A renowned and longest-serving Prima undine, she co-founded Aria Company with Aria Pokoteng after realizing she was missing out on much of life as Himeya's top ace. Serving as a Prima undine for 30 years, she mentored Alicia, her last disciple, to whom she entrusted the company upon her retirement. Highly respected by young undines, especially Alice, she currently resides in the countryside, engaging in farming and occasionally visiting Aria Company with produce from her fields.
Before mentoring Alicia, Akino had another undine named Anna as her student. However, Anna fell in love with one of her customers, married him, and relocated to Burano Island.
