Learn how to get Aizen in Legacy Piece by finding Mr. Plans on Hollow Island, meeting the Rank S requirement, and collecting every material needed for Mind Master.
To get Aizen in Legacy Piece, find Mr. Plans on Hollow Island and unlock Mind Master after collecting 2,000,000 money, Rank S, 3 Hogyoku, 1 Anglerfish, and 1 Soul Right.
Aizen is the Mind Master spec in Legacy Piece, and the unlock runs through one NPC: Mr. Plans on Hollow Island. The grind is mostly boss farming, because you need money, Rank EXP, Hogyoku, and chest drops before Mr. Plans will give you the spec.
Aizen requirements in Legacy Piece
| Requirements | Amount or location | How to get it |
|---|---|---|
| NPC | Mr. Plans on Hollow Island | Find him on top of one of the buildings. |
| Money | 2,000,000 | Earn while playing and farming bosses. |
| Rank | Rank S or higher | Gain Rank EXP by killing bosses. |
| Hogyoku | 3 | Farm the Aizen boss. |
| Anglerfish | 1 | Open chests dropped by bosses and NPCs. |
| Soul Right | 1 | Open chests dropped by bosses and NPCs. |
Before you chase the boss drops, check the full unlock list at Mr. Plans. Aizen and Mind Master are the same spec here, so if the NPC mentions Mind Master, you are in the right place.
Once you have every requirement, go back to Mr. Plans and unlock Aizen. If the NPC still blocks you, the missing piece is usually Rank S or one of the chest items.
Where Mr. Plans is on Hollow Island
Mr. Plans is on Hollow Island, standing on top of one of the buildings. This is the Aizen NPC, and it is also where the game labels the unlock as Mind Master.

How to get Aizen in Legacy Piece
STEP 1/9
Go to Hollow Island
Travel to Hollow Island, where the Aizen unlock NPC is found.
STEP 2/9
Find Mr. Plans
Look on top of one of the buildings for Mr. Plans, the NPC for Aizen or Mind Master.
STEP 3/9
Check the unlock requirements
Confirm that you need 2,000,000 money, Rank S or higher, 3 Hogyoku, 1 Anglerfish, and 1 Soul Right.
STEP 4/9
Use Boss Tickets on the island
Spawn the Aizen boss on Hollow Island with Boss Tickets, which reportedly drop from many activities while playing.
STEP 5/9
Farm the Aizen boss
Keep defeating Aizen because he can drop Hogyoku, and you need 3 Hogyoku for the spec.
STEP 6/9
Open boss and NPC chests
Open chests dropped by bosses and NPCs for Anglerfish and Soul Right, since these chests do not simply spawn around the map.
STEP 7/9
Build Rank EXP from bosses
Kill bosses to gain Rank EXP, and keep farming Aizen if you still need his drops.
STEP 8/9
Reach Rank S
Get 15,000 Rank EXP for Rank S, then check your progress in the stats menu by scrolling to the bottom.
STEP 9/9
Return for Aizen
Once every money, rank, and item requirement is complete, return to Mr. Plans and unlock Aizen.
Farm Aizen for Hogyoku and Rank EXP at the same time so the boss grind also pushes you toward the Rank S requirement.

How each Aizen material works
| Requirements | Source | Notes |
|---|---|---|
| 2,000,000 money | General farming | Save the full amount before returning to Mr. Plans. |
| Rank S | Boss kills | Requires 15,000 Rank EXP; check progress in stats. |
| 3 Hogyoku | Aizen boss | Farm Aizen repeatedly; exact drop odds are not confirmed. |
| 1 Anglerfish | Boss and NPC chests | Open dropped chests while farming; exact odds are not confirmed. |
| 1 Soul Right | Boss and NPC chests | The item is listed as Soul Right; get it from dropped chests. |
| Boss Tickets | General play | Used to spawn Aizen; reported to drop from many activities. |
The cleanest route is to make the Aizen boss your main farm whenever possible. He is tied to Hogyoku, and every boss kill also helps with Rank EXP, so you are not splitting your time across separate grinds unless you need extra chests.
Anglerfish and Soul Right are the parts that can slow the run down because they come from dropped chests, not guaranteed boss rewards. Open every chest you get from bosses and NPCs while you are already farming for Hogyoku and Rank EXP.
Avoid these Aizen farming mistakes
Also, do not ignore Rank EXP. You can have the money and rare items ready, but Mr. Plans still requires Rank S, which means 15,000 Rank EXP. Check the bottom of your stats menu before assuming the unlock is bugged.
Finally, be careful with guides for similarly named Aizen unlocks in other Roblox anime games. Sailor Piece True Aizen instructions, bosses, currencies, and materials are not the Legacy Piece Aizen route, so do not mix those requirements into this grind.
Aizen Mind Master showcase notes
Mind Master looks like a flashy, clean spec once unlocked, and early player impressions describe it as one of the stronger and more sought-after powers in Legacy Piece. Treat that as a community-style read for now, not a settled tier-list verdict.
The important limitation is that exact ability names, damage values, cooldowns, and resource-bar behavior are not consistently documented yet. That means Aizen looks worth grinding if you want a stylish high-end spec, but a full build or combo route should wait for more stable testing.
What to farm after Aizen
After unlocking Aizen, the next useful grind is a proper Mind Master build, especially if you want to tune stats, traits, and playstyle around the spec. Since the unlock already teaches you the core loop, it also makes sense to refine your Hogyoku and chest farming route for future updates.
If you like this spec’s theme, keep an eye on other Bleach-themed Legacy Piece specs too. Aizen is the big target here, but the same boss-focused farming habits should help with later high-end unlocks.
