Fusion Piece just received a major JJK-themed update, adding new characters like Yuji Itadori and the highly anticipated Heian Sukuna. This update brings fresh questlines, new bosses, and some of the strongest abilities currently available in the game. Among them, Heian Sukuna stands out as one of the most powerful specs, offering high damage output and flashy abilities that make it a top-tier choice for both PvE and boss fights. This guide breaks down how to unlock Yuji, how to obtain Heian Sukuna, and what makes these new powers so strong.
How to Get Yuji Itadori in Fusion Piece
To start the JJK content, you first need to travel to Shibuya Island. This is the central location for both Yuji Itadori and Sukuna-related content. Yuji is relatively easy to obtain compared to other characters, but still requires specific items from the new boss.
To unlock Yuji, you need:
- Cursed Fighter title
- Itadori Cursed Bandages
- One Awakened Soul Essence
All of these materials drop from the Yuji boss, which spawns periodically based on server time. Once you collect everything, you can claim Yuji from the NPC and unlock his abilities.
Yuji is not the strongest unit in the game, but he is very accessible and a good starting point for new players entering the JJK update.
How to Unlock Heian Sukuna
Heian Sukuna is the main highlight of this update and requires significantly more effort to obtain. The NPC for Sukuna is located on top of a building in Shibuya Island, but you cannot interact with it immediately.
Before starting the questline, you must prepare several requirements:
- Sukuna V1 unlocked
- “King of Curses” trait equipped
- 400,000 gems
- Sukuna’s Fingers (used at least 25 times)
Sukuna Fingers are obtained from the Sukuna V1 boss. To spawn this boss, you need special materials that drop from enemies tied to Fusion Island content. Once you have enough materials, you can repeatedly summon and farm the boss for progression items.
After meeting all requirements, return to the NPC to begin the Heian Sukuna questline.
Heian Sukuna Questline Requirements
The questline itself is split into three main objectives:
- Defeat 6 Sukuna enemies
- Defeat 10 Naoya enemies
- Defeat 4 Sukuna bosses
Once all tasks are completed, you will be rewarded with Heian Sukuna.
This process is grind-heavy but straightforward, focusing mainly on repeated boss farming and enemy clearing across the Shibuya and Fusion Island areas.
Why Heian Sukuna Is So Strong
Heian Sukuna is widely considered one of the strongest specs currently available in Fusion Piece. His abilities deal massive damage and are especially effective in both group fights and solo grinding. The attack animations are fast, the hitboxes are wide, and the overall scaling makes him a top-tier choice for late-game players.
Even without a perfect build, Heian Sukuna still performs extremely well, which shows how strong his base kit really is. Players who invest in proper stats or gear will see even higher damage output.
The JJK update in Fusion Piece adds a solid mix of grind-based unlocks and high-impact abilities. Yuji serves as an easy entry point, while Heian Sukuna represents the true endgame reward for dedicated players. With strong damage scaling and smooth animations, Sukuna currently sits at the top of the meta for many players. If you are working through the update, prioritizing Sukuna progression is easily the best long-term goal.
