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...
But he did something terrible 
15 or 16 years ago...
Vor 15 oder 16 Jahren stellte

pero hace unos 15 o 16 años
pero hace unos 15 o 16 años

Ed è stato... mah, quanti anni
saranno passati, 15 o 16?
Mas ele fez algo terrível uns 
quinze ou dezesseis anos atrás...
