House of necromancy by psychic
Though the necromancy that some psychics used to perform long time ago was dangerous as it evoked ghosts and let them haunt people, it was quite popular for its high hitting rate and many people visited there.

One day, the accident happened.
A woman haunted by an evil spirit died all of a sudden during necromancy.
People began criticizing the psychic as a “murder”and believing “she was the reincarnation of Sadako.”
This is how the necromancy got banned and disappeared.

As time has passed, the memory of the necromancy and accident faded away.
A psychic started necromancy again.
Once she gazes into her crystal, the image reflected on her crystal starts getting fuzzy and a skeletonized skull and a woman with long hair appear.

You are hiding inside a coffin said to drive away evil spirits and protect you.
When you take a slow glimpse outside through a gap in the coffin, a woman with long hair is right in front of you!

You will be stricken with the horror of Sadako…
