Thoughts Are Like Swords and Memories Are Written into Books

In this world where gods and demons do not exist, I fell in love with you, the second daughter of the demon world, "I order you as the emperor of the god world, you cannot die... I will save you, no matter what the price!" Let my thoughts turn into a ruthless sword, and let this memory become my belief in fighting for you! I love you, even if there are countless rumors, if you mind these, then I will kill all the people in the world!
