Summary
Riku is an eighteen-year-old Imanity who lived during the Great War on Disboard and serves as one of the main protagonists in Tet's story. During an expedition, he encounters Shuvi and voluntarily loses a game to her, resulting in him bringing her back to his colony. He bears a striking resemblance to Sora, sharing his black hair, slender build, black eyes, and facial features. Like Sora, Riku is a master strategist and manipulator, a skill demonstrated when he tricks the Nilvalen family matriarch, recognized as the strongest and smartest Elf of her time, into revealing valuable information, even though the feat comes at the cost of his health.
