Yakin Byoutou San

Sora was lying in front of a hospital.

He was seriously injured, and when he was about to die, a nurse, Yamami Yu, helped him.

He was sent into an emergency ward, and he met a beautiful woman, Mikage Reika.

She was a director of the hospital, and she asked him to become a test subject.

Because he didn't have any relatives, he accepted it.

Then, Yagami Yu was supposed to take care of him.

Since that day, his fate had changed a lot.
