As we are still getting used to Hades being playable in Blazblue Central Fiction Act 2 we are getting a preview for act 3. As you say in the last post Hades impalement at the hands of Ragna is the start of the third act as we get a small bit of where everyone is at from the second act. At least most as with most story modes not everyone is covered for instance we have no on Bullet but we have word that Terumi and Hazama are walking down their own paths. Noel is losing her mind and Jin is out to kill someone. That small bit and a glimpse at another new enemy is what we entail. Another Noel.
“A couple of things
Act 3 is called: The replacement blue or The Replacement Azure
Here is our next Character for act 3 – The lovely Es. Turns out Xblaze is now relevant
Litchi’s Panda was Roy all along
Naoto is an “offshoot” according to Izzy, and Raquel tells him not to touch the Azure fragment that popped up for him.
Everyone’s wishes are being overwritten by Noel, because she’s learned the truth and is losing her shit, as always.
Rachel’s losing her powers to the point that Raggy’s asking her what her deal is.
Assrail is Izzy’s dog, and has a pact, or something. He want’s to fight Ragna at full strength, says something about it not being the right time.
Mu got fucked by Noel’s issues, and all the blame has been put on her for some shit.
Jin’s gonna go kill defeat “that person”.
Hazama and Terumi aren’t riding the same ride anymore. Hazama trolls him and decides he’s not going to be Termin’s Tool anymore and want’s to be his own self. Turns out he actually did have his memories all along and was merely pretending to be retarded. Terumi wants Susanoo for a vessel, and has the Successor of the Azure for something or other.
In nine’s ending, she somehow was able to gather all of the Noxes. It shows her standing in the center with all of the noxes surrounding her.
Apparently the girl in Amaterasu is the “true Noel”
Izanami impales herself on Raggy’s sword when he was facing her, she goes crazy and tells him to face the truth of the world if he wants to end everything. Here’s the dialog
Ragna: “Wha— Saya…? You, on purpose…! Why!?”
>Izanami: “Fu… Fufufufu…”
>*STATIC*
>Ragna: “!? This is…!?”
>Izanami: “That’s right… A Phenomenon Intervention.”
>Ragna: “That again!? Shit!”
>Izanami: “Before, you said that you would end everything… In that case… Just what manner of ‘end’ comes after my defeat… I’ll have you confirm it with your own eyes…”
>Ragna: “What the hell are you thinking?”
>Saya: “Do not fret… I’m saying I’ll show it to you, my ever-so foolish Brother… Just who the enemy you must defeat truly is…”
>Ragna: “The enemy I must defeat? You, just what the hell are you—”
>*MORE STATIC*
>Ragna: “Damn it!”
>Izanami: “Kuhaha! If you wish to end everything, you must first face the truth! And know! The merciless power of God! Your own powerlessness! At that time, a great manner of enjoyment shall await you… Ragna… Ragna the Bloodedg—”
>*STATIC, BRIEF FUZZY IMAGE OF THE GIRL CRUCIFIED TO THE MASTER UNIT*
>*TIMELINE RESET*”
As always thank you for reading.

Will the master unit Amaterasu will be a playable character? I believe she will be the boss of arc III
It is hard to say as right now this is all based on what has ben gathered from Act 2. Some are saying it is another character from Xblaze.. We will have to wait for some clarity.
