They are the strongest.
The protectors of humanity.
The ones entrusted with justice.

They are Heroes.

But power corrupts.

Behind their titles and reputations hide ambition, violence and secrets.

Since the death of her sister, Ihwa has lived for one purpose: finding those responsible and making them pay.

As she hunts the Heroes who shattered her life, she will uncover a world where justice is just another weapon, and where the line between Hero and Villain no longer exists.

In a world ruled by corrupted power, one woman is ready to fight back.

Welcome to HERO KILLER.
