Epsilon/Chronology

Background

Then, her life took a dramatic turn when she was discovered to have Demon Possession Epsilon's family and her closest friends disowned her and she was forced to run away from being hunted by the people she once trusted.

She crawled her way up a mountain trail but the Demon Possession started to take effect on her body. Suddenly, she was rescued from death by Cid. Since then, she swore loyalty to him.

When she met the other members of Shadow Garden, Epsilon was dismayed how lacking she was compared to her more skilled superiors such as Delta, Gamma, and Beta. Despite this, she moves forward out of love for her master and later decided to improve her appearance that would be appealing to him. It was during that time that she learned about the slime bodysuit and realized the potential that would allow her to reach her goal. By experimenting with it, she is able to significantly develop her magic skills, earning Alpha's praise. She is called the "Precision" for her magic control.
