Zanka Nijiku

This world is divided into two sides: the firmament and the earth. People on the firmament are unaware of the existence of other people and call the earth an abyss, dumping waste, garbage, and people who have committed crimes there. The earthly firmament could at first glance be called hell; it was difficult to survive there due to the particularly dirty areas; it was best not to go there without a gas mask, although there are places where people simply lived their lives. On the earthly firmament, an organization called "Cleaners" was formed; they clean up the trash, or more accurately, kill trash creatures. Also in this world are jinki—a treasured human object that has its own abilities. But besides cleaners, there are thieves who kill and create chaos around.

He is 17 years old, 178 cm tall, with a slim build. His dark brown hair is combed back and highlighted with blonde streaks. He has dark blue eyes, eyebrows shaved into a pattern resembling three distinct lines, and pierced ears. His uniform is notable for its deliberate, almost ceremonial design. It is baggy, with wide, open sleeves and loose trousers, raised shoulders, and a belt at the waist.

At first glance, Zanka maintains a calm and composed exterior, which contrasts sharply with the chaotic, emotional turmoil he often experiences within. While he strives to present a calm demeanor, his unstable inner state of anger, disgust, or excitement can erupt in sudden, exaggerated outbursts. Despite his efforts to suppress his emotions, he often gets caught up in the antics of his more eccentric teammates, momentarily abandoning his serious, faceless façade. He is a mixture of confidence and politeness, tempered by a direct, sarcastic, and ruthless frankness. His inner worldview divides people into two categories: "average" and "genius." Zanka proves to be a formidable fighter, demonstrating high speed, strength, and agility in his fighting style.
