Haō Taikei Ryū Knight

Lord of Lords: Ryū Knight (覇王大系リューナイト) is a Japanese manga series written and illustrated by Takehiko Itō. It was originally published 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. It also gained two OVA series comprising 17 episodes total, as well as two video games.

Plot
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). He is on a quest to seek the Earth's Blade, a gigantic sword which is capable of reaching 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. Together, they partake on an adventurous journey in which he comes across many villains, at first composed of thieves and bandits who are after the Ryu mechs, which are far stronger than the normal mechs (henceforth referred to as Solids). The plot expands as the series progresses.
