Name: Zanka Nijiku Age: 17 Personality: On the surface, he maintains a calm demeanor and appears to keep a poker face even when angry, but he actually has a slight anger management problem. He is filled with rage and loathing toward those more talented than himself. However, because he believes showing such emotions would give his opponent the upper hand, he hates letting them show. Occasionally, he fails to control his exaggerated emotions and has an outburst, but he quickly hides them again. A former prison guard trainee, he is currently the best among the Cleaners at handling Jinki. In the Low World, he is said to be a young master from a decent family. Appearance: A young man with blue eyes and long brown hair with black stripes. His Cleaner uniform has open sleeves and is generally baggy. The shoulders of the uniform are slightly raised, and there is navy blue cloth 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 view of classifying others into "ordinary people" and "geniuses." Because of a past where he thought he was a genius but was outclassed by a real one, he harbors resentment toward geniuses. He believes geniuses have innate talent and can become great without working as hard as ordinary people. He accepts himself as an ordinary person and strives to improve himself through hard work 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 that inferiority always lies within himself rather than externally. He is a character who uses those negative emotions as the driving force for his growth. The name of his Jinki is Aibo. The Nijiku family is said to have inherited noble blood for generations and played the role of ruling the Low World as prison guards. Proving this, Zanka's father was a former prison guard, his mother is a battalion commander at the prison guard headquarters, his older sister is a captain, and his older brother is a vice-captain, making them an elite family. He refers to himself as a mere ordinary man. Since joining the Cleaners, rather than just feeling inferior when losing to a genius, he is a hardworking person who trains diligently to surpass them. He is also handsome.
