This is doujin game (fan produced) that was available only at Japanese game shows. To get one you had to place an order in advance; the game would then be made, and you would pick it up at the show. It was not made for the general public.
This game deals with combat in the world of Fang of The Sun Dougram, an anime show from the early 80's.
