Shougo Yahagi is a young motorcycle enthusiast living in a world of hot bikes, hard rock, and J-pop idols. The general populace go about their lives in peace, under the watchful eyes of a computer program in the guise of pop idol sensation Eve, unbeknownst to them. Shougo himself is mostly concerned with riding his motorcycle and picking up beautiful women like Yui Takanaka, who aspires to be a dancer. Shougo's life suddenly changes when his friend, Shinji Nakagawa, shows him a top-secret project: the "Garland," an advanced motorcycle that can transform into a robot. Ambushed by the military, Shougo hijacks the Garland and escapes into the city. Evading the military with the help of Yui and her friends, he gradually discovers that their idyllic society is only an illusion.

Two advanced civilizations, the Paranoids (a race of alien humanoids) and the Solenoids (who are all women) are waging a war that has gone on for centuries. When the Solenoid fleet leaves a battle to defend an experimentally terraformed world from the Paranoids, one damaged Solenoid ship, the Star Leaf, is separated from the fleet. Only seven women remain alive on the ship: Eluza, the captain, Rabby, the solid more or less main character, Lufy, the brash pilot, Catty, the mysterious science officer, Pony, the pink-haired ditzy tech, Patty, a solid crew member, and Remy, the cute one. After narrowly escaping the battle, the crew of the Star Leaf decides to continue with their orders and rendezvous at planet Chaos to defend it. It turns out, however, that their ship is the subject of a Paranoid experiment. In the end, it is up to the remaining crew Star Leaf to defend the artificial paradise of Chaos from the Paranoid fleet and the plans of the Solenoid leaders. (Source: AniDB)
