Ichijinsha announced a television anime adaptation of Nekotoufu's Oniichan wa Oshimai! (Onimai: I'm Now Your Sister!) manga on Friday. The publishing company also opened an official website, revealing the main cast, staff, and a teaser visual (pictured).

Voice actresses Marika Kouno (Isekai wa Smartphone to Tomo ni.) and Kaori Ishihara (Irozuku Sekai no Ashita kara) are starring as Mahiro Oyama and Mihari Oyama, respectively.

Nekotoufu originally posted the comedy slice of life manga, also known by its short title Onimai, as a doujin on Pixiv in February 2017 before Ichijinsha picked it up for physical publication in June 2018. The manga began regular serialization in Monthly Comic REX in April 2019. The fifth volume went on sale last May, with the sixth volume scheduled for an April 27 release. Onimai has a cumulative 500,000 copies of its volumes in circulation.

Kodansha USA licensed the manga in English for digital release last June and published the fifth volume on March 22.

Synopsis
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!

Oniichan wa Oshimai! on MAL

Nice. Been reading this since i saw it on thoose Anime japan ranking for "Manga most wanted to be animated" 2020. Cute moe gender bender anime with good comedy.

Studio Bind making another anime? wow.

I like what Studio Bind did to Mushoku Tensei even though I'm not a fan of the anime. But for this moe show, I'm gonna pass.

And when ppl thought Bind existed for adapting MT only

Studio Bind make Moe Anime??

Woahhh... Sign me in

YEEEEES!!!!! FINALLY!!! my favorite loli has anime 💓💓💓

soon these foolish boys will cease to exist they will all perish at my will uwu

studio Bind taking other projects makes me want to appreciate them , the studio doesn’t need to concentrate on Mushoku tensei for a whole eternity but they need to do some extra projects to give a refreshing environment for their production house staffs and make their studio production line stronger .

Studio Bind giving chance to their talented staffs to tryout their debuts in different areas like
Well known Shaft staff who known for his Amazing key animation and direction in Monogatari series :-
“Ryo imamura”(key animator and Episode director) is debuting as a (Character designer).

Another extraordinary Key animator and episode director who is known for the sublime Direction of Mushoku tensei promotional video 1st trailer ( which made everyone to hung upon mushoku tensei without the anime even airing )
Shingo fuji is Debuting as Director for a series for the first time .

Studio Bind gonna make their production pipeline strong and we hope to see some in-house staffs recruiting, Mushoku tensei was mostly done by freelancers.

PS Don’t worry Mushoku tensei still be in a good healthy production cause the Director is Manabu okomoto . We haven’t seen Big MT key staffs names like Hiroyuki takashima, Mizuki takahashi, yoshiko saitou,akira hamaguchi,Miyachi involved in “onichan wa oshimai.”
But the staffs who are working in “onichan wa oshimai” will be also working in mushoku tensei .

Bind doing another anime is defo interesting, and dude transforms into a loli? sure, I have read manga like that, nothing too weird.

Yes please! Though if they could make her hair just a liiittle bit whiter...

The English translation of the title is wrong i think..with my limited japanese..

Oniichan means elder brother... And oshimai is polite form of shimai which means sister...

So the title could mean 'big brother is now sister'..

Heh, Interesting.

yessss I had this in my ptr for a while. It was placed pretty high at manga I’d like to see adapted polls iirc. Didn’t think studio bind would be the one to adapt it though lol

Have read few chapters and it was.. decent enough i guess. Will see the adaptation once it comes out.

The usual reincarnation game that Studio Bind is known for, and who says that they'll only be focusing on Mushoku Tensei? Maybe the head backtracking his speech.

Nonetheless, giving new staff some experiments to try out would be nice to see, lots of debuts from background people.

Haven't read it yet, but while your translation is correct in a literal sense, the onii-chan is the main character so I think it makes sense for the licensor (Kodansha) to translate it that way. There has been a lot of anime that is not translated literally like this as well.

Personally, though, I love how the title is a wordplay of "Oshimai" > siblings and "Oshimai" > end/done; which makes total sense considering the synopsis. Art looks cute too, I'd be looking forward to it.

Let's fucking go!!!!! My fave gender-bender manga, altho in later chapters it pretty much dropped gender-bender aspect and just turned into a moe CGDCT. I'd be happy to see the reactions of this manga's scanlators who always put so much love and effort in scanlating this and always talk about how they want an anime adaptation.

The Japanese title is a double pun. Oshimai means sister, yes, but it can also mean "end" or "something's done for" in a negative sense. So the title can be translated in two ways: "Brother is now sister" or "Brother is done for" (cuz his life as a guy came to an end). That's why 'oshimai' is written in all hiragana and not kanji. The scanlators of this manga took liberty of translating the title as "Onii-chan is done for" at first but when its volumes licensed by Kodansha, the official stylization of the title becomes "Onimai: I'm Now Your Sister!". It's not a literal translation, yes, but it's not wrong either cuz it's the usual stylization for localized English titles.

Read it when it came out. Hyped to see it's getting an anime. Will certainly watch it when it's releasing!

I remember this manga. It's a cute manga but I'm not really interested in watching an anime of it... wait studio bind?

Ok I need to check if they gonna flex animation with this anime or if it's gonna be run of the mill animation.

Finally this studio will draw something normal

>normal
sweet summer child.

omg I didn't expect an adaptation so soon. I wonder if the voices will be similar to the CD Drama

Ah, i get it, so this studio will only adapt degenerate shit, got it! Instant SKIPPPPP!!!

definitely didn't expect Bind to go from MT to this. but it looks funny, I'll give it a shot ^^

Shingo Fuji + Ryou Imamura
I just creamed my pants.


> normal

…….

Nice to see Bind doing something else other than Mushoku.

LETS HECKING GOOOOOO. Actually a great manga no cap I'm amazed its getting an anime though ahaha

I was wondering when this would get an adaption given it's popularity. So ultimately it was just a matter of time. Looking forward to this, but obviously with a bit of skepticism, because there is a good chance not everyone will consider it appropriate, even though there isn't actually anything bad to it. Either way it's gonna be fun to see how much they will adapt and if they'll skip anything.

i hope Bind becomes and stays a goated studio

Funny premise, but I'm surprised that this studio is making other anime....Was hoping that they focused solely on Mushoku Tensei tbh but oh well. I guess this can help add to their pockets if its successful

Gonna check it out just for Bind. Otherwise I would’ve probably skipped.

Yo I didn’t think this manga would get an anime. Can’t wait for all of the new Mahiro faces that’ll come out of this.

If you think an anime version of an experiment from Johnny Test is normal that is.

Excellent choice of voice actress for Mihari though.

Too bad that Studio Bind is wasting time and resources on this.

>Genderbender loli
>cgdct
>Studio bind
>Ryou Imamura character designs

Count me in.

I know that this will be a fun anime to watch.

I didn't realize it from the poster, but... I've read this manga! I didn't think it'd get an adaptation lmaooooo. The English title I read it under was like "Onii-chan is done for".

I thought it was some weird step-sister romance from the title.

I was laughing throughout the first 20 chapters because of how hilarious it is (I rarely enjoy comedy, I only laugh that much when it is Gintama-level of comedy). But I started getting really bored when the middle school starts. Should I continue reading the manga? Moe is not my genre~

Understandable. As much as I love the manga, if middle school part is where you started to get bored, I don't recommend to continue reading it. It's not like gender-bender elements (probably the parts that you find funny) completely disappeared but it's obvious they're not the focus anymore. I think the author ran out of ideas to make jokes out of them.

The plot still progresses bit by bit tho. (Minor spoiler ahead:)

lol imagine calling this anime 'normal'.

I’ve been wanting to read this manga but never got to it so at least I get watch it

heck yeah, i've been waiting for this one yessss!!!!

i hope gender bender will not be the new trending seasonal.

Many eggs will crack

They went from making Mushoku Tensei to a CGDCT comedy, Quite the twist if I've seen one
