|“||It's a waste not to try something that seems fun||”|
—Tsubame Koyasu, Vol 12. Chapter 116, Page 12
Tsubame is a young girl with her bangs parted 7:3 to the right side of her head with the back portion tied up the back side with a ribbon
Tsubame is a kind and cheery individual. She sympathizes a lot with other people, this led to her shedding tears when she saw Yu's downcast reaction at his loss at the relay race.
Tsubame is one of the members of the Cheer team that helped Yu get accustomed to teamwork and other people. Her kindness led to Yu being one of the many to have a crush on her but this has yet progressed to anywhere.
