My name is Fubiki, I've just got assigned to this base by today!

Type 3 submergence transport vehicle, Maru-yu. Good to meet you.

Yes! Please take care of me from now on!

I-I-I'm so so-sorry.

I can't go to sleep without this...

I brought this from my home.

Sis, look, without this...

Maru-yu can't go to sleep.

I know.

Really?
