After artoria left, caster took sakura towards her own room allowing her to rest. He contemplated whether or not should wake her and inform the current situation. But at the end decided to wait for her eventual awakening. For this was too important for her own future. Daylight seemed to have passed now close to an evening. This was the time around which sakura had woke up.
"Onii-chan.."
Seeing sakura drowsily wake up from bed, Ainz could not help but chuckle. It felt to him that even if the world would end she herself would remain the same. As such Ainz could not help but dote on her.
After a few moments of idle banter, caster decided to talk to her about the main issue.
"Sakura, I will be leaving tonight."
Sakura without understanding decided to ask him where and expressed her desire to follow.
That's when he spoke "I am thinking of leaving this timeline or more specifically this world, sakura. As you see I, Ainz Oowl Gown is not a normal servant but something which could exist due to the authority of a higher being. I possess the means to leave the world at my will. For such my time here depends on however I will spend it"
He continued "As such the end of my time seems to be quite near. So, I am here to ask you, sakura. will you follow me?"
Sakura seemed unsure of what she should do. For her everything was happening quite rapidly. Ainz mentioning his desire to leave as well as asking her to join him in his endeavor.
She quite frankly thought about his proposition. She had none who she would call her family more. A girl all alone without anyone by her side and a man if not anyone he himself would move for her.
No!! She does not want to be alone, not after she had tasted what it felt to be loved. If Ainz, her only friend and family wish to depart from this place then at his behest she too wishes to follow him. For the future beside him would not be that bad.
Together and forever. An ideal where she too could be happy.
Driven by her thoughts she came to her conclusion of an answer which would never have been needed. She trusted him and believed in what her servant thinks would be best for her.
"I will. For you are the only one for which I would give all and thus such question is truly un-needed " she spoke with conviction.
Feeling such sentiments from sakura. Ainz for the first time truly knew how much she cherishes him and as such he vowed once more to protect her from all that wishes to do her harm.
Ainz took out a few candy bars from his pocket dimension and told her,
"Then let's go we have no need to lose any more time."
Ainz held sakura's hand gently and teleported her towards the dojo where artoria seemed to be waiting for the duo to arrive.
"Sorry, we are a bit late."
Seeing small sakura behind caster nibbling on some candy made artoria's eyes narrow,
"For what reason is she here?"
Sakura was flabbergasted for such development was truly a new experience to her. Ainz in her stead decided to speak " She comes. For their remains nothing in this world for her benefit"
Artoria accepted his reasoning for it was thanks to caster that she could even foster such a dastardly idea of leaving the world and nodded towards him to begin.
Ancient words began surrounding Ainz, sakura, and artoria in a circle while moving at a speed closer to a kaleidoscope. Runes began shimmering around them as well as disappearing and reappearing over and over. A spectacle never before seen now shook the world of its very core foundations...
"The ebbing of a lost time forgotten in space,
Watchers of life revel in honor for you time shall move like none other,
Blades to blades,
Conflicts from conflicts shall reverse once more,
For the Age of Regression has begun"
Ainz knew now after receiving the blessings of Gaia that his time stop became so potent that through the use of an aria he could very well reverse time and now such phenomenon was occurring in front Artoria herself.
"Super-tier spell " Time Stop ""
And the world was no more...
The clock moving backward at a rate unknown to humanity. A call was made and time heeding of such reversed in its order. In its wake cities, houses, nations themselves began to wither away like the sands of time. Moving without any means to an end.
Reality itself began to shift. Creating and stitching itself over and over again. Conflicts undone, battles forever forgotten, sorrows and despair of rulers depicted in the past rose to ashes and a new history has begun.
Due to the sheer force of the spell Artoria's body itself began to regress to match her own timeline. Changing her from her own mature self to a simple teenage form she once had before wielding the sword from the stone.
Before she knew it Artoria was there once again. A place before it all began.
The sheer influx of pain, sadness as well as happiness for seeing the fulfillment of her own wish brought tears from eyes.
A fate moving once more in a different timeline...
.....
Double release!!Double release!!
I'll let your own imagination decide which arc it truly is...
