Golgorosso is a large man who wears a thick green academy uniform.
Golgorosso does not descend from a noble family, so he had to work hard to enter the Academy. He selected Eugeo because he did not descend from a noble family either, while Sortiliena Serlut had already selected Kirito.
During Kirito and Eugeo's first year in the Academy, Golgorosso was the 3rd ranked elite swordsman in the Master Sword Academy, in each placing tournament losing against Sortiliena Serlut. Golgorosso is Eugeo's mentor during Eugeo's first year in the Academy and is known for making Eugeo take off his clothes so that he can look at Eugeo's muscle development.
Near the end of the school year, Golgorosso watched Kirito's match against Volo Levantein and was later invited to Sortiliena's room to celebrate.
Balto Sword Style
Golgorosso uses the Balto-style, which gains its power from the body muscles, and he empowers his sword with the hours of dedication and training he has done to reach where he is now.
Although Golgorosso is not a noble, he does have a family name, meaning that his family has to be famous enough to be allowed a family name, as most non-nobles were not even allowed to have one.
