I think Sayaka would adore trying out swords for his shop, or even just for sparring purposes. She'd think he'd be awesome!

Hana would adore and comment on his tattoos definitely, or at least hang around him. Obviously Hanzo knows about dragons! She'd also want to try being a 'drining buddy' of sorts.

Nanaki wants to pester him to no end but they do admire their strength from afar. Sempaiiiiii
