Everybody talking about Shakugan no Shana 3 and Shakugan no Shana s(ova)??
I think that Shakugan no Shana 3 will release after Shakugan no Shana S because between them Yuuji and Shana happened a lot of things such as yuuji become a bad guy"祭礼の蛇"坂井 悠二....This written in the novel...

~Hope season 3 will be release soon~
