Magic Knight Rayearth #1

This omnibus edition collects the first half of CLAMP's classic fantasy manga series, originally serialized in the early 1990s. It follows three schoolgirls—Hikaru, Umi, and Fuu—who are transported to the magical world of Cephiro and tasked with becoming the legendary Magic Knights to save the land from a mysterious crisis. Dark Horse's 2011 release compiles the story in a single large volume, featuring the complete first story arc of the original run.
