Black Sun (Japanese: 仮面ライダーBLACK SUN) is a sophisticated, gritty reboot of the legendary 1987 tokusatsu icon Kamen Rider Black. Helmed by acclaimed director Kazuya Shiraishi and released as a centerpiece of the franchise's 50th-anniversary celebrations, the series—and its subsequent manga adaptations—reimagines the colorful heroics of the past through a dark, mature lens. It is a quintessential Seinen drama, trading campy action for a visceral, politically charged exploration of societal collapse and the blurred lines between man and monster.

The narrative is set in a fractured reality where Kaijin (humanoid monsters) live alongside humans, subjected to systemic oppression and violent prejudice. At the center of this turmoil are two estranged step-brothers, Kotaro Minami and Nobuhiko Akizuki, who were subjected to horrific experiments as children to become candidates for the next "Creation King." Fifty years later, as the world teeters on the brink of a revolution, the brothers reunite on a collision course. Their struggle is no longer a simple battle of good versus evil, but a tragic descent into the heart of government conspiracies, racism, and the brutal cost of change.
