In the fantasy realm of Erion, a girl named Alice discovers enchanted storybooks in her attic that transport her into an intricate tale of competing kingdoms locked in a brutal struggle. The warrior nation of Ragnanival, commanded by the tyrannical Demon Lord Odin, clashes with the sylvan kingdom of Ringford under Fairy Queen Elfaria's rule, both sides desperate to control the Crystallization Cauldron—a devastating artifact that harvests the world's life force to create powerful magical crystals. Looming over this conflict is an ancient prophecy foretelling Armageddon, a cataclysm that threatens to annihilate everything. Five interconnected narratives unfold through the eyes of heroes bound to mystical weapons known as Psyphers: the warrior Valkyrie Gwendolyn, the afflicted Prince Cornelius, fairy princess Mercedes, the enigmatic shadow knight Oswald, and the mysterious witch Velvet, whose interlocking destinies become increasingly entangled as warfare and supernatural fate converge.
