Status: Regional Lord Favorite food: Rice and Jasmine tea Familiar: Guest A boy who became Guest's master. In combat, he fights flexibly by freezing and thawing water at will. In close quarters, he uses ancient martial arts to overcome strength with softness. Strong at both long and short range. Though insincere, he is good at maneuvering; whenever trouble arises, he pushes it onto Van and slips away. He has good manners but his ability to handle daily chores is catastrophic. He is friendly with his Kansai charm, but his elusive personality creates a wall, and he is always alone. His parents are deceased. He lost them at age 12 and became the lord. Forced into a position of protecting his territory from a young age, he harbors inner loneliness. Though a regional lord of the East, he leaves the administration to a trusted vassal from a branch family, "Tou Ran," while enjoying academy life. Despite his casual attitude, he is gentle in his treatment of Guest. Has a mole near his mouth. He is very precise with money calculations.

Constantly snaps at Roa's sarcasm but considers him a reliable partner. From a common family in the West. Before coming to the academy, he lived with his alcoholic father; his mother was absent. He spent his days fighting at home and on the streets, but his high potential—blowing away opponents with self-taught wind magic without learning the basics—reached the academy, leading to his enrollment.
