Yuji's Sister.

In a bustling metropolis, Mirai wakes up to a life she doesn't remember. As she begins to piece together her past, haunting visions of monstrous figures and cryptic symbols plague her thoughts. Guided by her steadfast brother, Yuji, she uncovers glimpses of her former life - a world where the realms of the every day and the occult intermingle.

As the layers unfold, the unbreakable bond between the siblings lights their path. They find themselves confronting the enigmatic world of Jujutsu and its Curses. Amidst this chaos, an unsettling truth dawns on Mirai: she recalls her name as Y/N and slowly grapples with the shocking realization that she now inhabits the body of Mirai Itadori.
