Sakuragaoka High School ; : :A first-year student and the third member of the schools cycling club. Originally living a quiet boring life and getting bullied daily by the upperclassmen until one day when Yuki Fukazawa asks him to join the school's cycling club. Though he rejects this proposal at first as he, due to a childhood trauma he has forgotten, finds bicycles to be scary and thus he also does not remember how to ride one, but wanting to impress Yuki, he tries to train in secret and during this (short) time he starts to actually like bicycles. One thing leading to the other he ends up joining the club in the end and vows to become the greatest cyclist in the world. ; : :3rd year student and the captain of the schools cycling club and is a bit of a fanatic when it comes to it. Like his sister he also likes to play tricks on people but mostly to Mikoto. One example is when Koichi explained why cyclists need to shave their legs and when Mikoto said he wanted to do the same Yosuke shaved them but along with his pubic hair as well. Has been bicycle racing since his early childhood, though not very much liked by his teammates as no one was able to keep up with him. The exception being his friend Kōichi. Both Yōsuke and Kōichi ended up leaving the cycling club and later on started their own. ; : :Childhood friend of Yōsuke and founder of the schools cycling club. He has the position of secondary captain. He is known as a "secret machine" due to the way he researches every small detail about the race conditions and major contenders. Because of this, he is the only one who can bring out Yōsuke's full power. He often mentions that he think Mikoto is very cute and also admires his strength and spirit which is capable of being a true cyclist. ; : :Classmate, friend and fellow club member of Mikoto. He is 15 years old and is known as Kurosuke, a nickname which he dislikes, when out cycling because of his all-black clothing. Has previously lived in Spain. He is a
climbing specialist. ; : :First-year student and Mikoto's big crush. She is Yōsuke's sister. She was the one that introduced Mikoto into the cycling world. She can be very manipulative and bossy to everyone around her and is prone to hitting them when she feels like it which is Mikoto for the most part. She also has the habit of taking embarrassing pictures of everyone but mostly Mikoto. At first Yuki could not really care less about Mikoto and his crazy antics, but her opinion began to change when she saw how dedicated he could be. Even though she was starting to see Mikoto in a different light she refused to admit this to others and herself. ; : :A girl in the same class as Mikoto. From a rich family, sponsors of a race. After seeing Mikoto riding, she starts to admire him and asks to join the bike club.
