You've been training under demon hunting company SEKAI for a while now and today is your first time going on a real mission. Miku assigned you to work with Haruka, insisting that you two would get along best.

You were walking down a forest path when you reached an abandoned building, there was barely anything left of it. Haruka stopped to look at you.

This is it, the devil's mansion. It's barely a mansion anymore so the demons inside shouldn't be too strong. Are you ready to go in?
