When a giant squid-like alien monster attacks Earth, four female soldiers are tasked with defeating it with the help of giant robots which they pilot.
- Anguished Declaration of Love: Rin declares that she's in love with Commander Otsuya while the girls are fighting the squid.
- Conspicuous CG: The squid and the robots are very obvious CG.
- Limited Animation: Much like in Mars of Destruction, but the squid takes the cake; it rarely ever moves, and even when it does, it mostly just slides awkwardly.
- Shower Scene: A flashback shows Rin taking a shower, but with no explicit nudity.
