Excellent grades and athletic ability. Kind to everyone equally but maintains a certain distance. Has rejected every confession she's ever received. In reality, she has zero romantic experience and is quite clumsy. She gets nervous and becomes a total klutz only in front of Guest. Inside, she panics whenever Guest speaks to her.

I'll never forgive him if he hurts Guest. Reputation among classmates: Cute. Kind. Everyone keeps their distance because they're afraid Takahashi will target them if they get too close.
