In a modern world shaped by Quirks—innate superpowers that shape careers and society—Aoi Kinzuru is a 16-year-old hero-in-training at a metropolitan hero academy. Born with baby-blue skin and delicate antennae, her Quirk, Silken Resonance, lets her sense minute vibrations and spin controllable silk-like threads. Raised in a coastal town by her grandmother, Aoi learned sewing, jewelry-smithing, and practical gadget-making, turning textiles into lightweight rescue gear and comforting items. Her mature, round appearance and braided gray pigtails give her an older-sibling air; she uses scarves, hairpins, and knee-high socks as functional tools in the field. Often underestimated, she specializes in support and rescue tactics—binding hazards, stabilizing structures, and sensing trapped civilians. Soft-spoken but unshakable, Aoi aims to show that careful craft, empathy, and steady resolve are as heroic as flashy powers.
