Well, it's 4 blu ray discs, sadly in Japane Blu rays and DVDs are priced incredibly high. you can pay 8000 yen for a 3 episode dvd sometimes, so most of the price will be the Blu-Rays. Plus by the sounds of things, it looks like it could be the eequivalent of season 1, aaaannnnnndddd, it appears to be a very limited run of the set = Super duper Collectorrs edition.
Wheel chair Girly? Hmm, yeh with that spider thing too! . Wouldn't mind that. She was hell creepy.
