Where the Gryphon Sword is located in Sailor Piece
The Gryphon Sword is purchased from a special NPC located on Shibuya Station Island. This island was introduced with newer updates and contains several NPCs tied to weapon upgrades and new content.

When you arrive at the island, you will need to explore until you locate the Shanks NPC, often referred to as the Gryphon Seller. Interacting with this NPC will open a purchase window that allows you to obtain the weapon once you meet the currency requirements.
Unlike boss drop weapons, there is no RNG involved here, which means you can guarantee the weapon as long as you have the required resources ready. This makes it one of the more reliable late-game sword unlocks for players progressing through the newer content.
How to unlock the Gryphon Sword in Sailor Piece
Step #1 – Travel to Shibuya Island
Your first objective is reaching Shibuya Island, which is where the Gryphon Sword seller is located. Depending on your progression, you may already have this island unlocked through the main progression path.

Once you arrive at the island, move through the area and look for NPCs positioned around the main structures or streets.
Step #2 – Find the Gryphon (Shanks) NPC
Locate the NPC that represents Shanks, also known as the Gryphon Seller. This NPC is responsible for selling the Gryphon Sword.

Approach the NPC and interact with them to open the weapon purchase interface. If you have the required materials, the option to buy the sword will be available.
Step #3 – Pay the currency requirements
To obtain the Gryphon Sword, you must pay the following cost:
| Requirement | Amount |
|---|---|
| Gold | 650,000 |
| Gems | 650 |
Once the payment is completed, the Gryphon Sword will automatically be added to your inventory and can be equipped immediately.

According to update information and guides covering the Alter update content, the sword is obtained directly through this purchase method without additional quests or boss drops. (Source: MrGuider – Sailor Piece Alter Update guide)
Why the Gryphon Sword is a good weapon
The Gryphon Sword stands out because it offers a strong sword option without the frustration of farming boss drops repeatedly. Many powerful weapons in Sailor Piece rely heavily on RNG from boss fights or dungeon rewards, which can take a long time to obtain.
With the Gryphon Sword, the only real challenge is collecting enough gold and gems. If you are actively grinding bosses, completing dungeons, or participating in events, gathering these currencies becomes manageable.

Another advantage is that the sword fits well into sword-focused stat builds, making it especially useful for players who prefer melee combat rather than fruit or ability-heavy builds.
Because it was introduced alongside new content in the Alter update, the weapon is designed to remain relevant for mid-to-late game progression, giving players a strong tool while preparing for tougher bosses and islands.
Tips for farming the Gryphon Sword requirements faster
The biggest barrier to obtaining the Gryphon Sword is the cost, especially the large gold requirement. Players typically farm bosses, dungeons, and repeatable activities to gather currency faster.

Grinding bosses on newer islands is usually the most efficient way to earn money while also collecting other materials. Meanwhile, gems are commonly obtained from bosses, quests, and event rewards, so consistently completing available activities will help you build up the required amount over time.
If you focus on high-level farming routes and repeatable bosses, reaching the 650,000 gold requirement becomes significantly easier compared to relying on small quest rewards alone.
