Lily

Lily is the boss of the Witch Hunt Village quest in Monster Girl Quest. Her personality is rather confident on the exterior, but when she gets down to her personal motives, she seems to be a mistaken and troubled individual who feels as if the world should suffer because she has. Luka manages to defeat her before she can cause any more trouble for the village, as well as leaves the village to judge her for her actions. However, the villagers state that she would not be killed, for they did not wish to continue the cycle of hate.

Lily is technologically powered to create monsters out of human girls. The failed experiments transform into the Suck Vore, while the successful ones transform into either Village Girl or Iron Maiden creatures.

It is later revealed, if you return to the Witch Hunt Village after Lily is defeated, that Lily's revenge scheme was powered by the angel scientist Promestein.

TRIVIA:

Her appearance greatly resembles Rydia from Final Fantasy IV.
