Імаїдзумі Шюнсуке

Imaizumi is a high school freshman and a member of the Sohoku High Bicycle Club. He is an all-rounder and a logical thinker, also adored by many girls due to his good looks. His dream is to become the fastest cyclist in the world. He has a fierce rivalry with Naruko, because of his sprinting abilities and his overall attitude, and sets his goal on Kinjou, who he currently sees as his biggest obstacle as Kinjou uses this as his mentor to push Imaizumi. He treats Onoda friendlier than his other teammates as he sees his potential, and wants to see where Onoda's cycling career takes him.

In the training camp, Kinjou takes away his gearshift, so he would have to rely more on his physical abilities than his technical skills and understanding. (Source: Wikipedia)
