Lambdadelta takes over as Game Master following Beatrice's defeat at the end of the previous arc while Bernkastel takes primary control of the human side in the game. Battler meanwhile tries to understand the truth behind Beato's games and comes into conflict with Erika Furudo, a detective character created by Bern who approaches the island murders from a "mystery" perspective, in contrast to Battler's "anti-fantasy" stance. The chapter also has a focus on Natsuhi, who receives threatening phone calls from a "Man from 19 Years Ago".
