Born and raised by Lilia Greyrat, Aisha's personality is more of an adult than those of her age, able to act and speak in the manner of a maid. She is smart, manipulative, cunning, cute and without any regard for what happens to her subject. At one point she worked Ruijerd to the point where he complains, manipulates Rudeus into giving her his side of the story, and escapes the castle by herself.

She has a playful personality and a major brother-complex as she sometimes make suggestive comments towards Rudeus and has no problem being naked in front of him when taking baths together.

It is revealed that she likes gardening, and cute things but usually forbidden by her mother over maid duties.

Since Aisha is technically an illegitimate daughter of Paul, she has an inferiority complex and thinks that her family does not love her as much as Norn. This causes Aisha to be hungry for attention and very competitive with Norn. This is further reinforced by Claire Latreia, her step-grandmother who looks at Aisha with disdain and gets angry at her for being more talented than Norn. Due to these factors, her relationship with Norn isn't good.


Born out of wedlock between Paul Greyrat and Lilia Greyrat. In the metastasis event, she was teleported alongside Lilia into Shirone Kingdom as such she was mostly raised by and looks up to Lilia. During their time in Shirone, Lilia had trained Aisha to serve Rudeus as a maid in the future. Aisha, at the time, did not want to serve her elder brother that she had never met and likewise, doubted Lilia's stories about him.

After Rudeus saves Aisha and Lilia from Shirone Kingdom, Aisha is impressed with Rudeus and decides to serve as his maid of her own volition. It is also revealed that the reason she did not want to serve Rudeus before was because she thought he was a pervert that treasured the underwear of young girls.

Power and Abilities


Being a talented girl, by the time she started living with Rudeus she was at Elementary rank for all six basic magic types. It is stated that Rudeus spends a good deal of his free time teaching magic to Aisha, though no mention is ever made about her skills improving.
