The Raven Secret Technique: First Symphony of Pain: Blood Song is a technique that is useable only by ravens, and is derived from the unique pitch of their screeches, which greatly affect humans. After being summoned in a large flock, the ravens will begin to fly in circular patterns around their target, then will begin to release a series of high-pitched cries from their mouths. The sound of the cries causes damage to the auditory nerve, temporary loss of hearing, intense pain, and hallucinations. The user controls the flight paths of the ravens by emitting chakra from their fingertips and turning it into high-frequency sound waves, making avoiding the ravens very difficult. Additionally, the ears of the target will bleed after exposure to the screeches, hence the name of the technique.
