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.

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. Enki had built an underground prison beneath Building 5, and has a secret archive room which has data on certain dangerous criminals, later discovered by Jyugo, that Enki was aware that Jyugo was part of a human experiment. After betraying his co-workers and killing an inmate, later revealed to be Elf, he was apprehended and arrested by his co-workers. He now resides in the underground prison of Building 5. 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.

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.

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.

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.
