Furthermore, she can even speak, and is even knowledgeable of the other world. The cheat-like Misha used transformation magic and turned into a beastkin (Nekomimi). Together with the Nekomimi young girl (sometime she is in black cat form), this is the story of our slow and leisurely life in the other world.
