Koshian

Koshian (越庵 Koshian) is the Buddhist priest and caretaker of the Tariki Hongan temple where Keiichi and the Goddesses reside. After witnessing Belldandy's "spiritual enlightenment", Koshian left on a pilgrimage to seek his own enlightenment, leaving his temple and house in the care of Keiichi and Belldandy. He returns in the anime at one point after traveling for eleven months, but soon gets caught up in a fight and leaves again. After returning a second time, he appears briefly, kicking Belldandy (who at that time has an evil mark on her head) and Keiichi out; but when Belldandy gets her goddess licences back, she and Keiichi return to the temple. He is last seen watching Belldandy's lighting burst, calling it the "Great Dragon"; then he disappears for the rest of the series.
