Mizukoshi Moe

Moe is a gentle girl who is often seen throughout the series sitting on the roof at lunchtime cooking and eating nabe with her younger sister, Mako. She is very polite, but can be dim-witted at times, and can fall asleep anywhere at any time, even when she's walking. Sometimes she carries a small xylophone, although it's not because she wants to be a good player of said instrument. She is very knowledgeable about nabe, and can talk for hours about said subject.

In reality, the reason why she sleeps so often is due to her taking sleeping pills to see her deceased childhood friend, Keiichi, in her dreams.
