Koutetsu Tenshi Kurumi

A dare leads young mystic-in-training Nakahito Kagura into a scientist’s laboratory, where an accidental kiss awakens the mechanical girl Kurumi. She immediately recognizes him as her master, overturning his quiet life with boundless affection and formidable strength.

Kurumi’s creator hopes for more than the military purpose intended for his Steel Angels, but the army will not simply abandon such a powerful weapon. Other artificial girls enter Nakahito’s life as enemies and allies, forcing the gentle boy to confront the forces pursuing his extraordinary companion.
