A new chapter of Sailor Prism begins here. The Rose Demon King Brothers, threatening the core of Earth, attack the planet with massive tentacles. To save the world from this crisis, three Sailor Warriors rise up: the Moonlight Warrior Sailor Priest, the Fire Warrior Sailor Wizard, and the Water Warrior Sailor Medium. Transforming to fight, they defeat the Demon King's minions one by one—yet behind their victories lies a trap designed to drag them into hell. As the battle progresses, the trio gradually lose trust in each other and begin acting separately. Each time they face the Demon King, they are met with degrading words, violent assaults, and the worst possible attacks, driving their minds and bodies to the brink. Yet their only hope remains: to rebuild their bonds, unite once more, and destroy the Demon King together.
