Tsubame Koyasu

Tsubame Koyasu is a supporting character in the Kaguya-sama wa Kokurasetai series. She is a graduate of Shuchi'in Academy and one of The Impossible Girls who was the vice captain of the Cheer Club and the former chairman of the Culture Festival Committee. Tsubame is considered as "one of the prettiest girls in the school" (by Yu Ishigami and Erika Kose) and "the madonna of the third-years" (by Kaguya Shinomiya) with pink hair that has bangs parted 7:3 to the right side of her head where the back portion is tied up to the back side with a black ribbon with hints of purple at the tips of her hair, light pink eyes and a fairly large chest. She is often dressed in a Shuchi'in Academy school uniform or gym clothes and she always wear circle-shaped dangling earrings matching on both ears. After graduation, Tsubame stops wearing her hair ribbon and cuts her hair to chin-length (save for the sidelocks), which Ishigami describes it as making her look more grown up. Tsubame is a kind, caring and cheerful individual who sympathizes a lot with other people, even shedding tears when she saw Yu Ishigami's downcast reaction after losing at the relay race. She always acts in the best interests of people and dislikes hurting them, especially if she feels they are genuine. Because of these characteristics and her undeniable beauty, she is very popular among the seniors and Cheer Club members, especially the guys, who often hit on her or ask her out. She is considered a popular girl and has lots of friends and acquaintances in different year levels and is updated with the latest trends making her always in the circle on new things. She has her own unique slang called 'Tsubamese', which surfaces when she is excited. In this, she talks in concepts rather than words. Rei Onodera stated that the trick to understand it is to feel instead of think. She likes doing physical activities, such as gymnastics, which is the reason why she ended up in the Cheer Club. She was also appointed as chairman of the Culture Festival and was in charge of Shuchi'in Academy's PR team tasked to set up various activities in the festival. Tsubame often has trouble making hard decisions for herself and will seek out advice from others. In particularly stressful situations, she goes shopping to let off steam. Tsubame cries easily as noted by her teammates.
