Texhnolyze takes place in the city of Lux, a man-made underground city that has crumbled after years of neglect and lack of repairs. Citizens of Lux have come to refer to their home as simply "The City" and treat it as though it has a mind and will of its own. Three major factions battle to control Lux: Organo, a group of "professionals" who collaborate with the criminal underworld that controls Texhnolyze (prosthetics), the Salvation Union, a populist group that seeks to disrupt Organo's business, and Racan, a collection of young individuals with Texhnolyzes that use their abilities for personal gain. Ichise was once an orphan who has made a place for himself in Lux as a prize fighter. One day, a fight promoter grows angry with him and the altercation that follows results in Ichise losing an arm and a leg. Before death can take him, Ichise is found by the scientist Eriko Kamata, who uses him as a test subject for her newly designed Texhnolyze. With these powerful new limbs at his disposal, Ichise begins to work for Oonishi, the leader of Organo. He soon meets a mysterious young girl, Ran, who has the power to see possible futures. Together, they soon realize that Lux is on the brink of war and collapse, and that they may be the only ones who can save The City.

Ranma Saotome continues his search for a way to become a normal teenage boy again. He gets into many hilarious situations involving the many girls in his life. One of the biggest challenges is overcoming the proposals from others who have found a suitable bride for Ranma. But he has his own worries and must muster up the best of his wits and martial arts to keep his sanity. It's not easy being desired by so many women (and men) and not breaking hearts of a few along the way. He just might be able to find it in his heart to confess to Akane or simply find another excuse that he can't marry such a tomboy girl. (Source: ANN)
