Kurenai, Ken

紅拳

The pilot of "Red Baron". He enters the Metal Fight primarily to become its champion. He occasionally clashes with Shouko and Robby. He harbors a secret crush on Shouko. When the two first met, Ken mistook Shouko for a boy; she revealed her face to him and kicked him in the groin in the series' first episode. He usually acts foolishly, but he can behave seriously and logically when the situation demands it.
In battle, he is a skilled strategist, capable of seeing through his enemies' techniques and exposing their weak points. A highly skilled martial artist, he trained in Muay Thai alongside Shadow since childhood, developing an early rivalry with him. One of his most common traits in combat is his refusal to give up, even after sustaining severe injuries (such as when Koumei tore off one of Red Baron's arms, or when Shadow ripped a cooling device from Red Baron's chest); however, this fighting spirit also enables him to win his toughest battles (by using his spiritual energy to give Red Baron a significant power boost). It is worth noting that his true name may not be Ken Kurenai, as when meeting Kumano in the first episode, he looks at a bunch of roses before stating his name (Kurenai being the Japanese word for rose, and Ken taking some time to come up with the name). (His name is translated as "Kent de la Rosa" in the Spanish version.)
