One day, a mother Marisa comes out into the forest. She announces that it's a sunny day, and her children follow: A normal Marisa koyukkuri (who is the eldest sister) and afterwards... another Marisa. But this one is special: it has a shell instead of a hat. There's then a flashback to when the shelled Marisa was born; a Patchouli explains that it's a rare breed, and that the shell it has is waterproof. The elder Marisa is ecstatic that her sister is special, and so is the mother. Mother Marisa cries over the death of her special child, and asks why it had to happen.
