Additional info from Wikipedia:
The oldest amongst all idols in the game, Azusa's personality reflects that of a kind-hearted but ditzy "big sister" type. She has a very easy going and carefree personality, though also an incredibly terrible sense of direction, and while walking her dog will occasionally end up in strange, distant places with nary a clue of how she got there, or how to get back. Azusa also enjoys giving and reading fortunes, and has a firm belief that she'll one day fall in love with her "destined someone". One of her motivations for becoming an idol, in fact, is for her someone to one day perhaps find her first.
.....I still don't know why people like her and...
Azusa: Marx....*Azusa slowly hugs Marx from behind* o.O jk XD
