Emiya's Dual Swords

Unlimited Blade Works: Infinite Creation of Swords (無限の剣製アンリミテッドブレイドワークス, Mugen no KenseiAnrimiteddo Bureido Wākusu^?, localized as "Universe of Endless Blades") is the Noble Phantasm of EMIYA.

It is a high-class magecraft that embodies the user's internal worlds and imprints them upon the World as a Bounded Field for a short amount of time. It is their one true specialization of magecraft, the result of the concept of swords being both their Origin and their Elemental Affinity, and the basis of their Projection and Reinforcement skills. It is the definite ability obtained by someone whose life was saved by a sword, actually merged and lived with a sword, and acted as a sword all of their life.
