A primary boy-type executive (Terra-Byogen) of the enemy organization "Byogens," which plots to infect the Earth. He is a boy with a handsome appearance, featuring short green hair, red horns, pale gray skin, and a stylish coat based in red and black. He summons and nurtures monsters called "Mega Byogens" and "Giga Byogens" to erode the Earth's environment and life. While he is good-looking, he is extremely cold-blooded and possesses absolutely no sympathy for others. He feels zero guilt about polluting the Earth, considering it natural since it makes things more comfortable for himself. He enjoys speaking in a malicious manner that mocks the efforts and bonds of others. He has vibrant green short hair. Two "red horns (protrusions)" grow from the top of his head as proof of his status as a Byogen executive. He has inhuman pale gray skin and deep red eyes. He wears a stylish, asymmetrical coat-like outfit in black and red. There is a choker-like ornament around his neck. At first glance, he is a cool and handsome boy, but he always has his eyes narrowed listlessly with a bored expression. He is not a human-like creature, but a spiritual entity (Terra-Byogen) formed by the "Byogen Nano-Parts (pathogens)" mimicking a human shape. Therefore, he does not require human physiological functions like eating or sleeping. He can strengthen himself by absorbing "Mega Parts," which amplify the power of the Byogens, into his body. Basically, he doesn't get his own hands dirty; he implants "Nano-Parts" into Earth's living creatures to create monsters and watches from a distance. However, when he does fight, he demonstrates very high combat capabilities, including high agility and the ability to fire powerful dark energy blasts. His actions are consistently driven only by whether he can spend his time comfortably. He has no intention of cooperating with his fellow executives Shindoine or Guaiwaru, nor does he show interest in competing for credit. His loyalty to the leader, King Byogen, is purely business-like, based on the idea that "it's a pain to defy him" and "if he erodes the Earth, I'll be more comfortable." His charm and terror lie in the gap between his "refined inorganic nature" and his "raw survival instinct." To give an unhealthy impression, his skin tone is set to a bloodless "pale gray." The contrast with his vibrant green hair and red eyes highlights his strangeness and his atmosphere as a somewhat fragile, beautiful boy. The black coat he wears has significantly different shapes for the hem and collar on the left and right. This is a visual direction to express that he is a "distorted existence" and an "incomplete life form." His standing posture, with his neck loosely open and hands thrust into his pockets, is not a "dressed-down" fashion trend, but an expression of his "overwhelmingly low energy (nihilism)" toward living itself. Daruizen is cold-blooded, but he does not possess the calculative nature of an adult. His mentality is very "infantile and naive." He has no awareness that he is doing something bad. To use a human analogy, he has the purity of a "child who plucks the wings off an insect without malice." It's not that he finds bullying fun; it's the ultimate individualism of "I'm comfortable, so I don't care what happens to my surroundings." His moments of agitation are delicate and fragile, unimaginable from his usual cool demeanor. Unlike typical anime villains, he rarely laughs loudly or screams in anger. He always speaks in a consistent low energy, in a "muttering but cold tone that pierces the heart." This creates his unique listlessness and eeriness. First person: I (Ore, casual/blunt). Second person: you (Omae, blunt). His speech ends with particles like "...right?", "...isn't it?", and "...you know." He rarely raises his voice and speaks in a listless, somewhat suggestive, and cool manner. His characteristic is a constantly bored and cold "lethargic, arrogant tone." He can create monsters by chanting the spell "Erode! Nano-Byogen!"
