D-i-v-a
It's sorta been confirmed, Episode 48 when Nathan was talking Amshel, he implies that he's Saya and Diva's
Mother's Chevalier. therefor neither of they're blood should harm him. Resulting in him still being alive.
ahh ok, thank you. Thats still weird that he had saya "kill" him, because diva dies, and then he ends up being alive anyway..
