Little Illya's life has gotten completely out of hand since the Kaleidostick Ruby granted her the powers of a magical girl. Now a regular beach trip is going to turn into another crazy mystery adventure that she and her friend Miyu will have to unravel.
The story follows Issei Hyōdō, a dim-witted, lecherous second-year high school student who is killed by a girl on his first date ever. Issei is reincarnated as a devil, and from that day forward, he serves as an underling of Riasu, a high-level devil who is also the prettiest girl on Issei's campus.
During the construction of the Kurobe Dam, an ancient artifact was discovered, and so the United Nations Kurobe Research Institute was established. Intellectuals from all over the world gathered to study the object, and the children of those researchers attend Mt. Tate International Senior High School, including the institute head's daughter, Yukina Shirahane. In the summer of 2016, a lone samurai once again awakens.
Panty and Stocking—the Anarchy Sisters—are two nasty-ass angels who got booted from the pearly gates for being foul-mouthed bitches! Now they spend their nights blowing up ghosts in the seedy abyss between Heaven and Earth. Panty likes sex, Stocking likes sweets, their afro-sporting main man Garter Belt has a fetish we can't mention. Together, they're turning the mean streets of Daten City into a buffet of bodily fluids. Ghosts don't stand a chance against their lingerie of mass destruction, and if this debaucherous duo can collect enough Heaven Coins, they just might get their halos back. It's a slim chance in hell, but anything can happen when you're rolling commando, especially with Panty and Stocking!
