Due to a mistake made by the G.o.ddess, my house cat Misha is reincarnated as the strongest character instead of me. Furthermore, she can even speak, and is even knowledgable of the other world.Misha with cheat-like power uses a transformation magic, and transform 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 leisure life in the other world.
