Name: Natsuo Shizui
Age: 11
Likes: sweets, hanging out with Giyu and the others, reading.
Dislikes: Demons, bitter foods.
Personality: quiet, kind, caring, brave.
Breathing style: Water
First Form: Water Surface Slash
The user generates enough momentum to create a powerful single concentrated slash.
Second Form: Water Wheel
The user leaps and vertically spins forward in the air while releasing a flowing attack in a circular motion.
Third Form: Flowing Dance
The user swings and bends their blade in a winding motion along with their body and dances in a flowing pattern, slicing everything in its path.
Fourth Form: Striking Tide
The user makes multiple consecutive slashes while twisting their body and sword in a flowing fashion to deliver multiple blows simultaneously.
Fifth Form: Blessed Rain After the Drought
The user changes the grip on their sword and decapitates the opponent in a single flowing strike that causes little to no pain. It is a “sword strike of kindness” used when the enemy willingly surrenders.
Sixth Form: Whirlpool
The user fiercely twists their upper and lower body, creating a whirlpool of air that cuts anything caught in it. Its effect and efficiently is enhanced underwater, where the user can draw water around their weapon to enhance their slashes.
Seventh Form: Drop Ripple Thrust
The user performs a fast and accurate stab, capable of reducing the impact of a moving target.
Eighth Form: Waterfall Basin
The user cuts the target vertically in a flowing motion which is most effective when they are falling downward.
Ninth Form: Splashing Water Flow, Turbulent
The user changes their footwork in a way that minimizes the landing time and surface needed when landing, allowing the user to move without limits. Ideal when fighting in a place with no solid foothold.
Tenth Form: Constant Flux
The user performs a continuous flowing attack which seemingly takes the form of a water dragon that increases in strength and power with each rotation due to momentum.
Eleventh Form: Dead Calm
The user ceases all body movements and enters a state of complete tranquility, deflecting, blocking and cutting any incoming attacks with imperceptible speed with his blade. However, its effectiveness is limited as fast and numerous attacks can break though. Both Takemaru and Taiko has adapted this technique in order to utilize this state of mind while in constant motion.
Twelth Form: Water Drag, Drizzle Blitz
The user throws out a high-powered slash by inhaling huge amounts of oxygen, increasing the pumping of blood through the entire body, focusing it on the legs, and releasing it all to assault the target. This move was inspired by a user of the Thunder Breathing, though it is weaker in cutting power.
Thirteenth Form: Hydro-sphere
The user continuously spins themselves around while suspended into the air, causing the air to begin to circulate before they then send it outwards, the wind going through a pressurization phase as it then springs towards the intended target in a ball of compressed air.
Fourteenth Form: Cerulean Blue
The user takes in a large amount of oxygen in order to enhance their bloodflow, strengthening their muscular output before now taking a single step forwards. With this single step, the user then releases their body downward for better lowering strength before using the gravity gained from the sudden drop, along with a push from the ground, to rush towards their target and dragging along with them a large wave of water that completely demolishes them with a single strike through the neck area.
