Geneon’s KOTOKO page announced more info on BLAZE, including this little edited tidbit: It is Takase!
Opening to Shakugan no Shana II
Composed: Kazuya Takase
Arranged: Kazuya Takase
That changes expectations entirely, but not the anticipation, even though the last anime theme C.G mix produced was… Chercher. (EDIT: Thank you, Lord DMC. C.G Mix did Shichitenhakki.) I’m assuming this will be much closer to Face of Fact. The site also has released the name of the ending theme, but nothing else. The name is “sociometry” which Wikipedia defines as “a quantitative method for measuring social relationships.”
Wouldn’t that be more appropriate for a dating sim?
Anyway, just-announced eroge “Furifuri” says that I’ve is producing their theme song(s). No exact release date nor exact music info is available.
