Зэт-Майнд

Old school is back! And girl power reigns supreme! Ayame, Sumire, Renge, and Satsuki are charged with the protection of the Earth from a powerful new enemy. But these girls may be in for more than they`ve bargained for! They`ll have to not only master the experimental mobile armor: Z-Mind, hold down their part time jobs, all this while keeping their lives... normal! But will this be enough to stop the forces of evil from conquering the Earth? (Source: AniDB)
