What to know
- Limitless Key drops only from the Gojo boss
- The fight takes place on Shibuya Station Island
- Drop chance is ~36%, so repetition is expected
- The key unlocks after the JJK Update only
If you’re pushing deeper into endgame progression in Sailor Piece, the Limitless Key is a required bottleneck item. Many players struggle not because the fight is hard, but because they farm it inefficiently. The fastest path focuses on cutting downtime, controlling the fight, and repeating attempts as cleanly as possible.
What the Limitless Key is used for
The Limitless Key is a progression-critical item tied to advanced unlocks. Without it, certain abilities, upgrades, or late-game systems remain inaccessible. Because it blocks progress, most players aim to get it as soon as their build can comfortably defeat Gojo.
Unlike quest-based items, this key relies entirely on RNG, making efficiency far more important than difficulty.

Where the Limitless Key drops
The only way to obtain the Limitless Key is by defeating the Gojo boss on Shibuya Station Island. No chests, side quests, or alternative enemies drop it, so all farming strategies revolve around this single encounter.
Quick overview of the farm
| Detail | Information |
|---|---|
| Island | Shibuya Station Island |
| Boss | Gojo |
| Drop item | Limitless Key |
| Drop chance | ~36% per kill |
| Expected kills | 3–5 runs on average |
Because the drop chance is fixed, faster clears and faster resets directly translate to less total grind time.
How to get the Limitless Key fast
The method itself is simple, but speed comes from execution. The goal is to fight Gojo repeatedly with minimal downtime between attempts.
Step 1: Reach Shibuya Station Island efficiently
Before you start farming, make sure your travel route is optimized. Set your spawn or checkpoint as close to Shibuya Station Island as possible. Every extra minute spent traveling adds up quickly across multiple attempts.

Step 2: Defeat the Gojo boss consistently
Gojo is designed to punish reckless play. While burst damage can shorten the fight, consistency matters more than speed.
Focus on:
- Sustained damage rather than risky all-in combos
- Dodging and spacing during heavy attacks
- Abilities that allow safe uptime
A clean, repeatable kill is far faster than dying once and restarting the fight.

Step 3: Reset and repeat without waiting
Since the Limitless Key has only a 36% drop chance, it’s normal to fight Gojo several times. Waiting around for respawns is one of the biggest time sinks.
If respawn timers are long on your server, server hopping after each kill is often the fastest option.

Farming efficiency compared
Small optimizations make a huge difference over multiple runs.
| Farming Approach | Average Time to Key |
|---|---|
| Casual farming, no resets | 45–60 minutes |
| Optimized solo farming | 20–30 minutes |
| Efficient server hopping | 15–25 minutes |
Most players who complain about bad luck are simply spending too much time idle between attempts.
Common mistakes that slow progress
Many runs are wasted due to avoidable issues:
- Waiting for Gojo to respawn instead of switching servers
- Overcommitting to burst and dying mid-fight
- Forgetting to set spawn points near the island
- Entering the fight without sustain or defensive tools
Fixing these alone often cuts total farming time in half.
Is the Limitless Key guaranteed?
There is no pity system, but probability works in your favor. With a 36% drop chance, most players obtain the Limitless Key within a few successful kills. Long dry streaks can happen, but they are uncommon if you keep farming efficiently.
Getting the Limitless Key without wasting time
The Limitless Key grind is less about luck and more about discipline. Treat Gojo as a repeatable farm rather than a one-time boss, and the process becomes much less frustrating. Fast travel, safe kills, and immediate resets are the core principles.
To get the Limitless Key fast, your focus should be simple: Shibuya Station Island, Gojo, repeat efficiently. Expect multiple runs, optimize every reset, and avoid unnecessary downtime. Do it right, and this key becomes a short checkpoint instead of a long grind.
