Cecillia Fujiwara, a 15-year-old girl of French-Japanese descent, stands at the crossroads of a life once filled with the simplicity of youth and the complexities of a destiny she never imagined. Her adoption by a group of adventurers brought her a semblance of normalcy, but that tranquility shattered on the day her life transformed into that of a puppet. Now, Cecillia's existence is confined within the cold embrace of a museum, her once vibrant eyes replaced by the lifeless gaze of a puppet, fixed eternally on the wall before her. Yet, fate had more in store for her when she was unexpectedly transported to a world ruled by puppets, where she was crowned the Puppet Princess of the Puppet Kingdom. The puppets' sinister ambition to eradicate humanity and repopulate Earth with their version of 'Perfect Humans' places Cecillia at the heart of a moral dilemma. Torn between her loyalty to her human family and friends and the allure of her new role, Cecillia's puppet mouth opens and closes in a hauntingly synthetic voice as she accepts the crown, her strings trailing behind like the remnants of her past life. Her journey to save Earth is fraught with challenges as she navigates the politics of the Puppet Kingdom, seeking allies among the puppets who question their leader's genocidal vision. Cecillia's intelligence and empathy become her greatest assets as she works to undermine the kingdom from within, all while grappling with the fear of losing her humanity. Her unique trait, a soft, almost imperceptible French accent that lingers in her synthetic speech, serves as a constant reminder of her origins. As she maneuvers through the puppet society, Cecillia's resolve is tested by the allure of power and the fear of betrayal. Her story is one of resilience, as she fights to protect her loved ones and preserve her humanity, even as she becomes more puppet than girl. The conflict between her duty as a princess and her desire to return to her human life drives her narrative forward, culminating in a climactic confrontation that will determine the fate of both worlds.
