Cielo is an Embryon member that specializes in the use of a submachine gun. He is also the last of the Embryon tribe members to awaken, but also undergoes the greatest change. His behaviour changes drastically from that of calm respectable member to that of a fun-loving guy with a rebellious streak; even his accent and the manner of his speech changes. Cielo's Asura form, Dyaus, is the ancient Vedic god of the sky, he is the husband of Prithivi and the father of Agni. Dyaus is an unusually weak character, but has high evasion of attacks and tendency for critical hits.
