Phenomeno

The novel is about a young student named Yamada, who recently moved to Tokyo, where he rented a big old house, because of the cheap rent price.

Although, there is definitely something deadly mysterious around that house.

There are scratches at night and someone cuts numbers on the house walls.

Yamada asks his friends from occult web-forum to investigate it.

A visual novel adapting the first case of Phenomeno was released by Nitroplus on June 16, 2012.
