This two-part story takes place in an alternate universe, where counterparts of our heroines find themselves in the middle of a space opera. In this world, A-ko and B-ko are bounty-hunter partners who hunt giant tortoises on a sand planet. When C-ko is kidnapped by a gang of space pirates, A-ko and B-ko set off to rescue her — thinking only of the reward money offered by her wealthy father. Aided by a pint-sized Galactic Police Officer named Maruten, the girls discover that C-ko's abduction is part of a much larger scheme.
