[Still bristled up like a cat, Katsuki nods immediately at Louis' question. Not necessarily the ego one, but the other question he for sure wants to happen.]

Yeah, I do. But it ain't an ego thing for Heroes. It's an ego thing for me.

[Surprisingly honest... but he doesn't want Heroes to get a bad name because of his own shenanigans. He's just a really weird kind of Hero, don't use him as an example of the rest--]

I like the idea of having fans. And fans wearing and buying merch of me. It sounds... cool.

[He's still a kid, with his dreams and ideas of what is and isn't cool... he absolutely sees nothing wrong with people wearing his face... though he does suddenly seem a little bashful when he's admitting it out loud. Maybe it's a little cringe....]
