So, based on what I read on the net,
Misaki Number One OST CD will be released on February 23rd and it cost ¥2500.
Still no list of the songs, but since it's OST CD,
Okay, that was just me hoping for kisumai on CD.
EDIT: Seems I was hoping too high and as the tradition goes there'll be NO No.1 ~ FIREBEAT on the OST CD just like the other JE songs in dramas.
