Sailor Piece NPC Locations: Quest Givers, Trainers, Sellers & More

NPCs are your lifeline for quests, upgrades, and summons. They handle quests, training, sales, and summons. Most clusters near spawns, landmarks, or key structures.

Endgame Sea 1: Ninja (Strongest Shinobi trainer/seller), Lawless (Power/Atomic masters and summoner), Tower (Infinite Tower portal, shops, merchant).
Special/Sea 2: Sea Traveler (World Island for Sea 2 access), various masters on World Island Sea 2, guild/cosmic NPCs on Punch Island, Valentine Island (Cupid/Madoka if event-active).

Remember, exact spots are usually near portals, cliffs, buildings, or bosses so make sure to explore landmarks for easy finds.
