Jujutsu Kaisen 0: How Is [SPOILER] Still Alive In The Anime?

Warning: Contains spoilers for Jujutsu Kaisen 0 and Jujutsu Kaisen volumes 11 and 16-23.The Jujutsu Kaisen 0 movie left one question that wouldn’t be addressed until later: how is Geto still alive in the Jujutsu Kaisen anime? The movie heavily implied that Geto died in the end, yet the anime, which takes place a year after the movie, still has him as an antagonist. There’s an explanation for why that is, although it only recently appeared in the Shibuya Incident arc of the anime.
