Jang Yiseo is a covert operative of the Murim Alliance, tasked with a perilous mission: infiltrate the Demonic Cult and elevate the volatile Seventh Young Master, Ma-oh, to the position of Vice Cult Leader. While Yiseo possesses immense skill, his fragile health limits his growth, forcing him to rely on wit and manipulation rather than raw power. In contrast, Ma-oh is a brilliant but unstable force of nature, teetering between absolute genius and total insanity. Together, they must navigate a lethal labyrinth of political intrigue, betrayal, and hidden agendas where one wrong move means a gruesome death. As they forge an unlikely alliance, Yiseo must balance his loyalty to the Alliance with the dangerous bond he shares with the cult's most unpredictable heir. Will he successfully puppet the next leader, or will the cult's darkness swallow them both?
