The manga is named "Five Star Stories".
True that it is "stories" as its important events are chronologically listed beforehand; but it is more than "Five Stars" as it also covers politics, history, culture, faith and technology. It delivers a story about Amaterasu no Mikado, Lachesis, Knights and Mortar Headd (MH).
MH are piloted and controlled by Knights and Fatima; and among all MH, Black Phanton is worth to note. He is as mysterious and gloomy as the name suggests. His kneeling pose expresses unusual charm of robot kits.
One more thing worth to mention is the story is ongoing since its release in 1986. Still remember how old you were when you first fell into this starry fantasy?
