FUN FACTS ABOUT THE TITLE---

The title of this doujinshi---*Onii-chan wa Oshimai*---is actually a pun [a joke], or a play on words. When in Japanese Kanji script, "Oshimai" literally means "the end", or "it's over", or "done for", or similar. In the English language, the title translates as, "MY BROTHER IS DONE FOR". But if the title is read in Japanese Hiragana script, ones can look at the "Oshimai" part and read it as "[O] Shimai", which literally means "Sisters". Therefore, the title could be alternately read as *My Brother is Actually My Sister.* The title of the anime version has been selected as, "ONIMAI: I'M NOW YOUR SISTER".

As with so many other FANDOM Wikis, this Wiki chronicling *My Brother is Done For* manga and *ONIMAI: I'm Now Your Sister* anime, is a trangender friendly Wiki. It will tell the story of a transgender character with canon, canon compatable, and fannon/fan-fic elements.

## Overview

Teenager Mahiro Oyama is in every sense of the word a loser. No job. No school attendance. No ambition. No goals. No will to live. They have confined themselves to their room for quite some time now, two years in fact, doing nothing but eating, playing eroge video games, visiting soft-core p\*rn websites, watching hentai DVD's, and sleeping. His child progeny and genius sister, Mihari Oyama, already knowing what is eating away at Mahiro's mind, heart, and soul, desperately wants to help her older 'brother' in any way that she can. So, using her impressive and unconventional 'Mad Scientist' skills in human biology and genetics, she does something quite unusual. Something that is destined to be for Mahiro's own good and change their life forever. She begins transitioning 'him' from an unhappy, miserable, worthless teenage boy, into a cute, attractive, cheerful teenage girl !

## An Original Alternate Telling of the Backstory of Mahiro Oyama for both the Manga and Anime

There can not be any greater contrast between a blood related 'brother' and sister then there was between Mihari Oyama, the sister, and Mahiro Oyama, the 'brother'. Mihari was seemingly born a child genius. At a very young age, she showed the natural abilities to learn quickly, retain that knowledge, and to think critically and independently. She was allowed to progress rapidly through the school system, with her subsequently passing her collage courses, and graduating, by the time she was in her mid-teens. With both of their parents gone (working overseas in a long term assignment in the anime), Mihari was even granted Mature Minor legal status, as well as Head of Household privileges, as the both of them lived together in their own house (\*). Mihari's major in collage was in human biology and human genetics. But sometimes such genius comes with a high price; Mihari takes on an unusual appearance as well as an unusual personality. She wears lab clothes all the time, that is, a cami-style shirt, a pleated mini-skirt, and a lab coat to anywhere and everywhere. She reads noting but scientific journals and peer reviewed research papers. Mihari also seems to delight in taking on the persona of that of a 'mad scientist', and would do unusual and unheard of independent exploration, research, and experimentation into a variety of scientific topics.

Mihari's brother, Mahiro, was almost the complete opposite in his abilities and attitude toward life. Mihari noticed that her 'brother' was born perceived as a male, but was somehow 'different' from what could be thought of as a 'typical' young boy. It took years for Mihari to figure out what was different about Mahiro, especially so because they would never broach the subject, or talk about their deep, inward feelings. When Mahiro began to go through puberty, their life began to spiral downward. He quit going to school. He never developed any close friends. He avoided any social contact with anyone other than Mihari. He was intelligent, but never applied himself to anything useful. He became recluse, spending more and more of his time in his bedroom, playing video games, watching DVD's, and surfing the Internet.

Finally, after the two siblings had been raised together for all those years, Mihari was able to discern what was troubling Mahiro. Mahiro was probably born as a transgender person, born perceived a male, but with their correct Gender Identity being that of a female. With Mahiro's puberty bringing an onslaught of changes to their body that were masculine in nature, one day he remorsefully confessed to his sister that he wished that he had not been born male, would have been able to go through a female puberty, all because their Gender Identity was, and always has been, female ! However, although he has known for quite some time that transgender persons can transition to their correct gender through a variety of means, they were never able to bring themselves to even consider doing so, let alone actually beginning to transition.      As Mahiro's self-confidence and self-worth began to sink lower and lower, and their quality of life decreasing with every month that went by, Mihari knew that she had to do something drastic to remedy her 'brother's' situation, or that situation would surely lead to consideration of a suicide, as is the case with so many teenage transgender persons. Mihari would have to help her 'brother' to transition to their correct gender of a female teenager, but without any help from 'him' at all. Mihari must do it for 'his' own eternal welfare and good well being. . . . elsewise, the unthinkable will happen---My Brother is Done For !!!

## A Skilled Manga Critic Reviews *My Brother is Done For* Manga

Reviewed by Yatsuho & Kil-kun---May 6, 2019

Looking for the best gender bender manga? Well this is the one! You have made the right choice to visit the manga's [Wiki] page.

I had fun reading this manga, the plot is fine, not that unique though. It shows us what being something you're not is like and it's fun! Sometimes I wish I had a life like his. This manga really changed the way I am in real life, it made me think of how I am and what I do. This [manga] is teaching us on what a girl's life is, and it really helped me. Now I know why my hair's messy all the time, and other stuff like that. Like stuff for clothes, and others. This also let me know how to communicate with others, and how to speak to people and become friends with them.
To me, this manga is a life changing one. I don't know [about] you, but this manga changed my life, this is the best.

So this is the story of a NEET- \*ahem\* "In-Home Security Guard"! He was a useless member of the society so to fix that can you guess what his sister did? She drugged him and turned him into a girl (yes, you read that right, physically he/she became a 100% girl)

So this is their daily life of turning the NEET into a normal human. The art is fine, story is enjoyable enough for a weekly or even a binge read, characters are like you'd expect (not that I have any problem with it). Our M[ain] C[haracter] is developing towards becoming a normal member of society. If you let go of Science for a bit, then Enjoyment is plenty. So in the scenario of you having 3-4 hour of free time, I'd recommend to check this [manga] out.

About the art style, I'd give it a 9/10 rating. Why? Because well, the designs are cute and also the main character is too. It is highly detailed and no errors were found when I was reading. It's perfect for me. The jokes were funny. I hope this manga will get an Anime adaptation. Overall, I give it a 8.5/10 ! I enjoyed reading this manga, thanks for taking your time to read my review!
