Introduction

Episode 12 of Jujutsu Kaisen Season 1, titled “To You, Someday,” is a pivotal point in the anime’s first season. The story blends emotional storytelling with dark, philosophical undertones as Yuji Itadori faces one of his most heartbreaking challenges yet. The episode delves into friendship, morality, and the devastating power of curses, setting the stage for the next phase of Yuji’s journey.

Plot Summary

Rising Conflict

The episode opens with Kento Nanami and Takuma Ino battling hordes of transfigured humans in an underground sewer. Nanami orders Ino to handle containment while he pursues the curse responsible — Mahito. Meanwhile, Yuji Itadori ignores instructions to stay out of the fight and rushes toward Satozakura High School, sensing something terrible has happened.

Yuji Meets Junpei

At the school, Yuji encounters his friend Junpei Yoshino, who is using his newly learned cursed technique — a jellyfish-like shikigami called Moon Dregs — to attack one of his former bullies. Junpei’s rage and despair drive him to lash out, influenced by Mahito’s twisted teachings that humans have no real hearts.

Yuji tries to reason with him, reminding Junpei of his late mother’s kindness and offering him a place at Jujutsu High. For a moment, it seems Yuji’s compassion might save Junpei from his path of vengeance.

Mahito’s Cruel Intervention

Just as Junpei begins to soften, Mahito appears and cruelly manipulates the situation. He uses Idle Transfiguration to distort Junpei’s soul and body, turning him into a grotesque monster before Yuji’s eyes.

Yuji desperately tries to save Junpei, but it’s too late — Junpei dies in agony, symbolizing the shattering of innocence and hope. Overcome by rage, Yuji attacks Mahito with unrelenting fury, landing blows that actually harm the curse — a first for Mahito.

Mahito becomes intrigued, realizing that Yuji can perceive the shape of souls because of Sukuna’s presence within him. He tries to provoke Sukuna into taking over Yuji’s body, but Sukuna refuses, mocking Mahito instead. The episode ends with Nanami arriving to back up Yuji as the two prepare to fight Mahito together.
