This is a list of characters in the manga and anime series Mirmo!. The main ones are four human teenagers and their fairy partners (called "muglox" according to ShoPro/Viz Media materials^[1]). Each set of four has complicated relationships which are the driving force of the story. In addition, there is a large cast of supporting characters, including regular characters, some of whom change with each arc (original, Wonderful, Golden, and Enchanted seasons, as well from the Murumoya fansite; for details, see List of Mirmo! media). The fairies use musical instruments as their magical tools.

Mirumo (ミルモ) / Mirmo Voiced by: Etsuko Kozakura

A cute fairy (whose height is 10 cm) who is playful but at times selfish and lazy. He is Katie's partner and Yatch's rival, and the prince of the Fairy World and Murumo's older brother. Although he is Rima's fiancé, he refuses to marry her because he only likes her as a friend. He uses a pair of maracas as his magic tools. His favorite dessert is Chocolates and KumoCho (short for "Cloud Chocolate"). As a member of the Royal Family, he can turn humans into fairies for 24 hours. He also apparently favors butting people with his famous "Butt Fist" on weak enemies who do not require hard attacks. (First appearance: episode 1)

Rirumu (リルム) / Rima Voiced by: Mayuko Omimura

A pretty female fairy (with a height of 9.5 cm) and Dylan's partner. She loves Mirmo and wants to marry him, much to his disappointment. She is Mirmo's fiancée, and tries to get along with Mirmo on dates. At times, she may look very cute and innocent, but she can actually be quite aggressive. Rima is not exactly the champion when it comes to magic and household chores, and she even makes magical situations worse if she "helps." She cooks food for Mirmo, but instead of Mirmo eating it, he keeps avoiding her because of the food's appearance and taste (they all look weird and inedible). She uses a tambourine as her magic tool. Her favorite dessert is cream puffs. She marries Mirmo in the final chapter of the manga. (First appearance: episode 1)

Yashichi (ヤシチ) / Yatch Voiced by: Yukiji

Like his partner Azumi, Yatch is brash and impatient with his henchmen, Sazo and Hanzo. He continues to annoy Mirumo to no end due to their long-standing rivalry. But even if Yatch and Mirmo are always fighting, they help each other to save their partners and other people. He is a ninja, due to his ninja-like weapons and looks. Because of that, he is very skilled and gifted in his instrument, which you can tell during his magical dance, because he can hit his Triangle at the exact right beats with only one hand, holding the hitter and not holding the Triangle. Although unfriendly at times, he helps the others when it all depends on him. He's also fond of looking at people's underwear and drawing pictures of them (which he consider precious), much to Azumi's embarrassment. Yatch dislikes Azumi since she treats him like a slave and makes him clean the house all day, but he knows that he cannot go on without her. He is an avid fan and former executive apprentice of the Warumo Gang, and uses a triangle as his magic tool. His favorite food is karintos. (First appearance: episode 2)

Murumo (ムルモ) / Mulu Voiced by: Rie Kugimiya

An immature, cute little fairy (with a height of 8 cm) who is Mirmo's younger brother and Kyle’s partner. Mulu loves marshmallows as much as Mirmo loves chocolate, and he uses his personality to relax or manipulate others to get what he wants. At times, he is kind and sweet to his friends and is willing to help them when they are in trouble. But he can also be greedy and selfish when it comes to marshmallows, and will do anything to make Kyle give him some (even telling him about Katie and Dylan's dates). He commonly uses the phrases “deshu” or “mashu.” When he is angry, he uses the two “antenna” on his hat to create lightning and electrocute the offender. It is called "Electric Beam!" He uses a snare drum as his magic tool. (First appearance: episode 1)

Kaede Minami (南 楓, Minami Kaede) / Katie Minami Voiced by: Mai Nakahara

Age: 13-14

A cheerful and energetic girl and Mirmo's human partner. Though friendly and always willing to help those in need, she can get angry when she is tempted. Katie's main love interest is Dylan Yuki, and is the romantic rival of Azumi. Her results to grab his attention are mediocre as a result of her clumsiness. During season one of the anime, she attended the fairy school with Mirmo, but she is very different in her fairy form compared to the normal citizens of the Fairy World, with fairy wings, a pink fairy outfit, and her instrument, a microphone which was destroyed at the end of the first season while she was trying to save Fairy world. In episode 142, she almost died as a shinigami stole her soul for Mirmo's chocolates. At the season finale of Mirmo Zibang, Katie struggles to fight for Dylan's love. Unfortunately, Dylan made a decision that broke her heart, by choosing to be with Haruka Morishita. Katie decided to give up her chance of being with Dylan but not her feelings for him. Later on, when Dylan realizes that Katie is the one he really loves, he decided to confess his feelings to her.

In the final episode of the anime, Katie loses Mirmo in replacement for her wish to come true, then finds out that Mirmo never made to the Fairy World and received an extreme punishment. She then tries her best to bring back Mirmo's memories of him being a fairy, and in the end, she gets Mirumo back. In the manga, after she and Dylan become a couple, another tomboy rival named Ryo Sanada appears. (First appearance: episode 1)

Age: 13-14

A smart and quiet bookworm and an honor student, on whom Katie and Azumi have crushes, and who is Rima's partner. Although he is silent, cool, calm and reading most of the time, he's willing to help his friends, even if it embarrasses him. It is a bit mysterious who he liked first, Katie or Azumi, since he went out with Katie in the first season of the anime. He is also afraid to eat green peppers. In the near end of season four, when Haruka Morishita, his childhood friend confesses her strong love for him, he begins to gradually get close to her. When Haruka makes her decision to set Dylan free because she knew that Katie is the one he really loves, she tells Dylan that he should do something or else he will lose the person he wants. After his small argument with Rima, he goes home and he looks like he is thinking of something very deep. He then decides to call Katie and ask her to meet him at the park and asks her if she can bring a watch. At the park he tells Katie about how he feels and finally confesses to her. Gladly, Katie, of course, accepts his proposal. (First appearance: episode 1)

She can be very vain at times, but helps her friends if she decides to. She's partners (or more like partner-in-crimes) with Yatch since Azumi wants Dylan and hates Katie, just how Yatch hates Mirmo. But most of the time, she leaves Yashichi to do her household chores and treats him like a slave, but seems to have a soft spot for him. She also has a younger brother named Mizuki but is rarely seen. At the near end of anime season four, Azumi challenged Katie to know who really is the right one for Dylan. Katie wins at the end of the battle. Azumi accepted her loss but warned Katie and said that "if she starts doing the wrong thing again, she will never let Katie take that chance again." In the manga, after she broke up with Dylan, she went dating with Sumita and Hirai but failed, and she is the idol of Sazo and Hanzo. (First appearance: episode 1)

He has his own butler/security guard/caretaker, and relies heavily on him. Although he may not show it, he is a cry baby and spoiled, once when he fell on his rear end, he had an entire set of medical machines and when everyone left, he started bawling, but he can hide it just as fast, like when Katie enters the room. But he is still spoiled, as showed when he met Katie and his heart beat increased, his butler then considered bringing in an entire team of doctors. In the season finale, Kyle managed to propose to Katie, but Katie turned him down, causing him to act and look like an old man (his way of showing his heartbroken self).

When the message finishes, he looks at Etsumi and shows her the pendant (They look at each other).
