Akane, Aoi

Aoi Akane is a first year student at Kamome Academy's High School Division and Yashiro's best friend.

She is a cute, petite girl with indigo hair and eyes. She keeps her hair tied up into two circle sections behind her head. Her bangs are loosely parted to frame her face, and there are two thin, wavy locks of hair that fall past her chest.

[Spoiler] She is currently deceased but her biggest regret as she was trapped in the Far Shore was that she never said "I like you too" to Akane up until the end. [/Spoiler]
