Ricotte ~Alpenbul no Utahime~

Quark, a once-prosperous airship building town. If people are scarce nowadays, that's because there are only a few factories still in business.
In a pub in a corner of that declining town is a pianist acting as our protagonist and because of strange circumstances, a young lady calling herself "Ricotte" has ended up living together with him.
Innocent and willful, and furthermore being ignorant of the ways of the world means Ricotte is a severe torment to our protagonist, but notice that Ricotte has an unexpected skill in song.
On just a pub's stage the two of them gain acclaim for their performances.
And then, Ricotte's confession--.

"Have you heard of the 'Songstress'? That is me, that is what they called me."
