داریل یان

A Second 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.

[Spoiler: 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.]
