As a pure vampire, I, Yuu, deviated from the worldly path and had an unrequited love for my brother in the human world. My unbearable fate and the pursuit of my family made me watch the one I loved being killed. My unbearable and broken heart disappeared in the middle of the night with the sound of the subway... When I opened my eyes, I found that I was in the world of Net King, and I was the sister of Echizen Ryoma... And the guardian. The protagonists of Sweetheart and Vampire Knight also appear here... Although I know that I am in the anime world, I can't remember the past life, and I don't want to disturb the lives of the protagonists. I spend every day so carefree. However, fate has made me have that sad forbidden love again... (Since I haven't watched many Internet Kings, the plot has changed, please feel free to comment)
