To increase the survivability of mercenaries who are participating in the missions, Warcorp recruited soldiers specialized in rescue and evacuation missions. Ophelia is one of those mercenaries. She also goes by the nickname 'Lollipop', due to her habit of always eating a lollipop before she heads out for a mission.
In the past, she served with the JSF Eastern Asia Dispatch as a helicopter pilot. With her vigorous and confident personality, she was a professional soldier. However, she was dishonorably discharged after disobeying an order to attack a residential area where terrorists were hiding. (A girl from that village gave her a lollipop. Since then, she eats a lollipop whenever she is concerned or before going out for a mission.)
She is a true believer who is willing to sacrifice herself without any hesitation. She realized that the JSF didn't value her belief that 'the powerful must protect the weak'. Even if she had a chance to recover her honor, she chose to be dishonorably discharged. Now she has decided to join Warcorp as a mercenary, considering it an opportunity to pursue her faith.
