Her Frankenstein by Kawashima Norikazu, 1986.
A bullied boy in a Frankenstein mask becomes the pawn of a disabled girl and the pair form a symbiotic relationship that feeds on the terror of their victims in this classic of Japanese psychological horror manga.
The critics: Visually, ‘Her Frankenstein’ is light on gore compared to similar works from the same period, but heavy on dark psychological themes. Abusive and coercive relationships, bullying, revenge, power, and innocence are explored through the childhood relationship of the main characters and the lifelong consequences for the protagonist. -- A.J. Dinsdale, The Aither
