Kamitsuki ends up having to move from Chiba Prefecture to Gunma Prefecture. He decides to do a little bit of research about Gunma on his way over, and everything he finds out is terrifying! For example, “The world’s only remaining unexplored area,” and “Make sure you take all your best equipment.” What kind of place is Gunma? What kinds of things are going to happen to him while he’s there? The Gunma-born author brings you the real truth about Gunma in this series.
