Second Sea
The Second Sea is the intermediate sea in the game that players can access once they have completed the Military Detective's quest in the First Sea.
Description
Unlocking Second Sea
To access the Second Sea, the player must be Level 700 or above. Once they have reached this level, they must talk to the Military Detective , and they will receive a special key. They then must travel to the Frozen Village and go to the cave where the Ability Teacher is, opening the wooden door with the previously mentioned key. Inside the cave will be the Ice Admiral, who must be defeated. Once this has been done, the player can return to the Military Detective, who will tell them to talk to the Experienced Captain located on the left side of the Middle Town. Talking to the Experienced Captain will allow the player to travel to the Second Sea.
Spawning
Once the player completes the Military Detective's quest, they will be teleported to the docks of the Kingdom of Rose. These docks contain several important NPCs such as the Bloxfruit Dealer, the Set Home Point, are located near the first two leveling areas.
Difficulty
The Second Sea is still relatively safe, although it is still far more dangerous than the First Sea. The NPCs do much more damage and have more dangerous abilities, and the Aura also starts to become common in its islands, making Elemental fruits much less effective. Additionally, bounty hunting becomes more common, although it is less of a risk on islands other than the Kingdom of Rose.
Design
The Second Sea's designs are fairly basic, although they are much better visually than the ones in the First Sea. Most of the buildings with interiors are far better decorated, and islands in general are larger and more complex. There are fewer islands overall, but the size of the islands are much greater, with the Kingdom of Rose being the largest island in the entire game.
Fragments
In the Second Sea, a new type of currency called Fragments is introduced, which can be obtained in various ways. The player can use Fragments 
to buy Race Rerolls, Stat Resets, the Lantern, Fighting Styles, Kabucha, Microchips, and Blox Fruit Awakenings after successfully finishing a Raid for the specific Blox Fruit, etc.

Notes
- The player can skip going back to the Military Detective, as they already have access to the Second Sea even without talking to him.
- Awakened Buddha is one of the most efficient fruits for farming in the Second Sea, due to its M1 range being highly increased and its damage reduction.
