Mahiro Oyama

## Background

Very little childhood or background information on Mahiro Oyama is provided or recounted by the author Nekotoufu, in the manga *Onii-chan is Done For.* What is known about Mahiro's background is mostly obtained from implication, speculative deduction, or conjecture, based on her conduct and the past references she makes after she was transitioned to that of a teenage female. Mahiro was born perceived as a male, but probably had a female gender identity. Being raised as a male seems to have been a non-sequitur and a social irritant, resulting in a gradual decrease in their enjoyment of life. This lead to Mahiro, during their early teen years, to begin spiraling downward mentally, emotionally, and socially. So much so that they dropped out of Middle School, became a 'trashy Hikikomori NEET', and stayed isolated in their bedroom for about two years, mostly watching hentai videos and playing eroge video games. Such is the situation when the story begins, and Mahiro is introduced at the beginning of the story, when after a modern day miracle has occurred, and she awakes and sees herself for the first time as a cute teenage girl.

## Appearance

Mahiro's male appearance is never shown in the manga, except for one scene where they are shown with their back to the audience. The story begins with Mahiro already having the appearance of a typical cute teenage girl. How much of her appearance is due to her physical attributes that she already had, or how much is due to the influence of the drug that she was given, is not explained or shown in the manga.

Mahiro was a bit short for a typical teenage male, but her height is just about right for a teenage female. She is the same height as her sister, Mihari. Mahiro has a good body proportion of size to height to weight, which is very remarkable given her unhealthy male existence. Her face is very round, with a shallow chin and temples, and a small neck. She has full cheeks and cheekbones, adding to her roundness. She always seems to be blushing. Her hair is very long, straight down to almost the small of her back. It seems to have grown really fast after she began ingesting the drug. It is a light gray to white color, with light lavender highlights. A curly but unruly lick of hair is always standing up on the top of her head. Mahiro has 'manga girl' big eyes, in a fawn / light brown eye color. Mahiro early on had rather rapid bust growth, but it soon tapered off to just average for a teen girl. Her bust is larger than Momiji's, but small than Mihari's, her sister. She has small hands. She as an even skin tone, ranging from beige to a light tan. She has nicely shaped legs, and small feet.

As shown in Chapter 2, Mahiro's style of female attire was selected for her by her sister, Mihari. That fashion style can be described as upscale casual, with a heavy dose of kawaii ( extreme cuteness ) influence. After her transformation, Mahiro first began wearing little girl style sundresses. She then moved into wearing nice blouses and pleated mini-skirts, with knee-high socks. Later, Mahiro began to wear black tights with all of her outfits. Her wardrobe continues to grow, as Mihari seems to add pieces and outfits to it on a regular basis. Regardless of the particular outfit, Mahiro always wears either a dress or a skirt. However, when Mihari wants the both of them to take up jogging, Mahiro gets a new warm up suit; a shirt, jacket, and a pair of running shorts as well as a pair of sweat pants. Mahiro's first bra was a sports bra, but she also now wears a regular bra. When Kaede and Mihari go shopping for new swimsuits, they both select bikini swimsuits, and they both facilitate ( intimidate ? ) Mahiro into selecting a bikini swimsuit for herself. Finally, when Mahiro begins to attend Middle School, she begins to wear the Middle School's female school uniform, consisting of a below-the-knee hemline jumper dress worn over a white blouse, and black tights.

## Personality

**Perceived as a male**

As with Mahiro's male appearance, not much is told in the manga about what Mahiro was like as a male. Most of the information is presented as references or as implications from comments that the two sisters make to one another. The most telling aspect of the personality is when Mihari calls them a 'A Trashy Hikikomori N.E.E.T.' This means that Mahiro was, at least for over two years, a social outcast and recluse that completely confined themselves to their bedroom, with no outside contact, other then with their sister. It also meant that Mahiro was unemployed, not going to school, or not getting any job training. Their main interest in life was only that of playing eroge ( X rated ) video games, and reading hentai ( X rated ) manga. As Mahiro's self-confidence and self-worth began to sink lower and lower, and his 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 his correct gender of a female teenager, but without any help from him at all. Mihari would have to do it for his own eternal welfare and good well being. . . . elsewise, My Brother is Done For !!!

**Transitioned to a teenage female**

Slowly but surly, Mahiro, with the help and encouragement of her sister, begins to discard the negative male traits that up to that time governed their whole life. Female traits, as well as good, positive mental and emotional traits that everyone should develop, are introduced to Mahiro, one by one, in the days and weeks following their transition. Mahiro has always had 'a mind of their own', but Mahiro also had always had a faith and trust in the abilities of her genius sister. This trust is probably Mahiro's greatest personality trait. But it has a detrimental side, in that Mahiro is easily lead into ideas and situations based on that trust. Thankfully, Mihari has no unworthy agenda, and only wants to help her sibling, in order to stave off a certain suicide. Early on, Mahiro had to develop the necessary social skills to be able to go out in public, function well, and be around and with other people, especially with girls approximately her own age. In spite of being a recluse, Mahiro finds that developing a friendship with other mild-spirited teenage girls can be a satisfying experience. Thus, friendship becomes a new but stable part of her personality, and a good influence on her. However, the fear of being in groups of people, strangers, out in public was always a part of her negative social status, and thus continues to be so, although she is slowly getting over being afraid in public.

Mahiro proves to be very teachable, as when her sister begins to revamp their personal habits. So unlike their previous habits, Mahiro is taught to regularly bathe, and to wear clean clothes. She even begins to learn how to wash her own clothes ! When the time comes, Mahiro is taught how to handle her monthly period, as well as keeping her spirits up during that special time. Mahiro gradually learns to accept and to implement self-respect and to shoulder personal responsibility for themselves. As that aspect of her personality grows, she comes to realize, with a little help from her friend Momiji, that she needs to abandon her interest in eroge video games and hentai manga, and to dispose of her extensive collection of such kept in her bedroom. Thus, *Agape Love* begins to take hold of Mahiro's personality, perhaps for the first time in her bespectacled life.

Sometimes, Mahiro's personality is a study in contrasts. She can be self-centered, as when she so desperately wanted to obtain the Gacha premium, as well as showing a 'must have' attitude for the Clear Files with anime girls on the covers. But then she can be self-sacrificing, as when she set aside all of her own plans for the day, and decided not only to nurse Mihari back to health, but to attempt to do domestic duties on top of that ! Mahiro was, early on, so fearful of being one-on-one with both Kaede, and her younger sister, Momiji. But when the 'ice was finally broken', Mahiro now says that she loves to be with the two girlfriends. Mahiro even makes friends with two other middle schoolers, girls that are in her class in Middle School, even though Mahiro is a couple of years older than them. Finally, Mahiro's sometimes is at odds with her sister, Mihari, such that they have a spat of misunderstanding between them. But then, love will win out, as Mahiro not only is now not afraid to show her deepest emotions to Mihari, such as crying on her lap, but she loves her sister ( *Philia Love* ). Although still a little suspicious of Mihari due to her sudden and unorthodox transformation from male to female, yet she is totally loyal to her in all aspects of life.

## Mahiro's Story

Mahiro seems to have always had an outlook on life that was like that of a rudderless sailboat. That is to say they never had much of a goal to work towards, and very much just accepted what came their way without much concern or reaction. Throughout childhood and into their early teens, Mahiro seems to have followed 'the line of least resistance' with regard to school, play, friendship, and many other endeavors. This attitude of theirs turned out to be both a curse, and a blessing. Without a sense of direction in life, Mahiro was in a sense cursed with a hopeless and directionless existence, one where they would not want to take any responsibility for themselves or any betterment of their life. However, because of such mindless inability for any significant action on their part, Mahiro was in such a position that Mihari could take control of Mahiro's life without much effort on Mahiro's part, once Mihari saw that Mahiro 'was a goner' in how their life was going.

With gentle perseverance, Mihari begins, covertly at first, changing Mahiro's life for the better, even if this means reworking their body, mind, and spirit so as to align correctly with Mahiro's apparent female Gender Identity. With this 'fork in the road', and the fact that the female road was chosen for Mahiro, this is how Mahiro's life was reset for the better, before it would certainly have ended in their own suicide, as so often happens with transgender teens. As time goes by, and Mahiro has had time to experience what life is like as a cute teenage girl, she also has the ability to compare their former life perceived as a guy, to that of her present life as a girl. Slowly, Mahiro has come to understand that her current life, despite some throwbacks to a male way of life, is really better all around. In Chapter 33, Mahiro is giving out chocolates on St. Valentine's Day during the homeroom time, and at other times, at school. She traded chocolates at first with only the other girls. After she was done, she makes the following remark to herself in her own mind, showing that she, indeed, views herself as a girl, and has, more or less, accepted herself as an authentic girl---

"Toward the end of the school day, Mahiro has a pile of chocolates on her desk and remarks to herself, "What a haul !!!" She further thinks to herself that this holiday is great, and that *she is glad that she is a girl,* as a typical boy would not fare so well in the chocolate exchanges. ( lit; 'This could not have happened [with me] as a guy, huh .....?' )"

Not to mention the incredibly cute and fun things that teenage girls can do or get away with, like buying and wearing a bikini swimsuit to the beach ! Or eating parfaits without a shred of guilt ! This is what makes Mahiro's story worth telling, albeit with a good dose of humor, and with the love and concern that Mihari had for her sibling, and a 'little help from [her] friends]', as the song goes !

Mahiro's Story / Is Mahrio a Trans-Girl ?
A question that seems to keep coming up in discussions about the Main Character, Mahiro Oyama, is whether or not they are a male-to-female transgender teenager, or on the other hand, merely a cross-dressing teenage male ? As one reads the story line as presented by the mangaka, Nekotoufu, one can discover, ponder and review evidence, and then come to their own conclusion about this aspect of Mahiro's mind, heart, and soul. Below is compelling evidence to consider so that one can come to a reasonable and agreeable conclusion that answers this question to adequate satisfaction.

**FIRST**>>>>>>>First and foremost, the title of a manga or anime will often be descriptive of what the overall theme of the manga or anime is going to be, or how the story is going to play out, or a clue to what is going to happen to the Main Characters. A careful consideration of this manga's title will give evidence as to what happens to the Main Character, Mahiro Oyama. This doujinshi and manga created by Nekotoufu is titled, *Onii-chan wa Oshimai.* When written in Japanese Kanji script, "*Oshimai* " translated into English literally means "the end" , or "it's over", or "done for", or "gone away", or "disappeared", or similar. "*Onii-chan*" translates as "older brother". So the most accurate translation from Japanese Kanji to English is "*My Older Brother is Done For (*Lit. Alt. *Comes to Their End)*". But if the title is read in Japanese Hiragana script, we can look at the "Oshimai" part and read it as "[O] Shimai", which literally means "Sisters" . Therefore a translation from Japanese Hiragana to English would be, paraphrased, "*My Older Brother is Actually My Sister*".

If the story line about the Main Character, Mahiro Oyama, born perceived as a male, was to be told with the understanding that they are merely a cross-dressing teenage male, shouldn't the title be something like, "*My Older Brother is a Normal Teenage Boy Who Occasionally Likes to Cross-dress*" ??? But that is not what the title of this manga is. The title, "*Onii-chan wa Oshimai"* in English means that the Older Brother, Mahiro, comes to their end, or is done for. Mahiro is not killed in the manga story, so what about Mahiro died, or comes to an end, or is done for ? Reasoning on the evidence of what the title of the manga means, comparing it with how the story is told by the mangaka, tells one that Mahiro, as a debased, degraded male, presenting with a male gender expression, is what comes to an end. Mahiro continues on with their life as an attractive teenage female, the earmark of a male-to-female transgender teenager.

Although Mahrio and a few of the other characters continue to refer to Mahiro with male pronouns and other male descriptors, that just shows the inability of family and friends to quickly adapt to changing circumstances, that is, Mahiro becoming a atomically correct female in a relative short period of time. So much for the deficiencies of human nature with regard to identification and social circumstances, and that interpersonal communication is sometimes 'set in stone', and hard to reboot or upgrade. Essentially, the outcome for Mahiro is told right there in the title, that they 'died' or 'was done for' regarding their male gender expressions, and that they eventually transitioned to that of their correct gender identity of a girl, presenting as a trans-girl, the 'Older Sister'.

**SECOND**>>>>>>>In Chapter 1, it is reveled that Mahiro was being given a drug, albeit without their knowledge, that changed them from a perceived degenerate male, to that of an atomically correct girl. The change was relatively rapid, but as the story continues, must be given at regular intervals to keep Mahiro's body conformed to that of a female. Going off the drug, or having something negate it's effects, as in Chapters 17,18 & 50 would cause Mahrio to revert back to being physically a male, complete with a male sex organ. This means that at any time Mahiro could refuse to ingest the drug, even to the point of going on hunger strikes, if they were truly wishing to remain a perceived male. But the story line actually shows that Mahiro does not oppose the taking of the drug, and in fact, considers it as needed and necessary. This is shown by this exchange between Mihari and Mahiro, taken from Chapter 1---

" And if we stop the medicine, you will go back to your old self, at least I think so ! ", intones Miahri.

" You think so ? ", repeats Mahiro.

" Why not take advantage of the situation ", adds Mirahi, " and *enjoy a girl's way of life ??? "*

" A girl's way . . . . . " muses Mahiro, " If you have gone this far . . . . **I guess I might as well try and enjoy it . . . .**

A person wishing to continue to present as a boy, and only occasionally cross-dress in girl's clothes, would not consent to the above reasoning. They would insist that they stay a male, and this by *rejecting the drug*, but keeping their female clothes. As far as the drug itself, the Mangaka, in Special 22.5, in the comment section, states that *the drug was especially formulated to be a TS drug (Transgender drug {lit. Transsexual drug}), for the purpose of changing one's sexual appearance*. Consider what actually happens to Mahiro, even though they make numerous comments over a period of time about 'my manly self', is that they consent to take the drug, *fully knowing that they will continue physically as a female*. And Mahiro does more than just 'consent'. In Chapter 50, the drug becomes ineffective when Mahiro is in the school's swimming pool. By the time Mahiro is back at home that afternoon, she bursts into the front room and demands that Mihari administer a booster shot of the drug to her pronto, like right now! No ifs, ands, or buts! Consequently, this is a major earmark of many male-to-female transgender persons, the taking of gender drugs to facilitate their presentation of their correct gender. And this earmark, this kind of personal consent, this demanding of the drug, is the criteria of a transgender person, proving that this is who Mahiro obviously is.

**THIRD**>>>>>>>In Chapter 2, Mahiro is told to bathe and dress in clean clothes, something that they as a debased perceived male, have not done very often, preferring to stay in their room wearing the same male clothes for days on end, and not bathing more often than about once a week ( "You smell like an unwashed dog!" {Chapter 2} ). Mihari lays down the house rules to Mahiro---she will bathe once a day, and change into clean clothes each day! In the beginning, Mihari would select the clothes for Mahiro to wear on a daily basis ( see Chapter 2 ). Over time, by about Chapter 11, the story line shows that Mahiro begins to select the clothes that they will wear each day, all by themselves. Mihari buys the clothes for her, but consistently, Mahiro selects female fashion from her growing female clothing wardrobe, even when she is at home, or going out in public by herself.

If Mahiro were only a cross-dressing boy, this dressing and going out in female clothes day in and day out would not be happening. As a cross-dresser, they would wear male clothes at home and for going out in public, with them only occasionally wearing female clothes, maybe a couple/three times a month, as a fetish or for sexual gratification. But the observation of what Mahiro wears over time, as told by the story, is the complete opposite of that of a cross-dressing boy. Mahiro *never goes back to wearing boy clothes*, not at home, not by wearing the boy's school uniform, not for casual wear, ***not ever*** !!! By Chapter 20, of her own free will and choice, Mahiro selects and consents to wear the female school uniform for her first day returning to school. This consistency of wearing the female school uniform every school day, selecting girl's clothes of their own free will, all of the time, is another earmark of a male-to-female transgender teenager.

**FOURTH**>>>>>>>After her transformation to that of an atomically correct girl, it takes some time for Mahiro to develop social and interpersonal skills. What with them being a male Hikko NEET, shut up in their room for over two years, this is to be expected. Slowly, Mahiro is introduced to other girls on a social basis, as shown in Chapter 7 (Kaede), and Chapter 11 (Momiji). Later, in Chapter 20, when Mahiro reenters middle school, she is introduced and offered friendship and intimate companionship by two other girls (Asahi and Miyo-chan). According to the story line, there is a social division in the school between many of the boys, and many of the girls. Both groups keep to themselves, there own circle of friends, with little or no overlap.

If Mahiro entered the school as a cross-dressing boy, they would wear the male school uniform, just like all the other boys. Only occasionally, would Mahiro wear the female school uniform as a cross-dressed student. Given the social divide at school, cross-dressing Mahiro would only have boys as friends, and be part of the social circle of boys that is in the homeroom. But that is *not what we see as presented by the story line !!!* Mahiro is enrolled in middle school as a girl (Chapters 21 & 22), and is immediately accepted into the social circle of girls in the homeroom, something that a cross-dressed boy could never do ! If fact, in several chapters, Mahiro has to be protected by the other girls in the girl's social circle, this from the questionable antics of the boys (Chapters 22 & 33). Mahiro is accepted by the four friends (Momiji, Asahi, Miyo-chan, and Nayuta) **as an authentic girl,** not a boy !

In the middle school where Mahiro attends, inside the social circle of the four girls, plus Kaede, Mahiro is offered and seems to except a shipping that can never be done by a boy---Mahiro is offered a Shoujo Ai and/or a Yuri shipping with Momiji, and possibly with Miyo-chan. By it's very definition, a Yuri shipping has to be between two girls, or between a girl and a trans-girl.

Additional evidence that in school Mahiro is seen as an authentic girl, and not as a cross-dressing boy can been deduced from Chapter 37. There, Mahiro is being reprimanded by a well-respected teacher ( Sensei Mari ) for allegedly wearing makeup to school, something forbidden by school policy. During the conversation, Sensei Mari refers to Mahiro ***as an authentic girl***, not a boy. This means that the teachers, the school officials, and entire school administration, not only *enrolled Mahrio as a girl*, but recognizes her as an *authentic girl*. And by proper and reasonable implication, if the school district has designated Mahiro as a girl, then it is very likely that the Prefecture Government that Mahiro and Mihari live under also recognizes Mahiro as a girl.

And finally, in Chapter 41, Mahiro declares that she does not want to be seen by a male doctor during the physical exam day at school. A boy who cross-dresses would not mind being seen by another male, but a trans girl would object to doing so, just like Mahiro objected to the male doctor. (Mahiro was actually seen by Azuma

**FIFTH**>>>>>>The following two pictures were drawn by the managaka and commented upon by the English translator of *My Brother is Done For,*. The two pictures were placed at the end of Chapter 36, as Nekotoufu, as well as the English translator, frequently do, as Omake (Extra) content to be considered along with the chapter's story. Notice these honest comments about the Main Character by the English translator, one character who they would know well given their extensive translation expertise, Mahiro Oyama---

The English translator comments that Mahiro views themselves *as a female, as an authentic girl* ! This possibly means that Mahrio has done a 'coming out' to themselves as their correct gender presentation. This is many times a first step for male-to-female transgender people to do to begin their transition. Notice how far Mahiro has, according to the viewpoint of the English translator, progressed in her transition---84%. Not bad !

Reasoning on the obvious evidence, one can plainly see, by Mahiro's consistent choice of clothing styles, by her social interactions, her being acceptance in girl-only social circles, by her being enrolled in middle school as a girl, by her developing a Yuri shipping with another girl, and finally by her doing a 'coming out' to themselves as to their correct gender, Mahrio ***is obviously a trans-girl !!!*** Mahiro, despite being a transgender teenager, is an *authentic girl* that can be part of the social fabric at school, at other social activities, and is legally recognized as such by the school district and the prefecture, too ! And now Mahiro, in her own mind, heart, and soul, for the most part, views herself as a girl.

\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_

Enough evidence exists in the story line of *My Brother is Done For* to correctly deduce that Mahiro is a male-to-female transgender teenager. Because of this, this is why Mahiro's story needs to be told, in manga fashion, and on this Wiki, for the benefit and encouragement of other male-to-female transgender people IRL. The Founder, Admin, and B'crat of this Wiki believes that enough empirical evidence shows that Mahiro is definitely a trans-girl, and all of this Wiki has been, and will continue to be written, from that factual point of view.

## Trivia

In the Japanese language, the first name 'Mahiro' can be either feminine or masculine. The first name 'Mahiro' means the deep blue - green waters of the open sea.
