In Lanxing AD 3068, a bill was passed making the artificial human project legal. More artificial humans began to be manufactured to perform a series of dangerous tasks such as exploration and defense. After the technology for producing artificial humans was fully mature, the Alliance Council proposed the Noah plan to create new humans. This plan is carried out secretly by major laboratories in the alliance. Lucy is one of the products of this plan. According to the original plan, Lucy should have been included in the alliance's property directory by now. However, due to various changes, she left her birthplace, the Addis Abak Laboratory, and began to observe the world as a free person, learn human emotions and understand the reasons for her own existence.
