(Ryou is an advanced usage of Armament Haki which is commonly used by the people of Wano. Although Ryou emission simply means Haki to them, its usage is very different. It allows the user to let Haki flow through their body calmly and emit it from one point, allowing them to break through even the toughest of defenses.)

(Internal Destruction is a very advanced form of Armament Haki that is available to only a handful of people in the One Piece world. This form of Haki works the same as Ryou. The only difference is that it destroys the target from within, dealing internal damage without having to pierce the exterior.)
