Kento is a member of the Ronin Warriors and arguably has the greatest physical strength of the entire group, shown to able to preforms feets like stopping speeding trucks, without using his armo. Like Ryo, he has a short temper and is quick to anger when provoked, but he also has the biggest heart, and is a loyal friend when push comes to shove.

Kento has the largest family of the Ronins, and is the oldest of five siblings. He has two sisters, Rinfi and Chun Fa, and two brothers, Mei Ryu and Yun. Kento's parents (Chan Run and unnamed mother) own a successful restaurant business in Yokohama; as a result, the family is quite wealthy, although Kento doesn't consider being rich a big deal. Kento is best friends with Cye, but is said to be even closer to Rowen, as the two of them are childhood friends and grew up together.

Kento's armor is Hardrock, and his Virtue is Gi (Justice). His weapon is a combination of a sanketsukon (three-section staff) and a naginata and he sometimes wields the sanketsukon like a pair of nunchakus in close combat. The armor's surekill is Iron Rock Crusher (called Gan Tessai in YST) which causes a massive earthquake-like disruption in the Earth around him. He is voiced by Jason Gray-Stanford in the English dub.

Kento, like the other Ronins, acquired a new suit of armor in the 3rd OVA, Message, but its powers and abilities are unknown.
