ReLIFE: Final Arc

When the clock runs out, will their borrowed youth become a lasting legacy?

Arata Kaizaki, a disillusioned 27‑year‑old, is thrust back into the chaotic world of high school thanks to the ReLIFE serum. The four‑episode finale follows his last weeks of the experiment, as he wrestles with the bittersweet realization that the friendships he's forged—especially the tentative romance with classmate Chizuru Hishiro—are built on a temporary illusion. Ryou Yoake, the enigmatic mentor who warned him from the start, reminds Arata that once the serum wears off, his classmates will forget him entirely, forcing him to confront what truly matters: the growth he’s achieved and the courage to carry it forward into his real life. Meanwhile, Chizuru, who entered the program as a socially awkward loner, blossoms into a confident, introspective young woman. As her own ReLIFE timer ticks down, she must decide whether to cling to the safety of her newfound circle or step into the uncertain future with the lessons she’s learned. The final arc interweaves their parallel journeys, delivering heartfelt goodbyes, lingering doubts, and a hopeful promise that the impact of a fleeting second chance can echo far beyond its expiration.

This four-episode finale wraps up a sci-fi premise where adults relive high school, focusing on the painful goodbye as memories are erased. Expect heavy emotional beats around regret, friendship, and loss rather than graphic content.
