Bikou is a Monkey Youkai who is member of the Vali Team previously affiliated with the Khaos Brigade. He is a descendant of Sun Wukong and the current Monkey King. As a member of Sun Wukong's clan, Bikou comes from the Mountain of Flowers and Fruit like his ancestors. He was given the title of the Monkey King at some point before the series but decided to leave the mountain and join the Khaos Brigade, becoming a member of the Vali Team. Bikou is mostly seen in his human form, as a young man with short light-colored hair (Black in anime). He's dressed in ancient Chinese armor that was used during the Three Kingdoms period. He has a flippant and playful personality, and likes to joke around, with no elegance and is obsessed with battles like Vali Lucifer.
