In this guide, I have shared how to get Black Reaper (Kaneki) in Sailor Piece and unlock its F Move.
How to Get Black Reaper (Kaneki) in Sailor Piece
Black Reaper (Kaneki) is a high-tier fighting style in Sailor Piece that you can unlock through Isolation Island in Sea 2. To obtain it, you must collect several rare materials, defeat bosses, and also hold a special title. Once everything is ready, you can trade with the Black Reaper Seller NPC to unlock the spec.
To start the process, head to Isolation Island (you must complete the blood flowers questline to unlock this island]. If you have already reached this area, you’re already close to unlocking Kaneki’s Black Reaper form. From the main teleport portal, move into the large chamber area where key NPCs are located. The Black Reaper Seller NPC is hidden inside the wall platform on the right side, while the Black Reaper Mastery NPC is at the top center of the chamber.
Speak to the Black Reaper Seller NPC only after collecting all required materials. He will then unlock the Black Reaper fighting style for you.
Requirements to Unlock Black Reaper:
- One-Eyed King (Title)
- 65,000 Gems
- 20x Black Shards
- 12x Reaper Remnants
- 5x Rinkaku Cores
- 2x Ghoul Essences
How to Get the Required Materials
Gems (65,000)
- Redeem game codes regularly
- Complete repeatable island quests from NPCs
- Open chests earned from quests and exploration
- Defeat mobs and bosses for random gem drops
Boss Drop Materials
- Black Shards – Dropped from Black Reaper Boss (5%–10% chance depending on difficulty)
- Reaper Remnants – Dropped from Black Reaper Boss (1.75%–3.25% chance)
- Rinkaku Cores – Dropped from Black Reaper Boss (0.48%–1% chance)
- Ghoul Essences – Dropped from Black Reaper Boss (0.19%–0.45% chance)
- One Eyed King Title – Rare drop from Black Reaper Boss (0.75%–1.4% chance, 125 pity system)
Once all items are collected, return to the Black Reaper Seller NPC at Isolation Island. After trading, you will unlock Black Reaper, but only basic moves (M1, Z, X, C, V) will be available initially. The final ability (F move) must be unlocked separately through mastery progression.
How to Unlock Black Reaper F Move
To unlock the F move, you must complete the Black Reaper Mastery questline. Start it by speaking to the Black Reaper Mastery NPC at the top of the Isolation Island chamber.
- Complete Mastery Requirements:
- Defeat Black Reaper Boss 25 times (medium difficulty)
- Obtain Ghoul Bloodline
- Reach Level 250 Mastery with Black Reaper
- After finishing all tasks, you will unlock the F move and also receive a +30% damage boost for all Black Reaper abilities.
Where to Find the Black Reaper Boss in Sailor Piece
The Black Reaper Boss is not found naturally—it must be summoned on Isolation Island. Go inside the main chamber and find the Black Reaper Summoner NPC. Interact with him once you have enough Reaper Keys to spawn the boss.
- Boss Drops:
- One Eyed King Title (up to 1.4% chance, 125 pity)
- Ghoul Outfit accessory (up to 0.75%)
- Black Shards (up to 10%)
- Reaper Remnants (up to 3.25%)
- Rinkaku Cores (up to 1%)
- Ghoul Essences (up to 0.45%)
- Ghoul Aura (very rare, 0.05%–0.115%)
How to Get Reaper Keys
Reaper Keys are required to summon the Black Reaper Boss. These are dropped by Ghoul Member mobs located on Isolation Island.
- Drop chance: around 0.1% per Ghoul Member
- Higher difficulties require more keys to summon the boss
Reaper Key Requirements by Difficulty
- Normal – 1 Reaper Key
- Medium – 2 Reaper Keys
- Hard – 3 Reaper Keys
- Extreme – 4 Reaper Keys
Once you gather enough keys and defeat the boss repeatedly, you’ll be able to fully farm materials and complete the entire Black Reaper unlock path in Sailor Piece.
