Libidicus: The Fall of Lust

Lust is dying.

She doesn't want her powers and essence to bounce on to the next random demon, so as she felt herself slipping away, she called a demon who she considered as her son.

After her feeding, she told him what was happening.

She'd pass on her powers and throne to him as soon as she passes.

::

Raised to hunt demonia by a poised pious priest, despite his heart telling him it's wrong; Yeohwan slays left and right.

He mercilessly murders the demons who walk the earth in the near dystopian future;

Only to fall victim to Lust who seems to know more about himself than he even does.
