Katawara Usagi is one of ShiroUsa(P)'s deleted and lost works.

Clip 1 and Clip 2 are the only surviving remains of this song.

To see my attempts to rescue this song, check out my related blog!

For info(In japanese, requires a translator if you dont understand) about the producer, visit this page.

An image that I believe was from the song, although unconfirmed, is found on pixiv.
