Gojo's Past Arc
Mimiko along with Nanako were captured, beaten, and imprisoned by some villagers because they believed that they were the cause of all the deaths in the village. When Geto was sent to the village, the villagers want him to kill the two but instead he kills all the villagers and takes the two with him. Later Mimiko watches with Nanako as Geto takes over the Star Religious Group.

Cursed Child Arc
One day, Mimiko along with the other leaders are summon to a meet with Geto about creating a paradise for sorcerers. After the meeting, Geto brings all the leaders to the Tokyo college so he can meet with Yuta. After Geto declares his war, Mimiko and the others leave to a specific shop to eat some crepes, since Mimiko and Nanako would only come if they went there next.

On December 24, Mimiko is waiting inside of one of Geto's spirits along with Nanako until it all starts. When the operation starts, Mimiko and Nanako exit the spirit and start to attack the sorcerers. Mimiko and Nanako encounter Kiyotaka, who tries to get them to stop all of this, but the two tell him just how hard their lives were until they were saved by Geto. When they suddenly hear a crash, they notice that Miguel is fighting Gojo. They then witness Gojo's power and are shocked by it. After a certain time is reached, Mimiko and Nanako retreat along with the others.

After Geto's death and the impostor takes over his body, Mimiko sided with Nanako with getting Geto's body back from the impostor. As a fight is about to start, Larue stops them and convinces them to go their separate way in order to fulfill their goals. Larue also tells them that their will be a day when they come back together since they are a family.

Shibuya Incident Arc
When Gojo is sealed and the cursed spirits leave, Mimiko and Nanako confronts the person who's inhabiting Geto's body and ask for him to give it back. When the impostor tells them that he won't, the two tells him that he will regret that decision.

Later, Mimiko along with Nanako find a wounded Yuji. The two start to feed Yuji Sukuna's fingers when Jogo suddenly arrives. As the two don't tell Jogo anything, Jogo takes care of them. Nanako manages to heal them both, which Jogo notices and prepares to fight them. As Sukuna awakens, Nanako and Mimoko quickly bow their heads to the ground to save themselves.
