Prior to Irene memory restoration, Yasaka and Kunou was overwhelm upon waking up in the past where everything was more peaceful. They immediately tried to see the current situation and found a letter where Yasaka read about the situation from Irene.
She and her daughter hugged tightly having a second chances with Issei who was their husband in the previous timeline. Though Kunou dislike having petite body once again but she can always Issei to fix it.
After reading the content of the letter, Yasaka immediately called for a meeting to prepared the faction of upcoming plans. She told those most trusted about the situation and able to convince some them about it. They believe her due to how mature Kunou acted suggesting about Issei being an ally.
She was doing a better job at handling the situation than Issei is due the Fact the latter's mind was a bit unstable after being exposed to the outer gods erosion but time had manage to remove it and able to change his plans.
Issei realized that the outer gods was influencing his action by a bit which is why he refused to restore his lover memory and able to remove the influences after regain his strange. Now that he had Sirzechs use his influences in preparing people at the upcoming battle with the outer gods.
He only doing it for them to survive and not win as Issei knew he was the only capable one. Though it doesn't mean that his lover won't catch up soon.
Back to Yasaka, She was able to formulate the Youkai faction in contacting Amaterasu at the Shinto faction which was her most trusted friend. She was one of the head of Shinto faction which would be a huge help from preparing from an enemy such as Khaos brigade or Alliances of hell.
Getting into contact with her immediately responded to the call. The next Amaterasu arrived and question about the reason of the urgent call and told about everything. She was bewildered about the information that her friend spoke.
"Are you sure such a catastrophic event would come? This is too much to handle, Yasaka-san."
"I know even I am overwhelmed with this memory but I am sure everything will happened and we need to prepare."
"Your almost saying an ant fighting a monster??"
"It feels hopeless but I believe my Husband is doing the best he can."
'Or his busy with his other woman if they gain their memory….Just wait Anata~'
"Husband? I never heard you gotten married again? Or is this related to the future?"
"Oh yes my husband is the current red dragon emperor and a harem king. Guess if your part of it or not fufufu."
"Don't joke around, Yasaka-san. If I was part of your husband harem then I'll have my memory."
"Ara~ but why are you blushing? I don't mind my husband courting you since it would allow your shinto faction to have the backing of the Red dragon emperor."
Ametarasu tried her blushed from her best friends teasing but deep down she was curious to meet the person capable of becoming a powerful individual in short amount of time and even courted her best friend.
"We're getting out of topic. Tell me Yasaka how are you sure that this memory isn't just some dream?"
"I know of it because everything was too real."
Yasaka paused a moment remembering her time with Issei how he always there for them and helping her through the end. She married him because he was someone who tried his hardest despite everything. The final moments where she died along with Kunou seeing his grieving face after losing so many.
He held their hands and promised to lived while protecting the rest. Yasaka wonders if Issei able to remain happy without her but she knows the answer and how much pain Issei had face.
"Yasaka are you still there?"
"Ah I'm sorry I was lost in my thoughts. What were you saying again?"
"Nothing, I believe you after seeing how this information is affecting you and I know your retainers notice as well. I'll try what I can about my faction however many would likely refute."
"Hmph it would be there end if they don't listen ignorant old fools. Ametarasu be careful once you discuss this information with them as I am unsure who are true enemy."
"I know. "
Ametaresu stood up letting her long kimino dripped down while exuding her divinity of the sun preparing to return.
"Can you tell me the name of your husband?"
"Issei hyoudou."

Upon securing a safe place, Rossweisse began to tell everything prior to the upcoming calamity to their world. Odin was baffled from the news he receive since Sirzechs had given similar report with vague information. Now everything was slowly making sense since Rossweisse provide solid evidences to it.
He was skeptical about the sudden suggestion for cooperation of the devil faction but now understood how dire everything is.
"Are you alright? I can already see that you experience something terrible?"
"It is as you say, Odin-sama. I wonder my husband is doing if he as well his memory."
"Huhuhu did you said you gotten a husband and not boyfriend? I thought you won't ever get one."
"Hahaha it won't work on, Odin-sama."
"Let me guess you panic at your first time?"
"EEEEHH what are your saying, Odin-sama."
"Hahahaha I guess it's true! I wonder what kind of man that my granddaughter took?"
"His…An amazing man never giving up in the face of the impossible odds always smiling and….screaming about boobs."
Odin was intriguing about her description of the man but quickly went down the drain when he heard about screaming boobs. He laugh out loud for ridiculous kid to make Rossweisse fall in love.
"Hahaha what kind of kid screams boobs? Did he shout his love for the magnificent breast of a woman?"
"Always though he did outgrew it since we kept him company."
"*Sigh* I will handle everything, try to relax Rossweisse."
She only nodded deciding to rest in her room while to calming her mind about everything.

Issei was preparing some tea and snacks for them have when see Yasaka along with Kunou and Rossweisse in a daze. He smiled knowing they are overwhelmed by his new appearances.
"I-Issei what happened and how can you become more handsome!?"
"A-Anata is that really you? You've became more….attractive!?"
"Yeah kaa-san right! Also Issei please make my body into an adult!"
"Don't worry, Kunou. Here used this as temporary."
Issei then gave her cupped tea before placing a magic pill that could make any grow in an adult. He had made it while experimenting with sacred gear and knew Kunou would want it.
Upon drinking the contain instantly change into an adult ripping her small clothes but Issei used his magic to create clothes for her size. What appeared was an adult form of Kunou with long blonde hair wearing a white kimono that had petal patterns to it.
"*Sigh* thank you Issei, having that child body made my mind degrade into one. "
"Your welcome. Now then I will tell you everything that had happened to me."
Issei sat down after pouring tea to everyone's cup. He began explaining everything after their death and the ability to create Sacred gear had shocked them. They saw him brought out a small needle hovering that quickly free in size into a long crimson red spear that had two prone.
"This is my other sacred gear, Ayin, The spears that end nothingness."
Afterwards, he hid the spear to his pocket dimension and resumed his explanation until the present. They were mad that the other girls and their turn on him but calmed them down.
"If your really sorry then let head to bed!?"
"Hahaha alright we must hurry before the others gets back."
