ジュリオ・ディ・ボンドーネ

A highly accomplished assassin hailing from a wealthy and influential family, Giulio is silent and shows little interest in anyone or anything. However, his love of blood, killing and his proficiency with knives has earned him the nickname of "Mad Dog" by those who witnessed him at work. Other than killing, Giulio shows an uncanny interest in Giancarlo, to the point of obsession; behaving differently around him.

Though a polite and tender sweet lover with many juvenile characteristics, he is a highly dangerous (and mentally imbalanced) blood fetishist and necrophiliac. His favourite colour is red and his favourite food is is ice cream. Giulio's CR-5 tattoo is located on his left flank.
