Takehiko

A driver and a rough and tumble guy. He regulates the electricity production in the town of Duomo. One of the lead members of Metal-age. Though a man of action and strong leadership, he fights for justice and devotes his life to overthrowing the government. He is often a target of Kuniko and Momoko’s teasing. Spoiler It is revealed that Takehiko was an agent sent by Atlas to watch over Kuniko, under the code-name #13. He strongly believes in the construction of Atlas, but this belief was shattered when he found out that his younger sister Yasuko was kidnapped by Atlas and used as a sacrifice with other children in the city's construction. Losing all hope, he attempts to kill Kuniko in order to ruin Atlas' plans but is stopped by her and Kunihito. He tells Kuniko her true role as the inheritor of Atlas before seemingly killing himself by jumping into a storm drain. He reappears at the ending where he tries to destroy Atlas.
