The 'My Name Is Yoshikage Kira' meme stems from a monologue delivered by the main antagonist of JoJo's Bizarre Adventure: Diamond Is Unbreakable. In the scene, Kira introduces himself to a victim with a bizarrely detailed description of his daily routine, including his age, where he lives, his work hours, and his pre-sleep rituals like drinking warm milk. Despite being a serial killer, he insists that his only goal is to live a 'very quiet life.' The speech became a legendary copypasta within the anime community, often used to mock overly specific character introductions or to parody people who value their routine above all else. Its mixture of mundane details and hidden menace makes it a versatile template for shitposting and irony.
