The Blox Fruits world is split into three Seas. You start in the First Sea and unlock the next one by reaching a level and finishing a short quest chain.
đ The Three Seas
3 seas| Sea | Levels | Starting island | How to unlock |

| First Sea | 1-700 | Pirate or Marine starter island | Where every player starts. Since Update 30 it has 40 Island Secrets that raise your level and stat caps and unlock island teleporters. |
| Second Sea | 700-1,500 | Kingdom of Rose | Reach level 700, talk to the Military Detective at the Prison to get a key, open the door in the Frozen Village cave and defeat the Ice Admiral, report back, then ask the Experienced Captain in Middle Town to sail you over. |
| Third Sea | 1,500-3,000 | Port Town | Reach level 1,500, give Trevor at Don Swan's Mansion a fruit worth at least 1,000,000 Beli, defeat Don Swan, then talk to King Red Head in the cells under the Colosseum and bring the boss rip_indra to half health. |
âšī¸ Level ranges and starting islands come from a guide updated in October 2026. The unlock quest steps come from older guides; Update 30 rebuilt the First Sea's look, but no source reports a change to these unlock quests. The 3,000 cap is from the official game description.
