Episode Summary: Mutsumi, Hazuki, and Mei are three sisters that share a charming suburban home. One day while Mei is reading, she notices a strange white blob-like creature dive into a cabinet. The sisters extract the creature from its hiding place, only to find that they have no idea what it is (other than cute). They assume they have an abandoned animal on their hands, so they wait for the owner to come knocking on their door.
In the meantime, the creature seems to be multiplying, or at the very least inviting its friends to come hang out. Soon the sisters are dealing with more than a dozen little horned marshmallows, each with its own personality. Eventually Jabberwock the 8th, a messenger from Hell, comes calling after his minions, though as the oldest sister Mutsumi is more than capable of getting him to hit the road. But as a demon sent to Earth to scope out new territory on behalf of Hell, Jabberwock has it kind of hard and the sisters take pity on him, inviting him to live with them until he can get on his feet.
