Riku

Riku is a character in Xenoblade Chronicles 3. He is a mechanic in Keves's army and a companion of Noah, Eunie, and Lanz.

Appearance and personality
Riku is a seafoam-green Nopon with a fluffy tuft of brown hair on his head. He is equipped with Kevesi armor that covers his entire body except for his stomach and legs, and wields a gun in combat.

Riku is a strict, serious character. He is skilled both in mechanics and crafting, and takes great pride in his work. While often annoyed by the party's antics, he clearly cares about them and their well-being. Despite his serious demeanor, he can occasionally show a more silly side of himself, such as in the quest Unspeakable Being, where he shows concern over the concept of a creature more adorable than a Nopon existing.

Trivia

 * Riku's role is similar to Citan Uzuki from Xenogears.
 * Both are mentors to the main protagonists.
