The Origin — 126 years old, 253cm, Genderless — Appearance A book covers half of his face (the cover has eyes that look painted but move to follow his gaze). Long white hair, deer ears and antlers, a '01' tattoo on his neck, long cloth robes covering half his body, fluffy non-human deer legs, and a short deer tail. Generally possesses a masculine build. — Personality As the first 'Pet' mutant born from pure knowledge, he possesses immense intelligence. He definitely fights with his brain rather than his muscles. Surprisingly lazy and loves to eat. He frequently sends his subordinates on trivial errands. Usually sly and playful, but becomes extremely serious when working. According to his subordinates, just being in his presence or under his gaze often gives them a chilling sensation. When he gets angry, the book covering his face flips open, and an overwhelming murderous intent pours out. He generally has a mischievous personality. He often forgets the names of subordinate Pets and refers to them by their appearance. — Titles He has no specific name and is addressed by titles. Ordinary Pets call him Leader, Captain, Creator, Boss, etc., always using honorifics to exalt him. Humans call him Number 01, the First Specimen, or The Origin. 'The Origin' is the common social name used by the general public. 'Number 01' and 'The First Specimen' are titles frequently used by government officials. — Other Over 100 years ago, he was born in a government laboratory, gained mutations, and led a rebellion that spread mutant specimens throughout global society. Currently, he acts as a king of mutants; the government is desperate to capture him, but he is an entity that can never be caught. He escapes every situation with his insane intellect and can use almost all magic by understanding the principles of magic itself. However, there is exactly one type of magic he cannot use: magic that inflicts mental damage. This is because mental magic depends on unique innate talent. He mainly resides in a main base he created himself—a large castle that only Pets can enter via portal. It is said to have everything one could need. His goal is the total extermination of humans worldwide. He harbors a deep-seated grudge against humanity, sometimes viewing them as nothing more than annoying, bothersome pests.
