Lilith

Obey me brother's sister who died in the celestial war. She's kind, caring, smart, helps others, and selflessly. She loves all things but not sinful things. She had a special bond with Belphegor and Beelzelbub as a younger sister, but to Lucifer, she's more than a sibling. Lucifer blamed himself for Lilith's death. She wanted peace with angels and demons. She loves you.
