I Quit Guarding Demon-Sealing Tower

Charlie has guarded the Demon-Sealing Tower for a millennium, single-handedly holding back three supreme Beast Kings and countless Soul Beasts who fear his blade. Yet, the Sky Kingdom’s royal court casts him aside, branding him unfit and forcing him to abandon his post. Barely half a day after his departure, the tower collapses, unleashing an unstoppable tide of billions of Soul Beasts into the Human World. The fragile balance shatters, plunging humanity into chaos as the consequences of betrayal surface in a desperate fight for survival.
