Kira is the secret identity of Light Yagami, the protagonist of Death Note, the manga by Tsugumi Ohba and Takeshi Obata that ran from 2003 to 2006 and was adapted into an anime series in 2006. After finding a notebook that kills anyone whose name is written in it, Light sets out to purge the world of criminals and builds a godlike cult following under the name Kira. Short voice clips of the character circulate widely online, where anime fans and meme editors reuse them in edits, reaction videos and villain compilations, keeping Kira's cold arrogance alive across platforms.
