Yakushi Usukubo chairs the Invader Rights Association, an activist group that's basically anti-Ranger and pro-coexistence. He's openly critical of the Rangers and actually sympathetic to the Invaders' side—not exactly a popular stance. His main goal is getting the Rangers disbanded so humans and Invaders can live together peacefully. Whether you see him as an idealist or a troublemaker probably depends on which side you're on.
