In BOOBIES, you take on the role of a man with the unique ability to rescue heroines from across the multiverse after their home worlds are destroyed. Each girl you save is brought to your headquarters, Zone Zero, where you offer them shelter and a new life. These survivors are classified as Biological Otherworld Organism Beings in Exile, or B.O.O.B.I.E.S for short. As you care for them and strengthen your bonds, they gradually become devoted allies and eventually part of your loyal harem.
