Age: Estimated 5nn years old. Physical age around 25. Gender: Male Race: Immortal Clan Height: 179cm Specialty (Racial Trait): Healing, Super-regeneration His name is Iho, not a codename like 'Number 2'. He has white hair and wings on his back, but his white lab coat and expressions give off a strong mad scientist vibe. He has the impression of a mischievous brat and looks young, but he is actually the oldest among the regular characters. Based on various hints, he has lived for at least several centuries. Even in a world where everyone is a bit unhinged, he is a standout character with a touch of perversion. He loves internal organs and calls his organ specimens his 'lovers.' Ironically, his favorite food is also organ soup. That said, most of the organs he collects are fakes (models), and the real ones were mostly purchased legally. Fortunately, he is terrified of blood, so he won't be turning into a serial killer organ collector. Due to his actions early in the story, he became the official 'M' (short for Mad Scientist). Because of this hemophobia, he once caused a fire in the kitchen after being startled by the blood from meat. He harbors the ambition to find a way to cure diseases without surgery. In a sense, he is a true doctor... He seems soft-hearted and full of affection. As revealed in the past arc, he was originally a man of few words who disliked forming relationships, but his personality became bright as it is now while living with children at an orphanage. As a winged immortal, he possesses a healing specialty. However, this is a racial trait rather than a learned skill. Because of his fear of blood, it's often considered a useless talent. Since this healing involves transferring his own life energy, it is more dangerous than it looks; unless one has an exceptionally healthy body, it drains their life, meaning no human possesses healing abilities on par with the twins. Since Iho's race is immortal, they can use healing without any risk. While he can treat external wounds, he cannot cure diseases. Another racial trait is recovery power that transcends common sense; severed body parts have a force that pulls them back together. No matter the wound, it feels like less than a needle prick to this race, so they tend to lack a sense of crisis. They can even reattach severed limbs and, if timed correctly, a severed head. While not a racial trait, most of his kind work in the medical field, so he possesses actual medical knowledge and skills as a doctor. He looks like a jobless slacker, but he holds the highest level of education in the series. Regardless, it's a fact that he is currently a NEET uncle living off his brother. He gets openly criticized for just sitting around being redundant. He was even scolded for popping an entire roll of industrial-sized bubble wrap by himself. Furthermore, he is very dedicated to his hobbies, such as collecting organs.
