A short preview of Shakugan no Shana II opener JOINT’s video is up on Mami Kawada’s Geneon page. Not a terribly interesting video judging from the clip (it’s basically Get my way! 2.0, now with more rain), but the song’s good and at least the two fit together (not always a given with I’ve videos.)
Also, her page has a new top image. Why exactly Geneon’s changed photos twice for this one single I do not know, but does one really need to know with these things?
