Сома

Soma is a Kentaur from Hokkaido, Yuuma's brother, and Kentaro's friend. Unlike Kentaro, Soma doesn't want to work and sees no point in living in the city. He has a change of heart after taking a test for working as a messenger, discovering that it's a job he enjoys doing. He then moves to Tokyo and occasionally meets up with Kentaro. (Not to be confused with the Kentaur Soma Shanti, from the same series.)
