Published Mar 29, 2026; written by Adriano, GameRant’s Anime Features lead who has produced anime content for GameRant since November 2021.

The Grand Line contains some of the world’s most dangerous pirates, organizations, and locations.

Kuraigana is tied to the former Shikkearu Kingdom and was left devastated by war; Mihawk later made the island his home.

Whole Cake Island is Big Mom’s base, featuring a sweets-themed, childlike landscape with candy-like snow and buildings made of confections, but it’s an island to avoid.

Enies Lobby is one of the three main World Government strongholds located in Paradise.
