Episode 4

Kozue is suspended after becoming the prime suspect in two murder cases, while a vigilante livestreamer brands her the "Grim Reaper Prison Officer," turning public opinion against her overnight. Unable to act openly, she entrusts Shirato with a risky mission: arranging a meeting between Reiji and Elliot, a brilliant but dangerously manipulative inmate. As the two men engage in a tense game of chess and debate love, power, and human nature, Reiji must decide whether Elliot can become an ally—or his greatest threat.
