The Girl from the Other Side

The world is split into an inner land and an outer land, and the people of the inner land fear the outer one, where eerie beings carry a curse. On the border, one of those beings finds a girl lying among heaps of abandoned dead bodies. She gives her name as Shiva (Rie Takahashi) and calls him Teacher (Jun Fukuyama), though by every rule of her world, he is the thing she should flee.
