Dimension Manipulation is an expert-level aspect of the Hazama-Ryu Kekkaijutsu. Experienced Kekkaishi are typically able to manipulate dimensions to some extent. This includes the creation, use, and maintenance of portals, as well as the navigation through, and repair of, damaged dimensions on the verge of collapse. Because of its high degree of difficulty and potentially grave consequences, dimension manipulation is usually taught to younger Kekkaishi by their elders while under close supervision.
