Hilde Schweiker

An OZ volunteer soldier that reports to the Lunar Base that befriends Duo, tries to recruit him, and eventually turns against OZ to works with him and provide him with a cover, working in her salvage yard.. She is injured at the end of the series when fighting against mobile dolls, but appears alive and well again at the end of Endless Waltz. In Frozen Teardrop In MC0012, Hilde leaves Duo, and he travels to Mars. Some time after that, Hilde follows, becoming a librarian in the Lanigreen Republic. Here, she reunites with Duo, and he moves in with her. After he proposes to her, the two marry in MC0015.

However, Duo soon leaves again, and when he returns in MC0016, Hilde has begun to care for the children of a local church orphanage. When the priest of the church leaves it to Hilde and Duo, his debt is also passed to them, with Hilde bearing the load of the debt, and Hilde demands a divorce from Duo. He signs the divorce papers and once again vanishes, but not before promising to help Hilde recover from her debts.

Sometime before Duo returns in MC0017, Duo Maxwell comes into her care, however it is not clear if he was born to her while Father Maxwell was traveling the planet or if he was adopted by the orphanage- Hilde claims she thinks him to be a lovechild of one of Father's women, however Duo muses that the child would have been born while he and Hilde were still together. In MC0017, Father Maxwell brings Naina Peacecraft to the orphanage, placing her in Hilde's care at the request of Zechs Merquise.
