How to Unlock Soul Dominion Island — Hogyoku Quest Guide
April 4, 2026
What is Soul Dominion?
Soul Dominion is a locked endgame island in Sailor Piece described as "A realm ruled by spirits". Unlike every other island in the game, you can't simply teleport there — you must complete the Hogyoku Quest first.
When you try to access Soul Dominion through the teleport portal, you'll see a lock icon with the message "Requires Hogyoku Quest". This guide walks you through every step to unlock it.
Requirements
| Requirement | Details |
|---|---|
| Starting Location | Hollow Island |
| Quest NPC | Hogyoku NPC / Quest Guide on Hollow Island |
| Task | Find 6 hidden fragments scattered across the map |
| Difficulty | Medium — requires knowledge of multiple islands |
Step 1: Start the Quest
Travel to Hollow Island using the teleport portal. Find the Hogyoku NPC on the island and speak to him to start the quest. He will assign you the task of finding 6 hidden Hogyoku Fragments scattered across the world.
All 6 Fragment Locations
The fragments are hidden across 6 different islands. Here's exactly where to find each one:
| # | Island | Exact Location |
|---|---|---|
| 1 | Snow Island | In the tree on the hill |
| 2 | Shibuya Station | Hidden in the station area |
| 3 | Near Manipulator Boss | Close to where the Manipulator boss spawns |
| 4 | Shinjuku Island | Inside the building near the spawn point |
| 5 | Slime Island | Behind the Slime Warriors |
| 6 | Judgement Island | On the edge of the island, near the spawn |
Fragment 1 — Snow Island
Teleport to Snow Island. Look for the hill with a tree on it. The fragment is hidden in the tree on the hill. Walk around the tree and interact with it to collect the fragment.
Fragment 2 — Shibuya Station
Teleport to Shibuya Station. The fragment is hidden within the station area. Search carefully — it blends in with the cursed environment.
Fragment 3 — Near Manipulator Boss
Head to the area where the Manipulator boss spawns. The fragment is located close to the boss spawn point. Be careful of the boss if it's active.
Fragment 4 — Shinjuku Island
Teleport to Shinjuku Island. The fragment is inside the building near the spawn point. Enter the building and look around — it's inside, not outside.
Fragment 5 — Slime Island
Teleport to Slime Island. Head past the Slime Warriors — the fragment is hidden behind them. You don't need to defeat the warriors, just run past to grab it.
Fragment 6 — Judgement Island
Teleport to Judgement Island. The final fragment is on the edge of the island near the spawn point. Look along the borders of the island — it's close to where you teleport in.
Completing the Quest
Once you've collected all 6 fragments, the Hogyoku Quest completes automatically. You can now access Soul Dominion through the teleport portal — the lock will be removed.
What's on Soul Dominion?

Tips
- Some fragments can be hard to spot — look for a glowing effect or interact prompt
- You don't need to collect them in order — visit islands in whatever route is fastest
- If you're struggling to find one, try jumping or moving your camera angle
- Make sure your stat points are allocated properly before tackling Soul Dominion content
