Large-Scale Invasion Arc
Mira was first introduced together with the rest of Hyrein's crew. After Hyrein starts discussing about "Meeden", saying they hadn't yet shown their full strength. As Enedora and Hyuse threaten to fight, Mira stays quiet. When Enedora and Ranbanein ask to be sent to the battlefield, Hyrein states they soon will, and talks to her, she then confirms that she's advancing to the next stage.

A pack of Ilgar is sent to storm Border's Headquarters, but most are defeated by the base's cannons before they can reach the base. After Tachikawa defeats one of them, and is sent to battle the Rabbits with the other A-rank members, Enedora complains that they should have destroyed the base, to which everyone says they didn't want to pressure the people of "Meeden" unnecessarily, and simply confuse them.

After Chika defeats one of the rabbits with Izuho's trigger, Hyrein at first mistakes it for a Black Trigger, but Mira states it's not. Mira then explains explains Chika is one of the "chickens". Hyrein then orders Ranbanein and Enedora to go help the Rabbits, and Viza and Hyuse to try and catch the "golden chicken" (Chika), saying they might have found "a new god".

An Rad then creates a interference, and Mira uses the chance to create portals to send her comrades to the battlefield. After Yōsuke, Izumi, Midorikawa and the B-rank agents jointly defeat Ranbanein, Mira tries use her Trigger to attack Yōsuke, but he notices it and dodges, and then she withdraws Ranbanein, who admits his defeat, laughing.

After Enedora infiltrates Border's headquarters, Mira suggests withdrawing him, but Hyrein declines. While he battles Suwa Squad inside the training room, Mira, along with Hyrein and Ranbanein, start discussing Yūma's trigger. Hyrein decides to end the situation as soon as possible, as the Border agents were starting to learn their weaknesses.

Hyrein then decides to go to the battlefield personally, after Yōsuke, Izumi and Midorikawa go aid Osamu and co. After Enedora was defeated, she suggested withdrawing him from the mission. When he was defeated, she proceeded to dismember his real arm, and finally kill him, stating that she was only ordered to retrieve his Trigger.

When Kōhei Izumi, Tōru Narasaka, Shōhei Kodera and Isami Tōma team up to take on Hyrein, she teleports herself to a building nearby, and summons Rabbits to face them, but Shinji Fuyushima warps the Snipers away from the rabbits, while Yōsuke Yoneya and Kyōsuke Karasuma battle the rabbits.
