The manga Jujutsu Kaisen was released in 2018, but it truly captured the attention of audiences after the anime adaptation premiered in 2020. Fans are not only drawn in by the storyline and characters but also by the opening theme song of the series.
In the first episode of the anime Jujutsu Kaisen, titled “Kaikai Kiten,” we see Yuji sitting in a train compartment submerged in water. Initially, he appears to be asleep before awakening and ultimately being possessed by Sukuna.

No one paid much attention to him for a long time, viewing him merely as a plot device. However, when Jujutsu Kaisen reached chapter 264, revealing Yuji’s true potential, we must look back and see if this was cleverly foreshadowed from the beginning.
In chapter 264, the battle between Sukuna and the sorcerers reaches new heights. The heroes have tried everything, yet nothing seems capable of challenging the King of Curses. Just when all hope seems lost, the main character turns out to be the dark horse in this story.
By the end of the chapter, Yuji unleashes and manifests his domain expansion, confronting both Sukuna and his own inner self. His domain resembles a train station (specifically, Shibuya Station) with only two individuals present inside. This chapter concludes with Yuji urging Sukuna to join him, possibly leading to a train journey.

This revelation makes fans excited about Yuji during the initial moments of the anime. It’s possible that Gege Akutami had already envisioned Yuji’s domain expansion long ago. Alternatively, the author might have drawn inspiration from the anime to incorporate this detail into the manga.
According to the details, this marks the first time Yuji has manifested a domain expansion – the most powerful technique in the series, considered the pinnacle of Jujutsu sorcery, and only a select few characters can utilize it. However, this chapter does not reveal any further details about Yuji’s domain expansion, aside from its unique appearance.
One fan commented on Yuji’s domain expansion: “It ends in a place that just started… Gege is a genius.” Another fan added: “Yuji and Sukuna in a train station… it’s right in front of us the whole time.”
We still haven’t seen how Yuji’s domain expansion can truly confront Sukuna. As Jujutsu Kaisen approaches its conclusion, it’s possible that this is the climax of the battle. This implies that Sukuna might meet his end at the train station.
Jujutsu Kaisen chapter 264 is set to be released on July 28, 2024.
