Dual Sword Liberator

Yakumo Ryuu, a first-year student, is asked by Nanami Yuki to visit the school swimming pool one evening. In an academy town inhabited by individuals with unusual abilities, the student council president has locked down the school, placing all students under house arrest. Freedom can only be restored by defeating five power users in duels. Those who resist are labeled heroes, but Ryuu, whose ability allows him to create a doppelganger within three meters, is not suited for combat and remains among the onlookers. One night, Ryuu finds a sword on campus, and from that moment, the academy's power structure is upended. He becomes a rebel, wielding both a sacred and a demonic sword, and the conflict within the academy begins.
