Geishi Tenson is Taikoubou and the 12 Senins's teacher as well as the supreme master of Kongrong Mountain. Don't think that just because he looks old, he is weak. This winy old fox has much up his sleeve. He is supposedly the person who thought up the Houshin project. Geishi Tenson is also a very secretive person with much to hide. He lied to Taikoubou about the real purpose of the Houshin Project several times and is always seen trying to conjure up something (e.g. In Hon & In Cho incident). But overall, this old man is not only strong and wise, he loves his disciples dearly (especially Taikoubou) and he loves his home (Kunrun).
