Bikou

Bikou is a supporting character in High School DxD. He's a Monkey Youkai and the current Monkey King, as well as a descendant of the legendary Sun Wukong (the Great Sage Equaling Heaven).

He starts as a member of the Vali Team within the Khaos Brigade (later shifting affiliations to become part of Team DxD). Bikou has a carefree, playful, and battle-loving personality with little regard for formalities—he lives freely and enjoys fights, much like his ancestor but without aspiring to enlightenment.

In combat, he wields abilities like Senjutsu and Youjutsu, and uses an extendable/retractable staff (similar to the Ruyi Jingu Bang) along with a golden cloud he can ride. He appears mainly from Season 2 (High School DxD New) onward in the anime.
