“Jujutsu Kaisen 0” leaves viewers with two intriguing mysteries. First, the post-credit scene shows Yuta Okkotsu sharing a meal with the enigmatic foreign sorcerer, Miguel, sparking curiosity about their connection. Second, the enigma of what Satoru Gojo whispered to Suguru Geto before their fateful confrontation remains unsolved, although some individuals hold the answer. Notably, Gege Akutami, the creator, and Yuichi Nakamura, Gojo’s voice actor, are among those privy to this information.
While certainty about Geto’s final words from his dear friend remains elusive, fans have speculated and generated educated guesses. One popular theory suggests that Gojo may have expressed sentiments akin to what he conveyed to Yuta when returning his student ID: “my one and only best friend.” This notion is plausible, given Geto’s disbelief that Gojo could still harbor trust for him after his numerous villainous acts.
The opening theme of the second season, “Ao no Sumika” (“Where our Blue is”) by Tatsuya Kitani, contributes to this theory. The lyrics evoke a sense of nostalgia, mirroring Gojo’s sentiment towards his past at Jujutsu High. Notably, a line in the song reads, “‘We’ll meet again, right?’ in a muted voice,” with emphasis on the voice being “muted” or “unvoiced,” mirroring Gojo’s subdued tone when potentially speaking these last words to Geto.
This theory gains further support from chapter 236 of the manga. The conclusion of Gojo and Geto’s storied journey culminates in a reunion that mirrors their youthful selves, harking back to simpler times. Notably, Gojo’s reaction suggests that he wasn’t aware of this reunion. This aligns with the idea that he expressed a wistful hope for a future meeting, even without empirical evidence of its possibility.
Ultimately, if Gojo did indeed utter these words to his friend at the end of the movie, it may have been because he felt them to be fitting, despite uncertainty about their realization. The bittersweet nature of their final encounter, though not joyous, provides closure for the characters and resonates with fans of the series.
