This is a curiosity that broke its own mecha. The animation collapses in real-time, the voice acting sounds like it was recorded in a parking garage, and the plot vanishes halfway through an 18-minute runtime. Watch it anyway, because there's something oddly meditative about seeing a show fail this completely and still commit to its own existence.
When an unidentified object materializes above the city without warning, the government's covert response team springs into action. The Alta Mira Agency recruits young women to pilot experimental combat units called Battle Soles, weapons designed to confront the mysterious threat before it destroys everything. Commander Hunagai Otsuya oversees the brutal training program, pushing candidates to their absolute limits. These soldiers know they're expendable, drafted into a conflict they never asked for, armed with technology that demands a terrible price. The city holds its breath as the invader looms overhead, and the only defense lies with those willing to sacrifice everything. Tension mounts between duty and survival as the Battle Soles pilots prepare for a confrontation that may cost them their lives. This one-episode OVA delivers concentrated action and sci-fi military urgency, following desperate soldiers racing against time in humanity's darkest hour.
