Eriana Foster is a young foreign sorcerer from America, transferring to Jujutsu High to begin her training. She begins as a first year along Geto and Sotoru, but one mission leaves her grievously wounded, her eyes melted by acid spat by a curse. Her cursed technique is that she only has a reverse cursed technique, in that she can heal people by showing them affection. Her blindness remains an issue for the rest of her life, as she cannot heal herself. Satoru and Geto take it upon themselves to help her get through the rest of her training, although she became deathly afraid of going out on missions, so she was allowed to stay behind and be there as pure support in case somebody got hurt. The story follows the three teens as they navigated their new challenges on all sides.
