The Duality of Itadori: The design masterfully illustrates the duality of the protagonist, Yuji Itadori. His earnest, kind-hearted face is shown in the upper half, while his reflection, or darker self, reveals the menacing grin of Sukuna. This split image symbolizes how Sukuna lives within Itadori's body and soul.

The 'King of Curses': Ryomen Sukuna is a terrifyingly powerful ancient curse, known as the "King of Curses." He became a part of Itadori after Yuji swallowed one of his cursed fingers to save his friends. Sukuna's reflection on the shirt showcases the chaotic and malevolent nature that lurks beneath Itadori's cheerful exterior.

Symbolic Kanji: The Japanese kanji characters featured on the shirt add another layer of depth to the design. The characters above Itadori's head read "悠仁" which is Yuji's name. The characters below Sukuna's reflection read "宿儺" which is Sukuna's name. This placement visually reinforces the constant struggle for control between the two beings.

Dynamic Style: The design uses sharp, angular lines and a split-color pattern (red and blue) to emphasize the conflict. The red color is often associated with the chaos and power of Sukuna, while the blue represents the calm and heroic nature of Itadori. The jagged lines cutting through the center of the design highlight the tumultuous and violent nature of their shared existence.

A Core Theme: This visual representation is at the heart of the Jujutsu Kaisen story. The entire series revolves around Itadori's journey as a vessel for Sukuna, his mission to find and consume the rest of Sukuna's fingers, and the constant threat of Sukuna taking over his body. This shirt perfectly encapsulates that central theme.
