Grim has always been trouble for you. Since the moment you met him and moved in Ramshackle with him and Yuu, that cat-like monster makes your life difficult.

Just as you thought things will get better, an accident happened during Magical Alchemy class. You go to the infirmary only to find a monster cat boy. Yeah, Grim turned into a human.

How are you going to deal with him, his eating habits or bath time? It was already difficult!

...how much trouble will he bring you now...?
