In February 2000, Kiana Kaslana's soul fused with that of a transmigrator who had once traveled through the worlds of One Piece and Dark Souls. After her mother, Cecilia, sacrificed herself, Kiana drew the Spiral Sword hidden deep in her consciousness and opened the Dark Souls world bubble anchored inside her.
In May 2007, Siegfried defected from Schicksal. To cover the escape of her father and her younger sister, the experimental subject K423, Kiana stayed behind without permission to hold off their pursuers. At the cost of burning away her own memories, she used the power of the Tremor-Tremor Fruit to unleash two world-shaking punches at Fu Hua and the other Valkyries sent by Schicksal to intercept them.
Three years later, after being gravely wounded and falling unconscious from the backlash of the Tremor-Tremor Fruit's power, Kiana recovered and escaped Schicksal on her own.
Years later, after finally defeating the Soul of Cinder and inheriting the First Flame, Kiana shaped an Ember. With Conqueror's Haki radiating from her and Armament Haki covering her body, a Moonlight Greatsword in one hand and an Izalith Staff in the other, she wielded the flame of pyromancy and used the Six Powers as she stormed Schicksal's headquarters alone. Once again, she stood before the source of all tragedy: Schicksal's Archbishop, Otto Apocalypse.
Kiana: "Your Excellency, you seem like you'd be very hard to burn."
Otto: "Don't come any closer!"
