零

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.
