What would happen if one day you found that the world you live in is filled with demonic beasts and that you are powerless? Would you struggle to survive in this madness? Or perhaps you would do something to save mankind? Well... they can rot for all I care, and instead, let's watch others suffer then!!

Adela is a child who lost all of her acquaintances, friends, and even her family to the hand of those beasts, but... she doesn't bear the hatred for them just that... she becomes broken inside after experiencing such horrendous things. As one who lost oneself, she prays to the gods, but it all comes in vain. Her family and friends could not be alive anymore. Driven by depression and resentment for being incompetent, she wants to die to end all of this suffering. However, when she thinks it's time to let go and she can finally go and meet her family, a man jumps out of the blue and saves her. He is an odd guy who wears black armor with a tattered cape fluttering in the wind. He rips and tears all the beasts as if they are nothing but paper in front of his eyes.

"Will you become my master?"

He knelt before Adela and politely asked that no one could think he had just wiped out a beast wave. But as time passes, Adela discovers the truth behind the curtain of this world. A girl who suddenly has a servant-master relationship with the black knight begins her journey in this mad world. Watch how this girl and her knight travel on this world where suffer and despair took place!
