Nakamura Kyoujirou was looked down upon by others as a 'stray dog' due to his being orphaned at a young age. First introduced in Episode 107, he was orphaned as a child and was caught by members of the Mashiroi Group, a yakuza organization, while on a 'crime spree'.
The leader of the group, Mashiroi Kaguzou saw Kyoujirou's scowling tough look and laughed, saying he would like to see that stern look disappear one day. Kyoujirou was then accepted into the group and became the bodyguard of the leader's young son Mashiroi Utsuzou.
Once while out walking, Utsuzou was attacked and the young Kyoujirou used his body to protect his charge, and ended up with a big cut across his left eye as a result. Upon returning home, the crying son rushed into his father's arms only to see the father rushing over to hug the injured Kyoujirou in relief that he was all right.
One adult had always emphasized to the young Kyoujirou that he must be a loyal person right to the end, much like the Komainu, a mythological dog-like creature steadfastly guarding the gates of the temple.
Black short hair, fringe swept to the right. He has a vertical on the left side of his face, acquired in his childhood while protecting his benefactor's son. Typically seen in a purple yukata worn loosely
Lone wolf personality who tries to carry all burdens alone.
Rival gangs believed the rumour and plotted to oust him for his 'seeming' treachery and more likely,to take over the group's leadership. Under the guise of a ceremony to officially recognise Kyoujirou as the Mashiroi group new leader, the rival gang laid in ambush to get rid of Kyoujirou. While escaping the gangs together with Gintoki, Kyoujirou was mortally wounded by a gun shot, and died with a peaceful look on his face next to his benefactor's tomb in the drizzling rain.
