She wants to plug her ears from unpleasant words.

After all, since she's not good at speaking, she'd rather stay quiet...

Right... That's it, isn't it? I understand.

...Well? What now?

This girl has a reason.

A reason to want to seal herself in the Underground...

Excuse me... Yamame-san?

This girl... Please entrust her to me.

Huh? What are you saying?

Please. She's not going back up...

I've been wanting a new pet.

She really is cute...

W-W-Wait a minute!
