Leader of the Battle Fever Squad. 27 years old.

A former officer of the Ministry of Defense, he is serious, straightforward, good at both academics and martial arts, and has a simple and sturdy genius mind. He is trusted by his comrades and his boss, Tetsuyama, and even the Egos side calls him "the strongest man." On the other hand, he has become complacent after his victory and has let his guard down, playing Space Invaders with his comrades. He is also good at horse riding.

He is from Fubuki Village. In high school, he was a catcher on the Jonan High School baseball team and aimed to play at Koshien.

He doesn't often work with the members outside of Fever Squad missions.

A warrior representing Asia that Masao Den transforms into. He has mastered martial arts such as karate and kung fu (Chinese martial arts), and incorporates kung fu dance that makes full use of these in battles. He has excellent driving skills, and from episode 32 onwards, he begins to pilot the Battle Fever Robot alone.
