PERSONALITY
Wise, stern, paternal, both a father figure and a strict teacher to the pilots of EXO-FORCE.

BACKGROUND
Aged and wise leader of EXO-FORCE, Keiken has a long history. It was he who first designed Meca One, the robot who later led the rebellion against the human race. It was also Keiken who founded EXO-FORCE and helped design their first battle machines. Stern, paternal, firm in his convictions and universally respected, Keiken provides the guidance the young pilots need.

At the end of 2006, Keiken made the decision that EXO-FORCE was too vulnerable in Sentai Fortress and that they needed an “edge” to defeat the robots. He sent Hikaru, Takeshi, and Ryo to find a legendary golden city, said to be located on the top of Sentai Mountain. Due to his experiences in the jungle as a younger man, he knew the city was no myth, and its technology no legend…knowledge that has now come back to haunt him.

Though noble and wise, Keiken is not without his flaws. He is burdened by the guilt of having created the very robot – Meca One – that originally rebelled and led the robot revolution years ago. He is also very protective of his granddaughter, Hitomi, whose parents died in the robot war. He tried to keep her from becoming a battle machine pilot to keep her safe, but eventually he was forced to acknowledge that she made a skilled and irreplaceable part of the EXO-FORCE team. Despite their shaky relationship, he respects her intelligence and skill and has named her as his successor as commander of EXO-FORCE.

Keiken believes that stopping Meca One is more important than his own survival, though he is far less willing to sacrifice his students than himself.

“My shoulders bear the weight of all that Meca One has done. All that I can do now is try to prevent him from achieving his dark goals.”
