Aooni the Movie

The cultural anthropology club at a school in the remote Japanese countryside is doing a report on the AoOni, a mythical creature that inspired a hit video game. They find that the AoOni was based on a creature who may live in their own area. But things take a horrible turn when they learn that the creature might still be real, and that the creator of the AoOni game has just committed suicide before they were to meet with him...
