Zhao Hui, an unemployed young man, unexpectedly transmigrated to South Korea on Blue Star and was reborn as Yeon Jeong-hwi, an NSS field operative with an exceptionally handsome appearance.
During a cross-border mission, Yeon Jeong-hwi was killed in an attack by a powerful assassin. A mysterious stone, the Sun Emperor Stone, had been implanted inside him, and after he was bathed in mysterious sunlight, he miraculously returned to life as the "Child of the Sun," Kamen Rider Black RX. Now he must shoulder the immense responsibility of "defending Blue Star and protecting love and justice."
From then on, the lifelong bachelor Yeon Jeong-hwi found himself, thanks to the Emperor Stone's bizarre passive ability, suddenly surrounded by a whole host of people he had to protect with all his might and care for tenderly. But that didn't stop him from standing alone against evil forces and powerful villains, making the name "Kamen Rider" ring throughout the world of Korean entertainment!
"I am the Child of the Sun! Kamen Rider Black RX, protector of all life in the world!"
