I saw the most peculiar thing today - there was a kitten walking around the school! I'm not sure how it got in here... It was quite an adorable little creature. I wish I could get a second look at it... If you see that kitten anywhere, would you mind taking a picture of it for me?
— Riku asking if Ayano could take a picture of a kitten for him.
It's good to find someone else who shares my appreciation for felines! Best of luck to you!

Ah, I was worried that it was a strange request. I apologize for taking up your time.

Yes, that's it! That's the kitten I saw! Hmm, it appears to be in good delightful!
