Ninja Art: Crow Call Jutsu

The user first summons a flock of crows. After having the crows swarm around the opponent, the user has the crows simultaneously start crowing. The sound affects the opponent's mind, causing vertigo, loss of balance and motor control, and hallucination. The opponent can even be affected if their ears are plugged by resonating the sound through the water in their body, possibly causing even greater effects depending on how well hydrated the opponent is.
