The luscious hills of Koumi Island are one of many reasons tourists pay its shores a visit—a reason that comes second only to its scenic coral reefs and the legend of Anne Bonnie and Mary Read. The museum that houses the cutlass and pistol of the daring pirate duo does wonders for the small island's tourism. On a trip to the island, the famous Kogorou Mouri is joined by his daughter Ran, her best friend Sonoko Suzuki, the Detective Boys, and Conan Edogawa. Following a mix up at the hotel regarding their rooms, the group encounters treasure hunters and becomes acquainted with the island's treasure fever. Sent on a hunt of their very own, the Detective Boys scour the isle; while in far harsher waters, Conan discovers a murder. The police, following a clue from a recent robbery, arrive soon after, and Koumi is plunged into chaos. What follows is a mad dash by not only the treasure hunters but also the inhabitants of Koumi to secure Anne and Mary's long lost booty. All the while, however, Conan, Kogorou, and the police search for the one thing far greater than riches—justice. [Written by MAL Rewrite]

The Eto Rangers ride in Space-Time Transmitting Machine Kirinda to repair the Novel Worlds of Mugen. The Eto Rangers themselves are anthropomorphic animals, each representing one of the 12 Chinese zodiac animals (and The Twelve Branches in Buddhism). In Japan they are known as the Eto animals. The Novel Worlds are stories created by the human imagination, such as old folk tales as well as newer books. These living worlds play out repeatedly, and are necessary for the good of humanity. Princess Aura rules Mugen, which is an island continent hanging over an ocean from the skybound Novel Pole. The Great God Goal gives her power, but she may never leave the small palace island area. Their nemesis is the forgotten Spirit of Cats, Nyanma (real name, Chocolat), who was excluded from the choice of 12 protectors by being disqualified from the race (in actual legend there are many versions of this story). She seeks her revenge by distorting Novel Worlds with Jarei Monsters. When a Jarei Monster goes to a Novel World they alter the story, turning it into a different version, sometimes a parody of itself. Bakumaru, the Spirit of Mice, must use the Genmakyou mirror to reveal ("Jarei Shouran!") the evil spirit once enough clues lead to its identity. Often the Eto Rangers must play out some of the story to find out who or what it is, sometimes even taking on the role of one of the characters in the tale. After defeating the creature, Kirinda is called when Bakumaru holds up his hand with one of Aura's 12 gems on it and calls out "Daikourin Kirinda!" Kirinda descends from a dimensional slit and purifies the evil spirit with a beam weapon, calling out "Jouka!" (Purification). (Source: Wikipedia)
