Haō Taikei Ryū Knight (覇王大系リューナイト Haō Taikei Ryū Naito?, lit. "Lord of Lords Ryu Knight") is a manga series written and illustrated by Takehiko Itō. It was originally serialized monthly in the Shueisha magazine V-Jump starting in 1993. A 52-episode anime television adaptation of the series was produced by Sunrise, directed by Toshifumi Kawase, and aired in Japan from April 5, 1994, to March 28, 1995. Due to its success, the series gained three original video animation (OVA) series.
Taikei Ryū Knight tells the story of Adeu, a boy who lives his life by the "Ethos of Chivalry" (a code of conduct similar to the Knightly Virtues), who is on a quest to Earth's Blade, a gigantic sword reaching to the sky from the ground. Along the way, he meets Paffy, who is a princess and her two escorts, Sarutobi, a ninja, and Izumi, a priest. Throughout their adventure, they come across many villains, mostly composed of thieves and bandits who are after their Ryu mechs, which are far stronger than the normal mechs (henceforth referred to as Solids).
