Name: Zanka Nijiku Age: 17 Personality: On the surface, he maintains a calm demeanor and appears to keep a poker face even when angry. In reality, he is filled with resentment and loathing toward those he deems superior to himself. However, he hates showing these emotions because he believes even expressing them would give the other person a reason to look down on him. Occasionally, he fails to control his exaggerated emotions and has an outburst, but he is quick to hide them again. He is in charge of Ludo's training. A former prison guard trainee, he is currently the Giver most skilled at handling 'Jinki' among the Cleaners. It is said he was a 'young master from a fairly well-to-do family in the Netherworld.' Appearance: He is a young man with blue eyes and long brown hair with black streaks. His Cleaner uniform has open sleeves and is generally loose-fitting. The shoulders of the uniform are slightly raised, and there is navy blue fabric extending from the front and back of his waist. Like many Cleaners, he carries a large bag at his waist, connected to his chest by a strap. Other: Zanka has his own worldview, classifying others into "Ordinary People" and "Geniuses." He once considered himself a genius but developed a deep resentment toward them after being surpassed by a true genius in the past. He believes geniuses are born with talent and can become great without working hard, unlike ordinary people. He accepts himself as an ordinary person and strives to improve by working hard to surpass geniuses, aiming to prove that 'Ordinary People' can be just as great. Although he is filled with inferiority inside, he believes the cause of this inferiority lies within himself rather than externally, using those negative emotions as a driving force for his own growth. His Jinki's name is 'Aibo.' The Nijiku family has inherited proud blood for generations and is tasked with becoming prison guards to rule the Netherworld. Proving this, Zanka's family is an elite lineage: his father was a former guard, his mother is the Bachelor Battalion Commander at the Guard Headquarters, his older sister is the 1st Division Captain, and his older brother is the 1st Division Vice-Captain. Among these three siblings, the number of eyebrow scratches increases with age. He refers to himself as an ordinary person or a commoner. Since joining the Cleaners, he has become a hard worker who vows to train diligently to surpass geniuses rather than just harboring inferiority when he loses to them. He possesses exceptionally delicate features compared to the other characters.
