My youth story, a crossover anime, turns out, is FGO!

The sacred and liberating flames, fueled by the life and soul of the saintess, completely engulfed Tiamat in her dragon form.

After her head was fatally struck, Tiamat was at her last gasp. She cried out in agony, but it was too late to save her.

Crimson flames enveloped her, burning her body and soul, but what she felt was neither hatred nor murderous intent, but rather Joan of Arc's profound compassion.

“Arrrrrrrrrr……”

Tiamat let out a futile sound, which gradually faded as her sixty-meter-long dragon body swayed, changed, and dissolved in the crimson flames.

"Is this a win?"

Hachiman Hikigaya asked, stunned, with a sense of unreality in his voice.

"not yet."

Taigong Wang sighed slightly, his dark eyes filled with solemnity: "The threat to humanity is not only Tiamat, but also Lahem."

From high above, you would see the seawater, which had turned pitch black, slowly turning back to its original blue. After Tiamat's defeat, the Chaos Tide began to slowly disappear, but this did not mean the end of everything.

"Chirp chirp chirp chirp!!!"

Laughter echoed from every corner of the sea. Having lost the instinct to support Tiamat, the more than 10 billion Rahms that had been accumulating over the past few months were completely out of control.

They are real monsters, not products of magic, and they will not disappear even if Tiamat is defeated.

At this moment, these ferocious monsters all went into a state of frenzy. They surged out of the seabed and attacked the land recklessly. The dense, dark Rahm swarms turned into a new chaotic tide, covering the entire sea surface.

"For Mom's sake, revenge—"

"Revenge! revenge! revenge! revenge! revenge! revenge!!!!"

"Kill all humans! Die ...

Just as Makoto Aoki feared, even if Tiamat was defeated, the remaining Rahm would become a great enemy of humanity.

In some ways, Tiamat's abilities, such as the Womb of Beasts and the Sea of ​​Life, can sometimes be more troublesome than Tiamat herself.

These intelligent, powerful, and numerous Rahmites will become humanity's greatest enemy. Even if the land is not conquered this time, as long as the Rahmites learn to hide, those who can conceal themselves in the deep sea will become humanity's most troublesome foe, after all, they are the children of the Salt Water God.

At that time, the ocean and the airspace above it may become a no-go zone, and all countries in the world will be divided and isolated. Apart from countries that can support themselves independently, the modern system may collapse in an instant.

Moreover, the Rahm will inevitably launch a counterattack. As long as they remain hidden in the deep sea, they will eventually turn against humanity.

Can heroic spirits really remain in reality for so long?

The summoning of Heroic Spirits was to deal with Tiamat as a Beast. After Tiamat disappeared, they could not stay in reality for long unless the next Beast appeared.

But what kind of disaster will the next beast bring to humanity, which is rebuilding from ruins and suffering heavy losses?

To avoid that future, Makoto Aoki had thought about it and finally came up with a solution that was hardly a solution, though he himself wasn't confident it would succeed.

A red magic circle unfolded on their clasped hands. Taigong Wang adjusted his spell and opened his eyes.

"--Analysis begins, spell unfolds, remote contact with the target's spirit core."

"May I show myself, Tiamat?"

Taigong Wang said loudly.

The surrounding heroic spirits were greatly alarmed.

"Didn't we already defeat Tiamat?" Hachiman Hikigaya was startled.

“This is the Mother Goddess of Creation who never suppressed herself.” Taigong Wang chuckled. “Even though she fell into beast form, was split in two by the world’s consciousness, and was eventually defeated by us, with the tenacity of a god, some remnants or clones can still survive.”

Even Tiamat, who sealed herself away in the original work, was able to leave behind a phantom image to say goodbye to Fujimaru Ritsuka, and even sent her juvenile form to help Chaldea in a parallel world. Not to mention the Tiamat in her complete form now, she will only become stronger.

Of course, even if something were to remain, it would only be remnants, with its strength reduced to a fraction of its former glory and most of its power gone.

With the firepower of the heroic spirits present, they could easily destroy Tiamat.

"You surrendered so easily because you've already realized one thing, haven't you?"

"...Yes, even humans from distant other worlds are my children."

Accompanied by an ethereal and gentle voice, Tiamat appeared in human form.

She looked slightly younger than her age, her slender and perfect body wrapped in a light blue dress, and her appearance was still stunningly beautiful, with starlight reflected in her pink eyes.

"That's why you didn't put up much resistance," Taigong Wang commented earnestly.

Indeed, even Tiamat's physical body, which displays a true size of 7400 km², rarely uses offensive techniques, let alone the part representing Tiamat's soul in front of us, which is quite passive.

"The strategist of the Investiture of the Gods, you are also my child."

Tiamat lowered her eyes, her whole being exuding a gentle yet sorrowful aura: "I have given birth to many lives, and I have been loved by all beings."

“But the children used me as a diving board and left me. I want to love them forever and want them to stay by my side forever.”

"Is all my love... wrong?"

Tiamat's words evoked complex emotions even among the heroic spirits present.

“This is not an answer I should give,” Taiko-no-Wang said, looking at Hikigaya Hachiman.

Hachiman Hikigaya paused, then pursed his lips: "I don't know."

"But the children all love you, but eventually they will be separated from their mother."

“That’s just how humans are,” Hachiman Hikigaya scratched his head. “Although I’ve always disliked them… no one can stay with anyone forever.”

"It's always too far away for humans; I certainly can't imagine it."

Compared to the gods, humans have only a short lifespan, yet their lives are so dazzling that they attract the attention of the gods.

However, compared to eternal life, sometimes being human is perhaps the most important thing.

"That's right, Tiamat. As a mother, you should hold your head high and say goodbye to your children. What you leave behind is not sadness, but blessings."

Taigong Wang stared straight at Tiamat: "You should still have the ability to rule Lahem, right? Do you want to continue fighting against the humans of this world?"

"Even if there are similar legends, it doesn't mean that the children here abandoned you. If you keep arguing, it will only make things look bad."

Tiamat looked up, her pink eyes clear: "I don't know."

“I have nowhere to go, and so do the children.”

As a god who was abandoned and existed in the imaginary space for a long time, Tiamat did not want to go back, but there was no place for her on Earth either.

"So, would you like to hear my opinion?"

Taigong Wang said with a smile.
