This thing knows exactly what it's parodying and attacks every anime trope with the precision of a comedy that never wastes a setup. The meta-humor lands because it's not trying to deconstruct anything serious, just riff on the absurdity of mecha shows and incompetent task forces until the joke exhausts itself naturally. In ninety minutes, it does more with genre self-awareness than most full series manage in twelve episodes, and the Demon Seed's charisma makes their crimes funnier than they have any right to be.
A special police unit formed to stop the Demon Seed gang keeps getting outmatched. The gang's mecha body suits let them pull off spectacular crimes that wreck the city and humiliate the cops, and the public is turning against the force. Chief Hattori comes up with a bizarre plan while drunk: find a crime fighter so captivating that nobody will care whether the gang is beaten, namely an idol singer. The recruit is Maron Namikaze, a young teen who can neither sing nor dance but has superhuman strength. Now the unit must train her into a star and turn her into their ultimate weapon against the Demon Seed. A two-episode OVA mixing comedy, mecha, music and sci-fi.
