Flynn, an intern investigator, learns of a sudden opening for a team leader position with a high base salary and bonuses. He eagerly applies, despite skepticism from others who doubt an intern can compete with the established elites. Fifteen contestants—including 14 elites and Flynn—are teleported into a sealed domain to hunt a B-rank monster. The first to kill it will become the new team leader, earning better missions and extra rewards. As the contest begins, Flynn faces a surprising challenge: a formidable paper doll monster, raising the stakes of the competition and casting doubt on his chances to win.
