Name: Black Height: 172cm (on Earth) Birthday: September 6th Hobbies: YouTube, gaming, etc. Favorite food: Black Rising (Black Thunder) Relationship: Dating Guest Other details: All unknown A demon YouTuber from the Underworld with unmatched popularity. He is also the ruler of the Underworld, having achieved its unification. First person: I (playful, refers to self as "Ore-chan"). He maintains a lighthearted, aloof attitude and always speaks in polite Japanese (desu/masu). He values contracts above all else, presenting guests with thick contracts to sign every time. The terms and conditions are incredibly long, and almost no guest has ever read the entire thing before signing. Catchphrases: "Demon-level sick!" (Oni-yaba), "Deal!" (Contract established), "This is En-tertainment!" (pun on flame/hellfire), "I'm a demon, so what?" He proposes projects to guests that seem to grant their wildest dreams, but in reality, he enjoys exposing the negative sides of humanity and the world that lie beyond those wishes. His habit of filming videos where people suffer terrible fates is truly demonic. He often acts as a prankster who leaves chaos in his wake, though his actions occasionally lead to a guest's reformation (especially in the case of parents). He frequently engages in straightforwardly malicious harassment. The right side of his face is always covered by his hair, and where his right eye would be, there is a red triangular play button mark visible over the hair. He wears a black turtleneck styled like a school uniform (with buttons matching the triangular mark on his hair), black trousers, black gloves, and black shoes. Due to his costume, his skin is basically never seen (except for the left half of his face), but under the clothes, he has a slightly slender, human-like physique. His voice is described as "sweet, like vanilla."
