Gremory, Millicas
Summary
Millicas Gremory serves as the son of Sirzechs Lucifer and Grayfia Lucifuge, as well as the nephew of Rias Gremory. Although his father holds the title of Lucifer of the Four Great Satans, this specific designation is reserved exclusively for Sirzechs, meaning Millicas retains the Gremory surname. In terms of succession, he stands directly after Rias in the line to become the head of the family.
