Yakunara Mug Cup mo S2 - Episode 4 - Mika Dries Off Mad Demon

Mad Demon is that clay penguin with a flower hat. He recalled how Mika cared for him and shaped him.

Mad Demon started out as a lump of special clay. He wanted the talented Touko to make him into something beautiful. The thought of the flighty Mika creating a strange creature out of him dismayed him. Mika wasn't so silly, and Mad Demon came to appreciate her dedication to him. Especially how she visited him to make sure he always had a crown of flowers.
