Takaya Kuroda

The Isle of Koumi, a beautiful island in the Pacific Ocean. On the island, people pass an old legend down from generation to generation that there was the Seabed Palace, an ancient ruin at the bottom of the sea, where the treasure of 2 female pirates, Anne Bonnie & Mary Reed (who really existed 300 years ago), was left. When Conan and his friends visit Koumi Island while on vacation, they meet some treasure hunters. There was something suspicious about them.

Yuta Okkotsu is a nervous high school student who is suffering from a serious problem—his childhood friend Rika has turned into a curse and won't leave him alone. Since Rika is no ordinary curse, his plight is noticed by Satoru Gojo, a teacher at Jujutsu High, a school where fledgling exorcists learn how to combat curses. Gojo convinces Yuta to enroll, but can he learn enough in time to confront the curse that haunts him?
