Akari

History and Family
Akari lived in the world beyond Hueco Mundo, a world created so the Ser Transcendte(higher than Vasto Lorde) would not kill every hollow by being next to them, she was taken care of by Tentei Moeru as a Gillian, he gave her hollows to eat so she could become a Ser Transcendte, he could be around them beause he had mastered the skills of supressing one's power and was a Ser Transendte Arrancar who uniquely remembered his past. She became Vasto Lorde like her sister Hirameku to attain the power needed to see her father, Tentei Moeru so she ate and ate to become as strong as can be and gained a friendly little hollow, in the form of a cat. This cat was the soul of a kitten and ate hollows till she became of equal rank, however since it does not carry the same power a human soul has it became her pet, she then became an Arrancar similar to Hirameku.
