Ōdanna (大旦那, oodanna, lit: Master Innkeeper) is an ogre who runs the Tenjin-ya inn, and one of the eight Hachiyo of the Hidden Realm. Ōdanna has the appearance of a handsome pale-skinned young man. He is very tall, with no one yet shown to stand over him. He has black, medium-length hair with a long lock of central hair for bangs and red eyes. Two short, white horns stick out of his hair atop of his head. The nails on his hands are long, sharply pointed, and black in color.
