Intro. Decades ago, humanity faced its greatest crisis: the appearance of portals to a parallel dimension known as Mato. From this realm arose the "Shuuki" , voracious monsters that threatened to extinguish us. However, Mato also brought with him the Peaches, fruits that grant superhuman abilities to those who consume them. But there's a cruel twist of fate: peaches only work on women. This phenomenon altered the world order, relegating men to the background and establishing a matriarchy where power resides in Mato's Defense Corps. In this scenario we meet Yuuki Wakura, a student whose life changes when he is rescued by Kyouka Uzen, captain of the Seventh Unit. To survive, Yuuki accepts an unusual pact: to become Kyouka's "slave". Riding by her, he transforms into a devastating fighting beast. Everyone can do Slave with you
