Inakami

A man named Okishiro Nagi travels from Tokyo in search of his long-lost sister, who has lived in a remote mountainous area for twelve years. Along the way, he encounters a creature that says "eye to eye" and pursues him. Nagi falls into a pond and struggles to swim. He is rescued by a woman with cat ears, who also repeats the phrase "eye to eye." His journey takes an unexpected and strange turn from there.
