Hardworking Lilica and the popular top student Rurika are ordinary middle schoolers whose friendship is shaped by a quiet imbalance. Lilica admires Rurika's kindness and dependability but harbors a persistent inferiority complex, feeling she can never measure up academically or socially. One day, a voice from Lilica's smartphone calls out to her, granting her the power to transform into a magical girl. The voice asks her to fight against monsters called Degenerators that appear in the city. As Lilica uses her new abilities, she slowly builds confidence, but the secret of her double life strains her relationship with Rurika. Rurika grows suspicious and begins to question whether Lilica is hiding something, while an obsessive, possessive side of Rurika's feelings for Lilica emerges.

The story unfolds across three volumes. In the first volume, Lilica becomes a magical girl and learns to battle the Degenerators, struggling to balance her ordinary life with her newfound responsibility. The second volume deepens the tension when Rurika directly suspects Lilica of being the magical girl, and a new, orange-clad magical girl appears—someone who is neither friend nor typical enemy, introducing further complications. By the third volume, Lilica discovers that Rurika is also a magical girl, a revelation that shakes her trust. A Degenerator offers Lilica a chance to join their side, but she refuses and fights back. Meanwhile, Rurika's inability to accept Lilica's growth causes her own desires to spiral out of control, leading to a confrontation that forces both girls to question what it means to be "special" and what they truly want from each other. The series weaves together magical-girl action, psychological tension, and the emotional friction of adolescence, exploring themes of self-worth, envy, and the line between affection and obsession.
