- Alternate Character Reading: Happened to several of the guards/supervisors not yet translated. Their kanji were on this page without any pronunciation guide, leading to names as Niemichi Teiga note , Hachimata Orochi note , Kyuubi Kitsune Inosuke note and Juhaku Tatsuzou note . The eleventh guard hasn't stated its name and is assumed to be named Rianni-Ju-Ichigo and the twelfth guard has conflicting sources on its romanization in regards to its name.
- Institutional Apparel: The four main characters wear it at least. Jyugo wears the classic striped look, while Rock and Nico wear American orange jumpsuits (Nico has a ball and chain attached).
- Manchild: Invoked by Seitarou in regards to the inmates of Cell 13 when Hajime tells him how to keep them in check. Downplayed with other inmates, who seem to be more mature than our protagonists.
- Tattooed Crook: In addition to their prison numbers, a few inmates (most noticeably Uno) have one or more tattoos.
- You Gotta Have Blue Hair: Given the manga's pretty...light tone, most of the characters have brightly coloured hair that matches it.
Height: 169 cm
Blood Type: AB
Eye color: Technicolor Eyes
Voiced by: Yuuto Uemura (JP), Daman Mills (EN)One of the inmates in Cell 13 of Nanba Prison, and the main character. He is an escape master, but knowing that hell reach nothing if he escapes, his current desire is to stay with his fellow inmates. The shackles he wears have been applied by a certain person.
- Ambiguously Bi: Jyugo claims he "likes guys too" in episode 1 when trying to think of ways to attract girls. At first we're lead to believe he's lying, but he never denies it, and at the end of the episode he's the only one of the guys still interested in being visited by Hitoshi after his true gender is revealed.
- Because You Were Nice to Me: After meeting his cellmates and becoming friends with them he noticed his dull, gray world began to have color and he started expressing more interest in "living" than simply going through the daily motions of living.
- Book Dumb: Since he's never had a formal education, he doesn't know how to read and cannot write kanji very well.
- Butt-Monkey: He's the one who gets in trouble with Hajime the most, and his inability to do anything except break out of jail is often mocked by other characters. In fact, according to Rock, he is so inept that the one time he managed to escape prison, he fell into a ditch, was forced to buy a weird pot, got mugged by a grade schooler, and was snagged by a weird palm-reader all in one sitting.
- Chained by Fashion: He has large manacles on his wrists and ankles that won't come off, and wants to find the Man with the Scar in order to find a way to get them off.
- Crippling Overspecialization: As stated above, he isn't good at anything other than jailbreaking. His cellmates even have to hold him up in the bath so he won't drown and he can't even solve basic math problems.
- Desperately Looking for a Purpose in Life: He's more troubled by the fact that he doesn't have goals or hobbies in comparison to his friends than he lets on initially.
- Does Not Like Shoes: Doesn't wear shoes for reasons unknown.
- Escape Artist: His forte. He's been trying to break out of jail for as long as he's been alive, and although the rest of the prison is known for escaping numerous times, he's the guy who does it the most.
- Heroic BSoD: First time, when he's thrown into the underground and Hajime cruelly taunts him about not having "greed" and being empty inside. Hajime did this to finally get Jyugo to admit he now had something to live for- being in Prison 13 with his friends. Second time, once Elf taunts him about having Jyugo's friends experimented on he is downright horrified and goes into a state of shock not knowing what to do.
- Kaleidoscope Eyes: As stated in the manga, his eyes change colour "at different angles", so much so that they are each differently coloured from panel to panel. In the anime and stage play, Jyugo has a simpler case of heterochromia, with one eye being purple and the other being green, but his constant color change is referenced in the first OP.
- Magnetic Hero: Cell 13 was brought together by a mutual friendship and saving by Jyugo. He's the one that helped them with their personal problems and got them to escape with him, to the point where all of them are gathered together in the highest profile prison in the world.
- Meaningful Name: Is also read as 十 (juu) and 五 (go).
- When He Smiles: While he's not a Perpetual Frowner per se, at the end of episode 12 in season 1, he smiles to himself, thinking that it is the first time that he has ever looked forward to the next day, and blushes too. And it's adorable.
Voiced by: Tetsuya Kakihara (JP), Alejandro Saab (EN)One of the inmates in Cell 13 of Nanba Prison, and one of Jyugos friends. He is a gambler and he is very perceptive as such. He also says that he has a notorious history with women, but such a thing cannot be confirmed nor disproven.
- Awesomeness by Analysis: Uno is extremely observant, and can tell what kind of person someone is just by looking at them, which is best shown when he faces Honey and Trois in the New Years' Tournament.
- Butt-Monkey: While Jyugo is the one most frequently caught by guards, Uno often falls victim to Amusing Injuries and mockery from characters who aren't in Cell 13.
- Imperturbable Englishman: Inverted. Uno is rather excitable and jumpy in the face of danger, unlike what one would believe of his compatriots.
- Jerk with a Heart of Gold: Probably the most prominent one in the series; his official profile says that he is the kindest of the Cell 13 inmates, despite how rude and violent he can be if he's annoyed. He is also the closest to Jyugo, and spends a lot of his time taking care of him.
- In an extra manga chapter, it's shown that he despised Rock and Nico upon meeting them when the four Cell 13 inmates ran into each other after they all broke out of jail. Despite the fact that he and Rock kept butting heads and how Nico unintentionally gave Uno one of his weird diseases, Uno quickly warmed up, and gave them a cheesy speech asking them to be his friends. It especially showed through with Nico, who immediately latched on to Uno after finding out that he was good at gambling and gaming; Uno ended up playing card games with Nico for half the night.
- Long-Haired Pretty Boy: The anime adaptation spares no sparkles when he undoes his long, lustrous hair.
- Meaningful Name: Doesnt use Goroawase, but he still follows the Theme Naming as Uno is Spanish for One. It's also the name of a famous card game, which may be the inspiration of his love for card games.
- Multicolored Hair: Has blond hair with hot pink shades.
- Rapunzel Hair: Wears his hair in a thick braid that reaches past his ankles; you can barely see anything other than his face when he sleeps with it down. It's even more prominent in the manga, where he pisses Rock and Jyugo off with how he constantly makes them late because of how long it takes to brush and braid it in the morning.
- Team Mom: He is shown to be very caring towards his cellmates (especially Jyugo and Nico), and this even extends to other prisoners at times. Nico lampshades it at one point, saying that "Uno's starting to sound like a mom."
- Urban Legend Love Life: He's reported to be a bit of a player before his time in Nanba, and he's greatly disturbed by the lack of women there. However, all of that was off panel, so we'll never know for sure what kind of romantic escapades he got into.
Voiced by: Ire Shiozaki (JP), Jarrod Greene (EN)
- Big Eater: Loves food and takes as much as he can any time he can get it. It's not Played for Laughs as there is a Freudian Excuse for it: every prison he was bounced into either had terrible tasting food, let him starve, or deliberately starved him. Jyugo busted him out and gave him a real meal, kickstarting his love of food.
- The Big Guy
- Byronic Hero: A good person with a dark past and a lot of angst who engages in hedonistic behavior; yep.
- Delinquent Hair: The only one of his group with it, as he rocks a multicolored mohawk for the whole series.
- Good Scars, Evil Scars: Has a scar across the bridge of his nose.
- Kindhearted Cat Lover: Has a huge soft spot for the cat that follows Hajime around, and takes it with him every time he sees it.
- Meaningful Name: Is also read as 六 (ro) and 九 (ku).
Voiced by: Daiki Kobayashi (JP), Justin Briner (EN)
One of the inmates in Cell 13 of Nanba Prison, and one of Jyugos friends. A guy who loves manga, anime and video games. He is considered an inmate with a number of incurable diseases and takes a lot of medication.
- Afraid of Needles: To the point that he broke out of his previous prisons just to avoid medical checkups. He has very good reasons for this.
- Ambiguously Brown: It's never stated what ethnicity Nico is, though he might be Black, given the many that live in America.
- Badass Adorable: Nico is the youngest and cutest of all the Cell 13 inmates, but as shown during the New Year's tournament arc, he is capable of amazing physical feats when not medicated, though it can potentially endanger his life if he pushes himself too far. He's able to instantly copy Upa's Qiyong moves, which took the other inmate years to master, upon seeing them for the first time, just because he thought that they "looked cool". He's also apparently able to perform moves from different action anime for real.
- Beware the Nice Ones: Nico's one of the nicest characters in the series, just as long as he gets his medicine. He can also effortlessly copy attacks.
- The Cutie: Nico's an extremely cheerful and adorable Otaku who has the innocence and personality of a small child. Even though the cast is largely made up of loud and impulsive jerks, most of them have a soft spot for him due to how sick and frail he is, and are willing to set their pride aside long enough to help him if he's experiencing a medical emergency. He's also the Cell 13 inmate who's the least likely to get yelled at or smacked by the guards for his foolish behavior.
- Cute Bruiser: Nico is the smallest of the convicts and has a ball and chain attached to his leg (which should slow him down in theory), but that didn't stop him from breaking walls down while escaping from prisons in the past. Apparently, if he doesn't watch himself, his actions put a strain on him.
- Green and Mean: He has green hair, but he'll only be mean if he doesn't get his medicine.
- Ill Boy: He needs to take medicine for his various conditions, but is otherwise fine. Or not. If he doesn't get his medications, then the pain will take over and bring out his murderous split-personality. That's thanks to all the torturous experiments prison doctors performed on him in the past; the poor guy doesn't even know about it's exsistance. Also, part of the reason for the constant medication is that all the experiments left him with an insane level of power and ability for impressive physical feats, but his body structure is so weak and unstable that it could kill him if he uses it.
- Meaningful Name: His name is usually rendered in katakana (ニコ) invoking 二 (ni) and 五 (ko) but can also be rendered as ニ子, literally meaning 'second child'.
- Otaku: Nico is a big fan of Japanese animation who spends most of his time watching Anime, reading Manga, and obsessing over video games (to the point that, according to Hajime, providing him with the former two will distract him from breaking out of his cell so much). Also counts as an Occidental Otaku, as Nico's American. This becomes more meaningful in season 2, where It's revealed that he was painfully abused in prison hospitals as a child, to the point that he was severely depressed and wished that he could die before he met Jyugo. The other inmate freed him from the lab he was locked in and, when they met again later on after they became cellmates, Jyugo introduced Nico to Japanese culture by giving him a manga magazine to cheer him up.
- Split Personality: If he's not taking his medicine, the pain will overwhelm poor Nico, and his more violent side pops up.
- You Gotta Have Blue Hair: His hair is naturally lime green.
- Token Good Teammate: While the Cell-13 inmates aren't technically evil, he is definitely the nicest. He doesn't have angry outbursts like the others, and Hajime even calls him a good kid and says that he is the easiest to deal with. While he does go along with his cellmate's escapades because he finds their break-out attempts fun, he's perfectly content if he has anime, manga, or a game of some sort to occupy him.

- Kindhearted Cat Lover: Has a white kitty he cares for
- Supreme Chef: His food is highly praised by the inmates, especially by Rock. Ties into National Stereotypes, as Shiro is French.

- Meaningful Name: His name contains the kanji for bunny or rabbit or hare (its all the same in Chinese) twice - 兎. As with almost all guards, his name has the Building number in it, one in his case (一). Brings to mind the name Ichiyou Higuchi, a famous female writer whose likeness adorned Japanese banknotes at some point, and is one of the three women have done so. This can reflect his superiority in his field of work.

The Supervisor of Building 2 is called Nakaido Teiga.
- Animal Motifs: A tiger. His last name sounds like 'tiger' and he definately shows sharp teeth and stripes in the image. He also wears a cape with a white tiger stripe pattern on it. Plus, it's similar to how tigers are 'big' cats and Mao is just a house cat.

- Agent Peacock: He can still kick your ass without messing up his makeup.
- Animal Motifs: A pheasant.

- Glowing Eyesof Doom: Gets these whenever someone ticks him off.

Honey voiced by: Takao Mitsutomi (JP), Kyle Igneczi (EN)Inmate number 3 and inmate number 82, usually mentioned in the same breath.
- Chivalrous Pervert: These two are together the quickest to hit on Kaguya. (although Kaguya doesn't remember meeting Honey for some reason)
- Difficult, but Awesome: Honey's weapon. They're bullet shells with a needle through it, laced with monofilament wire. The threads are so thin they barely can be seen, and Honey needs a good eye to keep track of them. The needles aren't that strong either, and one thread can't pull a person. Bycoming factor is that Honey has been making these in secret, as he steals the bullets from the shooting range. The reason why he does this? They can bring immense devastation - see Ruka. They can slice pieces of the ground, even.
- Hidden Depths: Trois is quite proficient with mechanics if given the resources. Honey has a sharp eye, and that certainly comes in handy with his strange weapon.
- Meaningful Name: 'Trois' is French for 'three' as he is French himself. The kanji used for Honey is literally 八 (ha) eight and ニ (ni) two, the ー is there to indicate that the kanji in front of it has an elongated pronunciation.

After years confined in a building, she was led outside by Enki Goku. She lived in the mountains with him and his brother for some time, until she was taken away and met her brother. Part of her memories were wiped and she was sent back into society again, who was still very afraid of her although she had learned to control her powers a bit while in the mountains. She was locked inside a cave for ten years, only surviving by drawing out the life of all the plants in the surroundings, leaving the area barren. When her brother heard of a 'monster in the mountains', he sought her out and finally freed her.
- Meaningful Name: Their names refer to Genzou Sanjou/Tan Sanzang/Tripitaka, or rather, the monk or priest that travels with the other three animals in Journey To The West. 三 is three, as you may have noticed. 法月 is law moon and 法子 is law child, they share the same character (法) with only a different pronunciation.

Building 6 of Terror
- Hidden Depths: From what we've seen, despite his overwhelming and scary appearance, he's the first to worry when the Warden announces she's going to leave Nanba for a while and he shakes when asking who is going to take care of the prison now. Later chapters reveal that his personality is a bit split; altering between a Shrinking Violet to Ax-Crazy.
- Meaningful Name: His name means 'to tame, to subdue'.

- My Hero, Zero: As the top guard of Nanba, he's appointed with the No.0 position.

- Sibling Yin-Yang: Hajime is as manly as one can get with his gruff attitude and his smooth, masculine features. His brother Hitoshi, however, is a different story.
- Team Dad: For the Building 13 boys. He looks after them like they're his problem children, and seems to be a Parental Substitute for Jyugo.
- Workaholic: Hajime lives for his work, and when he's suspended for three days on account of his thrashing of Jyugo, he becomes depressed for a while. He finds ways to work even then, doing everyone's paperwork out of boredom and contributing to building projects when he's finished with that.

- Astonishingly Appropriate Appearance: For a guy named Elf, he certainly looks the part. He shares the blonde hair, lanky appearance, and pointed ears of them, but leans more towards a malevolent member of The Fair Folk than anything.
- Dead All Along: He isn't exactly human; he's more akin to a spirit that can possess people.
- The Dragon: To the Scarred Man.
The Warden of Nanba Women's Prison is called Shin Sauzando.
- Meaningful Name: His last name is a Japanized version of 'thousand'.
- Spear Counterpart: To Momoko. He is the complete opposite of her in terms of personality, and in assignation - a male Warden in a Women's Prison. Like Momoko, his name refers to a higher number than the rest, but instead of hundred, it's thousand.
