The Girl of Knowledge and Shade

Patchouli Knowledge

Her weak constitution makes her poor at physical combat, but she makes up for for that with her various and powerful magical attacks. Patchouli's ribbon is not a holy charm, but rather an accessory that boosts magic power.

As a genuine witch, she possesses terrifying sorcerous powers. However, due to her natural asthma, she has difficulty reciting her incantations to the end. She also seems to have a vitamin A deficiency.

Maybe her windowless library room is dusty. No, obviously, it's very dusty. But with all the time she spends near her books, she feels that they're a part of her and cannot stand to be separated from them. She's lived this way for a hundred years or so.
