Sailor Piece Black Reaper is a Kaneki-inspired melee fighting style you buy from the Buy Black Reaper NPC on Isolation Island in Sea 2. It costs 65,000 Gems, 20 Black Shards, 12 Reaper Remnants, five Rinkaku Cores, two Ghoul Essences and the One Eyed King title. You’ll earn the materials and title from the Black Reaper Boss, which requires Reaper Keys to summon.
You won’t get the style from a lucky boss drop. The boss supplies the materials, but the seller handles the purchase. After that, you’ll need 25 more qualifying boss defeats, the Ghoul bloodline and 250 mastery to unlock the F move. Here’s how to get everything without spending Reaper Keys on the wrong difficulty.
How to get Sailor Piece Black Reaper
If you’re starting the Sailor Piece Black Reaper grind from scratch, here’s the order to follow:
- Unlock Sea 2, then complete the six Blood Flowers quest to access Isolation Island.
- Defeat Level 18,500 Ghoul Members to collect Reaper Keys.
- Inside Isolation Island’s large chamber, use the Black Reaper Summoner to start the boss fight.
- Farm the boss for One Eyed King and the four required materials.
- Find Buy Black Reaper on a wall platform beside the chamber and pay the materials plus 65,000 Gems.
From the Isolation Island teleport, head to the huge central chamber. The summoner is inside. For the Sailor Piece Black Reaper seller, jump onto the chamber roof, turn right and look for the platform set into the wall. The Black Reaper Master stands on the roof itself. They’re separate NPCs, so don’t confuse buying the style with claiming its F move.
Sailor Piece Black Reaper: Isolation Island location
You need Sea 2 access first. That requires Level 12,500, Ascension 5, two Ancient Fragments and seven Map Pieces. Our Sailor Piece Sea 2 unlock walkthrough covers the route. Once you’re in Sea 2, start the Blood Flower quest from the NPC on the tall right-hand mountain of Sea 2 Starter Island.
The flowers are red pickups, and you can collect them in any order. Most are tucked behind buildings or against rocks, so stay close to the ground while searching. Follow the landmarks below, then return to the quest giver when the tracker reads 6/6 to unlock Isolation Island.
| Island | Blood Flower location |
|---|---|
| Sea 2 Starter Island | Head left from the spawn crystal and find the high ledge between the mountain peaks. |
| Bizarre Island | From the colosseum boss summoner, climb behind the structure into the gap between two tall mountains. |
| Punch Island | From the left-side quest giver, climb the opposite ridge and search behind the building near the mountain. |
| World Island 2 | Look at the great tree beside the Spec Passive or Power NPC and check behind its base by the shoreline. |
| Slayer Island | Near Sun God’s area, pass through the narrow gap to the right and check behind the tree against the rock wall. |
| Blue Planet | Near the Empyrean (Goku) trainer, search the raised mountain recess behind the arena. |
If the teleport hasn’t appeared, make sure you’ve handed in the Blood Flower quest. Another player taking a flower shouldn’t prevent you from collecting your own. Once the island is open, the repeatable Ghoul Member quest starts at Level 18,500. Our Sea 2 levelling guide covers that bracket, while the Sea 1 route helps if you’re not at the required level yet.
How to farm Reaper Keys on Isolation Island
Reaper Keys drop from Ghoul Members on Isolation Island. Current community tracking records a base drop rate of 0.0955%, often rounded to 0.1%. That makes this a long mob farm, with no guaranteed key after any fixed number of kills. Other Sea 2 enemies aren’t documented as Reaper Key sources.
For the Sailor Piece Black Reaper key farm, stick to Ghoul Members you can defeat quickly without dying. Their quest pays EXP and Gems, but isn’t required for the key drop. The 0.0955% figure is a reported base rate, not a guaranteed key after a thousand kills. If nothing is dropping on an old server, try joining a fresh one; the keys were affected by an earlier update bug.
Keep keys for the Sailor Piece Black Reaper mastery quest, too. It requires 25 boss defeats on Medium or higher. Medium costs two Reaper Keys, so those fights require at least 50 keys, assuming you win every attempt. That’s in addition to any spent collecting the purchase materials and title.
Sailor Piece Black Reaper Boss summon costs
Visit the Black Reaper Summoner inside Isolation Island’s main chamber. Select Normal, Medium, Hard or Extreme. Each step up costs an additional key, but offers better reported rare-drop chances. The boss’s HP also climbs steeply, so choose a difficulty you can actually defeat.
| Difficulty | Reaper Keys | Boss HP (approx.) | One Eyed King chance |
|---|---|---|---|
| Normal | 1 | About 50B HP | 0.75% |
| Medium | 2 | About 100B HP | 0.90% |
| Hard | 3 | About 300B HP | 1.15% |
| Extreme | 4 | About 800B HP | 1.40% |
The One Eyed King title is a requirement for Sailor Piece Black Reaper. Community records list a 125-defeat pity and a +110% damage bonus. The pity applies to the title only, not to Black Shards, Ghoul Essence or any other item. You can get the title before that many kills, but you may have to farm the boss for quite a while.
Black Reaper boss drops at every difficulty
The materials needed for Sailor Piece Black Reaper come directly from its summoned boss. These are the community-reported base chances for all four difficulties. Ghoul Outfit and Ghoul Aura are additional cosmetics, not items you must buy for the fighting style.
| Drop | Required | Normal | Medium | Hard | Extreme |
|---|---|---|---|---|---|
| Black Shard | 20 | 5% | 6.25% | 8% | 10% |
| Reaper Remnant | 12 | 1.75% | 2% | 2.5% | 3.25% |
| Rinkaku Core | 5 | 0.475% | 0.55% | 0.7% | 1% |
| Ghoul Essence | 2 | 0.19% | 0.225% | 0.3% | 0.45% |
| Ghoul Outfit | Optional | 0.3% | 0.45% | 0.6% | 0.75% |
| Ghoul Aura | Optional | 0.05% | 0.065% | 0.08% | 0.115% |
Ghoul Essence and Rinkaku Core have the lowest listed chances among the materials for Sailor Piece Black Reaper. Extreme improves the odds but costs four keys and has roughly 800 billion HP. Medium costs two keys and can also count towards F-move mastery. Choose the highest difficulty you can clear reliably, not simply the one with the best percentage.
Where to buy Sailor Piece Black Reaper
For the Sailor Piece Black Reaper purchase, bring One Eyed King, 65,000 Gems, 20 Black Shards, 12 Reaper Remnants, five Rinkaku Cores and two Ghoul Essences to the wall-platform seller. Select the purchase option. A boss defeat only awards drops and title chances; it doesn’t put the style into your inventory automatically.
Earn the 65,000 Gems through quests, defeated enemies and chests. For separate shards, crates and other rewards, check our Sailor Piece codes guide. The Sailor Piece bosses reference can help if you’re also farming other summon materials.
Sailor Piece Black Reaper F move: Mastery quest
When you first obtain Sailor Piece Black Reaper, the M1, Z, X, C and V moves are available, but the F move is locked. Speak to Black Reaper Master on top of Isolation Island’s central chamber to begin the separate mastery quest.
- Defeat 25 Black Reaper bosses on Medium difficulty or higher. Normal kills don’t count.
- Obtain and equip the Ghoul bloodline. Use Bloodline Stones and rerolls if needed, then check the active bloodline before continuing.
- Reach 250 mastery with Black Reaper equipped.
When all three objectives are complete, return to the Black Reaper Master to claim F and the 30% Black Reaper damage bonus. It’s separate from the One Eyed King title’s effect. If F shows up on the hotbar but won’t work, check the mastery tracker: earlier players reported an icon that looked unlocked before the quest was finished.
Is Sailor Piece Black Reaper worth the grind?
The Sailor Piece Black Reaper moveset is built around wide attacks and multi-hit strikes. Here’s what each button does:
The Sailor Piece Black Reaper style is a major grind: rare keys, four materials, a title and 25 higher-difficulty fights for the mastered F move. If you’re already progressing through Sea 2, its broad attacks can be worth that effort. If normal quest enemies are still difficult, build up your damage first. For another high-level materials farm, see our Sailor Piece Luffy Boss guide.
| Move | Effect | How to unlock |
|---|---|---|
| M1 | Basic melee combo | After purchase |
| Z | Leap and strike repeatedly in front of you | After purchase |
| X | Jump and slam down with a red impact | After purchase |
| C | Tentacle slashes followed by a burst | After purchase |
| V | Create a damaging red area around nearby enemies | After purchase |
| F | Spinning tentacle attacks ending in a forward plunge | Black Reaper Mastery |
Can you buy Sailor Piece Black Reaper with Robux?
