Rio: Rainbow Gate!

Rio: Rainbow Gate! is a Japanese anime television series animated by Xebec. Based on Tecmo's Rio Series series of pachinko games (from Rakushou! Pachi-Slot Sengen), the series revolves around titular character Rio Rollins, a popular casino dealer working at the Howard Resort who is known as the "Goddess of Victory", and the thirteen cards called Gates which are used to determine the world's most skilled dealer. The anime aired on Tokyo MX and related channels between January and March 2011.

Plot
In an island casino called the Howard Resort (ハワードリゾート), Rio Rollins is a popular casino dealer with the ability to bring good luck to gamblers just by walking past them, earning her the nickname "The Goddess of Victory". Mint Clark, a young child, comes to the Howard Resort with her grandfather and encounters Rio, and the two become the best of friends.

Rio's life soon changes when it is revealed that she is a "Gate Holder", a dealer who holds one of the 13 legendary cards called "Gates", and whoever collects them all will be named "Most Valuable Casino Dealer" (MVCD). To collect all 13 Gates, Rio must take part in special matches called "Gate Battles" with other Gate Holders and gain their Gates to become the most valuable casino dealer in the world.

Main characters

 * Rio Rollins Tachibana (リオ・ロリンズ・タチバナ)
 * The most popular dealer in the Howard Resort casino who abides by the motto, "As the customer wishes" (お客様がお望みなら). Beautiful and well-endowed, she has a mysterious energy that gives good luck to her customers, earning her reputation as "The Goddess of Victory" (勝利の女神). Rio is the daughter of the legendary dealer Risa Rollins, and has inherited her dealing skills. She has a pet ferret named Chip, and is revealed to be afraid of lightning, as shown during her stay at Misery's castle. It is revealed during one of her Gate Battles that she is a "Roll Ruler", an individual who can change the outcome of a Gate Battle through the aid of illusions. Rio was given the #7 Gate by a mysterious man, and currently holds six Gates after her Gate Battle with King, though it was later revealed that most of the Gates she won were Rina's. She later gains the #8 Gate from Dana, the #2 Gate from Joker, and the #10 Gate from Yang-Yang following her loss to Rina at the Sky Resort. She finally beats Rina in the final battle, claiming all 13 Gates and gaining access to the Ultimate Roll Ruler and the title of MVCD, which is the title bestowed upon the greatest dealer.

 * Rina Goltschmidt Tachibana (リナ・ゴルトシュミット・タチバナ)
 * Rio's childhood friend who had been recruited by Tom Howard as a dealer. Her mother was hospitalized and her father was frequently away on business trips when she was a child, and therefore was raised by Risa, during which she had a sibling-like relationship with Risa's daughter, Rio. She has a mysterious energy that makes her customers weary, as opposed to Rio's aura which gives her customers energy. It is later revealed that she is Rio's half-sister and a Gate Holder working under Cartia, who is revealed to be her aunt. She seeks revenge on Rio and her mother, Risa Rollins, who allegedly eloped with her father, causing Rina's mother, Ilina, to fall into a coma. She is also revealed to be a Roll Ruler, with her abilities far surpassing Rio's, but lost to Rio at the end of the series. Before the final battle, she held nine Gates, four of which were given to Linda, Jack, Queen, and King, and one of the Gates being the Ace Gate.

Howard Resort staff members

 * Linda (リンダ（LINDA-R-2007）)
 * A cheerful robot who is the head dealer of the newly built Sky Resort, sporting noticeable tan lines.

She was briefly reprogrammed by Jack to challenge Rio to a Gate Battle, carrying the #4 Gate hidden in her left wrist (which was given to her by Cartia, later revealed to be one of Rina's Gates), but lost after her head came loose just before crossing the finish line. A running gag in the series is that her head often falls off her body when least expected, often causing glitches in the computer system.

Howard reveals to Cartia that the Concentration Bomber was an unstable project, which is why he had it shut down. An-An manages to save Mint when the card underneath her exploded, where it is revealed that she is actually Choco brought to life by Yang-Yang's magic, as she wanted a companion (she claims her magic only works on items made in China). Choco turns into An-An once again during a bonus episode, where she repays Mint's kindness by buying her a camera.

 * Misery (ミザリィ)
 * A woman who once owned a castle with a casino inside of it. However, she lost everything after losing to a high-stakes game of craps.

She also has a bottomless appetite for chicken wings, as they were once her favorite, shown when she downs multiple boxes of them. She attacked Elle and Ille, both of whom she later possessed, and took over Rosa's body after she possessed her. She then challenged Rio to a game over the resort, and initially had the upper hand tricking Rio with her illusions, but they were dispelled after she ate a super-spicy chicken wing from Rina who disguised herself as a delivery girl, allowing Rio to win the game and her friends. It is later revealed throughout the series that Misery is still residing in Rosa's body, as she possessed the latter to tell Rio that Jack had aided her in her games against Orlin and Elvis and warned her about Cartia's intent to tear down her castle before she releases control.

He soon lost to Rio after the third stage of the match, but later teams up with her to save Mint from the fourth stage after Linda's head was accidentally knocked off by Carlos.
