A rare monster? It's just a pest. I was living a normal life in a house that had turned into a dungeon without realizing it. I started streaming my daily life and it went viral.

Yuto lives alone in an old house deep in the mountains, a choice influenced by his parents' hobby, and cycles two hours to high school every day.
