History
Enryu's Thorn is an item surrounded by mystery. Not much is known, solely that it was a massive object found at the location where the Irregular Enryu killed the Forty-Third Floor Guardian. It was somehow acquired by FUG, who found that it was a "dead husk" and could not be used. The organization subsequently worked with the shady scientists of the Workshop to try and find ways to create living Ignition Weapons so that the Thorn could be used to fulfill their objectives. FUG's intention was to give the Thorn to the Slayer candidate Jyu Viole Grace to increase his power and aid them by killing Zahard. However a faction within FUG lead by Karaka decided that this was too risky and planned to merge Viole into the Thorn, activating it in a manner that would allow it to be used by anyone strong enough to wield it.

The Thorn was hidden within an aquatic arena being used for the Workshop Battle Finals. In a turn of recent events the Thorn has been stolen by Jyu Viole Grace. According to Hwa Ryun, the "Fake Thorn" given to Viole acted as a "container" for the real Thorn. When Beta trapped Viole inside the True Thorn's Chamber, it started to slowly react with the original and begun its summoning. It now hovers above Viole's right shoulder in a compressed form, similar to Horyang's wing.
