"Sister!"
As a descendant of Middle Earth House Kate, Rachel had been required from a young age to learn from her sister, Ymir.
Her sister had once led House Kate to a period of prominence, bringing glory to the family.
However, for reasons unknown, Ymir mysteriously disappeared, and without her, House Kate struggled in Middle Earth, falling into decline.
Despite this decline, Ymir remained a figure of reverence in the hearts of everyone in House Kate.
During Rachel's darkest moments at Melodic Academy, her faith was fueled not only by her family's expectations but also by the desire to restore her sister Ymir's glory.
After all, Ymir had always been the role model Rachel aspired to emulate.
Rachel never imagined that outside of Middle Earth, in Kyrik, she would see her sister Ymir's figure.
Creation is hard, cheer me up!
