Vermillion Empire Edit
Mirillia, along with Tilmitt Gracie, ambush Ikki, who has just entered Vermillion, on a roof. They tell him that there's a reward placed on him, worth 100 million yen. She then shoots Ikki with her gun, while Tilmitt dives into the roof with her Noble Art. Initially they have the advantage, with Ikki even complimenting their teamwork. Despite this though Ikki defeats them, and repels Miriallia's bullets, by causing an offset in their kinetic energy by hitting them with the exact same energy.
