Evelyn is known for being calm, decisive and professional, serving as an irreplacable pillar behind Astra. Though she can be quite serious and protective, she is notably more relaxed around Astra and the Phaethon siblings. While little is known about Evelyn's childhood, at some point, she was brought into the "Organization" where she was trained to be an assassin/spy and performed numerous jobs. The hackerRain also worked for them and became indebted to Evelyn after she saved Rain's life. Her final job was to work as a spy for the company Fugue under the indentity "Scheele's Green" by becoming the manager of Astra Yao. Evelyn was warmed by Astra's sincerity as a person, gradually opening herself up and eventually cutting ties with the "Organization".
