Background / History
Ain was one of Zephyr’s most trusted subordinates and had followed him for years. A survivor of a tragedy involving his students, she knew Marine procedures well. Zephyr assigned her to Bane because the newly appointed Vice Admiral needed an experienced aide. Ain pledged to protect what Zephyr held dear—including his foster son, whom she privately called “Young Master.” Zephyr instructed her to be mindful of that address in public 154.
She remained Bane’s adjutant as his standing in the Marines grew, handling intelligence and acting as an intermediary with prospective recruits. By the time Bane’s group reached the Empire, she chose the Shadow-Shadow Fruit to better protect him and support him from behind the scenes 204 314.
In Soul Society, Ain joined the 9th Division as an ordinary member but functioned as Bane’s secretary. She also belonged to the Isshin Society and reported to Bane on its activities 514.
