Lilith

Lilith was a goddess that aided Beelzebub in his quest to find and kill Satan, motivated due to the death of her dear friend Lucifer. Lilith is a very assertive woman, who does not back down easily. When she first met Beelzebub, she told him she would aid in his search for Satan and would not take no for an answer, telling Beelzebub that what she was offering wasn't a request but an order. She is also a very kind and forgiving individual, shown when she comforted Beelzebub after a nightmare he had regarding Satan.
