A counsellor who has an insane obsession with eyes, especially Ray's blank, blue ones. Due to being born without a right eye, he was bullied for most of his childhood. His missing eye also caused fights between his parents until they divorced and his mother committed suicide. From there, Danny began to find blank, dead eyes like his mother's beautiful, becoming a counsellor to search for eyes that could satisfy him.
Prior to the series, he was a counsellor for prisoners and met Gray, who offered him the chance to become a floor master. Believing it could satisfy him, Danny took on the offer and subsequently used his authority to bring Ray into Gray's experiment and make her the floor master of B1, hoping that he could live close to her eyes. He is ultimately killed by Gray in his pursuit for Ray.
