The Mecha Beneath the School

Create an anime mystery opening at an ordinary school during a violent thunderstorm, where a student hears a heartbeat beneath the gym floor. Start with a handheld hallway shot following muddy footprints, then drop through the floor in a dramatic vertical camera move into a massive hidden hangar. Use a wide lens, rain-streaked windows, pulsing red emergency lights, electric blue lightning, and detailed mechanical cel shading. The student approaches a sleeping mecha covered in vines and faded school emblems. Its eye opens with a soft glow, shaking dust from the rafters, while the camera rushes toward the cockpit and cuts on a thunderous launch signal.
