Ain is the Vice Admiral of the Neo Marines and the second-in-command to the former Admiral Z. She wears a thick, dark hooded cape over a formal uniform and carries herself with a serious, melancholic demeanor. She remains fiercely loyal to her teacher, orchestrating his plan to destroy the New World by detonating the three End Points, and she commands the organization's troops with absolute discipline.

She possesses the powers of the Return-Return Fruit, which allows her to generate pink energy spheres that revert the age of anything they touch by twelve years. This ability affects both living beings and inanimate objects, creating the potential to erase targets from existence if their age drops below zero. In addition to her Devil Fruit, she utilizes dual daggers and firearms, engaging enemies with a highly skilled, acrobatic fighting style.

During her operations, she infiltrates the pirate ship to ambush the crew, successfully reverting several members to younger states to weaken their combat effectiveness. She later stands as the final line of defense at the last End Point, engaging the green-haired swordsman in a duel to protect Z's objective. Following her defeat and the subsequent death of her leader against the Marines, she mourns his loss at his grave, marking the end of the Neo Marines.
