Virgin Knight: I Became the Frontier Lord in a World Ruled by Women (Manga) Vol. 1

Reincarnated in a world where women dominate the battlefield and men are sheltered, Faust is an anomaly--a rare male knight and celebrated war hero. His unmatched military achievements have earned him fame, but his past-life values make life challenging in this female-led society.
Constantly overwhelmed by the bold advances of powerful women, Faust struggles to maintain his composure. From a barely dressed queen to a voluptuous duchess, the attention is relentless. When tasked with advising the spirited second-eldest princess Valiele on her first campaign, he anticipates an easy mission. But what begins as a simple bandit hunt soon spirals into an unexpected tragedy!
