Uchime (内目, Inside Eye) is a technique unique to Kazuma Nishiki, which enables him to "see" despite having been blinded by Vincenzo Montferrand in Hueco Mundo. It functions by using the Tsuji sensory technique in conjunction with exerted reiatsu and ambient reishi. Kazuma thus sees the expression of physical objects in his mind and can react to them much more effectively than a person capable of full sight, ensuring he doesn't bump into things on the street or an opponents blade during an engagement. In terms of spiritual objects (and entities) he "sees" the outline of their body bathed in reiatsu, though even with reiatsu-masking technology he can still react thanks to Onkyōkyū.
