Lilith is not her real name, and her girlish appearance doesn't represent her true age either. When she was expelled from the world's most famous scientific research institution for secretly conducting biology experiments that were far too radical, she chose to adopt the name of this god-defying witch for her future endeavors in this world.

As her advanced scientific research is destined to never be understood by normal people, Lilith does not pursue a worldly reputation or status, and nor does she want to be bound by academic ethics. To gain access to the high-end equipment provided by the Blackfire Defense and a large number of wounded patients, Lilith joined this mercenary group as a special consultant.
