Sailor Piece’s newest update introduces one of the most visually impressive and high-damage specs yet—Kokushibo. Built around massive burst damage, stylish animations, and a powerful mastery upgrade, this spec is already looking like a top-tier option for endgame players.
The best part? Unlike some previous grinds, this one is surprisingly straightforward if you follow the right route.
Here’s exactly how to unlock Kokushibo, get its F move, and whether it’s actually worth using.
How To Get Kokushibo in Sailor Piece
Kokushibo is a new melee/spec style focused on:
- Extremely high burst damage
- Strong boss-killing potential
- Clean visual effects (moon-based attacks)
It’s essentially a boss shredder build, similar to Moon Slayer—but pushed even further.
Step 1: Farm Upper Seals (Lawless Island)
Everything starts here.
How to get Upper Seals:
- Kill any NPC
- Stronger enemies = better drop chance
- Can AFK farm efficiently
Tip:
You’ll need a LOT:
- For boss summons
- For F move later
Farming 200–300 early saves time.
Step 2: Farm Moon Slayer Boss (Boss Island)
Once you have seals:
Boss Requirements:
- 1 Upper Seal
- Gems
What you get:
- Six-Eyed Demon Title
- Moon Crest
- Crescent Shards
- Other crafting materials
Six-Eyed Demon Title (Must-Have)
This is required AND insanely strong.
Stats:
- +85% Damage
This alone makes your build significantly stronger.
Step 3: Unlock Kokushibo Spec
Go to Boss Island → Kokushibo NPC
Requirements:
- Six-Eyed Demon Title
- Gems
- Moon Crest
- Boss materials
All materials come from the Moon Slayer boss.
Step 4: Unlock Kokushibo F Move
To fully complete the spec:
Find the Mastery NPC (Boss Island)

This clan is extremely strong and required for full mastery.
