Aiko is Ingrid Asayashi's older sister. Older by 2 years, she is smarter and more well versed in the society and economy of Kusonoki-Yuki then Ingrid, but she is kind and not snobby about it. Pure She/Her, Heterosexual. She's a lot more open and free in comparison to her sibling. Despite her sister being a dolt, she cares just as much for her as she does anyone, but knows people's limits. As an older sibling, she's more defensive and less trusting of people. She even studies magic!
