Kaede Otori, a student at Itan Private High School, embodies a remarkably relaxed and perpetually distracted nature. Her long, dark green hair flows into a low ponytail secured by a bow, accented by a whimsical ahoge and side strands fastened with small ties. Slender thread-like lines define her softly closed eyes, complementing a constant gentle smile that exudes tranquility. She layers her school uniform with a cardigan under the jacket and pairs it with knee-high socks. Kaede’s speech and movements unfold at a leisurely pace, often leaving her trailing during conversations or activities. While this occasionally sparks confusion, it fosters a patient environment for shy classmates like Komi Shouko, who find solace in her unhurried interactions. Her tendency to wander unnoticed compels her vigilant friend Nene Onemine to clasp her hand during outings, ensuring she stays anchored. Raised in a sprawling mansion where she sometimes loses her way, Kaede inherits her airheaded tendencies from her mother, who once embarked on an unannounced weeklong visit to a neighbor. Despite her spaciness, Kaede displays quiet thoughtfulness, such as inviting Komi to collaborate on festival tasks—a gesture that organically eases Komi’s social anxiety. Though timed exams challenge her, ballet-trained flexibility shines in physical tests. Her hobbies mirror her slow rhythm, like losing days entranced by looping fireplace videos. Dubbed the "Bibi-tto" duo with Onemine due to shared surname characters, she frequents Onemine’s home, adored as "Big Sis Kaede" by the younger siblings. During school events, including a New York trip requiring careful monitoring, Kaede balances her quirks with subtle inclusivity, gently weaving isolated peers into group dynamics without fanfare.
