At the Ares space station, Leo Kaito belongs to the lowly Iron class. The Ares Fall tells the story of a love torn apart by the harsh barrier of status. Kaira is a girl placed in a higher tier. Higher here refers to status, not physical location. Their love is never neutral, always surrounded by the pressure of rankings. Implicit limitations heavily weigh on this beautiful relationship. Perhaps they will try to overcome it, or one day everything will collapse.
Meanwhile, strange changes from his mother and mysterious spiritual disturbances are gradually consuming the Ares station. The main character is caught between two different stories. On top of that, the issue of his own status hangs over his head. Will it drive him mad, or will he slowly be corrupted?
