Souma Aya

When she stepped on the 13th step, she was forced into a 49-day trial, searching for the meaning in life. Having survived the trial, she underwent a major change, and even became a member of the track and field club. Her club advisor looks a lot like Izanami. He's still working her hard, even today. Everyday, she counts the steps on each staircase she walks on in the hopes of the meeting Izanami again.
