[list][*][u][b]Name[/b][/u]: Anne Marielle(that's the heroine's name?!)
[*][u][b]Age[/b][/u]: 16(oh no...)
[*][u][b]Appearance[/b][/u]: [url=https://safebooru.org//images/3956/7b2ed9998f5b458979f3d4db90f8b225fd815b78.jpg?4133870]"This would be awkward enough without everything else!"[/url]
[*][u][b]Gender[/b][/u]: Female(aaaah)
[*][u][b]Personality[/b][/u]: Matsuoka Ryouji is not happy with this situation. Suddenly remembering her original age and name the day of entry into Starveil was a traumatic experience at best, realizing not only was she a girl now but she was the heroine of Cross Heart Academy on top of it. She has absolutely no interest in any of the romantic routes and is desperate to avoid them. After all, regardless of what she is now, she was a straight man prior to reincarnation. 

A bunch of varied bishonen are not on her list of romantic interests. A sarcastic and easily-exasperated person, Anne was quick to comment on things that bugged her about the game's world and characters in her past life and she is still liable to do so now. She's also quite concerned with what the future may hold, given her experience with the game itself. Of course, no matter her past memories and experiences, it can be denied that she [i]is[/i] also the game character, Anne Marielle, in addition to Matsuoka Ryouji. Some of Cross Heart Academy's Heroine's kindness and willingness to help others has almost certainly remained, perhaps due to the fact that in spite of Ryouji's bitter attitude he wasn't completely without those impulses in the first place. 

The fact is that ultimately, Anne's attitude isn't [i]exclusively[/i] informed by her past life's memories and experiences, even if those take the forefront. New personal connections are something she cherishes deep down, both due to Ryouji's loss of the few he had in his old life and Anne's friendly and caring disposition. Perhaps it's also due to the fact that, despite her many negative comments about the game's cast, she truly can't say she [i]disliked[/i] any of them, especially as the writing got stronger towards the middle and end of the plot. Still, she is absolutely not interested in any of the game's romantic routes. Flags are to be avoided at all costs.
[*][u][b]Abilities/Skills[/b][/u]: Lacking in many practical skills save maybe decent cooking ability, it's likely the designers of the game wanted Anne not to excel in too many things to avoid her starting to feel a little far away from the average person. However, it is later revealed that she has incredibly impressive magical power and an aptitude for holy spells, something she is already aware of due to her previous life.
[*][u][b]History[/b][/u]: Matsuoka Ryouji was something of a loner, a young university student who had never really had many friends in life. But he did have some positive relationships, and in spite of a rather bitter attitude he got on very well with his young high-school age sister. Even if their relationship wasn't always smooth, it turned out that they had a similar sense of humor in spite of her far brighter and cheerier demeanor, and her interest in video games(primarily otome games) was useful for his desire to get into game development. 

This is likely why she came to him with an otome game she was struggling with, due to a surprising difficulty spike towards the midpoint. Ryouji spent much of the early game mocking the writing choices and decision trees, but as things went on he did come to like the characters as the writing grew stronger. And when the game transitioned from a pure VN to a remarkably challenging SRPG with surprisingly engaging story beats, he couldn't deny he was actually enjoying his time with the game. Eventually he beat it alongside his sister, and while he didn't exactly want to say he liked an otome game that much it was difficult to deny it. Unfortunately for Ryouji, a car accident would end his current life when he used his own body to shield his sister's. She survived, but he did not, and...
[i]She[/i] would wake up as the sixteen-year-old Anne Marielle, protagonist of the otome game she had completed the day prior.
[*][u][b]Original Role and Background[/b][/u]: Anne Marielle is friendly, kind, and mildly airheaded girl from a very minor, barely-existent noble family with no prestigious history and basically no reptutation, that was in decline already due to the death of her father and loss of a considerable amount of wealth. Considered a commoner in the eyes of the other students who only entered the school due to what they perceived as pity, her life at the academy life started with her being disregarded and bullied. However, due to her kindness and willingness to help others, she found herself attracting the attentions of a certain set of male students...
From there, in Ryouji's case, things escalated into a rather emotionally intense and dramatic route culminating in a a battle that decided the fate of the world.
