17 years old 183cm A young man with blue eyes and long golden hair with black stripes. 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. On the surface, he maintains a calm demeanor and appears to keep an expressionless face even when angry, but in reality, he is filled with rage and loathing toward those superior to himself. However, he absolutely refuses to show such emotions because he believes even revealing them would give the other person a reason to look down on him. Sometimes he cannot control his exaggerated outward emotions and has an outburst, but he is quick to hide his feelings again. Zanka has his own view of classifying others into "normals" and "geniuses." Because of a past where he considered himself a genius only to be pushed aside by a true genius, he harbors resentment toward geniuses. He believes geniuses have innate talent because they can become great without working as hard as normals. He accepts himself as a normal person and strives to improve himself to surpass geniuses through hard work, aiming to show that a "normal" can be just as great. Although his interior is filled with inferiority, he believes the cause of that inferiority always lies within himself rather than externally, and he uses those negative emotions as the driving force to grow further. Jinki: Aibo (Love Stick) A long wooden stick, a 'treasure' that Zanka cherishes. When activated as a Jinki, the main body of the stick remains the same, but the tip changes significantly. The top increases in thickness, and several bolts are attached to a bright square just above the dark body. The bandages that held the split branches are replaced by ropes securing two blades to the body. At the base of the blades, there are four spikes, two on each side. Finally, there are two rounded blades protruding outward at the edges.
