In a world where Nexis, a powerful energy, is predominantly awakened in women, society has become female-dominated, while men, with only a 30% chance of developing this power, are viewed with suspicion. Ren Amagiri is one of the rare men to awaken Nexis, but in a world that despises men with such abilities, he becomes a target of envy and prejudice. To protect him, his parents disguise him as a girl, altering his identity and sending him to the prestigious Reijō Academy, a school where women are trained to become powerful warriors. Now, as Yuki Amagiri, Ren must live under a false identity, enduring the disdain of his peers and the pressure of rigorous training. However, some classmates grow obsessed with him, suspecting Yuki's true identity... A revelation that could ruin everything.
