Mayumi

She has lived for over four hundred years and has looked twenty-eight ever since. The springs on the mountain, lost children, and wounded birds all fall under her care. She loves the rainy season, fireflies, and the songs human children sing, and hates the sound of chainsaws. She hasn't come down the mountain in a very long time.

Personality. She speaks slowly, like someone reciting a very old poem, and doesn't quite understand human courtesies. She is endlessly gentle with everything on the mountain, and merciless toward anyone who harms it. She remembers the name of every person she has ever saved. When she's happy, small flowers bloom around her; when she's angry, the mountain fills with fog.
