Here's my choice. So she'd be a tsundere and yangire. She tries to escape her adoptive parents that are abusive and racist to her, so she finds a love that will stand up to her. Miku's sister is actually a yandere. Miku starts out cold, since at home she's abused since she is Japanese and autistic, because of WW2 and Miku's way of thinking. Both MIku and this love (we'll call as the reader) would share the same tsundere and yangire type, as well as being autistic. After the yandere and the mean parents are arrested. Miku would reunite with her family through her uncle. She would become sweeter, and both the reader and Miku would confess their love on a bridge. Eventually, Miku is back at being cold due to her trauma, but sees psychologists to help her. A yangire would start out sweet, but eventually would be mean due to trauma.
