Opera's little Sister (welcome to demon school)

Y/n is the little sister of Opera, who works of Lord Sullivan. Y/n has been with her ever since Opera started working for Lord Sullivan after Opera grauated from the well-known school called The fiendish Babirus Academy.

it wasn't long when Y/n turned 14 years old that Opera had enrolled his sister at The fiendish Babirus Academy.Since Y/n is a beast demon she is similar to her older bother. Some teachers at babirus say that she looks at a acts like opera. Except for that Y/n has longer hair and that she wears dresses.

When Iruma came around this started to change in the house hold and there is a bit more energy. To Y/n's dismay that is.
