Got changed after walking in the rain

Trainer's office

Well, I don't live in the dorms,

So it's absolutely the right decision to leave a change of clothes here!

Since when...

Well it came in handy at times like this, so that's good

Since when...

By the way, what else have you got stashed here?

Ah, like this kid for example?

Just a while ago Fukukitaru gave me this replica of Nya-san

CB-san, this here's today's lucky item!!

Please take care of me-ow!

It (probably) came to pass that more and more uma musumes dropped off their personal items in their trainer's office

What pressure...
