Rio

In Tokyo Ghoul: Jail, Rio's personality before the "Jail" incident of being imprisoned is unknown, as he has seemingly changed greatly from both his time in Cochlea and Anteiku, casting aside any of his own personal needs, now only focusing on working to find out who "Jail" is and why he was imprisoned instead of Jail. A part of Rio's personality that remains is that he cares deeply for his unseen "Big Brother" who is thought to be imprisoned in Cochlea by Rio himself. However, he is more psychologically unstable than he appears due to the death of his older brother. Rio descended into a temporary state of madness and rage, killing multiple ghoul investigators, and as a result, gaining the epithet, "Jail."

Rio appears as a young teen with light green hair and purple eyes, dressed in a purple coat with a neon green interior, white and gray striped shorts, a gray shirt, and knee-high boots. The mask Rio wears depends on the Rc type chosen by the player, providing him with four optional masks. Each one seemed to be suited to his kagune. * If he is an ukaku, his mask has an insect motif to it, consisting of a visor with horns. * If a koukaku, his mask is a red helmet, that covers the upper half of his face with three slits. * If a bikaku, he will wear a gas mask with green highlights and a strap that goes over his head. * If Rio is a rinkaku, his mask covers his entire face, being slightly demonic in shape with narrowed black slits and exaggerated teeth with a dark green jaw. When his kakugan becomes activated, jail-bar-like markings appear on his face. Because of these markings, he was given the nickname Jail. Rio_ukaku_mask.png|Rio's ukaku mask.

A unique mechanism of the game allows Rio's Rc type to be determined by the player. As such, he has four potential kagune, each with a V2 and V3 version as the player upgrades it during game play.
