In canon, what Gojo tells Geto before he dies is never shown explicitly, so there are only strong hints and popular interpretations rather than a fully confirmed answer.

Quick Scoop

  • The manga and the Jujutsu Kaisen 0 movie deliberately censor Gojo’s lips during that scene, so his exact line is hidden.
  • Official materials and staff have only suggested the tone (something embarrassing, emotional, and never said between them before), not the precise words.
  • Two big fan-favorite answers dominate discussions:
    • “You are my best friend, my one and only.”
* “I love you.” (linked to the repeated “I love you” lines from Yuta and Rika right before).

Why many fans think it’s “You are my best friend”

A commonly cited clue is a later scene where Gojo gives Yuta his ID and says it was picked up by “my best friend, my one and only.”

Many readers take this as a parallel: the idea is that Gojo told Geto the same thing in his final moments, affirming that he still sees him as his one friend despite everything.

This reading fits Geto’s soft, almost peaceful reaction as he dies, as if he heard something warm and comforting rather than a cold goodbye.

Why others think it’s “I love you”

Another widely discussed theory points to the build‑up with Yuta and Rika repeatedly saying “I love you” just before Geto is gravely injured.

Because the anime and movie then mute Gojo’s line, some analyses argue this sequence is intentional foreshadowing that Gojo’s final words are also “I love you,” echoing what Geto just heard from Yuta and Rika.

This interpretation leans into the emotional and possibly romantic subtext that many fans see in their relationship and matches comments that the words are “embarrassing” and unlike anything they’ve said to each other before.

What’s actually confirmed vs. fan theory

  • Confirmed by the series:
    • The line is hidden; we can’t read his lips.
* It deeply moves Geto, who smiles just before dying.

* Side/voice‑actor comments describe the words as short and embarrassing, something they hadn’t said to each other before.
  • Not officially confirmed:
    • “You are my best friend, my one and only.”
    • “I love you.”

Both are inferred from visual and narrative clues plus later dialogue, not directly stated in the manga or film.

So, what did Gojo tell Geto before he died?

Putting it all together:

  • The series never prints the exact line.
  • The two most supported readings are:
    1. “You are my best friend, my one and only.”
2. “I love you.”, tied to the “I love you” motif around that scene.

Most discussions accept that whatever the exact wording, it was a brief, deeply affectionate confession that reassured Geto he was still Gojo’s one and only friend at the very end.
