A demon named Black arrives in the human world not for conquest, but for content. As a self-proclaimed demonic YouTuber, Black seeks to expose the hidden sides of people, games, and hobbies by turning their darkest secrets and outlandish desires into material for his videos. His loyal companion is a high-efficiency assistant known as Camera-chan, a demon of the camera species who helps him record everything.

The setting shifts between the ordinary human world and the underworld, where Black’s demonic audience eagerly watches his uploads. Black often approaches humans with contracts or devil tools, granting them strange powers or fulfilling wishes in exchange for the right to film them. However, the fine print always works in his favor, leading to humiliating exposures that teach lessons while entertaining his viewers. A key human figure in this dynamic is Satoshi, who often serves as a guinea pig or unwitting participant in Black’s schemes.

One notable narrative arc is Episode 0, a prequel special that explores Black’s life before becoming a demonic YouTuber. This story uses biblical allegories, framing Black as a Lucifer-like figure whose original sin was making prank videos, leading to his fall. Another significant storyline involves Black pulling fictional characters from different worlds into a massive tournament. This arc escalates until Black confronts and battles his own creator, the manga author Satoshi Kisaichi, who appears as a photograph pasted into the comic’s artwork.

Originally launched as a manga by Kei Kisaichi in CoroCoro Comics and adapted into a web anime on YouTube by the studio Plott in 2020, the series has gained enough recognition to earn nominations for awards like the Next Manga Award. In 2026, it was announced that Black Channel would receive a full television anime adaptation, promising to explore its dark humor and satirical social commentary on a larger scale.
