On the way home from school one day, Konoha Koga rescues Satoko Kusagakure, a ninja who escaped her village. Soon, pursuers from the village show up in search of Satoko only to be deftly dealt with by Konoha. As it turns out, the unassuming high schooler is actually an assassin. Thus, the potentially cutthroat cohabitation of a ninja and an assassin begins!

If comedy is truly about subverting one’s expectations, then NinKoro is one hell of a great comedy.
It follows the slice-of-life adventures of Konoha, a stone-cold school girl assassin, and Satako, an earnest but incredibly dense, runaway ninja. The unlikely roommate duo initially teams up due to Satako’s lackluster ninja ability to turn objects into leaves, which ends up being a near-perfect method for disposing of dead bodies, something Konoha happily exploits to improve her client reviews and rise up the assassin leaderboards.
The first few episodes didn’t really impress me right away. The gag of introducing adorable, well-designed waifus as assassins coming after the pair, only for them to have three seconds of screentime and face a merciless death at the hands of our disturbingly unperturbed ninja and assassin, is a good bit, but not enough to have me consistently laughing for 12 episodes.
Episode 5, A Robot and Assassin Under One Roof, is where NinKoro really begins to shine and deliver the shocking dark comedy that makes this show so engaging. I won’t spoil it too much, but the episode’s absurd premise involves Konoha caring so little about her roommate that she doesn’t realize she’s been replaced by a robot clone created by her mad scientist assassin rival, Marin. Konoha ends up falling for this robot imposter, and some antics ensue that lead to this episode feeling like an absolute mind-f***.
It marks the first episode in which NinKoro really shows off its ability to not only make you laugh, but also get you emotionally invested, setting up the recurring theme of seeming one-off gags having long-lasting, plot-affecting, psychological consequences for the characters. The way Konoha views Satako after this episode fundamentally shifts, and even takes a while to repair, which was surprising to see from what would otherwise just be another gag in the show.
The real joy of NinKoro is watching Konoha and Satako’s relationship develop. For characters who seem flat at first, they actually grow a surprising amount. This growth is rooted in Satako’s repeated attempts to earn Konoha’s respect and affection by using the most absurdly stupid means possible- such as when she gets Massive Boob Surgery in an attempt to use them as Konoha’s walking weapon storage.
Konoha is extremely aloof and cold towards Satoko at first, but the ninja’s devoted efforts to grow closer to her, even when they backfire spectacularly, challenge Konoha and force her to confront her own emotional walls. Their eventual bond feels well-earned and complex.
I think the best example of this is “A Ninja and a Baby Assassin,” in which Konoha gets turned into a baby (normally not a trope I would particularly enjoy), creating an alternate childhood in her memories where she was raised by Satoko. Yes, the implications of that are as weird as you’d think, especially considering the two have a fair bit of romantic tension going on, but it causes a major breakthrough for Konoha as a character, resulting in some really emotionally hard-hitting scenes in the following episode.
The supporting cast of characters were some real gems as well. Kuro was the Lesbian Wifeguy I didn’t know I needed to see represented in anime. Marin (and later her yandere sister) excelled at both being adorable and chaotic.
Overall, NinKoro isn’t for everyone. Its dark humor can be uncomfortable and provocative, maybe off-puttingly so for some, but for me, it was the most compelling aspect. Silly moments can spiral later on into serious consequences. Like, they still have to worry about all those ninja-assassins they killed plotting revenge from beyond the grave. I’d really hope for a season 2 to be able to see things snowball even further.
I didn’t expect to like this anime THAT much…..
After running away from her village, ex-ninja Satoko Kusagakure is chased by ninja pursuers to claim her bounty. After an assassin named Konoha Koga saves her from one of her pursuers. Satoko chooses to stay with her and help Konoha with her job by hiding the bodies with her ability to turn things into leaves. This cycle continues as Konoha and Satoko continuously deal with ninja pursuers and try to adjust to this new life of living together.
Satoko Kusagakure is an energetic, friendly, and somewhat airheaded ninja. Despite being trained as a ninja, she’s quite inexperienced with combat. However, she’s great with house skills, providing food and keeping Konoha’s house clean. Konoha Koga is a reserved assassin who doesn’t show emotion much. She’s merciless killer who keeps her distance from Satoko while still caring for her as she helps Konoha’s assassin ratings go up.
This anime balances a bunch of elements that wouldn’t usually go well together. You obviously have the “Cute Girls Doing Cute Things” vibe they portray plus the quick, yet cruel acts of murder that repeatedly go on with little to no mercy towards the victims, and then you have those sad scenes with backstories or depressed outcomes. Surprisingly, this anime was able to balance all three of these features and equally portray each of them in a way that doesn’t have one overtake the other. Speaking of cute girls, I really loved the artstyle and animation of this anime. For a show like this, I wouldn’t have expected this to be that well animated. The character designs feel like something out of Magilumiere Magical Girls Inc. and I love it. The comedy was pretty great as well and made this anime more enjoyable. I liked the small detail in the ED where all the ninjas that are leaves become leaves in the ED as well. It’s a small change, but it helps due to its humorous nature.
To be honest, I wasn’t really a fan of episodes 5 and 6 as much as the others. Episode 5 just felt meh to me and really made me dislike Konoha. The robot bit got old really quickly for me. Episode 6 was completely fanservice. FYI, I’m not a fan of fan-service focused episodes, so EP6 just wasn’t enjoyable for me and I thought that it wasn’t needed. Another small complaint I have is focused on the action scenes. Although it was pretty funny to see the fights go by so quickly, I really wished we had a couple more fights where there was some trouble so the skills of the ninja and assassin could show off more.
Despite the cruel acts of the cute girls, I don’t think there was anything downright ugly here.
Despite my complaints list looking like a lot, I really enjoyed this anime way more than I thought I would. It’s silly, it’s depressing, it’s twisted? It’s all of the above! So yes, this is absolutely worth the watch for an emotional rollercoaster.
Thank you for taking the time to read my review. I hope this helped you with your decision on whether to watch this anime or not! If you already have watched it, I hope that you can agree with me with some of the points I made. If you enjoyed this review, I would greatly appreciate a follow too! ^^
