Elemental Sight, also known as Eyes of the Spirit among the Traditional Magicians in the 101 Independent Magic-Equipped Battalion, is a sensory ability that allows Tatsuya to connect to the Information Dimension and identify the landscape down to every detail. Every person and object imprints their Eidos within the Information Dimension, and every system and type of magic projects Sequences onto the Eidos through it. Because of this, nothing can escape from Tatsuya's Elemental Sight. Moreover, he can identify and examine each and every Eidos and Sequence and target them separately, irrespective of distance. It can be used to analyze any physical device or material at least down to the atomic level and his artificial MCA can dissect even the most secretive magic.
As a result, compared to normal Sensory Magic, Elemental Sight is a Supernatural Power that might attract more attention from Magicians than Material Burst. Only phenomena that obscures a target's information can offer some level of protection, but even then, such protection can be destroyed by some form of Decomposition, either singly or as part of a Loop Cast series. Completely hiding one's information does not prevent detection as Tatsuya will notice the lack of information. Only by disguising information can detection by Tatsuya be possibly avoided.
Coupled with Tatsuya's other Innate abilities, Elemental Sight enhances his ability to use Decomposition and Regrowth with greater precision.
