Onii-chan wa Oshimai!
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!

img720(https://i.imgur.com/aQIOmb1.png) Onimai is a joy to watch, I don't often find myself smiling just from seeing great animation, this is one of the best production works I've seen in recent memory. It's a labour of love that is maligned by awful discourse surrounding its more "problematic" ele…
Read full review on AniList →Studio 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. W…
Read full review on AniList →Who 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 fran…
Read full review on AniList →Man, can you imagine watching the genderbend anime and being surprised at the ecchi? Couldn't be me. Nah, I was genuinely shocked (SHOCKED) at the first episode of Onimai. Despite not indicating it at all on my anilist, I am a one time reader of the series (back when it was called "Onii-chan is Don…
Read full review on AniList →This review contains spoilers for Onimai. Onimai is an anime which has seemed to garner quite a lot of attention this season. Reception is mixed as discussion ranges from its heartwarming energy to its shamelessly lewd scenes and the animation which brings it all to life. I, however, am hardly con…
Read full review on AniList →Tastefully endearing CGDCT shows consist of a sparkle of joy to highlight your day. Matted within mixtures of racy material and wholesomeness dialed up to eleven the gender-bender genre carries with it its own brand serving as a barrier of entry. THAT'S ONIMAI. Studio BIND may have been formed in re…
Read full review on AniList →Quick heads-up if you're expecting a professional review: This ain't it. These are just my unfiltered and honest thoughts on this show. May or may not contain spoilers, idk. Oh boy, where do I start? Well, let me explain why I even watched this because there is a shitload of reasons, it almost seem…
Read full review on AniList →# ~~~__A WHOLESOME ECCHI WITH STUDIO BIND IN CHARGE__~~~ ~~~~~~ ~~~Winter 2023 has certainly been one of the poorest anime seasons in terms of valid titles, but you always manage to catch something even in these situations. The series I'm talking about in this review is a decidedly surprising show…

Read full review on AniList →Whether you like it or hate it due to the themes it has, Studio Bind has crafted another masterpiece of animation in their relatively new hands as an studio even if not really fully new animators, giving us animation so good that would put MAPPA, Cloverworks and A-1 Pictures to shame in every single…
Read full review on AniList →I will start off by saying that I did not go into watching this show with the intent to really... well, I guess enjoy it as I typically aim to with a new series. I watched it because I saw some hubbub about the censorship in the Crunchyroll versions, and general musings about the show's premise, and…
Read full review on AniList →Some series are so easy to explain why it is enjoyable that it would be impossible to meet the word count for a review here ~~~For example: https://anilist.co/anime/146346/My-Life-as-Inukaisans-Dog/ ~~~ _And I can tell you why I gave it a __7/10 __its literally just perverted, trashy fun. What el…
Read full review on AniList →WTF is this one... Why does this look so good but have stuff that makes me go ehh... It does not make sense. Why? Because these things are usually in one-off episodes and others are not that great. This is actually a quality show. Is it the first one to pull it off? Probably not. So Mahiro gets dru…
Read full review on AniList →A 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…
Read full review on AniList →This is WRONG, absolutely WRONG. But in a discreet and provocative way, firstly uncomfortably funny and later cutely funny, but it's a story about getting another chance at life. Okay, so the story is that after two years of living a hikikomori life, Mahiro Oyama, an eroge-loving NEET, wakes up one…
Read full review on AniList →I have a lot of thoughts about this one. # Why is it creepy *** damnit it didn’t have to be creepy For one, I wish it wasn’t fucken creepy. They always do this, they go a little too far into the realm of gross. He did not have to be all the way into tertiary education. They did not have to be middle…
