lilith_(mon-musu_quest!)
One of 2 powerful succubi who were defeated by Heinrich 500 years ago, Lilith (リリス) & Lilim (リリム) are twins who were entrusted by Black Alice (mon-musu quest!) to lead their race to a haven. Lilith is the taller sister with a flat chest, and Lilim (mon-musu quest!) is the big-boobed younger one.
Not to be confused with Lilith (mon-musu quest: paradox), sister of Morrigan (mon-musu quest!) and Astaroth (mon-musu quest!) from the same series.
