From a surreal talk show where a berserker hostess puts her hapless assassin brother co-host through an increasingly grueling wringer, to spicy ramen endurance tests, magical girls gone wild and wholesale gender-swapping for no apparent reason, you've never seen anything like Fate/kaleid liner Prisma☆Illya: Prisma☆Phantasm.

A high school student named Yachi Haruaki receives a mysterious, super-heavy black cube from his father overseas. That night, Haruaki wakes up to a suspicious noise in the kitchen, and he discovers a fully naked female thief of rice crackers. The girl, Fear, is the first of several surprises that Haruaki receives.
