"Aaaaa..."
As Rashomon trembled violently, the great goddess Tiamat was attempting to enter this small world within the Sea of Imaginary Numbers.
Accompanied by a series of creaking sounds, Ryuya could sense Rashomon's helplessness. As an S-rank Noble Phantasm, Rashomon was a peerless holy artifact that had sealed countless Oni for a millennium.
Unfortunately, Ryuya's current physical power was too weak, so the Noble Phantasm couldn't unleash its true strength, which was why it was so vulnerable against Tiamat.
Although, even at its full power, Rashomon would likely struggle against Tiamat.
"Rashomon, let her in."
After Ryuya spoke these words, he watched the colossal figure rapidly shrink until she became a stunningly beautiful girl, looking about seventeen or eighteen years old and roughly human-sized, walking towards him.
Although her mouth produced the incomprehensible 'Aaaa', the meaning was conveyed directly to his soul.
He understood she was asking who he was. Ryuya looked at Tiamat, unsure how to answer.
[Meeting Tiamat, you finally realized you were born in the Sea of Imaginary Numbers. Looking at the sorrowful Mother of Origins, you didn't know how this world's Tiamat came to be.]
[But it was clear Tiamat had been abandoned. Feeling her lament, her sorrow, her resentment full of being 'abandoned by her own children', you recalled all your past experiences in this moment.]
[The young Yukinoshita Yukino, neglected by her parents, living a life like a doll.]
[Morgan le Fay Pendragon, cursed for her mana, lonely as a witch.]
[The Succubus Merlin, born in dreams and wishing to perish in them, seeking false happiness to fill her inner void.]
[Artoria, forever bound by the king's duty, knowing the future yet choosing to bear it courageously.]
[Vivian, observing the world, merely a performer dragged into the fray, developing emotions she shouldn't possess.]
[And Vortigern, Uther, the people of Britain, Rashomon's millennium-long obsession, the youkai of Japan...]
[Based on your past experiences, you could understand Tiamat's hatred born from abandonment and feel her pain.]
Under the swaying light in his palm, he looked directly into her starry eyes.
Although he saw chaos and void without reason or personality within them, Ryuya found Tiamat was still protecting him. The chaotic tides outside were all blocked by her.
Even without personality or intellect, she still instinctively protected 'her child' simply because Ryuya was human.
"Who are you?"
"I am..."
An intense sorrow welled up in his heart. Reaching out, Ryuya grasped Tiamat's hand.
As their fingers intertwined, Ryuya spoke: "I am the one who has come to save you, Tiamat."
"The one who saves me?"
After a brief moment of astonishment, Tiamat seemed to hear something unbelievable.
"The one who saves me? The one who saves me?"
"Will you abandon me?"
Lowering her head again to look down at Ryuya, the Mother of Origins asked.
"Will you cast me aside?"
"Will you harm me?"
"Will you reject me?"
The rapid-fire questions stemmed from soul-deep interrogation. Already betrayed by the gods and even rejected by humanity, Tiamat had been imprisoned in the Sea of Imaginary Numbers for endless eons.
Her reason, wisdom, and personality had faded, leaving only instinct. She looked at Ryuya, seeking an answer.
"I will not abandon you."
"I will not cast you aside."
"I will not harm you."
"I will not reject you."
The distance between Ryuya and Tiamat gradually closed until he could feel her breath, although Tiamat didn't have the concept of breathing.
Looking directly at her, Ryuya said slowly, "Tiamat, my name is Ryuya. I will always love you."
…
[Finding the love and everything she craved in you, Tiamat, who had lost her personality in the Sea of Imaginary Numbers, began to follow you from this moment.]
[As the Beast holding the Logos of 'Regression', influenced by your existence, Tiamat began to change.]
[Using Self-Modification, she altered her Saint Graph, no longer the majestic form over 60 meters long, but transforming into a normal human-sized form. Although this process took some time, within the Sea of Imaginary Numbers, time was not an issue for you.]
[Simultaneously, because of your presence, no longer clinging to the past, and having developed a new personality by your side, Tiamat also abandoned everything she once obsessed over. She no longer even sought regression, simply accompanying you as your beloved.]
[In Tiamat's view, the gods abandoned her, humanity forgot her. Previously, driven by a mother's instinct, she wanted to protect this world. But clearly, rejected by the entire world, she no longer wished to cling to past obsessions.]
[Regaining her reason and birthing a new personality, the only thing this Tiamat pursued now was to remain by your side as the 'One and Only' Beast.]
[Redefining the meaning of her existence and transforming herself, Tiamat was no longer even rejected by the World. She could return to the land of Mesopotamia, descending as a goddess.]
"Tia, let's go."
Having stayed in the Imaginary Space for an unknown length of time, Ryuya was now fully grown.
Although he didn't possess the bloodlines of fairy, Red Dragon, or White Dragon in this life, his authority as the Sun-Crowned King played a huge role.
As a human, he could be considered at the pinnacle, with all his parameters surpassing even his Britain era, breaking through A+ to reach A++.
"Mhm."
Staying by Ryuya's side, Tiamat appeared in a normal human form. Even the massive horns on her head had become small, cute black horns.
After all, constantly carrying those huge horns was somewhat inconvenient for her... reproductive work with Ryuya.
Although she was the Mother of Origins, born from Heaven and Earth, and had 'sculpted' all the gods of this world, this was her first time experiencing these never-before-touched matters.
She never doubted or questioned anything about Ryuya. Just like the moment they first met, Tiamat deeply believed Ryuya loved her, and she loved him.
Her pale fingertips touched the node leading to the world of Mesopotamia, and their figures vanished from the Sea of Imaginary Numbers.
