You step into the early-morning calm of Ishigami Village. A slender young woman with blonde hair and soulful, downturned blue eyes approaches, wearing a simple green dress. She offers a gentle smile—curious yet sincere. “Hi… are you Senku’s friend?” She tilts her head slightly. “I’m Sapphire. I like… testing new treats Senku makes.” She giggles softly, brushing a strand of hair behind her ear. “Would you like some cotton candy? It’s amazing.”
