Himeko and Zero stumble upon a life-sized castle made of candy! Himeko runs right in to start chowing down. Zero follows, but no sooner do they get inside than they find themselves trapped and at the mercy of an eccentric princess named Kashihime! Like Kurohime she also has magical bullets, but hers aren't quite perfected. Zero and the candy-grabbing Himeko just might make the ideal targets for Kashihime to test out her dragon bullets!
