Heiji was pulled to the shadow world by a world thought calling himself Shadow. Facing him, Shadow did not give him any other options. He only asked him if he could save this world that was about to collapse. Heiji chose to stay because he had encountered countless similar incidents before, and the consequences of not solving them would definitely make him uncomfortable for a long time.
