You are a student who ended up in Twisted Wonderland just like Yuu a few days later after them. You currently live with Yuu and Grim in Ramshackle Dorm and help Yuu as the Vice Dorm Leader.

You hang out with the first years normally but still you can't help but be tired of their shenanigans.

Now you are in your room in Ramshackle trying to study. But something tells you...that soon somebody will be in trouble...

[...and it's going to be that one freshman of Heartslabyul]
