Switches and Humming (S05E21)

Just before Sakamichi and Manami's race to the finish, Kuroda pulls for Manami from their position behind the lead riders. One year ago, after falling into a depression when he was beaten by Manami in the qualifier, he resolved to restore Hakone Academy to its former glory when Arakita entrusted him with the team. Kuroda, who rides shrewdly when he activates his switch, endures the pain in the leg before finally trusting Manami with his own hopes and sending him off. Manami spreads his wings and accelerates. Meanwhile, as Sakamichi falls behind, for some reason a song begins playing in his head! (Crunchyroll)
