Specificly, from Melty Blood Re.ACT a Japanese PC fighting game..
.....
Fighting game sequel to the...ahem...visual novel Tsukihime.
Dun dun dunn?
....
Shiki Tohno is the main protagonist.
He's really from the Nanaya family, but they are all dead, so he was adopted into the Tohnos......

The Tohno clan also had a son named Shiki, but he goes insane in his youth due to the family's demonic blood awaking in him, and he is locked away only to become the next (and last) reincarnation of the evil vampire named Roa...

During the confrontation between Shiki1 and Roa, he tells him "I'll show you what it means to kill things", thus the line in my sig.

There's a lot more, but its rather quite deep, complicated, and crazy....
Unless you wanna hear about it, I'm stopping all the backstory for now.

Melty Blood Re.ACT is my second favorite fighter ever, right after Garou Mark of Wolves...

Whew, didn't mean to make such a bloody long post.
