Introduced as a point-of-view character in the novel, she has her own side story chronicled during the events of the High Priest's rampage in Academy City as she tries to deliver the liquid diamond that her parents worked hard on while being chased by Kenzan Shouji and his friends wanting it for themselves. In her adventure, she would cross paths with several other established characters in the series.
Akikawa Mie has shoulder-length black hair and a healthy tan. She wears a white long-sleeved sailor uniform, a shorter-than-average miniskirt and a mint green cardigan, tied around her waist by the sleeves.
Mie acts as a stereotypical teenager, having conflcting feelings like wanting to assert herself via her appearance but not wanting anyone to notice and point it out to her, as well as being embarassed of her own father. Regardless of this she loves her parents and the work that they do even if she doesn't understand it herself. And from that stems a stubborn determination that led to her smuggling liquid diamond for the sake of her mother's work despite her own mother's objections.

Akikawa Mie is in one of the buildings that High Priest threw at Misaka Mikoto, who was able to save it and its occupants using her electromagnetic powers. She was there because she wanted to skip the Anti-Crime Orientation, but was later tasked by her mother to go to the aforementioned building so that she may bring her father his lunch. She later finds herself and the entire building upside down, though she is unscathed thanks to Mikoto's efforts.
Traversing the upside down building she comes upon her father apologizing to his boss about what had happened despite being beyond his control, much to her chagrin. She later tries to leave the building while talking to her mother on the phone. Here her mother talks about the qualities of Mie's father to her as well as the vaults that her father builds for her liquid diamond. After hanging up with her mother she comes upon one of the vaults that his father built that has been crushed after High Priest's rampage. Already worried about the liquid diamond that both her mother and father had worked on, her fears becomes exacerbated once she relies someone is out to steal them. They are Kenzan Shouji and his friends. She quickly takes the storage tube of the liquid diamond and makes a run for it, alerting her presence to Shouji and the others. Thus her journey to take the liquid diamond to her mother begins with Shouji and his friends on her tail believing she is also out to steal it.
As she continues trying to get to her mother, she has a conversation with her over the phone. Her phone tells her to abandon the liquid diamond because it was too dangerous for her and that her company could easily track it down, but Mie is adamant about her decision, surprising her mother. After hanging up she comes into a subway station, bumping into several familiar characters, paranoid of everyone's intentions. When she notices that a girl is sensing that there is something valuable nearby, Mie concludes that she must be referring to the container of the liquid diamond transmitting something. She desperately tries to scrape the writing on the container, in the baseless hope that she won't get tracked down.
Still paranoid, when the train stopped because of High Priest's attacks in one of School District 5's transformer substations, Mie bumps into Hattori Hanzou and Kuruwa. She later flees the train despite the power still not being up, bumping into Shirai Kuroko along the way. Her running doesn't get her far however as her worst fears come to fruition. Kenzan Shouji and his friends later catch up to her, forcing her to give the liquid diamond. Unfortunately for them Kamijou Touma was nearby, and seeing her plight, decides to save her despite being chased by the High Priest. Touma plows the Acrobike into Shouji, allowing Mie to take back the Liquid Diamond container. Touma tells Mie to hold on to the container and get down as he pedals away. Immediately afterwards the High Priest passes through, still trying to catch up to Touma. This allows Mie to escape with the Liquid Diamond, thinking that the High Priest was her savor.
When she arrives at her mother's company, she is met by her mother, embracing her and telling that everything is going to be all right. Here, she witnesses first hand the teamwork and unity of the citizens of Academy City to avert disaster, including her own father. A fact that Kamijou Touma believed and relied on in order to avert the disaster that would happen when the High Priest decided to take the dirt from under Academy City. This however was under the manipulations of Kihara Noukan, making calculations and sending out bait like the liquid diamond that Mie took to prevent human casualties during the High Priest's rampage.
Despite the city being saved from collapsing, Mie herself was not saved from danger. All of a sudden, Kenzan Shouji arrives and points a gun at her, demanding her to give him the Liquid Diamond. With his finger on the trigger, Higata Akio, one of his accomplices, finally had enough of him and hits him with a metal pipe. This distracts Shouji long enough for Mie's father and Shiosai, the man whose gun they stole, to knock him out. Shiosai then cuffs him. Mie asks Akio why he attacked Shouji afterwards, to which Akio says that it was a better alternative than him becoming a murderer.
