There were a few Japanese animes that involved elements of shadow combat. One of them was Blue Dragon, which was broadcasted on television around 2000. The protagonist was a teenager who could summon a shadow to fight through a device on his right hand, but the shadow seemed to only appear on the wall behind the protagonist. There was also an animation called Saint Robin, which was broadcast between 1989 and 1990. The protagonist could control shadows to fight enemies. In addition, the shadow ninjutsu used by the Nara clan in Naruto also involved the elements of shadow combat. Other than that, the other search results did not mention the specific name of the animation or related information.
