Persona 3, first released by Atlus in 2006, follows SEES as they investigate Tartarus and the Dark Hour. Junpei Iori provides comic relief, and Yukari Takeba regularly calls him Stupei when he says something foolish, a nickname that stuck with fans. His attempt to play Ace Detective gave the insult a new form as Stupei, Ace Defective, and the short exchange later circulated online as a reaction clip and meme sound. It remains popular with Persona fans because the joke summarises their dynamic in a few seconds.
