Decades ago, gates to an otherworldly and dangerous dimension known as Mato-the âDemon Cityâ-appeared across Japan. Those who partook in the âpeachesâ growing there gained unique abilities-but only if theyâre girls. When down-in-the-dumps high school boy Yuuki Wakura finds himself caught up in a gate, heâs saved by Kyouka Uzen, the beautiful commander of the 7th squad of the Demon Defense Force, who...orders him to become her slave?!
