As revealed in episode five, a hermaphrodite possessing qualities of both an angel and an immortal, which, according to him, makes him a "god." He is only truly interested in immortals and angels. He seems to have no concept of human morals but instead, has a sadistic sense of amusement and beauty. Eipos seems to have some mysterious interest in Rin, to the point that he hires mortal killers to target her. In episode three, he reveals that he is after Rin's time spore. Apparently, time spores contain the immortals memories and Eipos enjoys consuming them. It is also revealed that he has the ability to instantly remove the spores from (thus, killing) both immortals and angels. Anyone else wishing to kill an immortal must do so by physically digging through their victims flesh for the time spores. In episode six, he is revealed to be the Guardian of Yggdrasil and has chosen Rin to be his bride. Guardians are suppose to switch every once in a (long) while, but Eipos wishes to become a permanent guardian by sacrificing Rin to Yggdrasil.
