It was stated to be an experiment to connect with the Boundary using a Dimensional Boundary Contact Prime Field, which ended in failure, but it actually was an attempt to create a Black Beast to use it against the World Void Information Controlling Organization. The Takamagahara System used their Arch-Enemy Event Weapon, Highlander: Takemikazuchi, to prevent the birth of the Black Beast, and annihilated Ibukido.
The Contact Prime Field which was used in the experiment, Mu -No. 12-, was saved by her cocoon, but her smelting was interrupted, and she lost all her memories because of that. She was later adopted by Edgar and Claire Vermillion, and was named "Noel Vermillion".
