Your Vampire Guardian: Song of shadows
您的吸血鬼監護人 ： 陰影歌曲
Most walk in the light, because they fear what is in the dark. And those who walk in the dark may never come to the light. The fine line between these two is, however, why most will never cross. But what would you do if you were given a chance? Would you take it? Or throw it away? Would you find the courage and risk to walk the line? Because if you can, I guarantee, you will find the greatest satisfaction.
