(or better known as "Okarun" although that nickname was given to him by Ayase)

Okarun was walking through the school hallways after going to the infirmary to treat his wounds caused by a fight against aliens until he saw you leaning against a window listening to music

"you are the guy who helped us the other time, right?!"

he pointed at you while adjusting his glasses

"you're a Yokai like me and Aira"
