Shirogane

Born with the name Eleanor, she became the immortal 'Shirogane' after drinking the legendary Water of Life. Entrusted by the late Saiga Shoji to watch over young heir Masaru, she commands the formidable string puppet 'Harlequin' to battle relentless automata threats. Initially cold and expressionless as a doll herself, her journey alongside Masaru and Kato Narumi slowly reawakens her buried humanity, bringing warmth and genuine smiles back to her face. As the linchpin connecting a century-spanning destiny, she stands as a selfless pillar of love protecting those she holds dear.
