Touko Kirigaya thrives as a popular second-year student and class president at Tsukinomori Girls' Academy, sharing classes with Mashiro and Rui. She wields the guitar in the band Morfonica and crafts all their costumes. Her family's classic kimono shop fuels her fashion expertise, leading her to operate her own T-shirt brand, "TOKO." She lives with her parents and a strict grandmother; the latter forbids guitar practice at home, pushing Touko towards traditional pursuits like tea ceremonies. Standing 164 cm tall, Touko possesses long wavy blonde hair and sharp light-brown eyes. Her signature casual look pairs a light-blue jacket over a salmon hoodie with a vertically printed "BLACK" black shirt, dark blue shorts, multicolored sneakers, a gold pendant necklace, and a braided brown belt. Cheerful and open-hearted, Touko peppers her speech with gyaru slang like "yabai," "maji," and "mikuron." She enjoys immense popularity at school and online, where her influencer persona "TOKO" sets trends. She compulsively snaps selfies everywhere, even mid-performance. Her spontaneous nature often drags others into unexpected situations, and her supreme confidence fuels a desire for a bronze statue at Tsukinomori. Academically, she falters, frequently needing remedial classes and neglecting homework. Her friendships extend beyond the band to include Sayo and Kaoru. She often playfully teases bandmate Tsukushi, sparking light arguments. Her relationship with Rui is notably tense due to clashing personalities, culminating in a major conflict when Rui denies her a guitar highlight in a new song, deeming her skills insufficient. This rejection drives Touko to intensive guitar practice, seeking guidance from Sayo, Kaoru, and Tae to earn Rui's recognition.
