Professor Kimishiro is loved and respected by his students, but disliked by faculty and administration. He's pushed from his classroom by university politics and takes a team to the jungles of the Amazon in search of new medicines and perhaps a chance to gain back his reputation amongst those with influence back home. Instead of cures, his team stumbles upon a lost temple in the jungle, a place the village guides claim to be 'The House of the God of the Black Death'. What are the temple's secrets, and can any man, let alone a mere boy, survive the plague of an angry God?
Surprisingly, Yotsuya-sempai appears to be an actual person. He's obsessed with creating the scariest stories ever, using the people and situations in Makoto's middle school to stage them. Though Yotsuya is mostly just interested making scary stories, Makoto finds that his stories tend to contain a kernel of truth and that they can reveal their terrible truth in the telling. But as Makoto helps Yotsuya stage his tales, can she convince him to tell the story of the whereabouts of her best friend?
