"Awakening Protocol: Rise of the Slayer" When a deadly infection hits Matsuda High, turning teachers and students into mindless, violent predators, seventeen-year-old Kaito Sakamura finds himself the unlikely key to survival. With each encounter, a mysterious "system" activates within him, granting him new abilities and stats as if he’s in a video game—but this is no game. As his strength and skills grow, Kaito faces an escalating horror that tests his courage, intelligence, and willpower. Now, with his terrified classmate Hana by his side, Kaito must navigate blood-soaked hallways, deadly threats, and the brutal reality that their friends and teachers are no longer human. Survival means mastering the "system" before it’s too late—but as Kaito levels up, he begins to wonder: who or what unleashed this deadly outbreak, and why has he been chosen to survive it?
