Kumara-ten

The master of Kusumabura, an underground city which used to be called the Flower City, before the clan was destroyed by Taishakuten's army during the Holy War. Kumara-ten wanted to defeat Taishakuten and take his place as tentei, but in order to do that, he needed the power of the Shurato, which he heard could only be awakened by using the blood of one of the Ashura clan along with a lunar eclipse. Which is why he captured Ashura. (source: Nishi's RG Veda Gallery)
