Uno (ウノ Uno), inmate number eleven, is one of the main protagonists of the Nanbaka anime and web manga series. He is an inmate of Nanba Prison where he is held in building thirteen, cell thirteen. A compulsive and talented gambler, he was arrested for frequenting underground casinos.[5]


Uno is a self-proclaimed “good looking” young man of above-average height. He is rather well-built and has ankle-length, blond hair with deep pink streaks, worn in in a thick braid with short, messy bangs framing his face. He has fair skin and blue eyes with long eyelashes and thick eyebrows. He wears blue stud piercings on his ears and naval[6] and sports dark blue tattoos on his back and left arm; the number 1 is tattooed in dark blue on the back of each of his hands, forming his ID number 11. His nails are blue.

Uno wears a blue-and-white striped inmates' jumpsuit worn with the top entirely undone and the arms tied around his waist, exposing a black vest top. He wears a blue-and-white striped arm warmer on his right arm and a matching cap decorated with gold pins forming his ID number, eleven. Around his neck is a silver dog tag necklace. He wears black boots, and his ID badge is pinned to the left side of his chest.

Uno takes a great amount of pride in his appearance and is very confident in his abilities, often exerting a certain amount of vanity; he considers himself to be highly attractive and popular. This is exemplified by the fact that he puts a considerable amount of time into getting ready each morning as, as well as arrogantly “predicting” which of his inmates will be popular. He can be quite blunt and tactless in nature. Despite his superficial attitude, he is by no means selfish and is portrayed as a kind, warm, friendly and extroverted individual who cares greatly for his friends. He understands them well and is willing to accept them for who they are no matter what, as shown when he voiced his fondness and approval for Jyugo despite having pointed out all of his flaws moments beforehand. He’s a thoughtful person who is willing to give his friends advice, though he puts no pressure on them to tell him what’s on their mind.

Uno is described as a rather cowardly person who is easily scared. For example, while exploring the Gogyousan Underground prison he becomes terrified of the Jiang Shi dolls used to patrol the area, such that his friends initially wouldn't tell him they were there lest he became too scared to come with them.[7] Despite this, he has little problem standing up to danger, as well as challenging figures of authority,[8] for the sake of his friends.

Uno is a compulsive gambler and, because of his gambling experience, has developed not only a habit of cheating shamelessly but a high level of intuition. He is able to pick up on the habits and body language of others and uses this information to see through their movements and actions; these skills make it easy for him to win various types of fights, causing him to become rather arrogant. He views gambling as a hobby and greatly enjoys playing games with others, indicating his extroverted nature.[9]



Uno was born and raised in the United Kingdom where he frequented an underground casino. Eventually caught and arrested, he would break out by picking the locks anytime he had a date, often making plans for further dates while on the run.[10] At an unknown point of time, he met Jyguo and the two made a habit of breaking out together, ending up in the same prison several times.[11] He also met Rock and Nico while escaping in Las Vegas.[12]

Eventually, Uno’s constant escapes and arrests lead him to be transferred to Nanba Prison where he allegedly lost motivation to escape due to having no dates.[13]
