With the level cap now raised to 8,000, this update focuses heavily on endgame progression and boss farming. This guide explains where to go, how to unlock Gojo V2 and Sukuna V2, and what you need to prepare before fighting the new bosses. Also check out our Sailor Piece Codes for more rewards!
Shinjuku Showdown Island Location
The new content takes place on Shinjuku Showdown Island, which is the main hub for this update. This island includes:
- New quests
- Boss spawners for Gojo and Sukuna V2
- Seller NPCs for unlocking the new characters
Both bosses are summoned through special keys instead of normal spawning.
How to Spawn Gojo and Sukuna V2
To fight the new bosses, you must collect special keys dropped by the V1 versions of the characters in Shabuya.
Boss key requirements:
- Gojo V2: 2 Limitless Keys
- Sukuna V2: 2 Malevolent Keys
You can farm these keys by repeatedly defeating the V1 Gojo and Sukuna bosses. Once you have enough keys, return to Shinjuku Showdown Island and use the boss spawners.
Requirements to Unlock Gojo V2
To unlock Gojo V2 (The Strongest of Today), you must gather the following materials:
- 6 Six Eyes (eaten)
- 9 Reversal Pulse
- 3 Blue Singularities
- Infinity Essences
- The Strongest Sorcerer title
All of these items drop from the new Gojo boss. After collecting them, visit the seller NPC located on top of the buildings on the island.
Requirements to Unlock Sukuna V2
For Sukuna V2 (The Strongest in History), you need:
- 20 Awakened Cursed Fingers (eaten)
- 7 Vessel Rings
- 3 Malevolent Souls
- 1 Cursed Flesh
- The Disgraced One title
These materials are obtained from the Sukuna V2 boss. Like Gojo, you must exchange them with the seller NPC to unlock the character.
How to Unlock Domain Expansions
After unlocking the characters, you still need to activate their Domain Expansion (F move). This requires crafting special domain shards.
Sukuna Domain Unlock
To craft the Shrine Domain Shard, you need:
- 6 Cursed Talismans
- 2 Infinity Essence
You must also have the Mythical Malevolent Trait. Once crafted, go inside the building on the island to unlock Sukuna’s domain.
Gojo Domain Unlock
To craft the Infinity Domain Shard, you need:
- 6 Energy Shards
- 2 Cursed Flesh
You must also have the Mythical Infinity Trait. After crafting, enter the building to unlock Gojo’s domain ability.
Gojo V2 vs Sukuna V2: Which Is Better?
Both characters have strong move sets and flashy skills, but Sukuna V2 currently stands out for boss farming. His cooldowns are shorter, his range is wider, and he benefits heavily from invincibility frames. This makes him extremely effective for grinding difficult bosses. Gojo V2 still offers a solid kit and strong burst damage, making him a good choice for players who prefer balanced combat.
The Shinjuku Showdown update adds a deep grind loop centered around boss farming, rare materials, and powerful domain abilities. Unlocking Gojo V2 and Sukuna V2 takes time, but both characters are strong additions to any late-game build. Focus on farming keys efficiently, gather materials in groups when possible, and prioritize Sukuna if your goal is faster boss clears.
