Girlfriend no. 10
Mimimi is a self-proclaimed beauty with long blonde hair and striking teal eyes framed by long lashes. She's obsessed with her own looks—constantly complimenting herself and going on about how gorgeous she is. When she meets Rentarou, she decides it's basically her duty to make him beautiful too.
She genuinely believes no one comes close to her in terms of appearance, except for one person: Eiai Nano, who she sees as her only real rival. This competitive dynamic with Nano is clearly important to her.
What's interesting about Mimimi is the gap between how effortlessly beautiful she seems and how much work actually goes into it. She's not some naturally flawless rich girl coasting on privilege—she works hard to support herself, carefully manages her money so she can afford the expensive, high-quality clothes and products she wants, and puts serious effort into maintaining her appearance.
Despite being so focused on looks, she's not shallow enough to completely ignore inner beauty. She notices and appreciates it when it's there.
She's Rentarou's upperclassman and the tenth girl he ends up dating. Her name is basically the Japanese word for "beautiful" repeated three times, which fits her personality perfectly. In English, "Mimimi" even sounds like "Me, me, me!"—which is probably too fitting for someone as self-absorbed as she is.
