YMMV / Dark Cat

• Complete Monster: 1991 OVA: Jukokubo is the former Dark Cat mentor of Hyoi and Ryoi who believes all humans are capable of evil. Causing havoc across Tokyo by allowing humans to be possessed by evil spirits that turn them into monsters, Jukokubo poses as a high school dean to allow several students and teachers to be possessed by his spirits, even devouring some himself to gain energy. Getting his spirits to possess an entire classroom, Jukokubo allows the innocent Aimi to be taken over by the Primordial Evil, indulging in her gradual loss of humanity as she slowly turns into a monster.
• So Bad, It's Good: The OVA itself, but particularly the English dub and its hilariously bad acting.
