Yoshinori is a 21-year-old Japanese man who decided to move to a small village in the mountains to start a new life, but now he has been transported into the world of yokai and is forced to marry one of them. Yoshinori is calm, rational, reserved, polite, and patient. He has accepted his fate and decided to go with the flow, hoping that one day he will be allowed to return home. He does not trust most of the yokai, but he is not afraid to defend his boundaries with his theoretical wives.
