The Crimson Heart is a Mythical-rarity item in Sailor Piece and the key ingredient needed to unlock the Sukuna Melee Spec, currently one of the strongest combat styles in the game. It drops exclusively from the Sukuna boss at Shibuya Station, with a brutal 2.5% drop rate. Below is everything you need to know to farm it efficiently and put it to use.
| Detail | Info |
|---|---|
| Item Rarity | Mythical |
| Drop Source | Sukuna Boss |
| Location | Shibuya Station |
| Drop Chance | 2.5% |
| Boss Spawn Timer | Every 7 min 30 sec |
| Boss HP | 5,000,000 |
| Used For | Sukuna Melee Spec (Curse King) |
Teleport to Shibuya Station using any island dock portal. This is the most productive island in the game, home to three auto-spawning open-world bosses: Yuji, Gojo, and Sukuna all on roughly 5–7.5-minute timers.
Wait at the spawn point for Sukuna to appear. A map marker and countdown timer display on-screen before each spawn, so you won’t miss it. Sukuna has 5 million HP, but players with a mid-to-late-game build can clear him without much difficulty. The short respawn timer makes this one of the most efficient farms in Sailor Piece.
The Crimson Heart has a 2.5% drop chance, the rarest item Sukuna drops. Expect to run the boss many times before it appears. The good news: all other materials needed for the Sukuna Spec also drop from the same boss, so your runs are never wasted.
| Item | Drop Chance |
|---|---|
| Haki Color Reroll | 60% |
| Race Reroll | 40% |
| Trait Reroll | 32.5% |
| Malevolent Key | 30% |
| Boss Ticket | 30% |
| Dungeon Key | 20% |
| Cursed Finger | 20% |
| Dismantle Fang | 8% |
| Sukuna Collar | 4% |
| Curse King Title | 4% |
| Crimson Heart | 2.5% |
Once you have the Crimson Heart, go to Shibuya Station and speak to the Sukuna Trainer NPC (also called the Curse King Trainer). Before the quests unlock, you must first hand over these materials:
All three item types drop from Sukuna, so your farming runs cover everything at once.
After submitting materials, you’ll receive three quests to complete:
The Crimson Heart grind is brutal, but the Sukuna Melee Spec (Curse King) is among the strongest specs in Sailor Piece. Key damage values:
This mix of raw damage and built-in survivability makes it a top pick for both PvP and boss farming. For a full breakdown of the best builds in the game, check our Sailor Piece Tier List and Sailor Piece Bosses Guide.
The Crimson Heart has a 2.5% drop chance from the Sukuna boss — the rarest item he drops, even rarer than the Sukuna Collar and Curse King Title (both at 4%).
Sukuna spawns automatically at Shibuya Station every 7 minutes and 30 seconds. A map timer alerts you before each spawn.
No. You only need one Crimson Heart to unlock the Sukuna Melee Spec. Any extras can be traded to other players.
Sukuna also drops Malevolent Keys (30%), Cursed Fingers (20%), Dismantle Fangs (8%), and reroll items. All of these except rerolls are used directly in unlocking the Sukuna Spec.
Yes. Equip the Fortune Rune and use the Kitsune race for a combined luck bonus that improves rare drop rates. There is no guaranteed method to force the drop, consistent farming is the only path.
