Osamu Shima

Another of Katsutoshi Hirota's cousins, who joins Senkawa High School at the same time as Ohtake, a year junior to Hiro. Was sent to sabotage the Senkawa High School baseball team during the regional tournament. A former track and field sprinter, with a bad reputation of sabotaging the competition beforehand. Possibly the fastest person on the team. [source: AdachiFan]
