In this 3D CG-animated movie, Hikiko, a character based on a Japanese urban legend, endures cruel treatment from her parents and classmates, leading to her extreme ugliness from the constant abuse. Seeking revenge, she captures elementary school students, dragging them until they are severely mutilated. A chilling revelation arises when her full name, Mori Hikiko, is reversed to spell 'hikikomori,' symbolizing social withdrawal.
