Mai is a very cheerful and temperamental girl. She tends to also be somewhat of an airhead and admires any kind of beauty or attractiveness, which sometimes comes across as being vain. She also at times compares attractive boys who flirt with her or acknowledge her beauty to Andy, acknowledging their attractiveness but ending with a comment saying they're 'not as cute as Andy'. Like many girls, she has dreams of getting married to her Prince Charming — she found her own Prince in Andy Bogard, and self-proclaimed herself his fiancé, which at times has creeped out Andy himself. Within the Fatal Fury series, he mostly tries to ignore her advances as he views her like a younger sister but has a hard time adequately returning platonic affections due to her persistence.
