Unlocking Sukuna V1 and Strongest in History V2 in Sailor Piece

Sukuna is one of the most aggressive melee fighting styles in Sailor Piece, offering high AOE damage and strong PvP potential. It comes in two versions — Sukuna V1 and its upgraded form, Sukuna V2 (officially called Strongest in History). V2 deals more damage and has a wider AOE, but getting there requires significantly more farming. Here's exactly what each version demands and how to finish the grind efficiently.

Quick answer: Sukuna V1 requires completing a three-part questline at Shibuya Station and turning in boss-drop materials plus 5,000 Gems and 1.25M Gold. Sukuna V2 skips the questline entirely but needs rare drops from the Strongest in History boss on Shinjuku Island, including the Disgraced One title and 20 eaten Awakened Cursed Fingers.

Sukuna V1 Questline and Requirements

Head to Shibuya Station and find the Sukuna Trainer NPC on the upper platform. Speaking to this NPC starts a three-quest chain that must be completed before you can hand in any materials.

Step 1: Deal a cumulative total of 35 million damage. Farming high-HP NPCs or repeatedly fighting bosses is the fastest way to rack this up. Any damage source counts.

Step 2: Defeat 25 players. You can do this in public servers through normal PvP, or use a private server with an alt account or a willing friend to speed things along.

Step 3: Defeat the Sukuna boss 15 times. This boss spawns at Shibuya Station automatically — no summoning item needed. It has 5 million HP and respawns on a timer, so with a solid build, you can clear it quickly each cycle.

After finishing all three quests, return to the Sukuna Trainer NPC and submit the following materials to unlock V1.

Because the questline already requires 15 Sukuna boss kills, you'll likely accumulate most of the Cursed Fingers and Dismantle Fangs naturally. The Crimson Heart at 2.5% is the bottleneck — expect to need additional kills beyond the quest minimum to land one. Gold and Gems come from standard NPC farming, chest opening, and redeeming active codes through the game's code redemption system.

Sukuna Boss Full Drop Table

Since you'll be farming the Sukuna boss heavily for both V1 materials and the key item needed to access V2, knowing the complete loot pool helps you plan.

The Malevolent Key at 30% is critical — it's the only way to summon the Strongest in History boss required for V2. Hold onto every key you get.

Sukuna V2 (Strongest in History) Requirements

Sukuna V2 is a separate, more powerful melee spec. Unlike V1, there is no questline to complete. You simply need to collect all the required materials and bring them to the Strongest in History Trainer NPC, located on the rooftop of Shinjuku Island.

Note that the Awakened Cursed Fingers must be consumed (eaten), not just held in your inventory. The Disgraced One title also doubles as a 50% damage boost, making it useful well beyond the unlock requirement. Cursed Flesh is by far the rarest drop at under 1%, so expect a long grind.

Spawning and Fighting the Strongest in History Boss

Unlike the Sukuna boss, the Strongest in History boss does not auto-spawn. You need to use a Malevolent Key at the Strongest Boss Summoner on Shinjuku Island. Each key is consumed on use, so every attempt costs one key — and keys only drop from the Sukuna boss at a 30% rate.

The boss has multiple difficulty tiers. On Easy, it starts with 150 million HP. On Extreme, that jumps to 2.5 billion HP. Higher difficulties improve drop rates across the board, so running Extreme is strongly recommended if your build can handle it. Make sure you have your best Devil Fruit, accessories, sword, and runes equipped before starting the fight.

The full drop table for this boss includes one additional notable item beyond the V2 materials.

Farming Strategy for Both Versions

The two unlock paths are connected. You need to farm the Sukuna boss at Shibuya Station first regardless of which version you're targeting, because V1 requires its drops directly and V2 requires Malevolent Keys that only come from the same boss. A practical approach looks like this:

Step 1: Start the V1 questline at the Sukuna Trainer NPC to begin tracking your 35M damage, 25 player kills, and 15 boss kills simultaneously. Work on damage and player kills between boss respawns.

Step 2: Kill the Sukuna boss repeatedly. Collect V1 materials (Dismantle Fangs, Crimson Heart, Cursed Fingers) and stockpile every Malevolent Key that drops. With 15 required kills and a 30% key drop rate, you should average around 4–5 keys from the quest alone.

Step 3: Once V1 is unlocked, continue farming the Sukuna boss purely for Malevolent Keys. You'll need many keys for V2, since each Strongest in History boss summon consumes one and the rare drops may take dozens of attempts.

Step 4: Use Malevolent Keys at the Strongest Boss Summoner on Shinjuku Island. Run the highest difficulty you can reliably clear. Eat every Awakened Cursed Finger as it drops rather than saving them — you need 20 consumed total.

Step 5: Once you have all materials and the Disgraced One title, return to the Strongest in History Trainer NPC on the Shinjuku Island rooftop to claim V2.

V1 vs. V2 — Is the Extra Grind Worth It?

Sukuna V2 outperforms V1 in both raw damage output and AOE coverage. It's one of the few fighting styles in Sailor Piece that can comfortably handle the Shadow Monarch boss, which is tied to some of the best swords in the game. If you're focused on endgame PvE or competitive PvP, V2 is the clear upgrade. The tradeoff is a significantly longer farm, especially for Cursed Flesh and the Disgraced One title, both sitting below 3% drop rates even on Extreme difficulty.

For players still building up their gear and stats, V1 serves as a strong stepping stone. It's accessible much earlier and the Sukuna boss is easy enough to defeat with a mid-tier build. You can always pursue V2 later once your loadout is strong enough to handle the Strongest in History boss efficiently.
