The song: http://www.youtube.com/watch?v=_dtgUoBky_Q

Are there sheets for basically the background piano? Or I guess just any sheets for the song in general are fine too.

Thanks in advance. :D

I started one a long time ago but never finished it due to lack of time/interest. Nevertheless it still contains the complete first verse and chorus. It is transcribed from the album version with piano accompaniment only. I haven't written out the melody line yet, but if you are familiar with the song you can just sing it while playing the accompaniment. Here is the incomplete score in pdf, if it is of any use.

Edit: Links to incomplete version removed.
Now complete and can be found at my website (under Music: J-Pop or Game).
