["My friend Ayaka." He's pretty sure that's the Shirasagi Himegimi, but it's not a huge surprise to him that Yoimiya is friends with her, given the nature of her work with fireworks. But it makes him wanna challenge the both Yashiro Commission's leads, but unfortunately that'll have to wait until much, much later.

Right now, he's going to help Yoimiya start her journey into cross-weapons training :D]

Why don't you make one with your own powers instead?

[See: Tartaglia does not know if pyro elemental abilities will burn their owner. I don't even know if they'll burn their owner if they make a weapon with it alkfj;slfj]

Then you can start right away with one perfectly balanced and made just for you.
