What's the tune that Noel is humming in Sora no Method? What's the tune that Noel is humming as heard in around 02:55 of Episode 5? It seems that Nonoka also knows that tune. It also played as the ED of Episode 7. Does someone know how to tranlate the credits? I think the title is stated somewhere there.
I got it. The title of the OST is Hoshi no kakera. Hoshi no kakera is 2nd ending theme by fhana. It is the ending theme of Episode 7.
