Kyiosei
The final bell was supposed to signal the end of the school day.
Instead, it marked the end of the world.
At sixteen, Hina Shirayuki was used to the routine of life at Seiryu Academy in Kyoto-early mornings, stubborn teachers, and avoiding the cold gaze of Yuji Ryuzaki, the boy who used to be her everything. Once childhood best friends, their bond shattered three years ago after an argument neither of them ever truly recovered from. Now, Yuji is distant, brilliant, and colder than winter steel-a star baseball player with eyes that no longer look her way.
But when the school bell rang that day, it didn't bring freedom.
It brought screams.
Without warning, the infection spread. Students turned into mindless predators. Classrooms became slaughterhouses. Halls ran red. Trapped inside their school, Hina is thrust into a waking nightmare-one where her only chance at survival lies with the boy who broke her heart and a handful of terrified classmates.
Outside the chaos, her older brother, Haku Shirayuki-a leading doctor and scientist at Kyoto's most prestigious hospital-is racing against time to find a cure. But as Hina and Yuji fight their way through blood-soaked corridors and shattered memories, they begin to uncover a truth far darker than the outbreak itself-one that ties their past to the present, and love to something far more dangerous.
The bell stopped ringing.
Now comes the silence.
And in the silence... only the strong survive.
