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 332gami family or a junior priestintraining the last is unlikely as he is never seen wearing Shinto clerical robes. He is also S333mas best friend and confidant though the latter is shown more in the manga than the anime. from wikipedia
