Kintaro is a demon in the series.
Kintaro is a folk hero who, as a child raised by a mountain hag upon Mt. Ashigara, had superhuman strength. He was friendly with all the animals as he grew up and would eventually catch Shouten-Douji. He would eventually become a follower of Minamoto no Yorimitsu and change his name to Sakata no Kintoki. There are several versions of the myth of how he was born. One had his mother become pregnant thanks to a clap of thunder caused by a dragon upon Mt. Ashigara.
His many mythical feats include sumo wrestling bears, fighting demons, and felling trees for woodcutters. When he became a follower of Yorimitsu he would learn martial arts. He is based on a real man named Sakata Kintoki who was a retainer to the samurai Yorimitsu.
