Dian Keto, originally known as Dain Keto the Cure Master, has undergone a fascinating evolution within the Yu-Gi-Oh! universe. From a simple healing card to a multifaceted character with various retrains and roles, Dian Keto's journey reflects the changing dynamics of the game and its spin-offs. This article delves into the history, adaptations, and significance of Dian Keto, exploring her impact across different Yu-Gi-Oh! formats.
The Origins: Dain Keto the Cure Master
Dain Keto the Cure Master, one of the first healing cards released in the TCG, quickly became a staple for many players. The card's appeal lay in its straightforward effect: restoring a player's Life Points (LP). The widespread availability of Dain Keto made her a common sight in early Yu-Gi-Oh! decks.
While LP preservation was the primary focus for novice players, strategic thinking evolved over time. The realization that "the only LP that matters is the last one" diminished Dain Keto's competitive edge in the standard TCG/OCG.
Interestingly, despite the card's name being derived from the male Irish God of Healing, the original artwork depicted Dain Keto as an old woman which was later confirmed.
Dain Keto's presence in the Yu-Gi-Oh! lore remained minimal. The card "Healing Wind," an anime-only spell from Yu-Gi-Oh! 5D's, offered a similar healing effect (200 LP per monster on the field) but failed to achieve the same recognition as Dain Keto.

Dian Keto's Rebirth in Rush Duel
Rush Duel, a simplified and fast-paced Yu-Gi-Oh! format, breathed new life into Dian Keto. Reimagined as a LIGHT Aqua monster, Dian Keto gained new abilities and strategic relevance.
Dian Keto the Boogie Master
In Yu-Gi-Oh! SEVENS, Mimi Imimi wields "Dian Keto the Boogie Master" as her ace monster. When Mimi Summons "Dian Keto the Boogie Master", she chants, "This party is about to go crazy!". This version allows players to heal 1000 LP each turn by discarding a card. With a respectable 2500 ATK, the Boogie Master holds her own on the field. In the Duel Links meta, the Boogie Master is a solid body and a way to stall.
Dian Keto the Security Master
Mimi later takes on the role of "Dian Keto the Security Master" (Prison God in Japan). When Mimi Summons "Dian Keto the Security Master" she chants, "The party doesn't stop 'til the sun comes up! But when night turns to day, make way for the authority!" As the Security Master, Dian Keto can discard a card from the opponent's hand, granting the player 1000 LP if the discarded card is Level 7 or higher. When Mimi activates "Dian Keto the Security Master's" effect, she announces, "Incarceration!".
Dian Keto the Cooking Master
"Dian Keto the Cooking Master" (Kitchen God) offers a different utility: milling three cards from the player's deck to the GY. This effect synergizes well with Rush Duel decks that rely on GY recursion. If the player's LP are 2000 or less, discarding Aqua monsters through this effect grants an additional 1000 LP per card.
The Atachi Family and the Bubble Era
The Yu-Gi-Oh! Go Rush series introduced Manya Atachi, an ancestor of Mimi Imimi. When undercover at school, Mimi projects a more cutesy manner to act more like a child. She claims to be interested in Rush Dueling, and disguises her true intentions behind this claimed interest. Despite this, she is a genuine fan of RoaRomin, waving in appreciation at Roa Kassidy and taking the opportunity to take a selfie with him when she confronts him over his claim of Yuga's "Sevens Road Magician" card being illegal. Despite her youthful appearance and mannerisms at times and her position in the high-tech Goha Enterprises, Mimi herself is very old-fashioned; she still fondly reminisces the time of the Bubble Era as reflected in her Deck and she carries an old corded phone as part of her disguised school bag rather than a more modern smartphone, though it does contain some modern functions. The Bubble Actress archetype, used by Manya, features child actresses based on classic Yu-Gi-Oh! monsters. This connection suggests that Go Rush is a prequel to Sevens, establishing the lineage of Dian Keto's users.

Further Retrains: The Maiden Series
Several anime-only retrains of Dian Keto exist within the Rush Duel format:
- Dian Keto the Cure Maiden: Draws a card if the player controls a Field Spell, gaining 1000 LP if the drawn card is also a Field Spell.
- Dian Keto the Gourmet Maiden: Requires a face-up Spell Card to activate its effect, granting 1000 LP and increasing its ATK by 300 for each face-up Spell.
- Dian Keto the Cleaning Maiden: Requires the player to have lower LP than their opponent, granting 1000 LP and 1000 ATK for the turn.
Praime Dian Keto
In Yu-Gi-Oh! Go Rush, the Praime archetype features LIGHT variants of the heroes' monsters. Praime Dian Keto can be Tribute Summoned with only one Tribute, but with a reduced base ATK of 1000. Its effect allows it to discard a card to gain 1000 ATK and 1000 LP and add a "Praime Call" card from the GY to the hand.
Mimi Imimi: The Embodiment of Dian Keto
Mimi Imimi, also known as Mimi Atachi in the Japanese version, is a central character in Yu-Gi-Oh! SEVENS. She embodies the spirit of Dian Keto through her use of the Boogie Master and Security Master versions. Mimi is Number 6 among the "Top of the Hexagon", the six executives of the Goha Enterprises, and she is sent to Goha #7 Elementary undercover as a transfer student to investigate Rush Dueling. Mimi is demoted for her failure to keep her fellow Tops in check when they attempted to fire Nail Saionji. However, she discovers the Goha President after he collapses and becomes the new President after being chosen by the President Drone. A character resembling Mimi, Immi Imimi, appears in Yu-Gi-Oh!. Mimi is thirty-seven years old, but she has the appearance of a preteen, referring to herself as the "eternal elementary school student". At the Goha Enterprises, Mimi dresses in the identity-concealing garb that all Goha employees wear; a helmet emblazoned with the Goha Enterprises logo that completely covers her face save her mouth, a white mini-dress lined with black and emblazoned over her heart with the Goha Enterprises logo over light grey clothing, white gloves with black cuffs, and a darker grey cape. Mimi wears stereotypical girls' clothing when she enters Goha #7 Elementary as a transfer student; a pale pink dress reaching to mid-thigh with a flared skirt, white lace at the neck and cuffs, buttons down the front, and a red bow tied at the back of her waist, in addition to white knee-length socks tied with pink ribbons, and red Mary Jane shoes. She wears a charcoal variant of this dress outside school and dons small glasses and binds her sleeves while working at Goha Library. Outside of work and school, Mimi wears more normal clothes. When she visits a bar she wears a red dress and black heels, wearing a sign around her neck that states "I am an adult". At home, she wears a pink sweater and tan pants, and a white apron and scarf tied over her hair when cooking. When she takes on the identity of "Mysterious M" (Advisor M in the Japanese version) Mimi conceals her identity behind a pale pink helmet with a heart-shaped faceplate with a dark red visor and a white frame. The helmet has a smaller white heart with a tan border nestled in the cleft of her faceplate over a darker pink stripe. She also wears a charcoal jumpsuit, a dark yellow scarf, a pale pink top white a white central stripe, collar and shoulder-pads, a darker pink skirt with pale pink side seconds, and pale pink boots and gloves with white cuffs. As The☆Masked Advisor M, Mimi wears a red leotard with black peaked shoulders and hips, a black neck portion separated from the red by a white "M" shape, a black belt with a yellow "M" as the buckle and a yellow bandanna tied around her neck, all over a white jumpsuit, elbow-length black gloves, calf-length black boosts, and a white eye mask with blue bug-like lenses. After she becomes the new Goha President, Mimi conceals her identity beneath the President Drone; a helmet with a design reminiscent of a samurai helmet, with the Goha Enterprises logo emblazoned on the helmet's forehead and mouthpiece, hexagonal red eyepieces that turn blue when she is in complete vocal control, and silver horns in half-hexagonal shapes, a black mantle with a red stripe across the chest, and black clothing and white gloves underneath it. Mimi is dedicated to the ideals of Goha Enterprises, and any ideas against their control she immediately dismisses. She is hard-working as a result of the dismissal she is often subjected to due to her youthful appearance and eager to rise higher in Goha Enterprises, to the point that she can prioritize that desire over her objectives. Mimi also demonstrates little patience for Yosh's interest in Rush Duels initially and threatens to stop making his favorite napolitan spaghetti if he brings up the topic again. She was reportedly horrified when Yosh began dressing and acting like Good Max, believing that Rush Dueling had turned him into a delinquent. Mimi is so dedicated to these ideals that she assumes Yuga Ohdo must be a villain before she meets him and his genuine passion and innocence catch her off-guard to the point that she initially refuses Yuga's offer to lend her his notebook despite it being her objective, as she assumed he was tricking her. Though she can be somewhat strict, Mimi ultimately has the best interests of those she cares about at heart. She allows Yosh to Rush Duel despite her misgivings against it once she sees how he enjoys it, and when she sees Luke hesitate to help Romin Kassidy she encourages him to do so, as Romin is his friend, despite her actions. As the Goha President she is happy to accept the idea of the Goha Rush Duel Team Battle Royal, though concerned by the nature of the anonymous note sent to her. Her dual role as a Goha executive and a seemingly innocent transfer student adds depth to her character.
Mimi's Duels and Strategies
Mimi's duels often showcase her strategic thinking and adaptability. During her Duel against Roa Kassidy in "The Battle Royal Begins!", she employs a prison-themed strategy using cards like "Prison Island - Cell Block 5 & 6" and "Mystery Handcuffs" to disrupt Roa's plays.
Rush Duel in Duel Links
The introduction of Rush Duel to Yu-Gi-Oh! Duel Links on September 28th marked a significant expansion for the game. The update included a new world based on Yu-Gi-Oh! SEVENS, offering a simpler and more streamlined playstyle.
