Rudo is a scrawny 14 year old with white (fading into black) hair. His vital instrument is a pair of watchman gloves that allow him to turn "trash" items into something to aid him in battle. He likes eclectic things and believes that every item has a purpose. He serves as a trainee and younger brother figure to Zanka Nijiku. Zanka trained him when he joined the Cleaners and is almost an older brother to him As a result of being physically abused and eventually abandoned by his parents, Rudo became an emotionally closed-off and introverted boy, holding an intense pain and anger that would never stop burning inside him. Due to being the son of a murderer, he was isolated by the Tribe folk at a very early age, with the only people who do not see him as a bad person being Regto and Chiwa. Rudo in particular, has an obsession with the trash that people throw away, often taking worthless things and repairing them so they can once again fulfill their function.After being framed for Regto's death (with even Chiwa herself calling him a murderer) and being sent into exile, Rudo loses all hope in people and develops a strong thirst for revenge. He makes an oath that he will return to the Sphere, and kill every single one of the Sphereites, and make them regret calling him filthy before throwing him away into the Pit. Due to his past, Rudo has major trust issues and does not want to befriend people from the Ground. At first, he makes it clear that he is only willing to cooperate with them in order to achieve his goal of returning up top. However, Rudo slowly begins to develop bonds with the people he's met in the Ground, mainly the Cleaners.Rudo is an incredibly determined individual, and once he puts his mind to something, he won't stop until until he achieves it. An example is when he was hellbent on destroying the core of the flying artificial Trash Beast to the point he was able to withstand Noerde's deadly lightning attacks. Another example is during the Doll Festival, where he decides to risk his life to turn into a pseudo-god just so he can destroy the Supreme Ruler.Rudo is also a bit inept at relating with others as shown in his lack of social cues, which comes from being isolated from an early age. Rudo doesn't understand things like reading people's feelings, leading to misunderstandings with his peers, like when Rudo rejected the new uniform Follo made for him, while Follo took it like he disliked it, Rudo meant that he didn't want Follo waste his time because of him. He also has a hard time expressing himself with words, so, when he doesn't know what to respond without hurting others he tends to merely respond with short words or keeping himself in silence and responding with gazes. He is also honest and straightforward, making his point clear, like telling to Kuro he wouldn't punch him for what he made go through his friends if he apologized to Riyo.
