Makoto Takatsuki and his friends have saved Roses and are now headed to the most prosperous nation on the continentâ€”Highland. They soon arrive in the capital, Symphonia, and despite its grandeur, the city is a hotbed of race and class inequality. When the group bumps into the actively hostile Hero of Lightning, Makoto must weather a vicious battle while simultaneously navigating the limitations of uncontrolled elemental magic. Meanwhile, the Snake Sect is plotting an attack on Symphonia, but the scheme runs deeper than anyone expected: the ruined nation of Laphroaig, which is inhabited by servants of the Great Demon Lord, has become a fierce shadowy presence that lurks beneath the apparent riches of Highland. With our heroes caught in a deadlock against imminent destruction, aid comes from an unlikely placeâ€”the cursed moon priestess of Laphroaig?! Can Makoto trust this exiled priestess and save humanity from being overrun by demons?
