Después de ser secuestrados por el culto Gorgom en la noche de su 19º cumpleaños, los hermanastros Kōtarō Minami y Nobuhiko Akizuki fueron sometidos a una cirugía cyborg con el propósito de convertirlos en los candidatos para ser los próximos Reyes del Siglo, guerreros destinados a superarse en la batalla final: quien gane se convertirá en el próximo Rey de la Creación. Kōtarō escapó antes de que le lavaran el cerebro con la ayuda de su padre adoptivo, y decide volverse contra Gorgom. Pronto descubre la horrible verdad de su padrastro: Gorgom mató originalmente a sus padres y, dado que tanto Kōtarō como Nobuhiko nacieron el día del eclipse solar, se los conoce como "Black Sun" y "Shadow Moon". Kōtarō, tomando el nombre de Kamen Rider Black, está decidido a rescatar a su hermanastro de Gorgom mientras protege a Japón. Sin embargo, más adelante Nobuhiko emerge como Shadow Moon para luchar contra Kōtarō y reclamar el trono como el próximo Rey de la Creación.
