Lucky☆Star follows the daily lives of four cute high school girls—Konata Izumi, the lazy otaku; the Hiiragi twins, Tsukasa and Kagami (sugar and spice, respectively); and the smart and well-mannered Miyuki Takara. As they go about their lives at school and beyond, they develop their eccentric and lively friendship and making humorous observations about the world around them. Be it Japanese tradition, the intricacies of otaku culture, academics, or the correct way of preparing and eating various foods—no subject is safe from their musings.

The OVA features six separate stories revolving around the cast, some of which border on the bizarre; one of which is an MMORPG environment being played by Konata, Kagami, Tsukasa, and Nanako Kuroi, and another in which Kagami has a suggestive dream about Konata. (Source: Wikipedia)

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. (Source: ANN)

When Fujiko acquires and memorizes papers called the Columbus Files, she is attacked and loses her memory. Lupin, a treasure hunter named Rosaria, and the cackling villain Nazaroff all pursue Fujiko, as she is the only key to the location of Columbus' Egg, a treasure connected to the mysterious Orgone Energy.
