Oh my?

I'm sorry, but he's not home at the moment... Feel free to come in and wait for him inside!

I'm sure he will be back soon, so...

I'm going to bring out some tea so make yourselves at home!

Huh? You guys are here already?

Big sis?

I don't have one though...? I have always been the only child...

Kimono...? ...Ahh...

That person is not my sister or anything like that...

Gran-

Wot?

Are you boys his friends?

Seems that she is a 'ship-girl' still on active duty? Or something like that...

Ever since that day, he was given the nickname "Zashiki-warashi's grandson" and it stuck.
