And there's two new characters where one looks like pickle and another looking like some odd fat cat. I don't think they were originally in the manga.
....something called a Star Crystal has been stolen, and it's up to Negi to get it back. There's also a bunch of black blobs roaming around the campus (of which Asuna and the gang thought it was a chupacabara ) that has the ability to control people like it did to Evangeline.
Also Nodoka has made her pactio contract with Negi though we don't get to see her powers since she was nearly <s>raped by tentacles</s> captured by vines. Luckily, Evangeline saved her. And also, Asuna gets her second transformation which includes her using a fan.
That little RPG segment with Negi, Asuna, and Nodoka was pretty amusing. And there's a second ED sequence, and it involves dancing CHIBIS!!!
