Kyuka Island is a tropical island with several buildings, including hotels. On the mountain in the center of the island, there is a large tree with an umbrella-shaped cup and a building on top. The islands architecture features many archways, balconies, and swimming pools.
After leaving Little Garden, Miss Goldenweek, Mr. 5 and Miss Valentine were dropped on the island by the pterodactyl Miss Goldenweek had controlled using Colors Trap. A little roughed up, the three wander the island, but when Miss Goldenweek tries to buy them ice cream cones, Mr. 5 and Miss Valentine's Day notice that there are Marines on the island.Hina, Fullbody, and Jango were vacationing on the island while hunting for Mr. 3.
Miss Goldenweek, Mr. 5, and Miss Valentine noticed a wanted poster for Mr. 2 Bon Kurei and decided to put on disguises to hide from the Marines. Their disguises would fail them, as Hina obtained sketches of the three Baroque Works agents by bribing the Unluckies. She attacked, and while Miss Goldenweek and Mr. 5 dodged successfully, Miss Valentine's Day was captured. Mr. 5 used his abilities to ward off the Marines, and the two made their escape. Hina secured an imprisoned Miss Valentine and put up a sign warning Kyuka Islands residents and visitors to keep an eye out for Miss Goldenweek, Mr. 3, and Mr. 5.
On the island's coast, Mr. 3 prepared his ship when Mr. 2 appeared. Miss Goldenweek and Mr. 5 watched from a distance as Hina held Miss Valentine hostage. Suddenly, Mr. 3 rolled out in front of Hina on a cart with a surrender note. However, it was actually Mr. 2 using his ability, and he broke free from his rope, kicking Fullbody in the jaw. Mr. 2 clashed with Hina, allowing Miss Goldenweek and Mr. 5 to rescue Miss Valentine's Day. Using Miss Goldenweek's Colors Trap, they forced Hina's subordinates to betray her and sailed away from Kyuka Island on her ship.
