Keno is a dusty blond with goldish brown eyes. He's very beautiful and appears at first sight to be a girl, and both Kobungo and Dosetsu fall for him until they find out that he's a guy.
When he first met Sosuke, he attacked him, thinking he was the person who attacked his village. He is feminine in appearance, but is an adept swordsman, and is quite strong. He possesses a sword named Osaza, which his father entrusted to him.
Keno was born with the Wisdom Bead. Two years before the start of the series, Ao destroyed his village, killed his family and carved out his heart, but Keno had refused to die, a fact that fascinated the demon princess Kokonoe. Then, Kokonoe saved him by giving him her heart.
A demon princess. Kokonoe heard Keno call out when he was dying. She gave him her heart and now they are bonded.
Ao is the one who took Keno's heart and thus, Keno seeks revenge on him.
