Kuchioshi ~Ensa no Utage~

An evil spirit haunted the old mansion. Many people have died in that house, it was said. Some students decided to test the rumors and sneaked in one night. What awaited was beyond their imagination... A fickle ghost with a desire to kill the mansion's evil spirit possessed Kakoto, a high school girl with supernatural senses, to force her into Kakoto's classmate's dreams and kill the evil spirit. But this is no game. Human life is strangely linked to the body-hopping spirits. Your choices are a matter of literal life and death for the protagonist and other humans. Will Kakoto make it out happy, or even alive?
