Immortality (Black Butler)
Immortality comes with a bad price. If you sell your soul, you sell you life. For Vivaldi the price was even worse. Instead of having to live in hell, she must become a grim reaper. It's the worse job a person could get, for anyone. But, for Vivaldi, she's happy to do it as long as she's immortal. She must kill the innocent, elderly, children, and just about anything else. Just as long as the jobs done. If the three mega demons say someone's life is almost over, she must kill them, no matter what. But, what will happen when she runs into a demon butler that is protecting the life that she must take? Will she give up her immortality, or keep trying?
