Intitial premise look like Youkai Shoujo - Monsuga without fighting action, the slice of life story leaning towards Oni ga Deru ka Ja ga Deru ka, The ecchi scene leaning towards Ane naru Mono, The plot leaning towards Mother goddess dormitory
Eyeballs aside (they could affect subconscious fears), who in the world would be afraid of rokurokubi? I mean, maybe if tales of yokai atroucities were fresh in minds of people, but modern person oblivious to most myths?
