The Hero of Lacroa

The Lacroa Kingdom is on the verge of being conquered by a figure calling himself Satan Gundam. Suddenly, a Gundam appears in the land, saves Lacroa's Princess Fraw from an attacking monster, and is granted the title of Knight by King Revil. Entrusted with a fragment of a stone slate that tells of legendary sacred artifacts, Knight Gundam sets off on a journey with Gundank the Priest, Guncannon the Warrior, and Knight Amuro to defeat the Demon Lord Satan Gundam.
