Kinrei Kingen

His childhood name was Kinrei (金令). He was the only one that can hear the Prince's voice, so his name was changed to Kinrei (金隷), the one who serves the Prince. He used the Prince as a tool to grant his own wish. However, when the Prince chose to die rather than to become his tool, Kinrei then saw the Prince as a living person rather than as a puppet that sprouted emotions that the latter didn't have until then. He made amends with the Prince and together, they fight against Rakan's group. He abandons the world that is coming to its end and aims to become superhuman. Chigusa remarks that even though Kinrei appears to be just a human right now, the latter's composition was strange when he was younger.
