How to Get Sailor Piece Crystal Key
Crystal Key is required to play the Crystal Defense mode at Punch Island. Without Crystal Key, you cannot play this mode and earn crystal coins, which are required for Anti-Magic Sword purchase. Crystal Key can be obtained by eliminating SEA 2 NPCs (very low drop rate). You can read my SEA 2 guide here. Go to any SEA 2 island (Starter, Bizarre, Punch) and eliminate the NPCs (e.g. Fast Ninjas at Punch Island). Keep grinding until you get the crystal key.

How to Get Crystal Coins in Sailor Piece?
You can obtain crystal coins by playing the crystal defense game mode. Head to Punch Island and go to the back side (get past the fast ninja enemies) and you will find three NPCs in the last. One of the NPCs there is the Crystal Defense NPC. Interact with him to get started.
