The Kuraigana Island is a dark and gloomy place somewhere in the Grand Line. It was once the home of the now fallen Shikkearu Kingdom (シッケアール王国 Shikkeāru Ōkoku?, Muggy Kingdom in the Viz Manga and FUNimation subs). The forest island is relatively deserted except for some ruins. Amongst its landscape, the island possesses unique hills. This island is also the residence of the Shichibukai, Dracule Mihawk. Roronoa Zoro was sent here by Bartholomew Kuma during the events of Sabaody Archipelago, and spent two years on the island honing his skills.
Nine years before the current storyline, a terrible war was fought on this island. The Humandrills inhabiting the forest, gifted with the capability of learning from humans, watched the conflict, learned how to fight using weapons, and became fearsome fighters. At some point after the war's end, Mihawk arrived on this island and made the castle his home.
Roronoa Zoro was later sent to this island by the same Shichibukai. The two met up with Mihawk as he returned from the Battle of Marineford. Mihawk told Perona about Moriah's presumed death, and gave Zoro a little boat to return to his crew mates, later telling him about the island's history and warning him about the Humandrill' threat.
This is where Zoro trained under Mihawk for two years.
Eventually, Perona and Mihawk began to revitalize Kuraigana Island by tilling the battle-torn land. Seeing this, the violent Humandrills learned how to become peaceful and changed into friendly, helpful farmhands.
Anime and Manga DifferencesEdit
Originally in the manga, the Humandrills were simply hinted at with a silhouette in Zoro's cover story. In the anime, they were given a slightly more detailed foreshadowing with them attacking Zoro in the ruins as ape-like silhouettes.
