The Apocalyptic Power Flood
Just by being born as a member of the infamous Vetrov family had automatically put countless limitations on her life as Evelina Vetrova no matter how hard she refused to involve herself with the organization. Although she had always dreamed of a better life of freedom pursuing her passions and dreams without any worries, her actual living situation prevented her from believing that she could actually achieve her ideal life. Her environment during that time had instilled the concept of impossibility deep within her.
It was only when Cross Academy recruited her as a student that her mindset drastically changed. She might not have studied in the campus but the remote education she received wasn't inferior to the other students. She began to finally believe that anything was possible as long as she was creative and determined enough to think of ways to make the impossible possible.
