The Hishaku
Ten criminal sorcerers marked by flame, able to teleport through fire — responsible for the murder of Kunishige Rokuhira.

The Hishaku is a group of ten elite criminal sorcerers, all identifiable by a flame-shaped tattoo. Their shared mastery of fire sorcery lets them teleport at will, making them particularly difficult to track down.
It is this group that assassinated Kunishige Rokuhira and stole six of the seven Enchanted Blades, on the orders of its leader, Yura. This act is the origin of Chihiro's quest for revenge.
Each member of the Hishaku possesses their own sorcery and a formidable fighting style, making the group one of the most dangerous adversaries in the story.
