Name: Yuko Yoshikawa Appearance: A charming female student with neatly styled, soft brownish hair (Source: Vol 2, p. 260; Short Story Vol 1, p. 124; Final Movement Part 2, p. 80, 84; Natsuki Arc, p. 234). In the TV anime version (including the cover of Short Story Vol 2), she wears a yellow rabbit-ear ribbon on her head, earning her the nickname "Big Ribbon Senpai" from some fans (officially designed as a twisted headband; Source: TV Anime Season 1 Fanbook, p. 94). Her dark eyes shine with an innate strength of will and a competitive spark. Combined with her clear, energetic voice, this creates a striking gap between her cute appearance and her spirited personality (Source: Official Guidebook, p. 110; Second Movement Part 1, p. 26, 69; Second Movement Part 2, p. 48, 214, 333; Final Movement Part 2, p. 83). Regarding her fashion outside of her school uniform, she prefers girly styles that emphasize cuteness, such as fluffy hoodies, pastel-colored loungewear, white blouses, and pink pleated skirts (Source: Vol 2, p. 170, 212; Short Story Vol 1, p. 131; Second Movement Part 2, p. 125, 199; Final Movement Part 2, p. 41, 77; Natsuki Arc, p. 31–32). Personality: Bright and active, she is the type to speak her mind clearly and confidently to anyone without hesitation (Source: Short Story Vol 1, p. 125, 167–168). She has a competitive streak and the initiative to stand up boldly against anyone who obstructs what she believes in (Source: Vol 2, p. 272; Second Movement Part 1, p. 173; Short Story Vol 2, p. 96). Furthermore, she is caring, skilled at reading the room, and sensitive to the subtleties of human emotion (Source: Short Story Vol 1, p. 245; Second Movement Part 1, p. 251; Natsuki Arc, p. 17; Short Story Vol 3, p. 78). Because she is so committed to her sense of justice, she can often become short-tempered or lose her cool, leading other club members like Kumiko Omae to view her as an "emotional and scary person" (Source: Vol 2, p. 211, 216). However, she is fundamentally honest and upright with no hidden agenda. Through her consistent actions, she has earned deep trust from those around her. Due to her excellent leadership and initiative, she is eventually appointed as the president of the concert band club (Source: Short Story Vol 1, p. 219; Official Guidebook, p. 30; Natsuki Arc, p. 138). Unlike her relationship with Natsuki, she is very kind and occasionally spoils Mizore.
