I Am Batman

-- I became him, my favorite superhero, Batman. Only... as I looked at my small body, I realized I had become little Bruce, whose parents were still alive and whose family was whole. I used to be the organization's strongest assassin, and the one most despised by the outside world. Trained from childhood, I knew neither joy nor sorrow. Whatever the mission, I never showed mercy, whether the target was a man, a woman, young, or old. I turned to look at the Waynes. What should I do? -- Someone transmigrates into young Bruce. He becomes a Bruce with no emotions. Who can save him, and why did he come to this world? -- This Bruce has no emotions. He doesn't understand why people feel sadness, pain, or grief, or why they pretend. He can see into other people's hearts, but not his own. Things will develop step by step. He won't have any feelings at first. There will be a woman midway through, but not in the ending. Theme: I want to see how a Bruce like this will grow
