Shadow Island is the new area tied to the Ten Shadows Part 1 update in Jujutsu Zero, and you cannot set foot on it without the Secret Ticket. The ticket is your key to the Shikigami Altar, where the entire Ten Shadows progression begins. Because it is rare and the way you get it may change after launch, the smart move is to farm one in advance.
Quick answer: Defeat Periodic Overworld Bosses during the Summer Event until one drops the Secret Ticket (roughly a 0.5% drop chance), then carry it into the Ten Shadows update to unlock entry to Shadow Island.
What the Secret Ticket unlocks in Jujutsu Zero
The Secret Ticket is a single-purpose access item. It lets you enter Shadow Island, and Shadow Island is where the Shikigami Altar lives. Without the ticket, the area is closed to you, which means the Ten Shadows Cursed Technique stays locked as well.
Once you are on the island, the altar becomes the center of your progression. You summon Shikigami there, fight them, and add each one to your collection by winning. That first step depends entirely on holding the ticket.
How to farm the Secret Ticket fast
The ticket currently drops from Periodic Overworld Bosses that spawn during the Summer Event. These bosses appear at intervals across the world, and beating them gives a chance at the ticket as a reward.
The catch is the drop rate. The Secret Ticket sits at about a 0.5% chance, which makes it one of the rarest event drops right now. Expect to clear a large number of bosses before one appears, so start early rather than waiting until the update is live.
Tip: Because the current drop method may not exist after the Ten Shadows update goes live, securing at least one ticket now is the safest preparation. You know it worked when the Secret Ticket appears in your inventory after a boss kill.
How Shadow Island and the Ten Shadows system work
Ten Shadows does not level up like other Cursed Techniques. There is no shared mastery bar that unlocks new moves. Instead, each Shikigami is a separate companion you must summon at the Shikigami Altar, defeat in battle, and then tame to keep permanently.
Summoning is not fully random. The altar asks for different crafting materials, and the mix you offer influences which Shikigami is more likely to appear. Dumping every material you own into the altar will not reliably give you the one you want, so it pays to test different combinations.
Every Shikigami also has its own independent skill tree. You strengthen each one on its own, unlocking upgrades and improving abilities per companion rather than boosting Ten Shadows as a whole. Fully maximizing the technique means developing several Shikigami over time.
To feed the altar, the update adds a new overworld raid featuring Crow and Shirou. These raids are one of the main sources of the materials the altar needs, so running them regularly keeps your summoning supplies stocked.
All confirmed Shikigami in Ten Shadows Part 1
The first version of the update ships with four Shikigami, each filling a different combat role.
| Shikigami | Role |
|---|---|
| Nue | Flying Shikigami for offense and utility; also the game’s first flying mount for faster traversal |
| Rabbits | Sustained damage and offensive support during battles |
| Divine Wolves | Offense-focused, built for consistent damage against enemies and bosses |
| Mahoraga | Top of the progression and expected to be the strongest summon; needs far more preparation to unlock |
Launch event rewards worth logging in for
Farming the ticket is only half the prep. The live release event hands out limited-time rewards to players who are online when Ten Shadows goes live.
- Special Crates packed with free rewards.
- An exclusive Cursed Emblem available only during the launch window.
- A server-wide Raid Boss that rewards everyone who takes part.
- Crate Rain events that scatter free loot across the map for a short time.
These only appear during the launch celebration, so they are worth grabbing even if you do not plan to grind right away.

How to redeem codes
The best preparation is straightforward. Grind Periodic Overworld Bosses until you own at least one Secret Ticket, hold onto any crafting materials you pick up, and be ready to log in the moment Ten Shadows launches. Do that and you can walk onto Shadow Island, join the launch event, and start taming Shikigami without waiting.
