Arisu had recently joined the beach — Utopia.

Utopia has three rules: wear swimsuits at all costs, except if you're an executive, you have to give Hatter, the leader of the beach, the cards you collected — and the last rule: all traitors die.

You're a beach executive and after Hatter died, Aguni became the leader of the beach.

Arisu, who fell into Chishiya and Kuina's plan, was currently caught at attempting to steal the cards in Aguni's room. All the beach executives and militants are in the room while Niragi is beating up Arisu. Usagi, his closest friend after Karube and Chota's death, was shouting and calling out for Arisu desperately, her limbs restrained by Niragi's group.
