The action sequences move with a confidence most two-episode OVAs never find, each fight designed to show you what these characters can do rather than waste time explaining it. Character designs hit that specific 90s sweet spot where fanservice and actual personality coexist without apology. It exists entirely in the moment, unconcerned with plot threads or world-building, which means every frame serves the next punch or quip instead of some future payoff that never comes.
Linn escapes her oppressive life in Deep Kyoto seeking her lost brother, only to stumble into Tokyo's dangerous underworld when a chance encounter with the mysterious Miho Kuon saves her from street thugs. Miho, a skilled operative with secrets of her own, takes pity on the runaway and offers shelter, renaming her Kotetsu after the brother Linn desperately searches for. What begins as a simple refuge quickly spirals into something far more complicated when the shadowy Syndicate marks Miho as a target, dragging Linn into a collision course with forces she barely comprehends. Packed with high-octane action sequences and playful humor that undercuts the mounting tension, this OVA balances intimate character moments against explosive set pieces. The chemistry between Linn and Miho carries the story forward, mixing found family warmth with genuine danger. Supernatural elements and sci-fi intrigue lurk at the edges, hinting at deeper conspiracies beneath the surface. This is for viewers who want fast-paced entertainment with heart, where humor and action coexist without apology.
