it's a manga, I forgot everything about it but the fact that the mc(?) have the power to control people's mind and make them kill themselves(?) he's looking for someone who can not be controlled by him(?) to end his life(?) and there is this police officer who can do that, but he won't do that because of the sense of justice(?) oh, and one more thing...
