Summary
Kurogane Rikuto, a lonely high school student, suffered constant bullying and rejection from his adoptive family and teachers, leaving him with nowhere to belong. On the verge of giving up, he stood on the school rooftop—until monsters erupted from students’ phones, transforming the campus into a blood-soaked nightmare. Creatures once dismissed as weak in games now slaughtered helpless humans. Without a phone, Rikuto watched his tormentors die, and a fierce will to survive awoke in him. As a goblin lunged from behind, his brutal fight for life began.
