And, as the website now upgraded, it also has the PV preview for Mami’s next single Prophecy as well as more information on the single. The B-side track is now revealed and titled a frame. Sounds like a lame idea for me. Based on the current info, this B-side track apparently is not the ending theme song for OVA Shakugan no Shana S. Will the ending theme be released in a separate single? Still unknown, but… who knows?
Oh, thanks to Sekka for the information :D
