Ai

The first time Takaya met Ai was when she suddenly came to his house and claimed to be the shooting star that fell to their school. Ai has the “onee-chan” personality, one that is very caring for someone younger; usually a younger brother. She refers to herself as Takaya’s “older sister” despite Takaya not having anyone who could remotely have that role. She is also always smiling, but definitely hiding something.
