Unexpected Variable (Jujutsu Kaisen)

Life and death are one in the same. One gives life, while the other retrieves the life after it's death. Some believe that after death that is the end, that they either go to heaven, hell or end up as a wondering soul on earth.

Such as the case of her. Dying at sixteen, she believed that she would move onto the afterlife and stay there until the end of time. But she never would have expected that after dying, she didn't stay dead.

There should have only been one child, a son. Should have. But, in fact there was an unexpected variable, the Itadori family had two children. A son Itadori Yuuji, and the youngest Itadori Shina.

In this life, she will do everything in her power to save and help her older brother Yuuji. No matter what.
