Hitomi Kanzaki, an ordinary high school track star plagued by vivid premonitions, finds her world upended when a mysterious boy named Van Fanel materializes from the sky alongside a towering, mechanical dragon. As Van slays the beast, a blinding pillar of light engulfs them both, transporting Hitomi to Gaea—a surreal, breathtaking world where Earth hangs like a pearl in the bruised purple sky.Hitomi learns that Van is the young king of Fanelia, a peaceful nation recently devastated by the ruthless Zaibach Empire. Led by the enigmatic Emperor Dornkirk, Zaibach seeks to rewrite the planet’s destiny using forbidden technology and the legendary, dragon-powered mecha known as Guymelefs. Driven by grief and a desperate need for vengeance, Van activates Escaflowne, the ultimate Guymelef bound to his royal bloodline.Seeking refuge, Hitomi and Van ally with Allen Schezar, a charismatic knight from Asturia who bears a striking resemblance to Hitomi’s Earth crush. Together, they embark on a perilous odyssey across Gaea's fractured continents. Along the way, they recruit Merle, a cat-girl devoted to Van, and encounter Princess Millerna, whose political ambitions complicate their alliances. As Hitomi’s precognitive powers violently awaken, she realizes she can peer into the strands of fate, inadvertently becoming a pawn—and a target—for Dornkirk’s grand design: the "Project of Absolute Fortitude," a machine designed to strip humanity of free will and eliminate sorrow.Tensions peak as the group battles the Zaibach commanders, most notably Dilandau Albau, a sadistic and volatile warrior whose tragic past mirrors Van’s. During the harrowing war, shocking revelations emerge: Allen’s lost childhood friend, Folken, is actually Van’s older brother, who survived their kingdom's destruction only to become Zaibach’s chief strategist. Folken’s manipulation drives a wedge between the heroes, culminating in the apparent destruction of Escaflowne and the capture of Hitomi, whose emotional energy is vital to power Dornkirk’s reality-altering machine.Imprisoned in the floating fortress of Desires, Hitomi resists Dornkirk’s
psychological manipulation, refusing to let him dictate humanity's future. Van, having survived and unlocked Escaflowne’s true, angelic combat form, launches a desperate
rescue mission alongside Allen and Folken, who has finally turned against Dornkirk's tyranny. In the climatic confrontation, Van and Hitomi combine their wills to shatter the fate-altering device. The machine collapses in on itself, dismantling Zaibach's empire and freeing Gaea from engineered destiny. With the war finally over, Folken sacrifices himself to ensure peace, while Hitomi is forced to make a heartbreaking choice. Utilizing the lingering magic of the portal, she steps back through the veil, returning to Earth carrying the bittersweet memory of her epic adventure and a profound love for the dragon-king she left behind.
