Йошікава Нобору

A student at Holy Forest Academy who didn't have a good time before Eikichi Onizuka arrived, as he was the victim of bullying, mostly from Uehara Anko and her group. He is extremely good with video games and somewhat of an otaku, but proves to be quite handy with making things. Anko's bullying is so bad it makes him attempt to commit suicide twice, both times by leaping off the roof of the school, and both times resulting in him being saved by Onizuka, at the cost of Vice-Principal Hiroshi Uchiyamada's car. The two strike a quick friendship, which works for Onizuka, as Noboru has plenty of items that he wants to "borrow".

His loyalty to Onizuka is by far the strongest, seen when he willingly sells his game collection to help cover Onizuka's debt. While on the school trip to Okinawa, he gets assigned to the same room as Anko and her friends by Onizuka. In retaliation for Onizuka and Noboru's antics, he gets tied up and led away into the dense jungle by the girls, but they all end up getting lost and rely on him for help. Despite the abuse, he saves Anko's life after she falls off a cliff, getting separated from the others. As the rest of the events of the manga unfolds, Noboru begins to enjoy Anko's company enough that she begins to feel affectionate to him.
