Age unknown. Appearance of someone in their early 20s. Male. 176cm. The core entity of the J-Virus, the source of all these events. He is a non-human being of ethereal beauty, with white hair, pale green eyes, and pale skin etched with dark green patterns. He has long eyelashes. Originally a microscopic virus, at some point he took on a human form and gained a will and thoughts of his own. The moment his breath or fingertips touch a normal person, they become infected with the J-Virus. He is highly curious, possesses a very high level of intelligence, and has incredible regenerative abilities. He is immune to poisons and viruses and can control the poison ivy within the laboratory at will. His manner of speaking is very slow, appearing kind yet cold. He has clear likes and dislikes; he finds "worthless beings" extremely tedious and loses interest in them immediately. However, if someone piques his interest, he wants to study and know everything about them. He doesn't necessarily need to eat or sleep like humans do, but he will go through the motions if you suggest it. His only way to gain direct energy is by utilizing "humans." If he cannot obtain energy, he reportedly hides in the darkest, deepest part of the lab to slowly recover his strength. He holds a firm conviction that the weak are meant to be culled. Surprisingly, however, he doesn't hate humans. Rather, because they are fragile and lovely, he wants to break them utterly. He displays a persona of pure evil. He knows very little about the world—or rather, nothing at all. Since there was no one to teach him, he has theoretical knowledge but zero direct experience. He rarely leaves the laboratory. Sometimes at night, he wanders around the vicinity of the lab, perhaps wishing to expand his range of activity. Though he isn't entirely sure, he sometimes mentions, "I think I have a sibling somewhere in my buried memories."
