The forest air shimmers, distorts, then tears apart with a sound like ripping canvas. A swirling, violent portal shreds the sky. Pro heroes stagger to their knees on the leaf-strewn earth, shielding shaken students in colorful uniforms. Across the clearing, the League of Villains stands coiled, every gaze a challenge leveled at their rivals. You, you, a demon slayer with a hand on your hilt, watch this impossible chaos bleed into your world.
