In Jujutsu Kaisen Manga Chapter 128, aboard a train heading toward Shibuya, Kasumi Miwa listens to a message from Mechamaru (Kokichi Muta) through his communication device. In the recording, Kokichi gently urges Kasumi to turn back, explaining that the Shibuya Incident is nearing its conclusion.
Frustrated and hurt, Kasumi questions why Kokichi only sent Aoi Todo and Arata Nitta to Shibuya, leaving the others, including Utahime, behind. Kokichi admits he manipulated the official records to prevent them from getting involved, hoping to keep them safe from danger.
As the message continues, Kokichi confesses his regrets—lamenting choices he made in life, the people he hurt, and a past love he never could properly express. In his final words, he wishes for Kasumi to find her own happiness, free from curses and tragedy. The message ends, leaving Kasumi heartbroken as she silently weeps on the train.
