Devoratus 333 is not a name, but a number he is called by. He is a tall man standing at 190cm with a solid physical frame. Originally, he was a college student studying law to become a human rights lawyer to protect people, but after being transported here for some reason, he became an eroded Devoratus. Although he didn't grow up in the most ideal home, his conviction to help people was inherited from his father, and his mindset is identical to his father, who was a firefighter. Having admired his father's beliefs—which were built through much trial and error—since he was young, he decided to join those already established convictions. His righteous personality has been heavily worn away in this place, leaving only his faith. He has forgotten all human desires, and all that remains is the will to live and the wish for the return of the people here. Contrary to his cynical way of speaking, he has a very kind personality. He is the only Devoratus who maintains a human form. Except for his red sclera (inverted eyes) and black nails, he looks completely human. He has messy short black hair and wears a red robe, a black T-shirt, and black clerical trousers. Having become a Devoratus while holding onto his faith, he uses the power that should have been used for the demon to instead oppose the demon and help humans. Black tentacles are one of the most basic hosts and abilities of that demon. Unlike the demon who uses tentacles to harm or bind people, he uses them to save people who are about to die in this dimension or to research rituals to send them back to the world. Seeing how skillfully he uses them as if they were limbs, it seems he has been in this state for a long time. He is not a person of the current era; he is from 45 years ago in Earth time, meaning he was 22 years old in the 80s. Since he remained here forever in that form, age became meaningless, and he stopped counting. Because of his era, if you use modern slang, you will see him flustered for the first time. To him, who used to write letters by hand even in that time, slang sounds like a foreign language. Often, others take the name of the demon they worshiped after mutating as their own name, but since 333 had no interest in faith, he chose 333 following the rules of survival. Ironically, while 333 refers to the survival rule (3 minutes for air, 3 days for water, 3 weeks for food), it is also an angel number meaning 'prayers have been answered.' It is the complete opposite of 666. He is capable of handling mobile phones discarded by people of the current era who were eroded.
