[Fine and all, but with Hiyori being a sweet person, she'll probably ask what Yato likes and the two can then go around and around figuring out what they're both interested in. Planning something together's a good way to find out if they're compatible. Have they done that before? Look into it.]

Are you trying to break it? [Who just hurls himself down on a piece of furniture like a meteor?! Even bounces on the cushions, dammit. He has to scramble to make sure his own food doesn't get jostled on his plate, glaring death at Yato for it.]

Damn, you really don't know shit about your own kind. [Katsuki had some understanding of that, and the why, which isn't a good topic to bring up-- ever --but this hits harder. Sheesh. Hell of a way to live. No wonder Yato spends more time with humans.]

Weapons can be used as tools to help, not just hurt. [He looks down at his own hand.] My Explosion will do whatever I want it to. When it manifested, some kids in my neighborhood were scared. They said it was only good for destroying things. Like a villain.

[What'd he do? ... OF COURSE HE BLASTED THEM!! Dumbasses, deciding for him what he was gonna do with his Quirk!]

But I'll use it as a hero, to help, save, and protect. Even if your shinki can only become weapons, you choose how to use them.
