The True Aizen Sword is the most powerful weapon in Sailor Piece as of the Huge Update (March 10, 2026). It’s a Mythical-rarity endgame sword radiating a signature violet-purple aura, with devastating AoE moves and low cooldowns. Here’s a quick overview before we break down every step:
| Requirement | Details |
|---|---|
| Minimum Level | 8,500+ |
| Cost | 35,000 Gems + 75 Chrysalis Sigils + boss drops |
| Location | True Aizen NPC, Soul Society Island |
| Prerequisite Sword | Aizen Sword (V1) |
| F-Move Unlock | Separate Mastery quest chain |
Before chasing True Aizen, you need the base Aizen Sword in your inventory. Head to Hueco Mundo Island and find the Aizen Trainer NPC near the domed building. Complete his five sequential quests:
After finishing all five, return to the Aizen NPC. Purchase the Aizen Sword using: Mirage Pendant, Illusion Prism, Reiatsu Core, and Hogyoku Fragment — all boss drops from the Aizen enemy.
Soul Society is where True Aizen lives. To unlock it, find the Gin Ichimaru-like Hogyoku Quest NPC at the left edge of Hueco Mundo Island (behind the giant furnaces). You must be Level 8,500+ to accept.
Collect 6 Hogyoku Fragments scattered across multiple islands:
| # | Location | Notes |
|---|---|---|
| 1 | Hueco Mundo | Near Aizen boss spawn, climb left pipe structure |
| 2 | Hueco Mundo | Second fragment on the same island |
| 3 | Shibuya Station | Search the station area |
| 4 | Shinjuku Island | Climb ruined building, stone structure on left |
| 5 | Slime Island | On a tree branch past the Slime Warriors |
| 6 | Judgement Island | Right side of spawn point |
Submit all 6 to the NPC. The Soul Society portal is now open.
On Soul Society Island, Quincy enemies drop Chrysalis Sigils (Legendary rarity). Farm these — you’ll need a lot:
Take your Chrysalis Sigils to the True Aizen Summoner NPC on Soul Society to spawn the boss. Costs per summon:
| Difficulty | Sigils | Boss HP |
|---|---|---|
| Normal | 1 | 850,000,000 |
| Hard | 3 | 7,500,000,256 |
| Extreme | 4 | Higher |
Defeat the boss repeatedly to collect required drops: Evolution Fragment, Divinity Essence, Transcendent Core, and Fusion Ring. Use Normal difficulty if your damage output is modest.
The True Aizen NPC is located directly behind the Soul Society boss spawn. Exchange the following to receive your sword:
Your base Aizen Sword is not consumed — it’s a requirement, not a crafting material.
The F-Move is locked by default. Find the True Aizen F Master NPC on the roof of the tallest building on Soul Society Island. Complete three sequential Mastery quests:
Reward: The F-Move triggers a cutscene summoning a bone-like dragon, plus a permanent 30% damage boost to the entire sword.

| Move | Type | Highlight |
|---|---|---|
| Z | Forward slash + electricity | Very low cooldown, great for spam |
| X | AoE slasher | Low cooldown, combo follow-up |
| C | Wide purple AoE radius | Clips to player, multi-target potential |
| F | Dragon summon cutscene | Highest damage; unlocked via Mastery |
Yes. True Aizen (B10) is currently the top sword in the Huge Update meta, outperforming Yamato and Blessed Maiden in raw damage output.
No. The base Aizen Sword is a requirement but is not consumed when you purchase True Aizen.
Plan for at least 120–135 Chrysalis Sigils total — 75 for the sword purchase and 45–60 more for the F-Move Mastery boss fights.
You must be Level 8,500 or higher to begin the Hogyoku Quest that unlocks Soul Society Island.
The True Aizen NPC is located on Soul Society Island, directly behind the boss spawn point. The F-Master NPC is on the roof of the tallest building at the back of the island.
