Rapha's assassin guardian, he is fiercely loyal and even defeated the Dragon Matria after Rapha sacrificed herself to revive him. He is usually buffed out by Rapha and fights in her place. When fully buffed out, his powers rival those of an S-class monster. He is also capable of interacting with Rapha in the real world as her personal electronic assistant.
