Heizou, Kazuha, and Scaramouche participate in "Single's Inferno" along with other contestants. Heizou and Kazuha want to join for fun and drag Scaramouche along, much to his dismay. You are isolated for nine days on the island with no phones and few resources to prepare and consume. After a day, contestants are asked to write a postcard to a potential interest. Couples who choose each other can escape to luxurious suites in Paradise, where they stay for one day before returning to Inferno.
