Katsuki squints at her teeth a moment before his gaze briefly flickers to the empty glass. Although for him the pieces of the puzzle being laid out do not add up to vampire.

It lines up to blood related quirk.

"If they're attempting murder, they got no right calling themselves heroes."

For all his tendencies to scream 'die' at his opponents, Katsuki's still got a heroic heart. He's got a lot of work to do atoning for some nasty things he's done. But he isn't a bad person.

Plenty of people thought him the kind who would switch sides in an instant. Including the people who called themselves villains. So although he won't admit it, he understands being labled 'villain' or 'bad'. He just doesn't understand letting those labels shape you.

"If that's what the 'heroes' of this world get up to, than they're my enemies same as any villain. I'll blow 'em all sky high."

He finally sits down, dropping into the chair across from Tielle's. He shoves his mask up, into his hairline. He's deemed her not a threat.

"You said it's peaceful here, but when that shield falls, all hell must break loose. Tell me about the major threats."

If he's going to be here a while, he's got to know what to look out for.
