 * Jūgo (ジューゴ)
 * Inmate number 1315. He is of Japanese descent, has black hair with red streaks at the end, and has heterochromia; his left eye is green and his right eye is violet. He is confident, cheerful, impulsive and gets bored easily. He is skilled at picking any kind of mechanical or electronic lock. The sole exceptions are the shackles on his neck, wrists and ankles which were placed on him mysteriously when he was asleep by a guard with a scar on the back of his neck. His father was inmate number 610 at Nanba Prison and known as "the shame of Nanba Prison". He hates the guard who placed the shackles on him, and longs to find him and have them removed. He states that he has to be in Nanba Prison as he has been to all other prisons. His name just means 'fifteen'.

 * (ウノ)
 * Inmate number 1311. He is of British descent, has a long braid, wears a hat, loves women and gambling, and often has a pair of cards on hand.

He is kind and outgoing (to the point of being silly) but can be blunt. He is often the one who keeps the others in line when Hajime is not around, and Nico jokes that he is starting to act like he is their mother. He is also very loyal to Jyugo, whom he claims saved his life and gave him his freedom back. After Jyugo is beaten within an inch of his life by Hajime, he holds a deep anger against Hajime, stating he could never come to like prison guards. He broke out of his previous prisons because he had dates to attend.

 * Niko (ニコ)
 * Inmate number 1325. An American effeminate short male with green hair and bandages on the right side of his body, predominantly on the right side of his face. He has a chain ball shackled to his right leg. He grew up in the slums, where he was a drug mule, and has escaped multiple prisons primarily because they tried to inject his medicine into him. He is calm at Nanba Prison as the medicine is taken orally and is flavored. Drugs have an unusual effect on him and rather than incapacitate him, they have alternate side effects. He rarely takes anything seriously and is rather childish and happy-go-lucky. He is a huge anime fan. In the second season, it is revealed why he is so ill and dependent on medication. As a child, a drug gang used him to test their products, which made him develop several unknown illnesses. After being arrested, the doctors at the first prison he was sent to performed painful, invasive medical experiments on him under the guise of trying to help him get better, which only made him more ill. After spending years locked in the prison infirmary, he eventually sunk into a deep depression and wished that he could die, until Jyugo freed him and helped him develop an interest in life again. In episode 21, it is revealed that he has a violent split personality that will emerge if his health problems are not kept under control with his medications, but he is unaware of its existence.

He also was often seen with Samon by his side. According to Liang and Upa, Enki used to be in charge of a prison in China where he cruelly beat up inmates to become stronger. Upa was nearly killed by his abuse and Liang was terrified at the thought that he would be next but Enki was transferred to Nanba Prison. Formerly the supervising officer of Building 5, he was well-respected and admired by the many fellow guards and even inmates throughout Nanba Prison. He was also considered indispensable to Building 5 and Nanba Prison. However, according to Liang and Upa, Enki had continued to cruelly beat up inmates in Nanba Prison which causes inmates to fear Enki.

Some time ago, Enki faced someone with blades similar to Jyugo. The mysterious person managed to injure Enki's left arm and Enki called him a monster. Since then, Enki was searching for him with the intent to kill him, as he believes the man is too dangerous to let live. During the second season, he is released by Inori and Houzuki. The three join forces with Ruka and Hachiman, who have all allied themselves with Enki. The five proceed to carry out a plan to capture all of the inmates and supervisors, although it is not known exactly what Enki's ultimate goal is. While trying to capture the inmates, he sees Jyugo and plans to kill him, as he believes that he is the man with the blades who attacked him.

 * (ムサシ)
 * Inmate number 4634. He was born with a rare disease that keeps his body temperature much higher than normal and allows him to manifest flames. He would learn to live and adapt with the disease.

He has since been determined to get revenge against that scientist.

 * Ryan (リャン)
 * Inmate number 0502. A master martial artist who can usually be found training. He willingly joined the mob as a young boy to save the life of his teacher, who he witnessed nearly being murdered by the mob for refusing their demands. He was supposed to be an assassin for the boss, but he believed that killing was a sin, and instead used a drug created by Qi to knock his targets out while making them appear to be dead. Eventually he was found out by the boss, who rounded up all the people Liang had spared and forced him to watch them be killed before being brutally tortured himself. When the organization was shut down by the police, he was arrested and sent to jail in China. After a short period there, he was transferred to Nanba Prison. He was severely depressed and disillusioned with martial arts by this time, as his years in the mob had damaged his ideals and left him thinking that he could never be a good person after what he had done. Eventually, he was able to rediscover his passion after Samon took him in and began training him. He considers Samon to be his mentor and wants to become stronger so that he can be useful to the guard, who he credits with giving him the will to continue living.

 * (ウパ)
 * Inmate number 0558. Upa is a powerful qigong master and has a talisman attached to his head to restrict his qi usage. He was kidnapped by the crime syndicate Liang used to work for when he was a child because as the most prodigious member of a powerful clan, his internal organs were worth a great deal of money on the black market. He stayed and worked for the group willingly, as they had promised to return his organs if he proved useful to them. However, it is revealed in season 2 that the organs he received were not his own, but Qi's, who had had his organs transplanted to Upa after he began dying due to his body shutting down. After he was arrested, he was sent to a prison in China, where he unfortunately became a victim of Enki's cruel abuse. However, during this time, he also met Samon after the guard was able to put him back in contact with his family, who had been told by the mob boss that he had died. He highly respects Samon because even though the guard claimed that he was just doing his job, he was the first person to show him any sort of kindness or respect in years. His aim is to finish serving out his sentence and attempt to begin a new, better life alongside Liang and Qi.

 * Chī (チィー)
 * Inmate number 0571. A prisoner famous for his skill at making drugs and poisons. He resides in cell block five with Liang and Upa. He is rather lazy, and can usually be seen relaxing or sleeping in the background, to the point that Liang and Upa often call him "lazy trash". He was forced into working for the same people who had taken Liang and Upa to save his own life. He initially was unconcerned about the mob's immoral actives, as he was focused on self preservation, but came to hate them after witnessing the boss abusing Liang and Upa. Unbeknownst to Upa, he even gave him some of his own internal organs to save the young boy's life. Eventually, he discovered that his products were being modified to maim and kill the people who used them and, following his arrest, swore that he would never manufacture drugs or poisons again, as he had come to believe that his talents could only hurt other people. During this time, he also lost his ability to trust others. When he was transferred to Nanba Prison, however, he eventually was able to take up his trade again after being encouraged by Samon. He came to respect Samon for his honesty and kindness, and hopes that he will be able to repay the guard before he is released.

Unbeknownst to Upa, he even gave him some of his own internal organs to save the young boy's life. Eventually, he discovered that his products were being modified to maim and kill the people who used them and, following his arrest, swore that he would never manufacture drugs or poisons again, as he had come to believe that his talents could only hurt other people. During this time, he also lost his ability to trust others. When he was transferred to Nanba Prison, however, he eventually was able to take up his trade again after being encouraged by Samon. He came to respect Samon for his honesty and kindness, and hopes that he will be able to repay the guard before he is released.
