All Hidden NPC Locations and Rewards in Jujutsu Zero

1. Summer Island NPC - 10 Summer Crates

The first hidden NPC is on a mountain on Summer Island. Climb the gray mountain until you reach the NPC named Haiden Seek.

Talk to the NPC to claim 10 Summer Crates for free. This is the quickest reward in the route, so collect it before leaving Summer Island.

Summer Island map route

Open the Summer Island map and use the player-arrow position in the screenshot as your destination. The arrow points to the gray mountain on the western side of the island.

2. Physical Restriction mountain NPC - 10,000 Lumens

The second Haiden Seek NPC is on a mountain near the Physical Restriction area. Look for the narrow space where the gray stone wall meets the tall green wall.

Talk to this NPC to receive 10,000 Lumens for free.

Map route to the second NPC

Use the player arrow on the far western mountain edge in the map screenshot. Travel toward that edge from the Physical Restriction area, climb to the marked height, and check the corner where stone meets the green wall.

3. Offense Trainer stone NPC - missing-hat quest

The third Haiden Seek NPC stands on top of a high stone near the Offense Trainer. Climb to the top of the stone and speak to the NPC to start the hidden quest.

The quest asks you to find the NPC's hat. After accepting it, a marker appears on your map, so follow the marker instead of searching the entire world.

Map route to the third NPC

Use the player arrow in the map screenshot as the exact position of the tall stone. The Offense Trainer area is your main landmark; once you reach it, look upward and climb onto the highest stone.

Find Haiden's hat and claim the quest reward

Follow the quest marker to HaidenHat. The item is tucked beneath a large rock platform, as shown in the screenshot, so check under the rock instead of only searching the top.

Collect the hat to complete the quest and receive 20,000 Lumens and 1 Zenin Emblem.

4. Shadow Island tree NPC - Divine Essence exchange

The final hidden NPC is the ??? Exchange NPC on Shadow Island. It is inside the large tree, so climb onto the tree and enter the green interior to find it.

You can exchange 50 Shadow Essence and 2,500 Cursed Crystals for 1 Divine Essence. After collecting 2 Divine Essence, you can use them to summon the special boss inside the cave on Shadow Island.

Shadow Island map route

The player arrow in the map screenshot marks the large tree that contains the ??? Exchange NPC. Use the named teleport points and nearby landmarks to reach the lower-left side of the tree canopy, then climb into the interior.

Before starting the exchange, check that you have 50 Shadow Essence and 2,500 Cursed Crystals.
