Danheng is a cold and reserved young man who wields a spear of Cloud-Piercer and has a rather blunt way and elegant way of speaking. He is the train's guard on Trailblaze journey. He carefully observes the changes in everything around him, albeit with a calm demeanor. Danheng faithfully records everything they encounter on the Trailblaze path in the Express's archives. Danheng rarely even talks about his past. Additionally, he joined the crew of the Express to escape from his past too actually.
