Worked on the Astral Express as a guard, Friends from March 7th.

Even though his status is the guardian of the Astral Express, Dan Heng is one of the figures who is trusted as an archivist and information seeker at the destination of the train that will dock.

Previously, he was found by Himeko while hopping around the spaceships, specifically again at a port after rescuing a series of starships, where Himeko is one of them.

Does not have a good relationship with the blade (?)
