Go was a large overweight boy, he had big teeth short black curled hair with sideburns, and large bags underneath his eyes. He wore his school uniform however but it was somewhat ragged.
Go was a rude and thuggish boy, and while not evil he was a very unlikable kind of person.
Go was a member of a gang, at one point he, Ken and Dosu-Roku follow the girl Miki Makimura and her friend Akira Fudo home taunting them. Miki retaliates and insults them before slapping Ken and Go in the face. However Dosu-Roku grabs her arm now furious, he tells Go and Ken to block the path for Akira. They are saved by the sudden arrival of Ryo Asuka who chases the gang away.
Later after Akira had become the titular Devilman, Go, Ken and Dosu-Roku again attack Miki and Akira however this time Akira steps in and beats the silly in mere seconds.
