[spoilers]I'm more confused by the Nu=Black Beast honestly. If Nu is the original Black Beast, then in the original timeline where did the one that originally almost destroyed the world and caused the creation of all of the ars and stuff? Without those there would be no Nu, no Nu means no Black Beast, and no Black Beast means no ars or that kind of stuff and we go back to the first part of this sentence. I liked it more when the Black Beast was not ANOTHER future past version of a known character x__x[/spoilers]
Not quite sure you worded that right...
But if I get what your saying she was always it.
Everything starts at
A.D. 2199: Nu absorbs the Blazblue, and solely becomes the Blackbeast. Nu, Ragna, and Jin are transported to the past.
???????: Rachel puts Jin's soul into the Susano'o unit.
-2100: Hakumen and the Black beast arrive, but the BB is still stuck within the boundary while Hakumen is out and about.
-2106: BloodEdge appears with no memories. By the looks of the images, he was friends/close with a lot of the past people. Such as Konoe and her sister, and Rachel's father.
21XX: Relius and Shuuichirou use a Interface Prime Field Device (A murakumo units like Mu, Nu, Lambda, etc) to research Kusanagi, and ended up releasing the Blackbeast.
21XX: Blackbeast destroys most of the world. Bloodege Single handedly stalls the black beast for a year (LIKE A BOSS!) while the Konoe teaches humans magic, , etc. Nol is formed. Black beast is defeated
-21XX: Terumi kills Konoe, and tries to trap Jubei and Hakumen in the boundary. Terumi ends up getting stuck in there instead of Jubei.
It then goes on a 100 years later as we all know, only for it to repeat itself over and over again until the one repetition where Noel DOESN'T die during the experiment. (She dies in every single other world/version of it. But after so many her chances would grow little by little till she finally survives). Rachel also saves Ragna from Terumi by sireing him. From what's been said, this was not an event in the original time line before she knew "THAT" bloodedge.
A.D. 2199: Noel this time saves Ragna from falling into the cauldron. This results in stopping the creation of the Blackbeast, and the 3 being sent to the past. At the same time, Jin no longer dies when he should have and never becomes Hakumen.
A.D.2200: Saya destroys the master unit, and ends the continuum shifts. CS Ends.
