Koutetsu Tenshi Kurumi

Japan, during the Taisho Era (1912-1926) – A young priest-in-training named Nakahito Kagura accidentally discovers a hidden laboratory belonging to a scientist named Ayanokouji. Inside, he finds Kurumi—a Steel Angel originally engineered for advanced military combat. When an attack by the imperial army causes chaos in the facility, their lips accidentally meet. This kiss awakens Kurumi, who recognizes Nakahito as her sole master. With the army pursuing them and Kurumi's "sisters" Saki and Karinka also awakened, Nakahito, Kurumi, and Professor Ayanokouji must flee while uncovering the truth about the Angel Heart—the source of the Steel Angels' power. The manga "Koutetsu Tenshi Kurumi" began its serialization in Ace Dash but was discontinued after only 7 issues. It then moved to the newly created Ace Next and later featured in Shounen Ace for its final nineteen chapters. The series had nine volumes published in English as "Steel Angel Kurumi" by ADV Manga from December 29, 2003, to December 7, 2004. However, the license was dropped, and the publisher eventually went defunct.
