Yukio Hidaka
ヒダカ・ユキオ
Riku's classmate and best friend, who attends the same middle school in a coastal city. He loves the animated Gundam series and his knowledge puts any adult to shame. Though he is usually a quiet and reserved boy, he is confident in his skill as a Gunpla builder, and Riku considers him to be a reliable ally as a Diver in GBN.
