The Jujutsu ID Card is a Material-tab item in Lineage Piece locked behind a single paid quest chain that runs across two islands. It is also the gate for the Cursed Seal, which only starts dropping once the card is already in your bags. The chain is long, but every stage has a fast route if you know which NPC to talk to.
Quick answer: Pay Abito (I-Card) 10,000 Gems at Shinjuku Showdown, then clear all five quest stages, ending with 15 broken Shrines. After the card drops, breaking more Shrines yields the Cursed Seal.
What you need before starting the Jujutsu ID Card quest
Every objective in the chain is scored off katana or combat damage, so a Devil Fruit or a specialized style will not move the counters. A plain Katana is enough, and it is cheap.
- 10,000 Gems to accept the quest from Abito (I-Card).
- A Katana, sold at Dawnwind Village for 2,500 Coins.
- Teleport access to both Shinjuku Showdown and Jujutsu Highschool.
- Enough damage to handle Curse Spirit [Lv.10k] mobs at the Shrines.
The Gem cost is paid up front when you accept the quest, before any objective is tracked. Do not talk to Abito until you have the Katana ready.
All five Jujutsu ID Card quest objectives
The stages unlock in a fixed order. You cannot skip ahead or bank progress on a later step early, so the sequence below is also your route.
| Stage | Objective | Where |
|---|---|---|
| 1 | Deal 3M damage | Any island |
| 2 | Kill 150 Sorcerer Student | Jujutsu Highschool |
| 3 | Defeat 75 bosses | Jujutsu Highschool |
| 4 | Defeat 35 bosses | Shinjuku Showdown |
| 5 | Break 15 Shrines | Both islands |
Clearing the quest chain stage by stage
Shrine spawns and the 6-minute respawn rule
The final stage asks for 15 broken Shrines, but only eight Shrine spawn points exist, split between Shinjuku Showdown and Jujutsu Highschool. That math is why this step takes longer than the rest of the chain combined.
Interacting with a Shrine does not break it outright. It spawns Curse Spirit [Lv.10k] enemies, and the Shrine only counts once those spirits are cleared. Bring a build that can survive a group fight rather than one tuned for single targets.
Run a full circuit of all eight locations, then wait roughly six minutes for them to respawn and break seven more to reach 15. Hopping servers is not necessary, as the timer runs on its own.
How to confirm the Jujutsu ID Card unlocked
The quest tracker clears itself the moment the fifteenth Shrine breaks, and the reward drops straight into your bags. Open your inventory and switch to the Material tab to see the Jujutsu ID Card listed there. If it is not in that tab, the Shrine count has not finished registering.
Farming the Cursed Seal after the ID Card
The Cursed Seal comes from the exact same Shrines, but it will not appear until the Jujutsu ID Card is already in your inventory. Owning the card effectively changes the Shrine loot pool, so nothing you break before finishing the quest counts toward it.
Keep running the eight-Shrine circuit on both islands and clearing the Curse Spirit packs. Seals drop as you break Shrines, alongside the other cursed materials that come out of Jujutsu Highschool content, and the same six-minute respawn window controls how fast you can cycle.
Since the Shrine route is now your long-term farm, memorize a single loop order across both islands rather than wandering. The respawn timer, not your clear speed, is the real bottleneck.
Once the card is banked, the grind stops being a quest and turns into a repeatable route. Everything after that point is just how many Shrine cycles you are willing to run.
