Chidori, also called the Thousand Birds technique, comes from Naruto, where Kakashi Hatake created the lightning jutsu and later taught it to Sasuke Uchiha. Its name refers to the sound of a thousand birds chirping, which is why the audio is so high-pitched and frantic. As Naruto clips spread across YouTube, TikTok and soundboard sites, editors began lifting the charge-up sound for their own battles, transitions and power-up moments, and it remains popular because it instantly reads as anime lightning even without any visuals.
