DESCRIPTION
Mahiro Oyama was just a normal erotic-game loving dude…until he woke up one morning as a woman! Turns out his mad-scientist little sister, Mihari, tried out one of her new experiments on him…with a disastrous outcome, as far as Mahiro’s concerned! But Mihari is as determined to study him as he is determined to go back to his shut-in, game-playing life, and one thing’s for sure…life is going to get a whole lot weirder from here on out!

73/100A Wholesome Anime With A Questionable ExteriorContinue on AniListStudio Bind, you guys adapt the most polarizing things, but boy, does this studio animate things well! From the studio who adapted Mushoku Tensei, one of the greatest isekai adaptations ever, to Onimai, a gender-bending, mind-boggling show, that somehow ended up being a very wholesome CGDCT anime. Without a doubt, this show will be uncomfortable to many, and even as wholesome as it is, the initial premise does sadly bring my enjoyment down a little. Did this show have to be so fanservice heavy at the beginning? However, I will admit that as the episodes went along, they did end up very wholesome and at points, even quite hilarious. I will say though that if a different studio did this show with lower quality animation, I would not have enjoyed it as much as I did. Studio Bind, you saved an anime! Be proud!
Mahiro Oyama is a self proclaimed “home security officer”, who has been a shut in for years, indulging in his erotic visual novels, games, and anything of the sort. His genius sister, Mihari, worried for his well-being, decides to create a medicine that would turn him into a girl, as part of her “rehabilitation plan” for her brother. This show sounds weird, I know, but I had to remind myself, this is anime we’re watching! Other shows get much weirder than this!
In her newfound body, Mahiro has to adapt to being a girl, and that involves many things that I won’t speak of here, but you can catch my drift I think. With that, comes complete over-sexualization and a lot of of fan service, and that put me off this show, at least at the beginning, with how uncomfortable it can be at times.
I do understand what this show is going for, and that is for the protagonist to go through changes to form better and more healthy views towards women, by putting him in one’s shoes. It makes for some funny jokes that land sometimes, but not all the time. I don’t exactly know why the gender-bender was really necessary to make this show work, but it is what it is I suppose. I guess Studio Bind just likes to have protagonists who are otakus who get reformed in some way, first with Rudeus from Mushoku Tensei, and now Mahiro.
After the first few episodes, the show turns into a CGDCT show with Mahiro going to school, and meeting new friends and creating fun friendships. There were a lot of fun and wholesome moments for sure to be seen, and the characters are quite fun to watch, as expected from a CGDCT show.
The animation is phenomenal, to put it lightly. Very well produced and fluid in its movements, and the OP visuals are a great example of this. This show needed the Studio Bind treatment, or else it would have flopped very hard in my opinion. The music is decent, especially the OP and ED, which embodies how insane this show is at times.
Overall, while this show’s exterior is very unfriendly and weird to the average anime viewer, there is a lot of wholesomeness and friendliness to be found here, but this show would have been much better if it didn’t have the questionable premise to begin with, though I’m not sure how that would have worked to fit the themes of the show around rehabilitation. It’s definitely way less of a degenerate show than I thought it was, and while I did have my doubts at the beginning, I slowly grew to enjoy this show for what it was anyway.

43/100Who was this made for?Continue on AniListWho was this series made for?
The tone seems so wildly all over the place and just plain gross at the worst of times. It fluctuates between rather disturbing fanservice almost suited for a hentei and wholesome moments that touch your heart.
ONIMAI: I’m Now Your Sister is a weird anime that I frankly wish was never made as it gives those who hold a delusional hatred of anime without ever even watching a single one ammunition to say “anime’s for weirdos” as if something like the weirdly disturbing ONIMAI is a representation of anime. Sure, anime can plenty of weird, but so can Western shows like Family Guy. Family Guy’s creepiness makes many of the stranger anime look mundane and wholesome by comparison.
But I’m getting off topic.
ONIMAI: I’m Now Your Sister is an adaptation of Nekotoufu-sensei’s manga by Studio Bind and Toho, who’s produced such series like Dr Stone, Haikyuu, Jujitsu Kaisen, My Hero Academia, Jobless Reincarnation and my absolute favourite Teasing Master Takagi-san. They have the pedigree to make something special if they’re given the right tools.
ONIMAI weren’t such good tools
.
It stars Mahiro, a reclusive young man otherwise known as a hikikomori, a form of severe social withdrawal of adolescents and young adults who hole themselves up in their parents’ houses, unable to work or go to school. This honestly had the makings of a beautifully wholesome story about rehabilitation but it gets hampered down so much by perverted, tasteless fanservice that made me question on several occasions who on earth they made this for.
But anyway, Mahiro awoke one day to discover he - or rather she - had been transformed into a girl by her genius, supremely more talented and atrociously fetishly weaponized little sister, Mihari, hence the title I’m Now Your Sister.The two surprisingly share several touching moments that makes me long for the series just to be about the pure innocent bonds Mahiro develops with the rest of the cast throughout her time as a girl without the nauseating perverted stuff. It’s actually quite heartwarming seeing Mahiro struggling to readjust to the outside world from beyond her bedroom and relying on her sister for moral support or when she bakes her some cookies in Home Economics class to show how much she appreciates all she’s done for her.
I just don’t get why the producers shoved in so much fanservice. It added nothing to the narrative and largely took away from it. One episode saw the fetishly-weaponized Mihari bizarrely making a move on her sibling out of nowhere when she got drunk and had to be pulled away by another disgusting sexual creature with unrealistic and disturbing G-cup breasts, reminding Mihari Mahiro isn’t her brother. (Mahiro's true gender was supposed to be a secret the two shared) Mihari then turned her lesbian incest fetish on her, saying “Then you, Kaede-oneechan” before proceeding to pin her to the ground and make out with her.
Yeah, because that’s what I needed in my wholesome anime, a contrived homoerotic make-out session and actual sexual assault!
It makes the writing feel so juvenile and perverse, ruining what should otherwise be an uplifting series about a NEET’s rehabilitation and second chance to do things over and form the bonds she wasn’t able to when she originally attended school as a boy, and the annoying part is, there are plenty of non-erotic, fun and warm moments sprinkled around the horny bits. It leads me to believe they were trying to cater to two different audiences: people like me who want to see a warm setting and people who want eye-candy.
It really doesn’t work.
I can never ever advocate for treating a girl like an object for someone’s sexual amusement and that’s what ONIMAI does, utterly ruining its premise.
Ultimately, I can’t award this series anymore than a 4.3/10, which is a real shame because there’s plenty of touching moments that warm my heart, like when Mahiro learns the agonising pain of her first period and has to be looked after and comforted by her sister or when Mihiri comes down with a fever and Mahiro does her level best to care for her in a roles reversed. Even the previously mentioned sexual object of Mihiri’s bizarre attack, Kaede, gets some pretty good characterization and becomes a bit of a role model to Mahiro.
Mahiro becoming besties with Kaede’s little sister and expending her social circle is also really cute.Animation – It can quite a bit to be desired. They seem to spend much of their budget animating Kaede’s juggle chest physics in an excruciatingly nauseating fashion.
Artstyle – It’s cute. The use of warm colours and bubbles lend the series a tenderness that probably kept me in it because the fanservice making me vomit on several occasions.
Sound – Passable.
OP and ED – Needlessly perverted and horny and I skipped each.
In conclusion: Trying to cater to two different audiences is a recipe for disaster. The wholesome moments will always be bogged down and washed away in the tidal wave of perverted horniness.
Final score – 43/100

70/100A great self-healing anime plagued with fan serviceContinue on AniListA great self-healing anime plagued with fan service
Having just finished Onimai and heading to see reviews, I felt that most people have judged this anime way too harshly, and overlooked the message behind the anime
Mahiro Oyama is a middle-school drop out/shut in that has resolved to staying home and playing videogames, avoiding every social interaction, spiraling torwards self-isolation. Seeing this, his sister, Mihari Oyama, made a special potion that would turn him to a middle-school girl, with the hope of helping him,now her, turn her life around. In the anime, we see Mahiro's everyday life, getting accustomed to the life of the opposite gender and coming to terms with it. She starts to open up mpore and more to her sister, starting to be more and more responsible and starts to build more self-confidence about themselves. Day by day, we see the progress Mahiro makes to go from a shut-in to a more sociable and confident person. It's a great message that even now, if given the chance, with small steps you can better yourself and get back to the life that you tossed away.
Unfortuately, with great anime comes great fan service. Every episode is riddled with fan service, going from forcing Mahiro to dress up to close ups of weird tension between characters where it is implied that something weird is happening, till the frame pans out to reveal a more innocent act. Unfortunately, despite the anime clearly having great message to teach and a rich story behind it, for some reason, the directors have this idea that the anime won't perform to their expectation, so they add fan service to please an audience that isn't suited for this anime. It seems to be a trend amongst lots of great anime like my dress up darlin and gleipnir. I always tend to skip over very lewd scenes and my only justification around it is that it's probably a difference in culture between the west and japan. From japanese reviews that I read, none of them mentioned any displeasure or annoyance to the fan service in the anime.
Though, I feel that some of the scenes that are characterised as fan service are needed. When trying to better yourself, you need to get out of your waters and make some big steps torwards your goal, much like how Mahiro was forced to dress up to get used to feminine clothing, going for a haircut and being forced to take care of her hair to learn to take care of themselves or being forced to go back to school and be exposed to new enviroments.
As for the lewd thoughts from the main character afterwards, I think we need to go try and look at it from the characters perspective. Mahiro's exact reasoning for why they became a shut-in isn't exactly shown, much like a lot isn't known Mahiro's past. The only thing we know is that, Mahiro when he was young used to be more appreciative and caring torwards his sister, taking baths with her, giving her a hairclip as a gift etc. Growing up though, seeing the success of her sister, getting good grades, climbing classes and the praise torwards her, made him feel useless. Being the older brother he was to be expected as the one taking care of his sister and influencing her to be better. Alas, he ended in his sister's shadow, seeing her advancing more and more , while he gets worse and worse. I think all those together could be the reason for Mahiro's weak character. His fixation to pervy manga and games could be his coping mechanism to get back his masculinity. After the transformation, we see that she tries to break her old habits as a man, and one of those is his appeal to the female body. In the start, its clear that she is still coming to terms with it, making mistakes like, peeing standing up, sitting down as a man, despite wearing a skirt. We can see that she is slowly transforming her thoughts to be more feminine and to do that she needs to make mistakes.
In summary, I believe that the anime has a great message that is trying pass along, showing to the viewers that a new change isn't bad, even through its weird way. It's just that the anime is plagued with the common virus that is fan service. I believe that the producers should be more confident in the show's story and overall meaning and to stop appealing to a wider but not correct audience when they fear that the show is gonna fail. Though, if it means that we will get a 2nd season, I'm willing to overlook it. It gets a 7/10 from me
