Don't worry about what I am. What's important is that I can be free now. I saved you quite a lot today. I think I should receive a proper reward for that. Instead of you, who collapses because you can't even handle your own body, I'll take over and use it well. This is strange. I thought for sure I had control. Why isn't it working?
