Sound Novel Evolution 1: Otogirisou Sosei-Hen

The car's brakes fail on a forest road. An oncoming car forces an emergency stop. A lightning bolt drops a tree on the vehicle. Rain falls. Following a trail of hypericum flowers through the dark leads to a Western-style country mansion. Inside: silence, a murky aquarium, a suit of armor. No response when they call out. Noises upstairs. A dimly lit room, a door that closes behind them, a mummified woman in a wheelchair. The power goes out. When it returns, the wheelchair is empty. The suit of armor downstairs is gone. The story has started, and there are multiple ways it will end.
