Кян Харука

President of the Track and field club and childhood best friend of Akira. They were extremely close in the past​ but almost stopped communicating after her trauma. Haruka feels that Akira hides some deep problems and it worries her a lot.

She is a supportive and caring person who cares deeply for her friends, including Akira, and is quick to defend her friend. She can be adamant about things that she truly believes in, and is persistent in getting what she wants.
