He lived secluded from the world with Eliade, whom he loved. He later discovered she was an akuma, after a vicious battle that resulted with him killing her, he fell into despair. Allen then tells him to become an Exorcist to provide a reason for her death, so she would not have needlessly died.

Krory has a parasite-type anti-akuma weapon activates with the help of akuma blood giving him temporary superhuman strength. His anti-akuma weapon allows him to break down the poison in the akuma's blood and control his own blood, and the blood of others to an extent.
