World Opener

"Person Who Opens the World" (世界を拓く者)  is the name assigned to the world's newly chosen Singularity, Julius Visconti's mutated form. This being's purpose is the same as the Nova Apocalyse: to devour all life on the planet.

History
As part of Dr. Rachel Claudius's plot, former Blood captain Julius was deceived into cooperating with her God Arc Soldier plan. Rachel's hidden goal was for Julius evolve into the new Singularity of the planet and devour all the world's life. Julius transforms into this form as part of the the effects of his contracted Black Plague.

Appearance
The top-middle section of its form has Julius's body impaled by a golden crown-like head ornament. The cloak and the six floating blades all gain minimum damage from Blade attacks. The cloak surrounds the inner body core as protection. Only the core in the bluish center of this being is supceptible to regular damage (green color flashes) but is hard to hit due to its small hitbox. This being can use a stronger and wider version of Julius's Blood Art that damages multiple times. The floating blades can be controlled by this being to attack in many directions or to attack its surroundings. This being can also release beams of light that damage any who make contact. Attacking the core repeatedly is the only way to put it in Down state.

Additional Information

 * This battle's BGM is a piano piece titled "Last Battle" that only plays this once in-field battle. The BGM can be replayed in the Archive.
 * The portrayal could be a reference to the tarot card "Six of Swords". Reversed, it is the card of dwelling, fear and cowardice, rather than resolution.
