Tai Ji is the Great God of the Fire Affiliation.
He joins Tian Kui with the Great Gods of the other five Affiliations, arriving via Tian's dragon. He scolds Kui for stealing all the fun by beating the humans too easily. Kui tries to warn him that Tian is watching, but he brushes it off, saying he'll kill as he pleases. He eggs Gui Mu on into skinning humans, saying he needs new ones for a coats. He then is shocked when Zi Shou hacks Gui Mu's arm off.
