Kotaro Sakuma

Kotaro Sakuma (佐久間 小太郎) is a young boy who defied Jark Matter's occupation of Earth with his younger brother, Jiro Sakuma.

Character History
While the adults refused to defy Jark Matter to make it easier for everyone, Kotaro and his brother refused to accept the oppression, leading to them being caught up in the fight between the Kyurangers and Jark Matter which resulted in the boys being caught by Stinger who, though ordered by Eriedrone to kill them, decided instead to keep them hostage so as to force the eight Kyurangers to surrender their Kyutamas. The brothers' bond reminded Stinger, secretly a Rebellion spy operating within Jark Matter, of that he once had with his own older brother and so he told them to watch out for each other. Ultimately, while Eriedrone ended to kill the brothers regardless, Stinger dropped his facade at the last minute, saving the boys before joining with the Kyurangers to take down Eriedrone, raising the hopes of the previously disillusioned adults.
