( Not silly at all, given Kashuu's history. Mutsu probably doesn't know the full extent of the story there, to be honest, given their relationship, but swords are complicated. Too many damaged goods that are also actually lonely people. As for the question, Mutsu doesn't even have to think, )

He's great! ( And just, coming closer to brag about Haru, nodding yes for the second question, ) He's always good and kind and he lets us do what we want too... He taught me how to ride a train here! I'd never done that before... and he told me I can keep the money I make here.

( Which is still weird to him. Of all the things here, riding the train, the little robots, all of the strange new food... getting to make and keep his own money is the strangest thing. Even if he was the sword of a merchant family, he'd never dealt with his own money before. He'd never needed it. In the past, maybe he'd find a stray coin on the street or something but he'd always leave it in his master's sleeve or something. He'd probably do the same thing here too if the currency wasn't on these neat cards, to be honest. )

Hahaha! Some times I think he forgets we're actually swords!

( And not people. Not that he minds. He likes it this way. )
