Kou Tenka is a disciple at Konron, and Kou Hiko's second son. One of the Juunisen, Seikyo Dotoku Shinkun, discovered and recruited him as a doushi. He has his father's upstanding spirit and fighting skills, but his mother's black hair. He uses the inflection "-sa" at the end of a sentence, and is always smoking a cigarette. He is master of the lightsaber like paopei, "Bakuya no Hoken," and later receives a fire-emitting, boomerang paopei called "Karyuhyo," and the tiny lightsabers "Sanshintei." After the sennin battle at the Kingou he received his master's "Bakuya no Hoken 2," which has a blade on either side of the handle. Because of his absolute self confidence in close combat, and too much of a warrior's spirit, he extremely hates to lose. He has a rough attitude and would jump to conclusions.
