Kitsune permanent fruit

Kitsune combines blue-flame attacks with a fox transformation. Its Tail Meter must reach three tails before transformation is available. Transformed Kitsune can run on water and can carry an allied player, giving the full fox form movement features beyond its attacks.

This is Permanent Kitsune, not a consumable physical fruit. Once redeemed, you can re-equip it through the in-game Shop or Blox Fruit Dealer after switching to another fruit.
