According to the search results, Suguru Geto is a character from the anime and manga series Jujutsu Kaisen. The answer to what happened to him depends on which point in the story you are referring to:

• In Jujutsu Kaisen 0, a prequel movie to the main series, Geto is mortally wounded after losing a fight against Yuta and Rika. Gojo arrives and has a conversation with Geto, intending to kill him. The movie does not show Gojo dealing the final blow to Geto, so fans were led to believe that Gojo spared him. However, it was later confirmed in the manga that Gojo did kill Geto.

• In the main series, Geto is killed by Gojo after attacking the Tokyo Jujutsu Tech school. Gojo chooses not to have Getos body taken in by Jujutsu High, which allows an unknown party to place their brain into Getos body.

Therefore, in both cases, Geto dies. However, in the main series, his body is taken over by a mysterious brain, which allows him to appear in the anime despite being dead.
