Used to play for the Hakusan Angels in primary school until Hideo replaced him. He turned to soccer instead, his athletic ability helping him. He tries to persuade Haruka to give up on her baseball ambitions, but later joins the baseball team in order to get closer with Haruka. Kine acts as leadoff batter and center fielder, and was also pitcher when he was in the Hakusan Angels. As a homage to Kakefu, he does left-handed baseball swings. As Haruka and Hiro's relationship gets better, he plots with Miho in order to split them up.
