Second season of Mahou Shoujo Nante Mou Ii Desukara.

Lupin, Goemon, and Jigen take a mini-helicopter and head to the mysterious “Drifting Island” looking for a treasure rumored to be hidden somewhere on it. Through their exploration of the island, the trio encounters the lethal “Nanomachine,” the island’s security system. The trio triggers the alarm, springing “the Nanomachine” to life. The key to solving the island’s mystery lies in the small nation of Zufu. This once prosperous nation is now ruled by the ruthless, knife-collecting, General Headhunter. Fujiko does her usual probing and hacks into General Headhunter’s computer hoping to find some crucial information. Zenigata has received a video message from Lupin in which Lupin announces his desire for the priceless treasure. Oleander, a fiery blond officer with some hidden secrets of her own, steps in to help Zenigata. Armed with their newly found information, Lupin, Goemon, Jigen, and Fujiko go back to “Drifting Island,” but this time they are followed by General Headhunter.

Kotaro was pretty much supposed to be your average boy, worried about the pressures of education while enjoying a simple life with his friends. Much to his despair, he one day finds the overly cheerful Misha at his door, asking to be friends out of nowhere. Even more shocking is that Misha is an apprentice angel, yet she does more bad then good. Along with Kotaro's school friends Takashi and Koboshi and the so called devil Shia (once again being able to do more good then bad), the group of friends spend their days getting into all sorts of adventures and troubles. Based on the manga by Koge-Donbo.
