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...
and a male acquaintance said he had 
no idea why his friend committed suicide.
und ein Bekannter sagte aus, dass er einen
Selbstmord nicht für möglich gehalten hätte.
Como su amigo no recuerda
ningún motivo para que se suicidara,
Ya que su entorno no piensa que haya
algún motivo por el que se suicidara,
Un suo conoscente
e um amigo disse que não faz 
ideia de por que ele se mataria.
