Mimi Atachi

Mimi is 37 years old petite lolita with shoulder-length carrot hair and large sparkling violet eyes. She wears a light pink skirt that goes down 'till her knees coupled with white socks with pink ribbons attached to its top corner side, and low heel flat red Mary Jane shoes.

She wears different outfits throughout the series. For example, she dresses in a tight red dress and black heels that show the latter's bearing. To top it off, she has on a sign saying "I am an adult" – to deter others from assuming her as underage. Being a member of top executives in Goha, Mimi sports a Goha's Hexagon uniform. The uniform contains a light-gray short skirt with a pocket on its left bottom-side and top-right corner the Goha Corp logo with leggings and shoes of the same coloration. She also wore a helmet with the Goha Corp logo tatted on it, light gray gloves, and a gray cape to topple it.

She has also donned a dark gray jumpsuit with a pink skirt armor on top, a heart-shaped helmet to cover her face, and light pink gloves. She also has on a short orangish scarf tied into a cross.

Mimi is rather kind and sympathetic which can be seen she saw Yuga has no malice. When people get her confused for a child due to her appearance, it drives her to work hard and rise to top of Goha Corp. Mimi always shows her caring for those close to her which was clear seen toward her son.

During the top brass meeting in Goha Corp, Mimi brought up the Rush Dueling getting out of control and can't find the data program. Many executives brought up the idea that they might get information on this Rush Duel from Goha 7th Elementary presenting a copy of Goha 7th Newspaper. President Goha points at the paper's photo of Yuga Ohdo that showed him claiming his notebook contains all the secrets of Rush Dueling. Mimi was chosen as a candidate to go undercover to retrieve it. Mimi was transferred to the school the next day to obtain a notebook from Yuga Ohdo. She approached Yuga by appealing to him, sowing the interest in this Rush Dueling from Goha 7th Newspaper to the point of even asking Yuga to teach her about it. Yuga was more than friendly to help Mimi even though Luke, Romin Kirishima, and Gakuto Sougetsu were suspicious. Mimi gifted Yuga and his friends a cash load to relieve their worries, which Yuga straightforwardly reclined. Yuga brought her to his Road Laboratory and even showing her the ruled notebook of Rush Duel, piquing Mimi's interest and acting weirder. She soon left after taking a call saying she has some business to handle. Romin seeing these points that Mimi might steal his notebook. Yuga disagrees with this claim, but Mimi came back to the lab to steal the notebook. Caught in the act, Mimi brought up the excuses she wanted the notebook to learn more about Rush Duel. Yuga offered her to take it, but she declined it – so they decided to settle it with a Duel. Yuga claimed victories allowing Mimi to borrow his notebook.[1]
