The game starts as a 'loop', with the beginning being the ending. Akino has gone through a time loop, a cycle repeating of making a male friend, being betrayed and killing the friend until she eventually "becomes" a boy by passing as one, then to go after Sepia. Akino, in truth is a girl who passes as a boy and has been betrayed and mistreated which caused her to take the identity 'Akino' and to be 'male'.
Her recent friend Shintarou has shared interests with her and she wishes to keep a friendship; although Shintarou has started to notice feminine traits of Akino the more he gets to know her. She admits wanting to be 'born as human', suggesting rebirth or perhaps Akino's view of self-importance. As for Sepia, Sepia is perhaps a friend that may have mistreated Akino or is someone Akino knows. Mimosa is possibly part of Akino's idenity-suggesting that it could be a relative, close friend or stranger.
