Post-Shinjuku Arc
She appears at the end of chapter 16 with Lieutenant General Kureto Hīragi and Major General Shinya Hīragi (though she is unnamed).

In the following chapter, when Private Yūichirō Hyakuya attacks Kureto from behind, Aoi blocks the attack, albeit some difficulty as she states that he's strong, and saves Kureto.

Nagoya Arc
She reappears in chapter 32. When Major General Seishirō Hīragi gets into an argument with Kureto and gets intimidated by him, Seishirō calls for backup from his soldiers, he sees that Aoi and another soldier already took them down. She informs Kureto that all of the preparations for departure are complete and they can move out any time.

Later, Kureto asks her about the subject's condition and she informs him that the subject is unstable and in severe pain. He orders the drug dosage to be increased to force it back into submission. When she informs him that action may kill the subject, Kureto simply says humanity will die if it does not hold out anyway.

He asks if they have a status report from Lieutenant Colonel Guren Ichinose and she tells him that there's just one: "Everything's fine."
