Unnamed thugs

These Unnamed Thugs are prisoners at Deadman Wonderland

Personlaity
The thugs are rude, disrespectful and barbaric individuals. They follow Kōzuji Kazumasa and listen to his every order, presumably out of fear of the man.

Prison Arc
They arrived at Deadman Wonderland on the same day as Ganta Igarashi, in the same prison bus. They are present during Warden Makina's briefing. She asks the new prisoners if they have any questions and the black haired thug asks what size bra she wears, Makina replies that she's a "G" cup. Later, they harassed Ganta when he first arrives at the prison. In the anime, they are killed in the first episode, but survive in the corresponding manga chapter. They were the henchmen of Kōzuji Kazumasa during the manga Dog race show of Chapter 3, surviving the challenge.
