Eri Harada is finally going to enroll at Mamori High, where her mother decided to send her for some dark reasons. She wouldn't have thought that her high school life was going to make her discover obscure truths and that the rumor would come true.

While she learns more things about her past and about the true motivations of her mother, she soon enough realized that two of her classmates are one way or another linked to it. Kojiro Kimisaki and Ryou Aoi both seem to be the bearer of painful past that they hide differently and with talent.

Mamori High already counts three victims…
Deaths that occurred in strange circumstances.

During her adventure, her steps always take her back to the same question : Is a leprechaun really hiding within the high school?

So… Be careful on the choices you make…
Or it could soon be the end.
