The protagonist drives down through a forest road with his girlfriend Nami. She asks about the flowers growing down the road, which the protagonist explains are hypericum, or the "otogirisou". Suddenly the brakes of the car stop working and after an oncoming car rushes by, the protagonist gets the car to come to an emergency stop. Neither Nami or the protagonist are hurt as they leave the car. They see a flickering light in the distance when a strike of lighting hits a tree crushing their car. As rain falls, Nami and the protagonist follow a trail of flowers following the light they saw earlier and stumble upon a Western-style country mansion.

The two enter the house in various ways, such as ramming into the door or breaking a window, and find themselves in a room that is completely silent with only a murky aquarium and suit of armor worth investigating. They call out to see if anyone was there, but there was no response. After hearing noises upstairs, they discover a room which is dimly lit. The door closes behind them and they suddenly see an old mummified woman in a wheelchair. The power goes out and after hearing the sound of creaking wheelchair, the power returns and the room is revealed to be empty. They exit to investigate, finding the suit of armor downstairs is missing.
