Maria, the older twin, endured prolonged bullying by her classmate Ursula and sexual harassment from a counselor named Croft, ultimately meeting a brutal end at the hands of thugs hired by Ursula. After her death, Maria witnessed everything as a disembodied spirit. Her younger twin, Alan—who suffers from antisocial personality disorder—discovered the body and infiltrated the school by assuming Maria’s identity. She investigated the truth and exacted revenge through extreme violence: dismembering Croft, torturing the three bullies to death, sowing discord within Ursula’s family, driving Bram to insanity, and forcing Ursula to dismember her own parents. Amidst the extreme gore, the story explores the paradox of "monsters" and "love": Alan, viewed by everyone as a monster, harbored a profound obsession and tenderness solely for her sister.
