[Ironically, Bishamon's main outfit was a leather bikini skirt with knee-high leather boots and a whip... Though there's a very good reason (or three) that Yato decidedly didn't go for that one. He likes living for one, and he has a tiny bit of dignity for another. Though he doesn't mind explaining things about his current costume; he can be just as much of a fanboy as Katsuki when it comes to those he admires.]

Ah, saving them up, huh? [As someone who has never had a birthday or anyone to celebrate it, he's not entirely sure of the protocol when it comes to receiving large amounts of gifts. Whether it'd be impolite to not wait or whatnot. Maybe it's personal preference? Either way, it's Katsuki's party, so he figures whatever method the kid decides to employ is best. So no pressure from Yato either way!]

That sounds good! You can tell me if you like it or not, and if it's not something you want, I'll make sure to get you something else.

[He's hopeful that it will be something to please Katsuki, if only on the off chance he might get a smile out of him. He's still working towards that goal!]
