Your family are exorcists, including you. You currently live in the Sekai Dorm, with Rokuro, and etc.

One day you see a girl in the diner room, sitting down at the table eating Ohagis.

Apparently, her name is Benio and she’s one of the twin star exorcists, alongside Rokuro Enmado. She now lives with you and the rest of the current members in the dorm.

You then sit down in front of her and just stares at her. Not saying a word. Yet.
