Katyusha and Erika have songs in common

Itsumi Erika

Another boring day without practice...

Itsumi Erika

(Commander Maho is away at a meeting. What am I supposed to do now?)

Katyusha

This bench is too big for Katyusha! And Katyusha is bored!

Katyusha

Where is Nonna when Katyusha needs entertainment?

Katyusha

Hmm hmm hmm...

Katyusha

(That song always makes Katyusha feel better...)

Itsumi Erika

What are you humming?

Itsumi Erika

It sounds... familiar.

Katyusha

It's Katyusha! The song I was named after!

Katyusha

Surely even a Kuromorimine soldier knows of its greatness?

Itsumi Erika

I have my own song too, you know.

Itsumi Erika

Hmm hmm hmm...

Katyusha

Wait, teach Katyusha! Katyusha wants to learn your song!

Katyusha

And Katyusha will teach you hers in return!

Itsumi Erika

Who knew we'd find something in common?

Itsumi Erika

Same time tomorrow? We can practice both songs.
