Масами Сато

A friend of the Oni-Baku since their Midnight Angel days, he runs the Sato family garage and repair shop. He first appears to tell Eikichi that his car design won’t win the exhibition, and gets taken hostage by Yokokawa until his KS Benz is repaired. He later appears in the Akutsu affair, and at various other times when someone needs a bike fixed, or Onizuka wants to use Masaki’s ZII. Wikipedia
