A natural 24-carat round brilliant cut blue diamond with a diameter of 23 millimeters owned by Rohan Kishibe.[2] It weighs 110 grams.[3] It has an estimated value of $6 million USD on the black market. Through her contacts at Kona International Airport's customs department, Meryl Mei Qi has been informed that the diamond has been brought to the island of Hawaii by a wealthy Japanese tourist who owns a villa there. She tasks Jodio, Dragona, Paco, and Usagi Alohaoe to steal it.
Initially, the diamond seems to display the ability to escape containment. It falls out of Paco's zippered bag twice, slips from Dragona's fist and seemingly teleports from their pocket into a cup.[4] This behavior is later revealed to be actually an effect of the Lava Rock.[5]
Hamburgers that Usagi Alohaoe buys at a shop at Kona Airport, stored in a paper bag that says "Aloha" with a pineapple on it. They have cheese and pineapple as toppings.

When the gang is attacked by Wild Cat Size, Usagi breaks apart the patties and mixes caviar into it before feeding it to the cats.[6]
Rohan's iPad which has files of half-finished Pink Dark Boy artworks, volcanoes, lava flows, and the Lava Rocks. Jodio secretly checks the images on it while Rohan is swimming. The rain from November Rain makes it wet after, so it is unknown whether it still works.
Caviar, also known as sturgeon eggs, that Usagi steals from a fridge at Rohan's villa.[3] Since it takes 20 years for a beluga sturgeon to reach adulthood, 40 grams of caviar costs $400, and it's double the cost if purchased at a Waikiki hotel. Usagi mixes the caviar into hamburger meat and feeds it to Wild Cat Size, making their bodies attracted to the Lava Rock.[6]
An original drawing by Rohan Kishibe of Pink Dark Boy. It is stolen by Usagi Alohaoe from Rohan's villa. Similar to the diamond, it mysteriously falls out of Usagi's zippered bag, leading the group to discover the true nature of the Lava Rocks.[5] They give the drawing to Meryl Mei Qi once they return to Oahu.[7]

An $80,000 luxury watch sold at the Diamotch shop which the salesman accuses Dragona and Usagi of stealing. After Dragona taps on it with the Lava Rock, the watch becomes attracted to the Lava Rock and follows it around.[8]Smooth Operators subconsciously takes it and places it inside Dragona's pendant alongside the Lava Rock. When the salesman takes the Lava Rock, the watch follows it and gets caught on his shoelaces before slipping away when he accidentally kicks it.[1]
Leo ends up buying it for his girlfriend.[9] After Charming Man attacks Jodio and the others, the watch falls off the woman's hand and Leo accidentally kicks it. It heads toward the ocean where Charming Man is holding the Lava Rock.
The watch ends up being swallowed by a fish and breaks, as the hand on the clock no longer moves. A fisherman who catches the fish sells it, and a hawker at Kona Airport gets his hands on it.[10] He tries selling it to Dragona for $800, but lowers the price to $80 when they notice it stopped working. Finally, he reduces it even lower to $30 after they point out that it fell into the ocean and smells like fish. Dragona gives it to Meryl Mei Qi after returning to Oahu.[7]
