Capcom has released a trailer of their game adaptation of the conceptually wacky manga series Rosario + Vampire (Rosario and the Vampire). As you'd expect for a game based on manga and anime, the trailer spends most of its time showing some anime footage, then fits some actual gameplay in at the end.
Past the adventure-game-style location searching, past the cutscene of the poor protagonist being bitten by his vampire girlfriend (what did he expect?) and past the clicking-on-floating-hearts minigame, you can catch a glimpse of the unusual touchscreen-based combat. On the bottom screen, it looks just like an Ouendan-type thing. On the top, it's a 2D fighting game!
