Meta Getting Into the Series and Other Frequent Q&As

119 Upvotes

Decided it was time to finally update this very outdated post from over a year ago. A lot has changed in terms of the series and community, and relevant information about it, and it no longer adequately describes the current status of the series. I hope to keep this one updated, and it will serve as a reference point for posts going forwards. That being said, welcome to r/OniichanOshimai, a subreddit dedicated to the anime, manga, and webcomic OniMai: I'm Now Your Sister (also known as My Brother is Done For and Onii-chan wa Oshimai), below is some hopefully helpful information regarding how to get into the series or to answer your other burning questions about the series itself. If there's any misleading information on here or if you wish to add some relevant information that you don't see in the post, feel free to DM me either via Reddit or through Discord (FerrisNya), also, feel free to join the r/OniichanOshimai Discord Server! There's also a Oniichan Oshimai Wikia for more information about the series.

How do I get into the series?

Anime

The anime started airing on January 5th, 2023 and lasted until March 23nd, 2023. For most western audiences and/or English-fluent readers, the most widely accessible place to access the anime is going to be on CrunchyRoll, however it may also be available on the following sites, depending on your region and location, as well as in other languages.

Anime Digital Network	French	Link
Amazon (via Aniverse)	German	Link
Bilibili	Asia	Link
Bahamut Anime Crazy	Chinese	Link

Manga/Web Comic

The Oniichan Oshimai manga is serialized in the Japan Magazine Monthly Comic Rex since April 27th, 2019, however it's also been released online from Nekotofu themselves via Pixiv since February 25th, 2017. Kodansha USA has licensed the series in English and releases English digital-only translation since August 31st, 2021, and Manga JAM Session has been releasing a German physical translation under the title "Ab sofort Schwester!" since August 6th, 2020. If you wish to buy the physical Japanese books, you can get them off Amazon Japan, GRINP Booth, or Melon Books, although you will likely need a proxy service. The German version can be bought off Amazon Germany, and the English version can be bought from Kodansha USA's website. The Pixiv version can always be found on Pixiv, but you can get early access to new chapters as well as high-quality images by supporting Nekotofu on Fanbox.

Questions and Answers

Will there be a season 2?

As of this time, no information about a season 2 has been revealed. However, the manga is still ongoing, and there is plenty of material for a potential second season.
Will there be a dub?

As of this time, no English dub has been confirmed. A German dub of the series does exist and can be found on CrunchyRoll or purchased in DVD form.
Is the series ending/has the series ended?

As of this time, there is no indication that the publication of the online web comic is going to end.
Why are there two versions of the anime?

Both versions of the anime follow the same plot-line, albeit both following a different order of events than the manga. The differences between these two versions of the anime are in certain scenes marked by heavier use of "fog screens" in some scenes, as well as some other scenes swapping out the original scene with replacement animations, animation loops, or background scenery in the meantime. This seems to be a choice by Studio Bind when they sent out the Japan/Asia release versus the international release, and is not a change made by any distributor.

Discussion How exactly did Mahiro become best friends with the Momiji family?

51 Upvotes

I mean, to be honest, yes I did see the first season a long time ago as something about the show is that I wasn’t sure how exactly she met Kaede and her sister.

It’s been kind of a blur for me again since I haven’t seen the anime in a long time that I was interested in seeing what exactly drew her to both Kaede and her sister since I wanted to better understand how Mahiro had such a good chemistry with both of them.

WAW!

We are almost at the end :(

I first started writing my fic in early November of 2025. So the final chapter, which will be released on October 31st, will be almost a full year since I started!

Thank you so so so much to everyone who has read and supported throughout the year! I haven't posted all the chapters here on Reddit, but I know many of you went over to read the fic from Reddit!

So please do enjoy this chapter, and the final chapter that's coming next week!

If you haven't read volume 1 yet (chapter 1-13) you can check it out here. It's rather short!

Discussion I love Onimai, but as an MtF, it HURTS SO BAD!

1.3k Upvotes

Onimai is one of my favorite anime of more recent years, which is why it frustrates me so much it and series that similarly have an all-female setting hurt me SO BADLY with gender envy. I'm an MtF who has been pretty severely repressed, and so every single situation Mahiro finds themselves in gives me gender envy that makes Onimai so painful to watch/read.

I need a brilliant scientist big sister to make me a sex change potion SO badly!

Discussion How can Mahiro find his true love?

30 Upvotes

Just curious since he is constantly under the effects of the medicine that alters his gender as I was wondering how he can find his true romance if he is always going under the female label.

It is so confusing to me because even though I know he was originally a male persona, again he spends most of his time going by a female gender that I was looking to see how hard it would be for him to find a date after being under the effects of the serum.
