Hirota Hiroshi is a cyclist with little experience, but seems highly knowledgeable.
He is introduced talking with a young girl beside the road during the First-Year Welcome Race, when Imaizumi Shunsuke and Naruko Shoukichi rush past him. He can tell they are skilled. Wanting to impress the girl he's with, he spots Onoda and mounts his bike to give Onoda Sakamichi "advice", as Onoda does not appear too skilled to him. Onoda, however, surprises him by rushing past him as well, focused on chasing his friends. Later, at the Inter-High, both Hirota and the girl are watching the race from the beginning of the only downhill section of the Fuji Azami Line, and were astonished by the pace set by Imaizumi and Midousuji, who themselves are violently bumping each other to block each other for the lead.
