Reiko Yanagi attends U.A. High School in Class 1-B and later becomes a Pro Hero. Her appearance is pale and slender, evoking a ghost-like quality. She possesses straight, pale silver hair cut in a pixie-bob just above the chin, featuring a sharp side-swept section covering her entire left face. Her half-lidded eyes are a dark Prussian-blue color with pointed lower lashes, complemented by thin brows, dark under-eye bags, and a small mouth with full lips. Her initial hero costume is a light periwinkle-blue kimono with long flared sleeves, a large hood, a white-striped navy band around the upper abdomen, matching boots, and a mask covering her lower face and neck. After a timeskip, her hair grows longer and straighter; her costume changes to a pure white kimono with black trimming, collared black boots, and geta. Quiet and often perceived as emotionless, Reiko holds a distinctive posture with her elbows tucked to her sides and her hands dangling, reminiscent of ghosts or undead creatures – a mannerism aligning with her Quirk, Poltergeist. She enjoys horror themes, frequently reading scary stories online. Moments of timidity surface, like finding Neito Monoma intimidating during his rants about Class 1-A. Despite her reserved nature, she proves helpful, assisting Itsuka Kendo as an attendant during the U.A. School Festival's Beauty Pageant, suggesting an aptitude for fashion. She tends toward cryptic wording, such as referring to Izuku Midoriya as "spooky," requiring clarification by classmates. Her Quirk, Poltergeist, grants telekinetic control over nearby objects with a weight limit roughly equivalent to an average human (approximately 137 pounds). She levitates and propels multiple objects simultaneously for projectile attacks. Her combat effectiveness relies heavily on coordination; during the Joint Training Battle, she collaborated with Yui Kodai (who enlarged objects) and Nirengeki Shoda (who increased their speed and impact), enabling long-range assaults without revealing their team's location, though Ochaco Uraraka ultimately defeated her. In the Final War, Reiko and Yui supported Mt. Lady by levitating and enlarging weapons against Gigantomachia until All For One overpowered them. Reiko demonstrates tactical intellect, identifying Midoriya as a primary threat due to his enhanced Quirk capabilities and mobility before their match. Her background includes an affinity for browsing horror stories online. Her chosen hero name, "Emily," references the 2005 horror film *The Exorcism of Emily Rose*. Her surname, Yanagi, means "willow," while her given name, Reiko, incorporates katakana symbols for "rei" (霊, "spirit" or "soul") and "ko" (子, "child"). Reiko debuted during the U.A. Sports Festival and participated in the Forest Training Camp and Joint Training arcs. She later aided in the Paranormal Liberation War, contributing to the Gigantomachia suppression effort. Eight years after the Final War, she has fully transitioned into a professional hero role.
