# Nanbaka

Nanbaka (ナンバカ), also known as Nanbaka - The Numbers, is a Japanese manga series written and illustrated by Shō Futamata. An anime television series adaptation by Satelight aired between 5 October 2016 and 22 March 2017. The title is a play on words, combining the name of the prison, which is the Japanese transcription of the word "number", and the Japanese word "baka" for "fool" or "idiot".

## Premise

The story centers around four young men who are assigned to Nanba Prison, the world's most formidable prison. Jyugo, who attempted to break out of prison and ended up extending his jail time; Uno, a gambling fanatic who likes women; Rock, who likes eating and fighting; and Nico, an ex-drug addict who happens to be an otaku. The action follows the daily lives of the prison's inmates and guards.

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'.

#### Uno (ウノ)

    Voiced by: Tetsuya Kakihara (Japanese); Alejandro Saab (English)
    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 has a great intuition and is able to make bets on what outcome will occur using his observational skills, luck and intuition. 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.

#### Rock (ロック, Rokku)

    Voiced by: Airu Shiozaki (Japanese); Jarrod Greene (English)
    Inmate number 1369. He is American, has a mohawk, wears long feather earnings, and is the physically largest of his fellow cell mates. He loves fighting and eating and is incredibly strong, with only some of the supervisors being stronger. He can be short tempered and impulsive, but cares for his friends, and mostly remains peaceful and happy. He met Jyugo when the other inmate saved him from starving to death in the first prison he was sent to. He escaped other prisons because the food was terrible, but likes the cooking at Nanba Prison.

#### Nico (ニコ, Niko)

    Voiced by: Daiki Kobayashi (Japanese); Justin Briner (English)
    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 is calm and trusting most of the time, although he is known to become loud and obnoxious when annoyed. Despite this, it is eventually revealed that he actually cares for the prisoners in Building 5 quite a great deal, as he helped Upa reconnect with his family after he was arrested in China, and later took Liang under his wing when the inmate was first transferred to Nanba Prison. In season 2, it is revealed that he has an older brother, Enki, who was the former supervising officer of Building 5; Enki was very popular among both the other guards and the prisoners, however, he secretly tortured and abused the inmates in his care, eventually murdering one of them and going on a rampage when his colleagues tried to arrest him. Samon still struggles to comprehend how his brother could do the things he did, and is often taunted by the other guards, who accuse him of being a traitor like his brother was. He becomes irritated when compared to his older brother, and when Hajime is mentioned, he sees Hajime as competition, who was able to capture Enki, while Samon himself hesitated. Enki is a painful reminder of how strong he feels he needs to be.

#### Inori Hakkai (八戒猪里, Hakkai Inori)

    Voiced by: Mitsutaka Itakura (Japanese); Randy E. Aguebor (English)
    The Building 5 Deputy Supervisor under Samon. His face is boar-like, having teeth that mimic such. In season 2, it is revealed that he is actually a mole working for his former supervising officer Enki, when he frees Enki and the prisoners allied with him from their underground cells. He says that he is working with Enki because he wants to see Samon dead, due to how the other guard was chosen as the new Building 5 supervising officer over him; he considers Samon to be weak and cowardly in comparison to his older brother, and detests having to take orders from him.

#### Enki Gokuu (悟空 猿鬼, Gokū Enki)

    Voiced by: Takaya Kuroda (Japanese); Chris Sabat (English)
    He has long white and red hair, with a long ponytail which acts like a tail. He has multiple piercings on his left ear and wears a golden choker. He is usually seen with a serious expression. When he was younger, he was usually seen training. He was strong enough to break a boulder in two with a single strike, mediate underwater and even studied diligently. 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. 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.

    Hajime's cute blonde cross-dressing brother who befriends Jyugo. He has a kind and sweet personality and is very girly. He is more or less the opposite of Hajime; slow, clumsy and non-athletic.

Hajime even goes so far as using him as a blunt weapon or projectile.

He was found by a movie director, who wanted a real shinobi to cast in her film. She tricked the child into believing that she was his long lost mother, come to take him back, and raised him to be an actor and shinobi. When he discovered the truth he tried to head back to his home village, but got lost and ended up getting arrested for trespassing. After escaping the prison, he was recaptured and sent to Nanba Prison.

#### Musashi (ムサシ)

    Voiced by: Yoshimasa Hosoya (Japanese); Jason Liebrecht (English)
    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. However, when he went to college in Germany, his condition went out of control. Fellow student Elf took advantage of the situation by framing him for numerous arson crimes in order to make it acceptable for him as a convicted criminal to be used as a test subject. In an act of rebellion, he burned the lab, but his power was suppressed by the Man with the Scar, which led to him being sent to Nanba Prison where he finally found someone who believed his story in Kenshiro. He has since been determined to get revenge against that scientist.

#### Liang (リャン, Ryan)

    Voiced by: Yuuki Fujiwara (Japanese); Blake Shepard (English)
    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.

#### Upa (ウパ)

    Voiced by: Yū Kobayashi (Japanese); Aaron Dismuke (English)
    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.

#### Qi (チィー, Chī)

    Voiced by: Genki Okawa (Japanese); Gabe Kunda (English)
    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.

| Four inmates (Jyugo, Uno, Rock and Nico) attempt to escape from the world's most secure prison on a remote island called Nanba Prison. Although they evade various booby traps, they are eventually recaptured by Building 13 supervising officer Hajime Sugoroku waiting outside the front entrance and returned to their cell in Building 13. Jyugo, Uno, Rock and Nico come to the conclusion that life at Nanba Prison is not that bad. After learning of a blonde lady visiting the prison, Jyugo, Uno, Rock and Nico break out of their cell and rush into the visiting room. It turns out that this blonde lady is actually Hajime's younger cross-dressing brother Hitoshi Sugoroku. Prison warden Momoko Hyakushiki arrives back at Nanba Prison and warns Hajime to treat Jyugo with caution, as it is revealed that Jyugo's father is known as the "eternal fugitive". Meanwhile, Jyugo escapes from his cell again, telling Hitoshi that he vows to find the Man with the Scar, a scientist who is responsible for placing irremovable black shackles on Jyugo's neck, wrists and ankles. ||||

| At the warden's office, Momoko tells Hajime that Jyugo, Uno, Rock and Nico are described as diabolical escape artists, but Hajime hides the fact that the four inmates have caused problems. When Hajime leaves the warden's office, it is shown that Momoko secretly has a crush on Hajime. Soon after, Hajime finds Jyugo sleeping in the night duty room, as Jyugo claims that Rock snores, Uno grinds his teeth and Nico laughs in his sleep. Hajime later assigns the prisoners of Building 13 to the woodworking department for handcrafted furniture. However, Hajime gets upset when Nico and Uno carve wooden dolls while Jyugo and Rock assemble a chest of drawers with ejecting drawers. Suspense builds as Hajime makes his way to the warden's office in order to give Momoko a dossier of Jyugo, Uno, Rock and Nico. Momoko notices that there is no mention of the four inmates attempting to escape Nanba Prison. Hajime details Nico's drug abuse, Rock's obsession with fighting and food, Uno's compulsive gambling and dating and Jyugo's hobby of escaping prison. It is concluded that Jyugo, Uno, Rock and Nico do not desire to escape from Nanba Prison since they are comfortable there. ||||

| After Hajime learns that Jyugo, Uno, Rock and Nico are constantly bullying prison guard Seitarou Tanabata, Hajime suggests for Seitarou to exploit the weaknesses of the four inmates. At the warden's office, Momoko informs Hajime that a new inmate will be transferred to Cell 13 with the four inmates. Soon after, the four inmates are introduced to Tsukumo, who claims to be a ninja. Tsukumo challenges Jyugo to a prison escape contest, while Uno, Rock and Nico serve as judges. However, they are caught by Hajime near the courtyard, and Tsukumo ends up trapping himself within his scattered leaves and makibishi. Tsukumo will be transferred to Cell 11 as a result. Seitarou and Building 13 deputy supervisor Yamato Godai assign Jyugo, Uno, Rock and Nico to clean and decorate their cell in preparation for New Year's Day. Meanwhile, Hajime and Building 5 supervising officer Samon Gokuu are assigned to clean the warden's office, where Momoko is captivated by Hajime's thorough work.

| In an arena, Momoko announces the New Year Joint Cooperation Tournament, where prisoners and officers from each building are formed into competing teams across five events. Chief broadcaster Mitsuru Hitokoe gives play-by-play commentary. During the first event called Kakizome, Jyugo displays terrible penmanship in calligraphy, yet Hajime and Yamato both present winning scripts. During the second event called Mochi Pounding Daruma Drop, Rock fights Building 5 inmate Liang while Yamato battles Building 5 deputy supervisor Inori Hakkai. It is revealed that Liang trained tirelessly to fight against Rock, who was Liang's former cellmate. Rock wishes to have a stone oven as his prize. Using their fighting prowess, both Rock and Yamato easily defeat Liang and Inori, thereby winning the match. During the third event called Hyakunin Isshu, Seitarou and Uno are up against Building 3 supervising officer Kiji Mitsuba and Building 5 inmates Trois and Honey in a game of competitive karuta.

During the fourth event called Top Spinning, up to three participants from each team have to spin a giant top and knock the other team's top out of the ring. Hajime competes against Samon, while Kiji competes against Building 4 supervising officer Kenshiro Yozakura. A grudge match starts between Samon and Building 5 inmates Upa and Qi against Hajime and Nico. When Upa and Qi attack Hajime, Nico intervenes while Qi decides to sit out. Hajime is able to deflect attacks when Samon swings his staff. Upa is amazed when Nico begins copying attacks from Liang's martial arts and Upa's qigong. Nico wishes to have the latest video game console as his prize. Hajime and Nico eventually emerge victorious against Samon and Upa. Meanwhile, Kiji is defeated by Kenshiro in their match. ||||

In the infirmary, Samon and Inori discuss that Qi is a pharmaceutical chemist who can make both drugs and poisons. During the fifth and final event called Sake Barrel Opening, Hajime and Jyugo are forced to face Kenshiro and Building 4 inmate Musashi. The fight commences as it is revealed that Musashi is Jyugo's former cellmate. A box full of non-lethal weapons is open to the participants. Hajime fares well while fighting barehanded against Kenshiro, but Kenshiro fights back with an invisible attack technique by the crack of his whip. However, Hajime eventually dodges the attacks and defeats Kenshiro. Meanwhile, Jyugo does not fare well against Musashi. Jyugo retaliates in a fit of rage when Musashi mentions about the Man with the Scar. Musashi fights back with a spontaneous human combustion technique by conjuring and controlling flames. ||||

| Mitsuru interrupts the fifth event and shifts the focus to Tsukumo's backstory. Yamato brings Tsukumo to the visiting room, where Tsukumo's former manager Hanzō Hattori admits that he lied to the press about Tsukumo being reported missing. Tsukumo then reveals that he discovered that the Director lied about being his biological mother. In the past, the Director and her assistant Sukegawa found a young Tsukumo, who was abandoned by his parents in a forest village. Revealed as Hattori's mother who was a former actress, the Director pretended to be Tsukumo's mother and trained Tsukumo to become a ninja. However, the Director was just grooming Tsukumo to become a child actor. In the present, Hattori tells Tsukumo that he has the potential to play various character roles for fame and wealth. After Jyugo eavesdrops outside the visiting room, Tsukumo admits that he enjoys being an actor, but he ran away from the talent agency after realizing that he was only seen as his character roles. Although Tsukumo plans to find his village after his prison release, Jyugo encourages Tsukumo to stay true to himself. Mitsuru says that the fifth event will conclude in the next episode. ||||

| As the fifth event continues, Jyugo's shackles on his wrists have transformed into two long blades. Jyugo unleashes a powerful burst of energy at Musashi, causing massive damage to the arena and prompting a mandatory evacuation for the panicking spectators. As Musashi counters with fireballs, Momoko orders Jyugo and Musashi to be apprehended. It is revealed that Jyugo blinded Musashi in the past. Although Kenshiro, Kiji and Samon manage to subdue and capture Musashi while dodging his fireballs, Hajime is unable to thwart Jyugo. Uno, Rock and Nico jump in and try to subdue Jyugo, but he ends up breaking free from their grasp. Just as Jyugo prepares to kill Uno, Hajime intervenes and beats Jyugo to a bloody pulp before Momoko orders Hajime to stop. A few days later, Jyugo is revealed to be unconscious and in critical condition at the medical ward. Kenshiro, Kiji and Samon berate Hajime for being so violent and spoiling the post-festival feast. In his cell, Uno also criticizes Hajime for going overboard. Hajime becomes despondent upon learning from Mitsuru that Momoko has suspended Hajime for three days as punishment. ||||

| Three days later, Hajime learns from Kenshiro that Musashi, who is currently being held inside an underground cell in Building 4, will not answer any questions until he is permitted to talk to Jyugo, who is currently being held inside another underground cell in the medical ward. Hajime and Kenshiro set up an intercom via walkie-talkies. Although Jyugo is searching for the Man with the Scar in order to remove his shackles, Musashi seeks to kill the Man with the Scar, who previously disposed of Musashi after acquiring information from the inhumane experiments on his physical idiosyncrasy, his innate power to create fire. Jyugo responds despondently when Musashi reveals that his flames are now disabled. As the intercom disconnects, Hajime accuses Jyugo of having no objective and behaving like a spoiled brat. Hajime gives Jyugo five minutes to decide what he wants as the winner of the tournament. After Jyugo thinks back to when Uno, Rock and Nico discussed what they would do after they were released from prison, Jyugo begs for a second chance to be back in Building 13, having the renewed desire to pursue the Man with the Scar. ||||

| While Hajime was suspended for three days, Momoko assigns Kenshiro, Kiji and Samon to take turns covering for Hajime. On the first day, Kenshiro brings Nico to head doctor Okina Otogi for a post-tournament checkup, while Uno and Rock tag along. Uno, Rock and Nico encounter Trois and Honey, who are being treated for their injuries from competitive karuta. They all are completely enamored with nurse android KAGU-8 (Kaguya). On the second day, Kiji sympathetically gives Uno, Rock and Nico a rolled futon with a picture of Jyugo's face before teaching them about the prison layout. This escalates into an argument between Uno and Kiji over who is more attractive. On the third day, Samon prepares to wake up Uno, Rock and Nico, but they fail to avoid a session of physical training when Yamato and Tsukumo show up. In the present, Hajime says that Jyugo is being used as a guinea pig by the Man with the Scar in order to perfect the power of the shackles. Jyugo returns to Cell 13 in an apologetic mood for his reckless behavior. ||||

Jyugo, Uno and Rock visit Nico at the infirmary, where they meet head scientist Kazari Otogi, Okina's wife. After Kazari brings Nico to a newly built amusement arcade, Nico invites Upa over to the amusement arcade and eventually convinces him to play the claw crane. Kazari then gives Nico the latest video game console as his prize. Nico recalls that Jyugo helped him find his purpose in life by sparking his interest in manga. Jyugo and Musashi reconcile, while Uno invites Musashi to hang out together. Kenshiro later allows Musashi to visit Building 13 if he divulges information about his past. ||||

| In the past, Musashi was born with a rare disease that made his body temperature higher than normal. His innate power to create fire described as spontaneous human combustion eventually led to him being incarcerated in Germany after being framed as an arsonist. Unfortunately, the Man with the Scar augmented Musashi's ability rather than cured it, while the one responsible for framing Musashi was Elf, the assistant of the Man with the Scar. After gathering enough data, the Man with the Scar disposed of Musashi. In the present, Kenshiro explains that he was a former police officer, whose reports about the inhumane experiments were characterized as baseless rumors, but he still intends on exposing the truth. Meanwhile, Uno invites Jyugo, Rock, Nico, Trois, Honey, Liang, Upa, Qi and Musashi to furnish the game room as his prize. Hajime informs that all the inmates will only have one hour per day to hang out in the game room, much to their dismay.

| Elf reveals that Jyugo was set free by the Man with the Scar, now considered a traitor. After exploiting Jyugo for living freely and selfishly, Elf accuses Jyugo of running away with the shackles. As he regrets not killing Jyugo any sooner, Elf subdues Jyugo to the ground and prepares to dissect Jyugo's head with his magical knife. Jyugo manages to free himself by instinctively transforming his left wrist shackle into a long blade. Elf leaves and vows to return after revealing that he was checking up on Jyugo's current status and planning to snatch a new body. This causes Jyugo to worry that his inmates are now in danger. The following night, Jyugo, Uno, Rock and Nico attempt another prison escape, but they are caught again by Hajime waiting outside the front entrance. Jyugo locks his cellmates inside, hoping that they will be safe if he leaves by himself. A titanic fight erupts between Jyugo and Hajime, but Seitarou eventually unlocks the front entrance in order to allow Uno, Rock and Nico to intervene. Jyugo has a change of heart, deciding to stay and protect his cellmates. ||||

Jyugo and Tsukumo recover from their injuries in the infirmary, while Uno and Nico point out that Rock and Yamato have entered into a comatose state. As it is deduced that the command talismans came from Building 5, Hajime is blackmailed into allowing Jyugo, Uno and Nico to conduct an investigation at Building 5.

In the past, Qi was surprised when Upa was kidnapped for having his organs harvested as a qigong master. In the present, Hachiman still manages to move and punches Qi into a wall, but Liang and Upa kick Hachiman into another wall and knock him unconscious. While trying to reconcile with Liang and Upa, Qi recalls when he bought back Upa's organs. Nico remembers feeling at home with his cellmates. Hachiman stirs up trouble when he views Liang, Upa and Qi as weak people. Liang and Upa fend off Hachiman's attacks, and Qi releases a poisonous gas from his pipe at Hachiman.
