NXGen Research Facility is first mentioned by Seraphina's Maid. Seraphina's father, a business partner of NXGen, wanted his daughter to apply for an internship there, but her application was rejected. During the Monster Arc, the Newscaster reported that two months prior, a top secret research project funded and led by the authorities that NXGen was working on had been put on hold, and much of the research data and equipment was either stolen or destroyed, leading to a hiring freeze.
