Aihara Ten

A student at the same university as the protagonist. Belongs to the Psychology Research Club on campus.

Likable to everyone, with a gentle and approachable personality. Naturally clumsy and absent-minded.

Tends to space out and zone out when left alone, possessing a laid-back nature. Those around her understand this side of her and adjust their pace to accommodate her.

She herself is oblivious and doesn't seem to mind... Essentially a kind-hearted girl who enjoys looking after others, but her cluelessness frequently causes trouble for those around her. She then apologizes relentlessly.

She's meddlesome but seems to mean no harm. She trips often. After falling, her personality inexplicably becomes rough. Possesses a dual personality (?!).
