Kaede Hozuki stands 157 cm tall as a high school student, with long pink hair usually secured in a ponytail by a scrunchie; she wears it down when relaxing at home unobserved. The anime adds turquoise streaks and reveals her natural reddish hair color, matching Miyo Murosaki's, with the pink being a high school dye choice. Her figure features a narrow waist and large bust, aspects sometimes comedically emphasized in the anime, which she leverages in her fashion to project maturity and femininity. Her personality radiates kindness, care, and strong femininity. She readily assists others, teaching Mihari Oyama, Mahiro Oyama, and their friends cooking techniques and helping select swimsuits tailored to individual preferences and body types. Kaede possesses valued expertise in fashion, hairstyling, makeup, and cooking. She lives by "beauty is pain," choosing bare legs in cold weather. Open-minded towards others' personalities and desires, she adapts advice, like suggesting swimsuits minimizing cleavage. Despite social strengths, she struggles academically, studying at the Oyama house due to limited time from part-time work while pursuing university entrance exams. She shares Mihari's fear of thunder. A significant transformation occurred during middle school, where she blossomed physically and socially, learning to leverage her new assets. References to or images from this period cause extreme embarrassment. After high school graduation and successful college entrance, she announces plans to shed her gyaru image, adopting a more conservative college style: hair worn down, reduced makeup, and long-sleeved sweaters. Relationships define her role. She shares a close, caring bond with her younger sister Momiji Hozuki, extending similar sisterly affection to Mahiro and his friends Asahi Ōka, Miyo Murosaki, and Nayuta Tenkawa, who view her as a respected big sister figure. Her middle-school friendship with Mihari involves supportive study sessions and an incident where an intoxicated Mihari kisses her; Kaede handles this calmly but forbids Mihari from consuming alcohol afterward. She provides massages and emotional support to Mihari during stress. Her development includes mentoring Mahiro through his adjustment to female life, offering makeup and clothing guidance. Key activities involve chaperoning swimsuit shopping trips, hosting joint study sessions with Mihari, and participating in group outings like beach trips and festivals. Her decision to transition away from the gyaru identity after high school signifies personal growth, aligning her external presentation with her evolving self-perception as she enters adulthood.
