Fuoto

Fuoto (巫音, "Shamanic Sound") is a type of Fujutsu that infuses Furyoku into sound in order to perceive, generate and manipulate any type of sound waves with varying intensity. Shamans who specialize in Fuoto are known as Ongako (音楽, "Bards").

Capabilities
By using their own body as a sort of an amplifier, the user can intensify the sound of their musical instrument using their Furyoku. Using Fuoto, the user can create, shape, and manipulate sound that radiates outward linearly in the form of a pressure wave. This can be used to attack opponents with sounds of various intensity, to distract and immobilize an enemy, or to take control of them, making it effective for mid-range to long-range combat.

Sound is an invisible, deadly weapon and a versatile tool. At low frequencies, sound can be potentially fatal to living beings by causing internal damage and can easily deafen the caster's opponents. At high frequencies, sound cannot be heard by normal humans, but can be used for sonar-like effects. Since sound vibrations can travel through the air, ground, and water, conventional means of defending against it don't work.
