Excalibur Mimic, also known as the Holy Sword of Mimicry, is a Holy Sword and one of the seven Excaliburs.


One of the seven Excaliburs created after the original Excalibur broke. It was then kept by the Church for safekeeping along with another Excalibur. During the events of Volume 3, it was wielded by Irina Shidou before being stolen by Freed Sellzen and fused it with Excalibur Rapidly, Nightmare and Transparency becoming the Fused Excalibur. The Fused Excalibur was then broken in battle by Yuuto Kiba and Xenovia. The remaining fragments and the Excalibur Destruction was then taken back to the church to be reforged by Irina.

In Volume 9, It was later given to Xenovia from Heaven after being fused into the Durandal along with 5 other Excalibur fragments.

In Volume 10, during the Rating Game of Rias Gremory and Sairaorg Bael, Excalibur Mimic was loaned to Rossweisse by Xenovia as part of their strategy against Sairaorg.

In Volume 19, during the battle against Vasco Strada, Xenovia had all seven Excalibur fragments fuse together as one sword, thus recreating the original Excalibur.


Although Excalibur Mimic can take on many forms, it's mostly in the form a Katana with a round gold guard and a long enough grip making it a two-handed blade. When not in use, the user turns it into string tied to the users arm.


While mostly considered a sword, Excalibur Mimic has the ability to transform itself into any weapon and morph into any shape, size and material its wielder desires. It can even be turned into any regular object. It is even able to create multiple life-like sized copies of a living being.


  • In the anime, Irina wielded the sword again during the peace treaty between the three great faction.
