Ittoryu, or 1 Sword Style is a Fighting Style that consists of powerful, versatile techniques unleashed by a single blade. This style is based on combos and can be used for grinding and PVP. It takes a heavy toll on stamina but can dish out a lot of damage if your sword is great.

This style is generally used without a devil fruit, most people abandon it if they get one.

  • This fighting style is good for grinding and pvp. Keep an eye on your stamina though. The rapid slashes is extremely useful in farming, and the 1SS is a great replacement if you don't have a good fruit.
  • One-Sword Style can not be used alongside a fighting style as it counts as one itself.
  • Your first Katana can be bought for  999 on the same island One-Sword Style can be found, which is required to unlock the 1ss (Roca Island).
