After losing her elderly grandfather Wasuke to lung cancer in the hospital she was visiting, fifteen year old civilian girl Yasmin Itadori is approached in the hospital lobby by young male sorcerer Megumi Fushiguro, who asks her to hand over a unholy and dangerous object she and her two friends Setsuko Sasaki and Takeshi Iguchi had found outside their high school earlier in the day. However, Yasmin then tells Megumi the object had already been removed and tosses him the box, also letting him know her two friends had suggested they unravel the wrapping around the object to see what it is. After this, he asks her to go with him to the high school she and her two friends attend. Once at the high school's entrance, they go in at the same time and manage to save Setsuko and Takeshi. The ensuing battle leads to Yasmin becoming a vessel for the ancient evil inhuman being whose soul the unholy object is a part of in addition to the appearance of diligent minded sorcerer Gojo Satoru and his sweet natured wife Rina, both of whom are twenty eight.
