Samo-san is a rider so she didn't bring her Clarent.

Of course, she didn't bring her armor and helmet either.

Naturally, she didn't bring her panties either.

You think I'd bring extra panties with me?

Also, I can't believe you actually forgot to bring a pair...

Are you an elementary schooler?

How 'bout ya, have any extra panties?

...I do have a pair...

I didn't want to lend you this...but it can't be helped.

Oh! Thanks!

And the panties that Kiyohime took out

turned out to be mine.
