Mikako Minamino is a photographer on Atamistar. She was a former member of AKB0048 as well as a former Center Nova who was also known as Minami Minegishi the 5th (峰岸みなみ (みねぎしみなみ)), also known as Mii-Chan (みぃちゃん).
She has long green hair and green eyes. Like all members of AKB0048, she used to have a heart-shaped lining on her hair and eyes. Now the heart-shaped lining is replaced with a diamond-shaped lining, indicating that she had graduated. She also wears a white beach hat and sunglasses to hide it from the other members of AKB0048 .
She has a tendency to say words in pig latin, like saying Thanks like Anks-Thay or Sorry like Orry-Say. She's also passionate about her work as a photographer. However, when it goes to the subject of Center Nova, Mikako becomes very serious and even tells Tsubasa that she will do everything in her power to stop the latter from activating the Center Nova position, indicating that she knows something about what really happened to those who were the Center Nova that Tsubasa clearly does not.
- Unlike the other Center Nova, she is the only one who ran away before disappearing.
- Some fans believe that Mii-chan also saw the dream that Nagisa had in episode 1.
- She denied the fact of her intentions to stop Tsubasa from activating the Center Nova position.
- From the events in episode 7, it is highly possible that she works undercover for Zodiac Corporation under Chieri's father, to know the Center Nova's phenomenon. However, it is unknown whether she knows of Chieri's father's real motives and plans. At the end of the episode, Chieri's father said that he will attack Akibastar, and it is unknown if Mikako knows of his actions. Howeverr, in episode 8, it is confirmed that she didn't know about his plans.
- Her goal on the agreement with Zodiac Corporation may involve opening the gateway and rescuing all the Center Novae.
- In episode 7, she gave birth to her own Kirara. It is also mentioned that her piloting is the best in AKB history.
- When she said she'll be "starting over as an understudy", it might be an allusion to the real Minegishi Minami who "started over as an understudy".
