On the surface, Zanka maintains a calm and composed exterior, a stark contrast to the chaotic, emotional turmoil he often experiences within. While he strives to present a placid demeanor, his volatile inner state of anger, disgust, or excitement can erupt in sudden, exaggerated outbursts. Despite his efforts to suppress emotions, he frequently gets caught up in the antics of his more whimsical teammates, momentarily dropping his serious, no-nonsense facade.

Described as a masochist,Jabber is a disturbed young man with a violent obsession for fighting. He adorns a wide grin when entering a battle and he usually only acknowledges those he considers strong, like Zanka, and is shown to be fond of people who can put up a fight, even sparing their lives after defeating them. On the other hand, he disregards those who he sees as weak, like Gris, who, in his words “wasn’t worth anything,” after defeating 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.

Above anything else, Riyo is a Cleaner with a strong sense of justice. Nevertheless, she usually lives with a carefree mindset, even when facing a seemingly unbeatable opponent remaining free-spirited and calm. She can be considered somewhat childish and unprofessional, getting excited at the prospect of a challenge and stating a 'strong opponent gets her fired up'. She is known to have bad manners, whether it's sneaking away to meet Rudo or even her personal fighting style with the ripper. She shows a particular interest in hair, playing around with Rudo's and asking if it's dyed or giving Trash Beasts a haircut, acting as a hairdresser.

Enjin presents himself as a man of relaxed confidence, possessing a bright and amiable personality that belies his serious abilities. Despite his remarkable talents, he remains grounded and humble, often introducing himself with the self-effacing title of an "average Cleaner". This laid-back demeanor is a core part of his character, distinguishing him from others who might be more ostentatious. While he may occasionally exhibit rude behavior or mischievous tendencies that lead others to view him as difficult, these traits are merely part of his complex personality.
