DICE: The Cube That Changes Everything Wiki

Mio is one of Dongtae's classmates that became a Dicer in the chaos of Byungchul's death.


Mio's Change

Prior to becoming a Dicer, Mio was very obese, had pimples, and wore glasses. Her hair was dark brown, relatively in a bob-cut style haircut and she had a huge piggish nose. Because of this, her classmates often called her P.G.P, meaning The Pig with Glasses and Pimples. In Korean the combined terms were 'Ahn Yeohwe'.[2] She was also called an "Orc Scholar".

After Byungchul's incident and death, Mio took one of the dice, and which made her a Dicer. She is one of only few embodied dicers who changed their overall appearance beyond recognition, like Taebin's transformation. Currently, she has a slim, elegant body, flawlessly smooth skin with hot pink-colored bob cut hair, and big, clear green eyes. She has slightly cat-like in appearance, as described by a guy trying to hit on her.

Dicership gave Mio confidence to pursue her goals the same way as Dongtae, but she is much more straightforward than he is, being unafraid to speak her mind quite often, especially towards Dongtae. She will even criticize what she thinks is wrong in one's reasoning, and heavily tends to scold Eunjoo for her on reasoning at times.

Although she is a kind, good-hearted girl, she still remains somewhat insecure due to her past self, and often masks that with displays of aggression. As a result, she reacts quite angrily at times when reminded of her former physical appearance, even in the form of a compliment, most notably coming from Eunjoo.

Morally, Mio is similar to Dongtae: she believes Dice are valid ways for people like them to improve themselves and pursue happiness, and has not yet been seen pursuing quests that are detrimental to other people, although what she actually did to obtain so many Dice as to change herself completely has not been shown either.

Currently, Mio is considered to be one of Dongtae's closest allies. She proves herself to be quite loyal to him in the War between the 16 A-Rankers when she chooses to be his only teammate despite his objections due to her safety. She is one of the few Dicers that Dongtae trusts completely, and as a result, he is quite protective of her, warning her to be careful when outdoors, and acknowledging that she will likely be targeted for her useful ability to read her enemies.


She first appears when Dongtae, while fuming with jealousy and running away from where Taebin and Eunjoo are, bumps into her when he turns a corner. Later, she is seen looking on when Byungchul almost kills one of his bullies with strength acquired as a Dicer.

She then vanishes from the story but reappears during the Pandora arc, when students are running amok in search for Dice. She was shown as a mysterious faceless girl who is seen collecting information on Eunjoo and is implied to be giving off Dice to people.

When X starts the mass quest against Eunjoo, Mio does not take sides until late, when she abandons a spectator position and kicks Mr No-eyes down a staircase, apparently having decided to lend a hand to Dongtae and Taebin to protect Eunjoo. Still, she only enters the fray and shows her face when Dongtae decides to create a guild to contain Dicer misbehavior. She then invites Dongtae unceremoniously to spend the weekend with her.

Later, she is passing by while Eunjoo is being harassed by Dicer girls. Initially conflicted about it, Mio ends up saving her, and in the following exchange with Eunjoo, she obtains confirmation that the girl is not interested in Dongtae as anything other than a friend, and tells her in return what his real reason for creating the guild are.

That same afternoon, she makes another move on Dongtae and invites him to share her umbrella in the walk home, going to the point of offering to accompany him to his home and cooking dinner for the two. She eventually tells him that she considers the guild a Utopia. Mio then receives a Golden Die quest from X asking her to "spend a good amount of time with Dongtae in his house". Before she has time to pursue that quest, though, X starts a new mass quest in which all B rankers are pit against each other in a fight. Contrarily to Dongtae and Taebin, she receives the quest, but lags behind to discuss Dice-related matters with the other two. When Dongtae rushes to rescue Eunjoo, she is again left behind to ponder the futility of her efforts.

Mio runs away and starts her own "guild" of a bunch of dicers she found that respect her and are loyal to her. Despite the fact that Dongtae hurt her feelings, she still tries to protect him. She even creates a battle tournament to distract the dicers, to save Dongtae. Her plan is revealed and other dicers turn on her. Mooyoung found her in all the chaos and killed her. Dongtae rewound time to save. After several tries, Mio finally survives but is left without dice. She loses her Clairvoyance die to Mooyoung.

Later on, she is turned into dice by failing to meet X's D-Day cutline. It is unknown if she can be revived but X has stated that being turned into dice is different from being killed since the person is technically still alive as dice.

Powers and Abilities[]

As a Dicer, Mio has combined her cleverness as a diligent student with great agility, and excels at extracting information from people, as well as using her kicks on the right time. She dissuades three bigger girls wielding a razor blade from attacking Eunjoo.

Her A-rank ability is Clairvoyance or True Sight. She can see the character traits of the people around her via flat, pop-up "character description" panels listing their certain attributes such as name, age, height, weight, sex, and even their A-rank ability if they have one. By spending her dice points, she can discover and "see" even more about a person, such as what they looked like prior to becoming a Dicer. Her ability has been described like being in a library where she can read the "titles" of everyone she sees, but needs to use up dice in order to "read" them like books. She can use her Clairvoyance to change "the settings" of other dicers. For example: she can change the strength setting on dicers to the point where they don't have the strength to walk. This is extremely useful except it costs a lot of dice.

However, at the same time, it is not known how capable she is of fighting against other powerful, experienced A-rankers like Mooyoung and Taebin. Because of this, her principal ally in the A-ranker war, Dongtae, considers her to be easily targeted, and feels protective of her as a result.



No nonsense.

Dongtae: Mio has quite the crush on him. She admires his upright behavior even while considering his notion of a guild utopian. If anything, she is more than a little pushy and not only sounds him out quite openly about his feelings for Eunjoo, in order to confirm that he is trying to leave them in the past, but she also offers to accompany him home and cook dinner for the two, apparently indifferent to his embarrassment and in full knowledge that she will be alone with him in his house.

Her growing perception of Dongtae's feelings for Eunjoo does not stop her from pursuing him, although it has been wearing down on her. After acquiring her Clairvoyance A-Rank ability, although she wants to hear Dongtae's voice, she avoids seeing him in fear of his "character description" stating he may not have feelings for at all. During Dongtae's visit to her place, after coming all that way, she is able to muster the courage to view his "character description". Although it states he still "likes Eunjoo quite a bit", it also reveals he "likes Mio too". As a result, she feels relieved, but at the same time somewhat apprehensive, and playfully beats on him. During their date in the amusement park, Dongtae admits having feelings for Mio and they have established their relationship as boyfriend and girlfriend since. In episode 259, Dongtae kisses Mio on the cheek in her pre-dice form.

Eunjoo: Mio's feelings regarding Eunjoo are mixed. Like Dongtae, she has memories of being always treated with unprejudiced kindness and respect by her classmate, but she is annoyed at feeling indebted to Eunjoo. Mio also seems to understand, unlike most other students, that Eunjoo's reasons for not using Dice have nothing to do with a feeling of superiority or hypocrisy, even though she says she cannot understand what those reasons could possibly be. Mio also snaps back forcefully whenever Eunjoo compliments before becoming a Dicer due to her insecurities and feeling that Eunjoo's upbringing provides her with a lack of truly empathizing.

She does recognize somewhat grudgingly that Eunjoo is the only person who did not make much of her extreme change in appearance. Although Mio may be jealous of Eunjoo due to the love Dongtae has for her, Mio still puts this aside in order to help Eunjoo in times of trouble, mostly out of her own feelings towards Dongtae. She is even honest enough to disabuse the notion that Dongtae saved Eunjoo in order to fulfill a quest and even revealed to her the prime reason of starting the guild was to protect Eunjoo.

Jieun: Originally felt suspicion and apathy when encountering her during the Mob Arc, Battle Tournament. As the battle progressed further, and her team dissassembled, she finds herself running not when encountering Jieun again, with her helping her wound.  Mio finds Jieun trustworthy enough to follow along her plan, and that ends their interaction for a while.

During the BattleRoyale Arc, she encounters Jieun again, under temporary appearance due to her lack of dice. Mio's suspicion arises yet again as she complexes between Dongtae and what Jieun has done under the temporary appearance.


  • Taebin and Mio are both Black Bishops in X's Chess.
  • Her name in Japanese means “beautiful cherry blossom” perhaps coming from her pink hair.
