Chained Soldier

Decades have passed since the sudden emergence of the "Demon City"—a terrifying otherworldly dimension known as Mato—across the landscapes of Japan. Within this perilous realm grow mysterious peaches, fruits that bestow extraordinary supernatural abilities upon those who consume them. Yet these powers come with a single, immutable caveat: they manifest exclusively in women. In response to this ever-present threat, the all-female Demon Defense Force was established to protect humanity from the nightmares that spill through the gates. Caught in the chaos of an ordinary day, high school student Yuuki Wakura finds his mundane life shattered when he is unexpectedly dragged into a Mato gate. On the brink of annihilation, he is rescued by Kyouka Uzen, the formidable and beautiful commander of the 7th squad. But Yuuki's salvation comes with an unexpected and humiliating price—Kyouka immediately declares that his survival hinges on becoming her personal slave. Bound by an unorthodox pact that defies the rules of Mato, Yuuki is thrust into a world of fierce combat and powerful women, forced to navigate a dangerous new reality where his very existence depends on the whims of the commander who saved him.
