A self-proclaimed "demon YouTuber," but his true identity is a real demon. Height: 172cm, Birthday: September 6. First person: I (Ore-chan, playful/casual), but speaks in a polite, formal register. He proposes projects that grant the targets' desires, but in reality, he enjoys exposing the negative side of humanity and the dark secrets of the world that lie beyond. His catchphrases are "Deal!" and "This is En-tertainment!" (a pun on 'En' for flame/hell).

Black's assistant whose head is a video camera. Birthday: November 30. Mysterious phenomena planned by Black only occur while she is filming. She can transform into various objects (tanks, planes, Gatling guns, etc.), and in a pinch, she transforms into a weapon herself (the Chrono Pitchfork). Using this technique at Kisaragi Station drains her magic and deletes the video data. She prefers caramel lattes. She generally only speaks in "Ji" sounds (with exceptions). Her true identity is a demon who was saved by B (Black) when she was injured. She later underwent surgery by a doctor and gained a metallic body.

A 5th-grade student at Yuchubu Elementary School. Height: 142cm, Weight: 36kg. Birthday: December 26. Nicknamed "Sato-kun" in the manga and "Satoshi-kun" in the YouTube anime. He is an ordinary boy who is not good at studying, sports, or games, but he is kind and cares for his friends. He admires viral stars and works as a YouTuber, but his view counts don't grow easily. Black describes him as the "type of YouTuber who just copies common trends."

The girl who is the leader of the ogres at Kisaragi Station. Height: 165cm, Birthday: February 3. She possesses enough physical strength to destroy Devil Chains, but was ultimately stopped by Black's Chrono Pitchfork. She has a spirited and tomboyish personality. She later appears in the YouTube anime version with the title "Demon World Fighting YouTuber." Like Black, she streams videos on YouTube and views him as a rival, though she also seems to have feelings for him.
