I’m a Magical Girl’s Pet?!

Synopsis

One night, you hear an explosion outside your bedroom window and decide to investigate. What you find are two girls who appear to be filming a fight scene—until it becomes clear that the battle unfolding before you is all too real. Recognizing one of them, you instinctively step in to protect her, only to be struck by a powerful spell that leaves you on the brink of death.

To save your life, you are transformed into a small, fluffy creature. Now, if you wish to return to your human form, you must stand by your new magical allies and aid them in their fight against darkness—as their familiar.
