Childhood Ruined: The Demon Lord Descends in Detective Conan

The Demon Emperor Ye Xiaokong, who had suppressed the righteous path of Shenzhou for three thousand years, was struck into the world of Conan by a Chaos Divine Thunderbolt. He planted dark seals on Ran Mouri and Ai Haibara, and used overwhelming power to completely subjugate Koizumi Akako, turning them all to the dark side and keeping them close to Conan and the Red Faction as undercover agents. He unifies the Black Organization and starts a covert war with the great detective who never stops searching for the truth, a game in which no one knows the truth. Once the game begins, it will never end.

Ran's allure, Ai's coquettish sweetness, and Akako's submission are shown to him alone. But Conan (Shinichi Kudo) and the Phantom Thief Kid will never discover that the person they trust is, in fact, the Demon Emperor's servant!
