Level Upper Arc
She debuts in Volume 3 of the manga during the Level Upper Arc. She is excited to learn that Hitotsui Hajime is holding his first live concert. Mii doesn't seem to care since idols always just lip-sync during their live shows. Aomi suggests they go anyway, but Mii is distracted by some music that is being broadcast throughout Academy City.

Here, she first gets a call from Mii who asks her what she thinks of Academy City. It is here that is likely that Mii asks Aomi the favor of asking Judgment to participate against the Silent Party and protect the Academy City Research Exhibition Assembly venue from STUDY. She somehow has the authority or seniority to do this, and she later rallies a countless number of them just after the break of dawn. She later participates in the battle, preventing the Powered Suits to enter the venue and delaying them until Mikoto finds a way to stop STUDY completely. She acts as the field leader during the battle, sending out commands. When STUDY later hacks into their communications and Edasaki Banri and other telepaths volunteer to create a communication network for Judgment using telepathy, Aomi apologizes for the bother but Banri says she doesn't mind.

She later observes much of the events that transpire as the Powered Suits deactivate.

She briefly reappears on September 2, while looking at the sky together with Mii from a window of their school.

Aomi and Mii are aware of what Kuroko and Uiharu are doing on account of how they have been in many incidents as of late. They are relieved that the other Judgment branches are willing to help them but laments how they cannot notify Anti-Skill without any real evidence.
