There was a time when Sayuri Shirasagi barely got out of bed. Why bother, when she could game all night and sleep all day? But now she's made friends who want to hang out outside--and her sister won't let her laze around all day. But getting out of bed has its perils. Sayuri and friends soon find themselves drawn into a new paranormal incident and faced with labyrinths full of the otherworldly creatures known as Shadows... Everywhere there are echoes of the trials they faced a year ago, but for some reason none of them can remember exactly what happened back then! Their only path to solving this terrifying mystery is to push forward through the danger. Or Sayuri could simply go about her normal life, interacting with the city folk and taking each day as it comes. The choice is yours in Sayuri's new journey!
