That Hot Pot Conductor (鍋奉行, Nabebuyou) is the spirit of a magistrate who haunts a Nabe Pot.
He looks like a Samurai.
He's the spirit of a corrupt magistrate that wanted to haunt a Nabe Pot to sew the seeds of conflict. Ageha found that Nabe Pot at her storehouse and brought it to Rinne. He is meant to judge what ingredients can be added in the pot and how long until they are cooked, but instead steals all the eggs for himself and leave none for anyone. Tsubasa disillusioned subdued him.
