Birthdate: 23 August (11 ep.) A 2nd Lieutenant Juvenile officer and son of a General of the GHQ. Nicknamed "Kill 'Em All Daryl", he is a cruel and sadistic man who enjoys causing pain to others and due to having mysophobia, he hates being touched by others believing they are infected. His Void is a weapon called "Kaleidoscope", which is able to create a myriad of barriers to deflect attacks.
Later on the show, he becomes more humane after he kills his father who despises him and disguises himself at the school where he bumps into Tsugumi and takes a liking to her; this becomes more apparent when he doesn't shoot her and tells her to move.
