The Trial of Salvation begins in the kingdom of Elenor, where a grim prophecy foretells the reincarnation of the Demon King in two years, threatening the realm with total destruction. As King Lucas Elenor discusses the impending doom with his children, Princess Rose and Prince Shiki, the need for heroes becomes clear. Despite the forbidden nature of the act, the kingdom resorts to an ancient, forbidden ritual to summon warriors from another world to help defeat the Demon King. Meanwhile, in modern-day Tokyo, three individuals—Masha Youkimora, Hiori Yamamoto, and her older brother Haru—are unexpectedly whisked away from their normal lives by a powerful magical force. They find themselves transported to the Holy Temple of Elenor, where King Lucas reveals they have been summoned to save his kingdom. Despite their confusion and disbelief, the trio is informed that they are not just ordinary people—they possess latent powers bestowed upon them by the gods, powers that they must unlock to prepare for the coming battle. With no choice but to comply, the group agrees to help, but only under the condition that they will be sent back to their world once the war is over. Their journey begins as they are escorted to the Royal Palace to recover and train for the trial that awaits them. This chapter sets the stage for an epic adventure, filled with the promise of growth, conflict, and the uncertainty of what lies ahead in a world that is both foreign and fraught with peril.
