[Crossover] When Shen Wu Became the Saniwa of a Corrupted Honmaru

Her heart shattered, the mirror turned to dust. Even as she died, Kanna never knew what freedom was. And yet it was she, with her faint sense of self, little more than a puppet, who managed to cling to life thanks to a shard of mirror that pierced Kagome's eye. Unwilling to disappear, the Shikon Jewel fused with that shard when Kagome made her choice, then transmigrated through the Bone-Eater's Well. In another world, it tried to devour the mirror enshrined at a shrine. By a twist of fate, Kanna was revived as the Mirror Beyond the Clouds. * "I never loved this fleeting world, yet still I linger on. What do I long for tonight, beneath the midnight moon?" When she awoke once more, her pale memories of the past flowed into the mirror, twisting into the image of a familiar face: "I am the wind, the free wind." And so she made a wish: "I want to... bring Kagura back to life." * Kanna, experiencing a powerful desire for the first time, was invited to the Time Government by a fox that spoke like a human. She became a Saniwa tasked with protecting history. Because of her youkai nature, the Time Government also entrusted her with a corrupted Honmaru. This was the first sword Honmaru whose Saniwa was a Tsukumogami. * The Mirror Beyond the Clouds belonged to nothingness. And if it was nothingness, what could bind it? A mirror youkai, yet no youkai. A divine treasure, yet no mere object. No blossoms on the branch, nothing in the heart. Clear as a mirror, untouched by dust. Good and evil, light and shadow: all are dust upon the mirror. 1. All pairings, but I favor SanSani and Tsurumaru. I only write swords I own and know well. 2. The revived Kanna will grow up, and her sense of self will awaken gradually. 3. The swords' personalities are very much my own take, and they're even more overpowered in battle than in Katsugeki. Don't ask. They're ten times stronger when corrupted, and they get a boost from the Shikon Jewel. The swords are the strongest in this story because canon officially says they are gods. 4. Quick transmigration, with one anime series per world, no crossovers. Theme: Find your own heart.
