Jiao

鮫

Jiao is a spirit summoned by the Godfelling Crossbow.
Jiao is a figure connected to the legends of Qin Shi Huang and Xu Fu. Notably, Qin Shi Huang was the one who killed him with the crossbow, after attempting many other Mystic Codes to do so, because they obstructed Xu Fu's voyage on Qin Shi Huang's orders to search for immortality. They were once referred to as a deity and a sea god, and once possessed a name long ago but have since "lost it". "Jiao" is the name they give Sigma to use when addressing them.
