Fighting styles in Sailor Piece are melee specs tied to trainers, bosses, titles, clans, and item drops. You start with Combat, and every other style unlocks by meeting a specific set of requirements and trading them to the right NPC.
Quick answer: There are 12 fighting styles in Sailor Piece; Combat is free at the start, while the others require boss drops, titles, currency, or clan requirements before a trainer will unlock them.

How fighting style unlocks work in Sailor Piece
The system is simple. A fighting style unlocks when you reach the correct trainer or NPC with every required item, title, and currency amount already in your inventory or on your character. If one piece is missing, the trade does not complete.
Most styles follow the same pattern. First, you farm the related boss for drops, then you collect any money or gem cost, then you make sure title and clan conditions are met, and finally, you speak to the trainer.
That means the real gate is usually the rarest boss drop, not the trip to the trainer.

Anos fighting style requirements
Anos is one of the clearest examples of the full unlock structure because it uses nearly every gate the game has: location, boss farming, title, and clan requirement.
| Requirement | Needed for Anos |
|---|---|
| Trainer location | Academy Island |
| Title | Demon King |
| Clan | Voldigoat |
| Calamity Seals | 65 |
| Demonic Fragments | 12 |
| Demonic Shards | 6 |
| Destruction Eyes | 2 |
| Imperial Mark | 1 |
The boss summoner on Academy Island is the key part of this unlock. The Anos boss drops the required materials, while the clan condition must already be satisfied before the trainer will accept the hand-in.
If you are trying to verify whether the unlock is ready, check the two non-drop requirements first: Demon King title and Voldigoat clan. Those are the easiest conditions to overlook when your inventory already has the boss items.

Trainer and island locations for fighting styles
| Style | Trainer or NPC location |
|---|---|
| Combat | No trainer needed |
| Yuji | Shibuya Station |
| Observation Haki | Desert Island |
| Qin Shi | Boss Island |
| Alucard | Back of Sailor Island |
| Sukuna | Shibuya Station |
| Gojo | Gojo Trainer |
| Madoka | Valentine Island |
| Gilgamesh | Boss Island |
| Anos | Academy Island |
| Strongest in History | Shinjuku Island |
| Strongest of Today | Shinjuku Island |
What counts as a completed unlock
A fighting style is unlocked once the trainer accepts the full requirement set, and the style becomes available on your character in place of basic Combat or alongside your existing specs, depending on how the game presents the swap. The practical confirmation is straightforward: the trainer interaction succeeds, and the style is usable.
If the interaction does not complete, one of three things is usually wrong. You are missing a required drop, you do not have the title or clan requirement, or you do not have enough money or gems.
Titles and clan requirements matter just as much as boss drops. If a trainer refuses the trade, check those first.

Best fighting styles in Sailor Piece
Anos, Gilgamesh, and Strongest in History are widely treated as the top end of the current fighting style lineup. Strongest in History stands out for large area damage, while Anos and Gilgamesh sit in the same top tier because of their raw power and endgame requirement level.
That ranking matters mainly if you are deciding what to farm first. It does not change the unlock process. Every style still depends on its exact trainer, item set, title, and currency cost.
If your goal is to unlock every fighting style, the cleanest way to track progress is by treating each one as a checklist: trainer location, title, clan if needed, currency cost, then boss materials. For Anos in particular, Academy Island, Demon King, Voldigoat, and the full drop set are the complete trigger.
