♪ Morning Sun : mega
The song is used as the theme for the movie Neko Nanka Yondemo Konai.
By the way, If you're looking for Chiisana Honoo's mp3, I got it uploaded HERE (but it's actually mp4a) and its PV HERE. I didn't post the song because it'll be released as one of the tracks of Yellow, also including Morning Sun. ^^
