Demonite Fragments are part of a progression quest in Sailor Piece that rewards players for exploring Academy Island carefully. If you are already at mid to high level, this quest becomes extremely easy, but new players often struggle because the fragments do not appear on the map and are tucked into elevated positions.
Below is everything you need to know to finish the quest fast and efficiently.
Quick overview of the Demonite Core quest
| Quest Name | Demonite Core Quest |
|---|---|
| Quest Giver Location | Academy Island |
| Objective | Collect 2 Demonite Fragments |
| Total Fragments Needed | 2 |
| Difficulty | Easy |
| Estimated Time | 3–5 minutes |
| Recommended Level | Mid game and above |
| Travel Required | Only within Academy Island |
The quest is straightforward, but vertical movement is important. If you have dash, sky jump, or mobility abilities equipped, you will complete this even faster.
Where to start the Demonite Core quest on Academy Island
The Demonite Core Quest NPC is located on Academy Island, which is easily recognizable by its training grounds theme and large structured buildings. When you approach the NPC, you will see the interaction prompt allowing you to talk and accept the quest.

Once accepted, your quest tracker will update to: Find 2 Demonite Fragments hidden in the world.
Both fragments are located on Academy Island itself, so you do not need to sail elsewhere.
Location details for Academy Island fragment hunt
Academy Island features palm trees, sandy shores, and a tall academy structure with tower-like rooftops. The first fragment is positioned on a tree branch close to the spawn area, while the second fragment is hidden on a high roof structure resembling a tower section of the academy building. Both locations require slight vertical climbing but no combat is necessary to retrieve them.

How to find the first Demonite Fragment on the tree branch
Step 1
Spawn or return to Academy Island after accepting the quest and face the cluster of palm trees near the main sandy area.
Step 2
Look for a tree with a noticeable extended branch positioned slightly above ground level. This branch is accessible with a jump or mobility skill.

Step 3
Jump onto the branch carefully. The fragment does not glow brightly from a distance, so adjust your camera angle downward.
Step 4
You will see the interaction prompt labeled Demonite Fragment – Collect. Press the interact key to pick it up.
Once collected, your quest tracker should update to show 1/2 Demonite Fragments collected.

This first fragment is extremely close to spawn, making it the fastest one to secure.
How to find the second Demonite Fragment on the academy tower roof
Step 1
Move toward the main academy structure visible from most parts of the island.
Step 2
Locate the tower-like roof section of the building. It appears elevated and slightly separate from the lower roof layers.

Step 3
Use your jump, dash, or mobility ability to climb onto the rooftop. If your character has multiple jump capability, this becomes much easier.
Step 4
Search near the edge or flat surface area of the tower roof. The fragment is placed on top and may require slight repositioning of your camera to see clearly.

Step 5
Interact with the fragment and collect it.
After collecting the second fragment, your quest tracker will display 2/2 Demonite Fragments collected, meaning the objective is complete.

How to complete the Demonite Core quest after collecting fragments

Completing the Demonite Core quest efficiently
If your goal is speed, focus on mobility. You should collect the tree fragment first since it is near spawn, then immediately move to the academy tower roof. Avoid unnecessary combat, as no enemies guard these fragments.
Positioning your camera slightly downward when on elevated surfaces helps you spot the interaction prompt faster. Players who already know the jump route can finish this entire quest in under three minutes.
The Demonite Core quest on Academy Island is one of the fastest collectible quests in Sailor Piece. With one fragment placed on a nearby tree branch and the second located on a tower-like roof, you can complete it quickly without combat. If you focus on mobility and follow the exact locations described, you will finish the entire objective smoothly and continue progressing without delay.
