Mentions of fertility issues ahead!
Although Sarah Abadeer and Echo wanted their own child, they struggled to conceive for years. Due to Echo being a sinner and Sarah having her own infertility issues, causing them to struggle to have a child. It was because of this struggle that they eventually adopted Marina, a hellborn demon from the Envy Ring when she was six. But just a year later, Sarah and Echo were finally able to conceive and have their own child.
Iza Abadeer is the miracle child of Sarah Abadeer and Echo. Due to her miracle child status, she was spoiled quite a bit as a child. As she grew up, Iza ended being much more girly than her older adoptive sister. As a small child, Iza loved playing dress-up with her older cousin, Elise II, who she saw as a role model. It was through Elise II that Iza developed an interest in fashion and decided on being a fashion designer when she grew up. Shortly after high school, Iza got accepted into a fashion school in the Envy Ring, where currently attends.
