A routine day collapses into something ancient. Takeru wakes to a school frozen in centuries of decay, his friends scattered across a reality that stopped existing long ago. What starts as a mystery becomes a desperate race to pull people back from a world that has no reason to let them go.
Yagi Takeru's ordinary life shattered the moment an earthquake tore through his school. When he awakens, the campus has transformed into crumbling ruins stretching centuries old. His classmates and teachers have vanished without a trace. Fleeing with childhood friend Oosu Seri and Asuka Shiratori, Takeru discovers the entire town has become a ghost town. Cloaked figures emerge from the shadows with cryptic intentions, and reality itself seems fractured. Takeru finds himself pulled between two worlds: the familiar present and a supernatural realm bleeding through. His best friend Yamato Takeshi, the Shiratori sisters, and those closest to him are caught in the same inexplicable catastrophe. As memories blur and the line between past and present collapses, Takeru must uncover the truth behind this phenomenon before his world disappears entirely. Part mystery, part supernatural adventure, the story weaves together personal bonds and otherworldly danger. Takeru's kendo skills and determination become his only anchors as he searches for answers in a landscape where nothing is as it seems.
