“Your very heart is beautiful...! I am sorry...in the past, I was once humilated when an acquaintance refused my request for friendship...it petrified me to think you, too, would refuse my confession, which is why I...I ignored. No, I did not want to hear your reply. Aijou-kun, I truly like you. Please...go out with me.”Mimimi is very haughty and narcissistic, constantly complimenting herself and talking about her beauty. She is obsessed with beauty to the point that she takes it upon herself to make Rentarou beautiful as well once she meets him. While believing herself to be almost unparalleled in her looks, she is very competitive to the rival she admits surpasses her, Nano Eiai. Despite her appearance of a naturally beautiful rich girl, Mimimi actually works incredibly hard to provide for herself and keep herself beautiful. She works for herself to earn money, is frugal where appropriate so she can afford expensive, gorgeous clothing, and puts significant effort into her appearance. Though she puts a lot of value on outward appearances, Mimimi also recognizes inner beauty when she sees it.
