Tatsumi's Mirror: The Journey of the dancing fox in the winter's ash

Synopsis

a frostbitten nation rebuilt from the ashes of war, a secret military force known only as The Shade conducts forbidden experiments to harness the power of ancient Mirror Spirits—divine foxlike beings sealed in glass since antiquity. Their most successful creation is a three-month-old test-tube infant: Tatsumi, the only child who survives fusion with the legendary Kagami-no-Kitsune mirror shard. Before The Shade can claim their weapon, two retired operatives—an elderly couple named Hanae and Daigo—risk their lives to steal the infant away and raise her as their own. Sixteen years later, Tatsumi grows into a vibrant, chaotic, music-loving girl who fights using a custom guitar with a sword hidden in its neck. On her left shoulder lies the fused mirror shard—glittering beneath skin like silver glass. It hides the presence of Kitsu, the fox spirit bonded to her soul… a spirit that acts on its own free will, awakening whenever Tatsumi is in danger. Life changes when Rei, a young Shade hunter, is sent to retrieve her. His mission begins as a hunt—but the more he witnesses Tatsumi’s warmth, her music, and her unyielding spirit, the more he questions everything he believes in. As the two clash, bond, and grow closer, The Shade launches a full-scale operation to reclaim the “lost divine weapon.” Haunted temples, frozen cities, and ancient mirror ruins awaken as Tatsumi’s powers evolve. Hidden enemies rise from the shadows. And the slumbering Fox Mirror Spirit grows restless, warning her of a deeper truth… one that could unravel the nation itself. Caught between the past she never chose and the family she loves, Tatsumi must learn to master the fox within and discover whether she is a weapon—or a girl destined to illuminate the darkness.
