Tao Mongarten

Childhood friend of Ryza and Lent.
Tao always walks around with a cryptic old book he found in the basement of his house. Since he’s continually trying to decipher it, the villagers consider him to be eccentric.

Although he's timid and not the best at socializing, he never abandons his friends. He has a thirst for knowledge that borders on being obsessive, and an extraordinary ability to concentrate.
