Did the Heroic Spirit I conquered become a reality?

The last rays of the setting sun spilled onto the wide surface of the Euphrates River, bathing the entire city of Uruk in a warm and tranquil glow.

The two sat by the river watching the sunset. Tiamat did not speak to Tohsaka Yu again, but instead reminisced about the day's events, as if she were pondering something deeper.

"Did you not have fun today?" Yu Tohsaka couldn't help but ask.

Tiamat gently shook her head, took out her small notebook and pencil, and slowly wrote on it:

"The human world... is noisy, bright, and also... fragile."

The handwriting was still somewhat immature, but the meaning it contained made Tohsaka Yu's heart tighten.

She saw the beauty and vitality of life, but also felt its brevity and transience. Compared to her own almost eternal existence, human life is brilliant yet fleeting.

"I'm very happy to be with Yu."

She wrote that, and then drew a small smiley face.

"But..." She paused for a long time, the pen tip hovering over the paper, before finally writing, "This place... seems not to belong to me."

As expected… Tohsaka Yu sighed softly in his heart.

Even if he tried his best to accompany her and even create the illusion of being "popular", and even if Gilgamesh cooperated in secret, the sense of alienation that originated from the essence of existence could not be easily erased.

Tiamat felt warmth, but also became more clearly aware of her "difference" from the world.

She is Tiamat, the mother goddess of creation, but also the Beast who brings about the end.

Today, all these "children" who know her identity are afraid of her... but this is actually only natural.

Even though she forced a smile, she could still faintly sense the fear and rejection that came from the depths of her soul.

Like an outsider who has stumbled into a warm human world, even though she is embraced by the sun, the loneliness etched into the essence of her existence, and the invisible barrier between her and this world, still haunt her.

Tiamat would look at her blurry reflection in the river—a beautiful, horned, inhuman reflection—and her eyes would become somewhat lost and bewildered.

She would subconsciously tighten her grip on Tohsaka Yu's hand, as if only by grasping this sole connection could she prove that she was not in an illusion.

Yu Tohsaka turned his head to look at her beautiful profile, which showed a slight hint of disappointment, and his eyes softened.

He didn't offer any empty words of comfort like "You belong here," but simply reached out and gently put his arm around her shoulder, pulling her into his embrace.

Tiamat paused slightly, her body stiffening for a moment, but she quickly relaxed, obediently burying her head deeper into his neck like a kitten seeking shelter.

Although she is the creator goddess, at this moment she is like a child, and her unique fragrance, like that of the primordial ocean, lingers around Tohsaka Yu's nose.

“It’s alright,” Yu Tohsaka said softly, her voice gentle yet firm. “Whether I belong here or not is not important. What is important is… that I am here now, and you are here too.”

He paused, then continued, "I will stay with you until we find a place... where you can truly feel at ease."

Tiamat didn't respond, but let out a very soft "Aaaa..." from her throat, filled with satisfaction and dependence, and then reached out and hugged his waist tightly.

The two sat quietly on the riverbank, embracing each other, watching the last rays of the sunset disappear completely below the horizon.

"Shall we...go back?"

After a long while, Tohsaka Yu asked softly.

As the night air grew cooler, he worried that Tiamat's spirit might feel uncomfortable from being exposed to the elements for an extended period.

Tiamat gave a soft "hmm," and seemed somewhat reluctant to lift her head from his embrace, but still obediently nodded.

……

The night is as deep as ink.

The two unknowingly returned to the palace, where the warm lights and calming incense dispelled the chill of the night.

Yuu Tohsaka could clearly sense that Tiamat seemed to be a little tired as well.

That's normal. For someone accustomed to the unchanging environment of the imaginary space or the Sea of ​​Origin, receiving a whole day's worth of complex and vibrant information from the human world would probably be mentally taxing, even for her.

"Are you tired?" Yu Tohsaka asked softly.

Tiamat looked up at him, a hint of weariness in her ruby ​​eyes, but she still shook her head slightly and wrote in her notebook: "Today... I'm very happy."

Despite being happy, the sense of loss from not fitting in didn't completely disappear.

Seeing the undisguised vulnerability in her eyes, Tohsaka Yu's heart softened. He didn't say anything more, but simply reached out and gently hugged her, then buried his face in her chest.

Tiamat seemed to want to feel his warmth more intimately, so she reached out and hugged the boy back tightly.

His soft body pressed tightly against Tohsaka Yu's, and even through the thin fabric of her clothes, he could still feel the grandeur of her heart.

Although she already knew that she was big, this was still a bit too exaggerated... Even though she had a clear understanding of Tiamat, Tohsaka Yu was still incredibly 'shocked' when she felt this amazing fullness.

He instinctively tightened his arms, holding Tiamat even closer.

Faintly, one could smell a faint fragrance in the nasal cavity, like the milk that Tohsaka Yu had drunk in the real world in the past, mixed with an enticing sweetness.

Yu Tohsaka was a very self-disciplined person when she was at the Clock Tower. She went to bed early and got up early every day. Before going to bed at night, she would take a hot bath and drink a cup of hot milk before she could fall asleep.

But ever since he transmigrated to this world, he hasn't had a proper night's sleep... he hasn't even had a glass of milk.

Although having Tiamat by her side now allows her to get a good night's sleep, it would be even more perfect if she could take a hot bath and drink a glass of milk... Yu Tohsaka sighed inwardly.

Seemingly sensing something, Tiamat tilted her head in confusion and wrote a note in her notebook.

"Are you homesick again?"

Yu Tohsaka paused for a moment, then smiled and shook his head: "No, I was just thinking that my magic circuits seem to have room for 'upgrading,' but I don't know how to do it."

Tiamat was taken aback, but a hint of tenderness quickly appeared in her eyes.

She wrote something in her notebook and then handed it to Yu Tohsaka.

Almost instantly upon seeing these words, Tohsaka Yu's eyes widened in disbelief, and she instinctively looked up: "Are you serious?"

Tiamat nodded slightly.

She gently placed one hand on her full, firm breasts, her eyes softening: "It may be a little embarrassing for you... but it's the only way."

"Would you...hate it?"

When she wrote those words, her expression suddenly seemed a little uneasy.

"It's not that I would hate it... I'm just worried that you would hate it."

As Yu Tohsaka spoke, she suddenly became somewhat helpless.

Although he had long known that when someone wanted to give 'magic' to another, they would usually do so in a very primitive way... he still didn't expect that there would actually be such a method.

Although it's not quite appropriate, if I just take a small bite... it should be fine, right?

Without further hesitation, Yu Tohsaka silently lowered her head and buried herself in Tiamat's arms.

At the same time, a sweet magical power quietly flowed into Tiamat's body.

Volume 1: Chapter 23 Magic Circuit EX

The warm, soft touch pressed tightly against her cheek, carrying a faint, ethereal fragrance like the ocean at the dawn of life, and an indescribable sweet magic, continuously flowing into Tohsaka Yu's body.

This is an unprecedented experience.

Unlike the shock and transformation she experienced when passively receiving Tiamat's magical gift for the first time, this time, it was Tohsaka Yu who actively sought it out, and it was Tiamat who gently gave it to her.

That vast, ocean-like magic silently nourished Yu Tohsaka, as well as the magic circuit within him that was already marked with the "Tiamat" brand.

He could clearly sense that his magic circuits were undergoing a more profound and fundamental change than before.

After an unknown amount of time, as the sweet flow of magic gradually subsided, Yu Tohsaka felt an unprecedented surge of power coursing through his body, and only then did he reluctantly leave her embrace.

"Hiccup~"

He let out a satisfied burp, then looked up to see Tiamat's beautiful face, slightly flushed, and her ruby ​​eyes, which seemed brighter than usual and had a moist sheen.

She seemed a little uncomfortable with the direct and primitive way the magic was transferred just now; her eyes darted away slightly, but more than anything, they showed a gentle concern.

“Aaa…” she murmured, her meaning unclear, as if checking on Tohsaka Yu’s condition.

Before he could respond, the familiar pale blue light screen reappeared before Yu Tohsaka's eyes.

[Warning: Deep synchronization of the host's magic circuits with Beast II detected...]

[Homology enhancement...secondary optimization of loop structure...complete.]

[Congratulations, host! Your magic circuit has been upgraded to [Magic Circuit - Tiamat Version Ver. 2.0], significantly improving circuit resilience and magic transmission efficiency.]

Next, the personal attribute panel expands:

【Name: Tohsaka Yu】

【Strength: E】

[Durability: D+] (Slight improvement)

【Agility D】

[Magic: EX] (Significantly enhanced!)

[Lucky: B]

[Territory Construction: C]

[Props made: C]

[Possessing skills]

[Divinity (Sign of Tiamat): E]

Note: Due to the establishment of a deeper soul link with the Mother Goddess of Creation, divine qualities are slightly enhanced, resistance to divine attacks is increased, and one is more easily perceived by divine beings, which may trigger their special attention (threat or closeness).

【Gem Magic: B】

Note: This is a family heirloom magic technique of the Tohsaka family, demonstrating high talent and skill in storing and releasing magical power using gems.

[High-speed chanting: D]

Explanation: The ability to shorten the magic chanting time of Jiulin (six)?俬溜〕Qi Er〆〦Shrimp, the learning results of the Clock Tower.

【The Primordial Sea's Favor: A+】

Note: Blessed and connected with Tiamat, the Mother Goddess of Creation, her magic recovery speed is greatly enhanced, and she possesses extremely high resistance to mental interference and divine oppression. She can also draw upon the power of the 'Sea of ​​Origin' at a deeper level. (Passive effect: Significantly increases her attractiveness to most older members of the opposite sex, easily triggering their strong protective instincts and maternal instincts.)

[New Skill]

[Whispers of the Sea of ​​Life: D]

Note: It can faintly sense life fluctuations or emotional changes related to Tiamat, and can soothe berserk creatures associated with the "Sea of ​​Origin" to some extent.

【Holding a Noble Phantasm】

【mom--!!!】

Note: This skill consumes a large amount of magic power, summoning Tiamat's spirit. Each use places a significant burden on the magic circuits. (After circuit enhancement, the burden is slightly reduced, and the duration may be extended.)

"Magic...EX?!"

Yu Tohsaka stared at the glaring level, and his eye twitched involuntarily.

Although it was expected, the fact that EX-level magic appeared in a human magician was simply unbelievable!

And the passive effect following [The Favor of the Primordial Sea]... "Significantly increased" wasn't enough, they added "Strong protective instinct and maternal instinct"? Are they afraid they won't be conspicuous enough when they go out in the future?

Feeling the vast and powerful magic within her body, imbued with a rich life force, and savoring the slightly embarrassing yet highly effective "upgrade method" she had just experienced, Tohsaka Yu's expression became incredibly subtle.

Can this really still be considered "magic circuit evolution"?

Rather than an evolution of the circuit, it's more like Tiamat's favorability has increased to an immeasurable level, directly unlocking the next stage of even closer "CG events" and "exclusive passive skills".

Just as Yu Tohsaka was still processing this explosive attribute boost, a new line of text, emitting a faint golden glow, quietly appeared at the bottom of the panel:

[Worldline Observation: Current Singularity "Tiamat Destruction Ending" correction value +0.08%]

[Current probability of survival: 1.23% (an increase of 0.08% from the initial value)]

[Note: Correcting world lines is extremely difficult; even minor changes can trigger huge backlashes or chain reactions. Please act with caution.]

"World line change rate... the probability of survival is still only 1.23%..." Yu Tohsaka looked at the newly added information, quickly calmed down, and his brows furrowed slightly.

Although his deepening relationship with Tiamat did indeed shake her destined fate, the possibility of that happening is still extremely slim...

Ultimately, Tiamat's existence is contrary to human reason. Her instinct to "return" is ingrained in her bones. Even if she is willing to restrain herself, how long can this restraint last?
