Lured by promises like “Get 100x rewards for simple island quests!” and “Limited-edition island ramen, exclusive sweets—sweet and spicy treats all practically free!”, Chiikawa and the others decided to go on the island retreat. Boarding the ship alongside Rakko, who was suspicious of the flyer's contents, the group landed on the island... only to find something waiting for them there...!?
