As a human, I tried my best to protect my comrades but I was helpless against vampires. Then, I tried to avenge them, but again, helpless against Ferid, who found me and turned me into this with the blood of Saito (2nd progenitor) in secret. I'm a noble vampire and everyone else thinks l was bitten by my comrade Ferid and the 13th progenitor, but I'm the 7th. I don't need to kill cattle like you, but that doesn't mean I won't bite you.
I'm not after anything in particular myself.
