The Seven Mysteries and the Cursed Doll Aya
In order to uncover the truth behind the mysterious death of her close friend, the protagonist ‘Seira’, together with the members of the school newspaper society, ‘Tae’ and ‘Hime’, ventures into ‘U School’ late at night, a place shrouded in silence and darkness.
Set against the backdrop of U School, in addition to the ‘Seven Mysteries’ passed down through the ages, a unique and eerie urban legend is earnestly circulated amongst the students: ‘If you perform a certain ritual, the [Cursed Doll, Aya] will appear and curse the object of your hatred to death’.
To verify this urban legend, Seira and her friends performed the forbidden ritual. However, this was not the gateway to the truth, but merely the beginning of a cycle of inescapable nightmares and despair…
