Watched the raw for ep1: it's just like the first season and continues where the first season left off. Plus new OP/ED. The new songs aren't bad, I can grow to like them but "Scramble" (guru guru mawaru) is still better.
But the raw I watched included the commercial for the single for the new songs by Tokito Ami and she is cute as hell. She wears glasses, cute face, ^_^ eyes, and school uniform says jailbait (I think she's 18 though, so legal

). I know CPOK would love her. The snipets of her video alone makes downloading the raw worth it.
Oh yea, remember at the end of season1 School Rumble did a preview for the next episode that involves a battle-royale type game to determine what the class is doing for the cultural festival? That appears to be ep2 of season2.
