Rye Khalkeus

Rye Khalkeus (ライ カオキアス, Rai Kaokiasu), is a martial artist wandering the land of Ishgar. Part of the majority of humans unable to use magic — as only ten percent of the world's population are actually innate magic users — Rye focused instead on training his body, and became a martial arts master of world renown, able to fight on par with some of the greatest mages due to his sheer physical skill. This is in spite of missing his left arm, which has instead earned him the moniker of the One-Armed Master (隻腕の達人, Sekiwan no Tatsujin).

Trivia

 * Rye is Darkrai's second attempt at making a character who can fight on par with powerful beings despite being unable to use magic. His first attempt was a failed character called Lancelot, who still somehow wound up using "magic-y" things, which Darkrai wants to avoid with Rye.
