The jealousy spiral between Nako and Uruka is the actual plot, not the mecha. Two girls tearing each other apart over someone they both want, dressed up as a cute comedy that never lets you forget how messy and real that kind of love actually is. The show knows exactly what it is: a romance between two girls where the Steel Angels are just an excuse for them to keep colliding, keeps apologizing, keeps reaching for each other anyway.
Nako Kagura's ordinary high school life explodes the moment she accidentally activates Kurumi, a militarized android built seventy-five years in the past. One kiss cements their bond, and suddenly Nako's home becomes ground zero for mechanical chaos. Her best friend Uruka isn't thrilled about the sudden competition for Nako's attention, so she escalates things by commandeering her father's secret weapons arsenal to destroy the steel angel once and for all. But Uruka's sabotage backfires spectacularly. More androids wake up, each convinced they deserve to be Nako's primary companion. What starts as a personal love triangle spirals into an all-out mecha free-for-all, with rival Steel Angels battling across the city while Nako watches her peaceful existence crumble. Nako must navigate jealous androids, military conspiracy, and her own growing feelings while preventing total destruction. This is comedy that swings between heartfelt romantic moments and absurdist mechanical warfare. Perfect for anyone who enjoys romantic entanglements complicated by giant robots and android romance that takes itself just seriously enough to land the jokes.
