Clover is primarily about a young girl called Sū. In the cyberpunk world that she inhabits, the military conducted a search for gifted children nicknamed "Clovers", who seemingly have the magical ability to manipulate technology. Demonstrations of their powers include teleportation and summoning weapons from thin air.

Classified according to how powerful they are, the children were then tattooed with a symbol of the Clover Project, with the number of leaves on the Clover indicating their power. To date, Sū is the only "4-leaf Clover" discovered. Along with other "Clovers", Sū was imprisoned to prevent her contact with other humans, as the government feared that she might develop feelings and be used as a weapon to jeopardise the country's national security.

Being isolated from the rest of mankind, Sū craves for company, and as for her only wish, she asks to visit "Fairy Park." Her escort is Kazuhiko, an ex-military soldier who has been forced to undertake the task. It is later revealed that Kazuhiko and Sū are connected through their mutual friend Oruha

Kazahaya is rescued from freezing to death on the streets of Tokyo by another young man his age named Rikuou. Now Kazahaya rooms with him (who he dislikes for his attitude, even though he's grateful to him for saving his life) above the drug store they both work at, Green Drug. Both work for the mysterious store owner Kakei, while putting up with Kakei's "friend" Saiga, who is always teasing them. The strangest thing about Kazahaya's job is that he and Rikuou are often sent on "extra jobs" by Kakei ...which are different and stranger every time, be it to retrieve a book or a girls' school uniform. Kazahaya always accepts the "extra jobs" so he won't end up without money and on the streets again...but he really wonders what the purposes are of these "extra jobs".
