防波堤を守れ、巨大メカが盾で迎撃

Original retro 2D mecha anime action, chunky industrial robot design, traditional cel shading, painted blue-gray storm clouds, burnt-orange armor against a cold ocean. A single heavy bipedal rescue mecha with a large rectangular left-arm shield stands on a concrete breakwater. An unmanned black armored torpedo drone skims just above the seawall toward it. Ten seconds, fast real-time action with massive physical weight, three continuous cuts. 0-3s: low lateral wide shot, the drone accelerates toward the mecha; the mecha takes two heavy steps, braces its rear foot and angles the shield across the drone's path. 3-6s: cut closer at impact, the drone strikes the shield, the mecha slides backward two meters with its feet scraping concrete and knees flexing, shield metal buckles slightly, spray explodes against the seawall behind it. 6-10s: cut wide as the mecha uses a short burst from its back thrusters to drive forward and rotate the shield, redirecting the drone sideways off the breakwater into the ocean; a huge plume of water rises, the mecha skids to a controlled stop with shield still raised. Clear readable momentum, mechanical joints move consistently, impacts cause displacement before recovery. No weightless hovering, no slow motion, no frozen poster poses, no human injuries, no text or logos. Thruster burst, metal strain, heavy foot impacts and crashing waves, no dialogue or music.
