Yukihito

The temple assistant, his duties are to assist the priest and Miko in readying the weapon that will defeat the Orochi. It is unclear if he is a hired employee, relative of the Ogami family, or a junior priest-in-training (the last is unlikely, as he is never seen wearing Shinto clerical robes). He is also Souma's best friend and confidant, though the latter is shown more in the manga than the anime. (Source: Wikipedia)
