Water Breathing

Water Breathing is one of the main Breathing Styles directly derived from Sun Breathing. Water Breathing has approximately 10 known forms in addition to one made by the Current Water Hashira: Giyu Tomioka.

The Water Breathing combat and breathing style mimics water, specifically the flow, flexibility, and adaptability of the liquid, and replicates it with the user's movements, techniques, and abilities. Most, if not all, known techniques involve the user bending their body, arm, and weapon in a flowing motion. When utilized properly, the user visualizes water in varying shades of blue with white wavy patterns akin to waves resembling water found in classical Japanese paintings, to seemingly emanate from their weapon, surroundings, or themselves.

It is said to be the most common Breathing Style among Demon Slayers due to being the easiest to learn for beginners. A known Cultivator of Water Breathing in the Demon Slayer Corps is Sakonji Urokodaki, though there are other Cultivators as well. The Eleventh Form is an original technique created by the current Water Hashira Giyu Tomioka.

The swordsman increases the number of consecutive strikes and slashes along with improving its accuracy to contact a specific target during a chaotic situation.""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 efficiency are enhanced underwater, where the user can draw water around their weapon to enhance their slashes.""Whirlpool: Flow - A combination of Third Form: Flowing Dance and Sixth Form: Whirlpool.

Ideal when fighting in a place with no solid foothold.""Ninth Form: Splashing Water Flow - Turbulent - An improved version of Ninth Form: Splashing Water Flow.""Tenth Form: Constant Flux - The most powerful Water Breathing technique. The user performs a continuous flowing attack which takes a form of a water dragon that increases in strength and power with each rotation.""Eleventh Form: Dead Calm - A powerful technique with phenomenal defensive capabilities and the personal creation of the current Water Hashira, Giyu Tomioka. Giyu ceases all body movements and enters a state of complete tranquility, deflecting, blocking, and cutting any incoming attacks with the imperceptible speed with his blade. However, its effectiveness is limited as fast and numerous attacks can breakthrough."
