Slayers Crossover

{System Online} {System Activating} {System Activation Complete.} {User Detected: Jake Lucas.} * {Main Quest: Grow strong enough to defeat your foes.} *{Warning: Darkness Approaches. No One Is Safe.}* 200 years ago, humanity almost faced extinction at the hands of the werewolves. The world survived, but the cost was unimaginable. Victory was hard-earned—and the price paid is still unknown. After seeing the war wasn't heading anywhere, the werewolves receded to grow their strength while letting the humans recover. Now, sixteen-year-old Jake Lucas is thrust into a battle he never wanted. Weak, outcast, and haunted by his parents’ brutal deaths, Jake is just trying to survive at Aurora Academy. But when a strange orb activates the Slayer System, everything changes. Quests, skills, and powers that could make him stronger than he ever dreamed. But power comes with a price. With each new level, Jake uncovers dark secrets—about the werewolves, the academy, and the shadows lurking beneath them all. The world is more dangerous than he imagined, and a hidden force is stirring, ready to rise once again. Jake’s only hope lies in mastering the Slayer System—but as the stakes grow higher, he’ll learn the real question isn’t how strong he can become, but *how far he’s willing to go* to stop an ancient evil from being unleashed. **But the system has a final warning: Jake isn’t the only one unlocking power. And the clock is ticking.** ________________ IMPORTANT MESSAGE FOR NEW READERS!!! My first few chapters might come as boring at first or bad that was because I was new to System troupe and I was also new in writing a Webnovel style book. so I will appreciate it if you all can continue reading. Ok so this is for new and probably old readers. Please read the pinned review. I had changed the title from My Werewolf's Slayer System to this just to make it cool and it doesn't affect the main storyline which is about Jake growing strong through the system and getting his revenge on the werewolves. ___________________ 200 power stones= 1 extra chapter. 20 Golden tickets= 2 extra chapters.

"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?

Kaito Sakamura never expected his final year at Matsuda High to turn into a nightmare. What began as an ordinary school day quickly descends into chaos as a mysterious outbreak transforms his classmates and teachers into infected, mindless killers. In the midst of the terror, Kaito suddenly gains access to a strange, game-like survival system that grants him enhanced abilities and displays stats, skills, and even titles. Marked as the “First Slayer” for being the first to kill an infected, Kaito realizes he’s been given a chance to survive—but at a brutal cost. As the infection spreads through Matsuda High, Kaito must fight for his life, leveling up and unlocking new abilities as he battles his way through blood-soaked hallways and barricaded classrooms. But survival is more than just defeating enemies; it means making impossible choices, risking everything for his friends, and finding out the truth behind the outbreak and this strange “protocol” that seems to govern his every move. With each level he gains, Kaito becomes stronger, faster, and more resilient—but he’s not alone. Other students begin to awaken similar powers, and soon Kaito finds himself caught between enemies both living and undead. As he faces off against monsters both human and infected, he begins to uncover a horrifying secret that goes far beyond his school—a secret that could change the fate of humanity itself.
