is the better version of Summer 2023's Lv1 Maou to One Room Yuusha a.k.a Level 1 Demon Lord and One Room Hero, in terms of both content and aesthetics.
For as long as time exists, the terminology is one and the same for different settings and aspects when it comes to ninjas and assassins. And although the idea of having them both in communion will, for sure, reap commonality that's unforeseen, that's exactly the case for two rather not-so-ordinary girls, Satoko Kusagakure and Konoha Koga: a ninja who has found herself on the escape route out from her ninja village alongside a group of deserters, and an assassin who is but a rookie at best and trying to stand out amongst the crowd that's constantly executing assassinations and climbing up the regional ranks. What ensues is quite the story of a comedy that hits harder than most but also can inflict some emotional damage in the midst too.
At first glance, it's not all that common to hear of ninjas deserting their villages for reasons one might think of and not. And for Satoko, she, along with the group of ninja deserters led by their leader Kuro, makes an attempt to leave the Kusagakure ninja village in the dead of night and resolves to live the lives that they wanted to live. However, while everyone has got a goal to look forward to, it's Satoko who gets left behind, being one without any money or friends in the outside world and surviving day by night until she almost starves to death. That's where the unassumed Konoha steps in as her saviour, and the two quickly form a mutually exclusive relationship where Konoha will fund Satoko's everyday life inreturn for the latter ninja deserter helping the assassin out on her execution job by turning people into piles of leaves, which sets quite the quick-and-swift comedy, plus taking care of the everyday household duties.
Despite being in the vein of a CGDCT-esque setting (of which this show clearly is trying not to be), I don't know about you, but I'm thinking that how HundredBurger does things here for NinKoro is kind of genius. It's almost like Asobi Asobase, but in a classic slice-of-life setting that, while it doesn't undersell its premise, it provides just about enough "plot" to get you along and then throws you a curveball when you least expect it to happen. From the pure to the gore, and from the funny to the serious, this show will (and I mean WILL) make you feel emotions that are the culmination of teenage angst and a whack-ton of emotional damage that'll leave you baffled at how things got from point A to (not B but) C. I'm telling you, something about this show just screams "it's working" types of unexplainable ruthlessness that just leaves speechlessness hanging at the seams.
To contribute to the wackiness of the premise, there are a fair few entities of note that'll shape Satoko and Konoha's "normal" life of killings, both physically and emotionally. You see, the national assassin rankings are brutal for anyone wanting to make a name for themselves, and while Konoha sits well at the "delegation zone," before Satoko would become a vital resource for her to climb the rankings, even within assassins, there'll be rivalries to beat their own kin at the game. And one of them is Marin Izutsumi, a young mad scientist who sees Konoha as her rival to spy on her and figure out her roots of success, before she'd eventually succumb to the competition and become quite the reluctant friend of the ninja and the assassin. Marin is a load of fun, despite her short-term emotionally broken fuses to hurl her frustrations, and although she can be labelled a tsundere for one (though not exactly that), it's her behaviour that eventually settles for a consensus rather than fighting to have her way. Going back to close acquaintances, you'll find Satoko's leader Kuro fleeing the Kusagakure ninja village, all in the hopes of finding love with her partner, the ordinary human Yuriko, though this relationship has its woes in terms of the former experiencing the "wealth" of the local pachinko parlour and other unnecessary things. And yes, since this fits "within" the mould of a CGDCT, or even towards Yuri territory for that matter, this show has it all, which doesn't distinguish itself as either, but it's also a distinction to not be confined towards the mould.
It's been a long while, but studio Shaft is finally back into the anime scene once again, after what seems like a long drought of not being listed for projects since the failure of Summer 2022's RWBY: Ice Queendom, outside of the studio's mainstay of the Monogatari Series (which saw last year's adaptation of the Off & Monster season) and outsourced work with helping the then-new studio of Bug Films with the adaptation of Zom 100 (which, if you know, is one hell of a production crunch). But this is even more of a promise that getting your work produced by Shaft will have its own visual flair and style, and the overall production looks great, as you would expect, with the cheek to even feature the occasional Monogatari head-tilt style, it being always the undeniable telling of a Shaft-produced work.
Moreover, it's the work of in-house director Yukihiro Miyamoto, for whom this show serves as his lone debut directorial series after the adaptation of the Magia Record: Puella Magi Madoka Magica Side Story series from 2020 to 2022. He's come a long way in his time being tutored and mentored at the studio itself. His narrative writing style can be seen as a vision cut from Shaft itself, which NinKoro fits perfectly into the "somewhere between comedy and despair" style, which Miyamoto is the absolute madlad for directing shows that look depressing but are also comedic in nature.
On the musical stipend, the OST composed by Ryuunosuke Kasai is quite the charm that somehow fits within the eccentricity of the series in both shape and form. And to bring it one step further, both HanaKana's OP and HoneyWorks feat. HaKoniwalily's ED add every bit to the trippiness of the show's expectation-subverting trope that's just all in the name of fun.
A slice-of-life setting that looks all fun and pleasant on the outside, but with unhinged features that provide the constant of unimaginable plot twists? Only in Ninja to Koroshiya no Futarigurashi a.k.a A Ninja and an Assassin Under One Roof, would you find a marriage of all things unconventional while still managing to layer with a facade so simplistic that it doesn't make you suspect anything out of the ordinary.
The very definition of "hook, line, and sinker," I'll give to NinKoro for a feat that it's a damn good watch.

✍️**Personal Opinion**✍️ An anime about an assassin and ninjas! The story is simple—you can pretty much get the gist just from watching the trailer. But honestly, it's hard to describe this anime the way you might expect. For example, calling it CGDCT or just a "cute" show doesn’t quite do it justice, because in truth, it carries a lot of tragic and hidden messages that, in my opinion, were truly impressive. The story is deeper than it seems. The apparent cuteness is actually unsettling when you dive into it and allow yourself to reflect. I had a unique experience with it—it’s special in its own way anddefinitely worth trying. I kept telling myself the final episode would determine if it’s truly worth it, but the anime never let me down. From the first to the last minute, it was thoroughly enjoyable.
This anime has a distinct style and tone that you won’t find in many other series. It combines many elements—subtle social commentary (like the dangers of social media), exploration of friendship and emotional bonds, sudden shifts to comedy, then dramatic and tragic scenes, only to return to cute and lighthearted moments again.

✅ **Who I Recommend This Anime To**
Definitely for fans of **slice-of-life** series, especially those with **all-female casts**, and fans of **short, simple stories**. For the first time, I also recommend it to those who enjoy **deep, layered storytelling with hidden messages**—this anime blends both simplicity and depth impressively.
But most of all, I recommend it to viewers who love discovering **unusual anime**—the lesser-known titles with a unique visual style and distinct narrative voice. Trust me, you’ll find something to enjoy here.
It’s also worth mentioning that the anime contains **fan service**, but it’s very light and actually adds some charm to the show. It's not excessive and feels appropriate for the tone. Fans of subtle fan service might really enjoy this one.
Also, visually and sonically, the anime is solid. The **art style is distinctive and very well done**—especially considering it’s a slice-of-life title.
---
🚨 **Who I Don’t Recommend This Anime To**
Those who dislike shows **with all-female casts**, or those who **hate excessive cuteness, randomness, or shallow friendships**. If you’re bothered by stories where **characters change their beliefs or personality randomly**, this show might frustrate you.
People who hate **“naive” or overly optimistic protagonists** will probably dislike this too. Character development is relatively weak, and the supporting characters aren’t deeply fleshed out. The show heavily relies on its **main protagonist**—so if you dislike her, I don’t recommend watching the anime at all.
Also, to be clear for **Muslim and Arab viewers**, the anime **contains LGBTQ+ characters**. While the anime doesn’t promote this aspect directly, it **does include such content**, so I advise viewers who feel strongly against that to avoid this title.
---
✍️**Conclusion**✍️
I initially thought this would be a cute, simple anime—but it surprised me with its **emotional depth** and **disturbing, tragic themes**. Overall, it was a highly enjoyable and unique experience. I really loved it and gave it a **10/10** because it genuinely made me happy while watching.
For reference, I watched the entire series in one day—the same day the final episode aired—and I found it more enjoyable than if I had watched weekly. I also tried speeding it up to 1.5x or 2x, but that ruined the experience. The anime is already fast-paced and enjoyable as is, and speeding it up really diminishes its charm.
**Enjoy your watch!**

Now this is a comedy done right! Man, what a great pleasure this was. Among all the animes this season, I dare say that this was the one that best delivered the results of what it set out to do.What I value most in a work is whether it succeeds in doing what it set out to do. And in this case, it was delivered masterfully. Extremely charismatic, unique characters, full of personality, each fulfilling their role in the story in a convincing way. Animation outside the standards of anime of this genre, as well as the soundtrack and the creativity of the direction. By the way,I want to highlight the care that was put into the production of this work. The impeccable animation and Japanese dubbing that maintain the high standard of quality are just a few examples that show how everything was done with love, dedication and respect for the work, that already deserves all my respect
In short, in the middle of a season that delivered so many disappointing works, it's great to have something to show us that Japan still has a lot of good things to offer. Thank you to the author, studio Shaft, seiyuus and everyone involved.

A Ninja and an Assassin Under One Roof takes a delightfully offbeat premise—a cold-blooded teenage assassin ends up sharing a home with a runaway ninja—and spins it into a fast-paced, stylish blend of action, comedy, and slice-of-life. It’s rare to see a show that juggles assassinations, shinobi chaos, and everyday chores with this much confidence and charm. The plot is mostly episodic and character-driven, but that works in its favor. The heart of the story is the evolving relationship between Satoko and Konoha, and their growing bond gives the series its warmth. If there’s one shortcoming, it’s that some of the ninja pursuers—many with excellentdesigns—are introduced and dispatched too quickly to leave a lasting impact. Still, the emotional and comedic beats consistently land, and there’s always something fun happening on screen.
This cast is nothing short of lovable. Satoko is endlessly endearing—clumsy, cheerful, and brimming with optimism. Konoha, on the other hand, starts as a stoic, emotionally detached killer, but watching her gradually open up and show vulnerability is deeply satisfying. Their chemistry is excellent, and their transformation from strangers to something like found family (or possibly more) feels natural and rewarding. There’s even a touch of romantic subtext in their closeness, which adds a nice emotional undertone without overwhelming the comedy. Marin is another standout—chaotic, loud, and a perfect contrast to Konoha’s deadpan energy. Even many of the short-lived ninja enemies are memorable thanks to their designs, though it’s almost a shame they didn’t stick around longer. It almost felt like a waste to see such stylish ninja goons drop like flies—but at least they did it in style.
The visual direction is playful and expressive throughout. Shaft leans into its trademark style with flair: exaggerated poses, chibi transformations, quick cuts, and surreal compositions keep every moment dynamic, even when the characters are just doing laundry or cleaning up a murder scene. The action scenes are brief but punchy, often used to deliver comedic payoffs just as much as drama. The character designs are a big strength—everyone looks cute, distinct, and full of personality. Even minor or one-off characters pop visually, making the world feel richer than expected for a mostly light-hearted series.
The music complements the tone nicely, shifting between breezy, comedic melodies and tenser, dramatic cues when the situation calls for it. The OP and ED themes are fun and catchy, though not especially standout. What really shines here is the voice acting. The cast sells the contrast between Satoko’s bright innocence and Konoha’s dry seriousness beautifully, and their performances really enhance the emotional moments. Marin’s VA also deserves credit for bringing big personality to every one of her chaotic scenes.
Even though I gave it a 7 overall, I genuinely liked this show a lot. It’s consistently entertaining, filled with memorable characters, great designs, and a strong sense of rhythm in both its humor and emotional development. Watching Konoha gradually become more open and seeing how Satoko adapts to her bizarre new lifestyle was always rewarding. It’s the kind of show I could see myself rewatching just for the character banter, the visual style, and the feel-good tone. It didn’t blow me away, but it made me smile every week—and sometimes, that’s exactly what I want from anime.
A Ninja and an Assassin Under One Roof is a stylish and heartfelt comedy that balances absurd violence with genuine character growth. While it doesn’t aim for narrative depth, it more than succeeds at being fun, sharp, and occasionally touching. If you’re looking for something cute, quirky, and a little bloody, this anime definitely delivers. A strong recommendation for fans of odd-couple dynamics, expressive animation, and deadly slice-of-life comedy with a soft emotional core.

Ninkoro was one of the weirdest watches of the season for me because on one hand, I liked everyone in this show(besides Konoha), but on the other hand it’s an extremely disturbing story masked by cute cute girls and yuri undertones. It’s a very odd mix of cute girls doing cute things with the backdrop of them killing other cute girls, some NTR and emotional abuse. Episodes will make you laugh, but also make you feel horrible for laughing given what some characters are going through. It’s a unique viewing experience that I had a love hate relationship with. Despite that, I’d say it’s aneasy recommended watch if you like CGDCT or shaft’s production style.
What’s going to make or break this show for you is Konoha and Satoko’s relationship. For me, it started out really cute with some good Yuri vibes and then it slowly started to devolve into an emotionally and mentally abusive one sided relationship where Konoha took average of Satoko’s kindness every week. I hate seeing people get taken advantage of because of how nice they are and that happens a lot towards the middle of this show. Satoko’s clean up ability being crucial for Konoha’s success makes her indispensable, but for a long time Konoha only viewed her as a tool and it angered me so much. There’s even a point where it basically becomes an NTR relationship as Satoko gets replaced by a new character and Konoha doesn’t even notice the real Satoko is gone because this new character does all the same functions as Satoko. This does start to change as the season winds down with Konoha finally viewing Satoko as a human being instead of a cheat code, but man is it hard to watch at times. Some people will probably be able to laugh this off and just go on with the episodes, but for me this part was just brutal.
If you cut that out the story though, it’s pretty good. I’d say it’s a much better version of NEET Otaku from earlier in the year. There’s some real morally grey situations in the story which I appreciate. It can be dull seeing characters who are just always on the right side of the tracks, BUT some of the cases in here were really hard to watch due to just how messed up they were. Innocent people getting hits placed on them, misunderstandings leading to deaths, people being turned into leaves.. this is truly one of the most aptly named “dark comedies” it’s certainly got some hilarious moments, but man there’s always some dark situation in every episode that the show kinda plays off as a joke. Sometimes you can move on from it, other times it sticks with you all day. On a happier note, I’m a huge fan of how unapologetically gay this show is. I knew it had Yuri vibes from the start, but seeing openly gay characters in this was so cool. That relationship is a big part of the story as well and it just fits in very naturally. Hasn’t quite got that far for our main couple, but it’s very clearly going that way and hopefully the manga continues to develop them as individuals and a couple. I did start to empathise with Konoha more towards the end of the show so I could see one day coming around to liking her.
Production wise, Shaft have their fingerprints all over this show. It looks amazing, it’s well directed, great OST and the famous Shaft head tilt is here. It’s a very well put together and pretty looking series.
Final thoughts on this one? Mixed bag. Loved Satoko and the side characters, hated the other lead and some of the edgier stuff, but I overall enjoyed watching the show and would say to give it a watch if you want something different or have a dark sense of humor. Some of the things I didn’t care for you might not have an issue with.
Ninkoro gets 7 kunai out of 10

When this show originally started airing, it wasn't on my radar (for some unknown reason cause this dumb humor is up my alley), but I'm so happy I decided to watch this series cause it was a a lot of fun. The characters themselves are so much fun. A ninja girl who is completely lost on world outside of her village. An assassin who is so deadpan and matter of fact is hilarious. Put them together and it's such a fun duo. They feed off of each other in terms of their attitudes and demeanor and It really shows as the show progresses. They themselveseven get development as time goes on regarding how they feel about each other. Truly, well done 👏👏.
The animation for this show is great. I mean it's SHAFT, duh. they always deliver. But especially for this, It felt extra clean. I'm also just a big fan of SHAFT's directing style with the minimal animation are more about the use of different angles. Really creates for a dynamic scene.
The story itself for this series speaks for itself, in that it's truly just the 2 of them living together and going through their life. It's simple, but the humor and delivery of everything is so well done. And with the introduction of new characters, it gets even better.
Only complaint (if u can even call it that), was that some episodes didn't land for me humor wise (Example episodes 3 & 4). But I feel that's more of a personal problem cause the rest of the humor in this show is top notch 👌.
Overall, I loved it. It's fun, and just a cute little show about a ninja & an assassin living together ☺️ what could ever go wrong hehe

This anime delivered a solid mix of action, drama, and emotional moments, all wrapped in a slick animation style that suited the tone perfectly. The character designs and visual presentation really stood out and added a lot to the atmosphere. The story was engaging for the most part, though it had some rushed elements. The death of Aoi-san hit surprisingly hard — it was one of the most emotional moments in the series. However, some of the other ninja characters met their end far too quickly, making their arcs feel a bit underdeveloped. Despite its flaws, this anime was a good timepass and definitely worth a one-timewatch. It doesn't try to be too deep, but what it does, it does well. If you're into ninja themes with a modern twist and a bit of emotional weight, this one’s worth checking out.

This anime is beside All Perfect Saint and Apocalypse Hotel one of the hidden gems of Spring 2025 Season Anime. It was a wild and disturbing ride from start to end and I love every minute of it. Animation and sound: it's studio SHAFT so expect great animation and a lot of titled heads. xD But in all seriousness animation was fluid throughout entire show, the few battle scenes we have here and there are great and I must praise for character models - each of them are excellent despite many of them having really short screen time. Music is also good, the opening and endingtheme are quite memorable.
Overall animation and music - top stuff as expected form studio SHAFT.
Characters: this is where anime really shines as you cannot decide which character is bigger sociopath. MC's Konoha and Satoko are prime example of this. Konoha is an assassin and if you put a wall and her side by side you cannot say which one is which. While Satoko is funny and dumb to a point where she feels very innocent. The developing dynamic and relationship between them is one of the reasons that makes this show great. As both are sociopaths in their own right and seeing them clash and help eachother in various situation was so enjoyable to watch. Other than Konoha and Satoko we have Marin who is also an assassin but a bit on a dorky side, she was also a great character and her interactions with main two is what pushed show in the right way. We then have LEader and Yuri, a sesbian couple who is also occasionally present to help the main duo. Yuri is stupidly innocent while Leader is a typical good-looking scumbag, but they both work together very well and are fine addition to the main cast. Last one I would want to mention is Aiko, the only 'good' character in the show. Her story in show is so tragic and yet she gives it her best that you cannot but feel the need to protect her. Other characters are also great in design but since they appear for only 1 or 2 episodes they are not impactful enough to talk about them.
Overall MC's are great and really carry the show.
Story: this story is very simple: one day assassin saves a runaway ninja and they form sort of alliance. Ninja will help assassin in disposing the bodies and assassin will in turn defend ninja. From there the story is basically the two of them getting into all sort of situations and developing their relationship over the run of the show. But man... this show may seem innocent and cute but it is so dark it's on the level of Berserk and similar anime. Without spoiling too much I can say that in a single episode show will make you feel doki-doki only to make you feel 'what the f**k' in the next 5 minutes. And some of the dark elements are really dark. If you expected to watch this show just to relax and have doki-doki time then it is not for you. Enter in it prepared to be more shocked than anything, and the show is great in keeping your feelings fluxuating throughout the entire run time.
Overall the story is great but it is not for the lighthearted.
Overall grade: 10. It was a fun ride from start to finish. If they ever release Season 2 I will watch it.
I will also recommend this show as one of the hidden gems this season. Just be warned that you will be more shocked then relaxed while watching it.
