The time passed without him noticing.

The screens continued displaying information about the movements of factions that he himself observed or that Minerva summarized for him.

None of them came close to truly bothering him. Since he had prepared countermeasures for many situations that might arise in the future, including the alliance of factions. He could guess that many of them formed an alliance out of fear that Chaldea might make a move against them, so it was more for safety than anything else. But other alliances aimed to antagonize his faction without a doubt; the Old Satan Faction was one of them, and even the Chaos Brigade, which Ophis commanded only in name...

Speaking of which, he still hadn't had the chance to meet Ophis. He thought she would come after him the moment she learned of his strength... I mean, the "fanfics" he read in his first life always portrayed it that way, which was kind of illogical, to be honest... But in a world where the "power of breasts" existed, logic didn't exist, so those authors didn't exaggerate too much, right?

Though that doesn't make much difference now...

He was more concerned with Rizevim Livan Lucifer, who had hidden even from his information network.

Rizevim was the only biological son of the original Lucifer and Lilith, who otherwise used the Book of Lucifer to asexually produce the first generation of Demons. Some time after the Great War, which resulted in the death of all four original Great Satans, he had a son named Razevan. Rizevim became one of the main members of the Old Satan Faction but had no interest in taking his father's position. He was one of the three Super Demons in the Underworld, alongside Sirzechs Gremory and Ajuka Astaroth, from the Anti-Satan Faction.

During the civil war, Rizevim and Razevan hid instead of participating, resulting in the victory of the Anti-Satan Faction. At some point before the series began, he suggested that his son abuse his grandson, Vali, if he feared him, awakening Vali's hatred for both him and his father, and forcing Vali to flee. Later, he killed Razevan for fearing Vali's retaliation.

Since then, Rizevim lived in boredom until Euclid mentioned Ophis, the Holy Grail, the Other World, and the Apocalyptic Beast. All of this sparked his desire to spread absolute chaos. In his twisted mind, the vision was clear: revive the legendary 666, the Beast of the Apocalypse, and with it, crush and destroy the Great Red itself, the one who ruled the skies of the Dimensional Void. But that would only be the beginning.

From there, he would lead an army of Evil Dragons, deformed creatures thirsting for destruction, marching mercilessly beyond the limits of this world. He would invade the Other World, a parallel plane of existence, and there, there would be no mercy. Gods, monsters, heroes, and any being that dared to exist would be annihilated under his tyrannical rule.

In his ideal utopia, there would be no room for divinities or traditions. He would be remembered as the great disaster that crossed worlds, the evil being from unknown lands, bringing with him an unprecedented calamity. And on the throne raised over the ashes of two worlds, he would proclaim himself the one and only Great Maou, surpassing even the name of Lucifer etched in history.

That was the delusion that drove him, and the mere idea of realizing it made his body tremble with pleasure.

He was the exact opposite of himself, who believed, with every fiber of his being, that humanity deserved to survive, not as servants of capricious supernatural beings or as fodder for the selfish ambitions of those who were myths in the eyes of "normal humans," but as the true heir of its own destiny. If the heavens decreed the destruction of men, he would cut through the heavens. If dragons threatened the balance, he would slay them. If another world tried to subjugate this one, he would lift it upon his own shoulders and face the impossible.

For him, no divinity or monster was worthy of deciding humanity's future. And even if he was labeled a traitor or insane by men, nothing would sway him from his path. He would be the shield and the spear, the last defender at the end of the world, and he would etch into the stars the name of the one who dared to protect humanity until his last breath.

At first, he thought he had received all that power for free. But over time, he realized it wasn't quite like that. He gave himself a purpose, and for the first time since arriving in this world, he felt he truly had a direction and no longer felt lost.

Saving people, saving humanity...

Just as he had done in his past life, as Ritsuka Fujimaru... That was how his first life would truly make sense. That all the path up to that point would be worth it...

Besides, he wasn't a human supremacist. He never was. Nor was he xenophobic toward other races.

If he were, he would have already taken drastic measures to eradicate all supernatural species from this world, something he could do if he wanted. But that kind of action would destroy the most important foundation of everything he had built: the respect of his Servants.

And that... that was something he would never put at risk.

It would be a betrayal of Chaldea's ideals.

It would be completely out of line with his alignment as the Last Master of Humanity.

He only wanted humans to have a peaceful life in this world.

Was that too much to ask?

Though it was easy to say he only wanted peace for humans, he knew there was a certain hypocrisy in that.

After all, since arriving in this world, he had already made many questionable decisions. Some... frankly stupid.

For example: what he did with Issei and his two perverted friends. He justified to himself that he had done it to "correct them," to rid them of their perversity and put them on the right path. But deep down, he knew he had no right to decide that for them.

The truth?

It was pure selfishness.

He never liked the three of them. And it was that raw, silent, deeply human selfishness that led him to abandon him. He was talking about Issei.

Fatally wounded, left in a park. And worse: after having his only protection stolen, the only thing that would keep him alive in this world.

In the end, he was still human.

And humans... are not perfect.

No matter how much power he had accumulated, no matter the titles and achievements he carried, he still made mistakes. He was still driven by petty impulses, thoughtless decisions, and above all, by the scars of his first life.

If he didn't remember it, if he were just Ritsuka Fujimaru, he would probably be that typical idealistic, naive, and bland hero. A good boy with good intentions, but empty of real depth.

But he wasn't.

But that's beside the point...

Why was he thinking about this after everything...?

Was it because he remembered someone with ideals opposite to his own?

It felt like a broken record, stuck on that thought now. His ambitions were already clear through his actions; reflecting on them was a waste of time...

Back to the heart of the matter.

Due to their differing ambitions, he and Rizevim would clash sooner or later, and for that reason, he needed to prepare properly.

That was why he came here to the "World Observation Room," to try to find him.

Fortunately, he had Valerie Tepes, who was essential to Rizevim's plans. In other words, sooner or later, that "demon" would come after him...

It would be good to find him first, but his information network hadn't found any decent leads, not even about his allies or subordinates... Something that left him slightly disturbed.

He let out a sigh...

His eyes landed on the digital clock in the bottom corner of one of the screens, marking 11:57. He stretched.

It was time to get some fresh air.

"Minerva, I'm heading out. You take care of things here."

The AI blinked at him, her usual sharp smile in place.

"Of course, master. If something explodes, I'll let you know."

"If it explodes, let it..." he muttered, grabbing the black coat slung over the back of the chair and putting it on with a swift motion, then lightly cracking his neck, feeling the joints respond with small, satisfying pops. He turned to the automatic door, which opened silently, and before leaving, gave one last glance at the projection.

Arriving at the elevator, Kazuya pressed the button, and the doors opened with a discreet ding. He stepped inside, leaning against the brushed metal wall.

The elevator began to ascend.

The digital display marked the progress, and Kazuya closed his eyes for a moment, taking a deep breath.

The elevator stopped with a soft click.

The doors opened, revealing a long corridor, softly lit by noon-light lamps.

Kazuya stepped out of the elevator silently and walked down the corridor as the elevator doors disappeared behind the staircase. Upon reaching the room, he found Karna standing by the window.

The Servant was dressed in his simple white garments.

His eyes were turned to the sky, serene as always.

"Taking a sunbath now?" Kazuya commented, his voice tinged with slight irony.

Karna didn't turn, but the faintest hint of a smile appeared on his lips.

"According to Edmond, it's what men do when they have too much time and too many thoughts."

"Makes sense. He probably read that in some 19th-century French book."

Karna turned slowly, his arms still crossed behind his back. His eyes gleamed slightly as they settled on Kazuya, but there was no surprise in them, only that usual calm.

"You look tired, master..." he said, as direct as ever.

Kazuya shrugged. "Sleep is for the weak."

"Or for the living."

"Almost the same thing."

"..."

Kazuya let out a sigh and approached Karna, standing beside him, looking out toward his garden visible through the window.

"...Sorry..."

Karna looked at the young man, confused.

"Apologizing for what, master?"

"Well, I think I've been a terrible friend for not asking how you were feeling with that whole mission I entrusted to you..." Kazuya said, his tone calm, almost regretful. "You and Indra have a history, don't you? Even if the Indra of this world isn't the same as the one from your legend... When you came back with the report, I was so focused on the next steps, on what to do next, that I forgot to ask: how do you feel about all this? About having defeated the father of your greatest rival..."

As he spoke, he couldn't help but think of the living legend beside him.

Son of Kunti, a human princess, and Surya, the god of the Sun, Karna was born before his mother even married King Pandu, patriarch of the Kuru lineage. Kunti possessed a sacred mantra that allowed her to conceive children with gods. Before using this gift to bear Pandu's royal sons, she tested it by invoking Surya... and from him came Karna, already blessed with divine power and clad in golden armor that made his body invulnerable, undeniable proof of his divine origin.

But even with such grace, Kunti rejected him. The existence of that son, illegitimate in the eyes of society, didn't fit the role of a future queen. And so, Karna was abandoned... left on the margins of the world before he could even understand what the world was.

Unaware of who his parents were, Karna grew up among the humble. The boy with a stern demeanor and rough behavior was soon labeled a burden, an inconvenience.

But he never hated anyone for it.

He didn't hate his mother or his fate.

Despite everything, Karna grew up as a virtuous young man, steadfast in his convictions. Perhaps because he was born with such power, he believed he needed to prove the worth of his existence more than anyone else. Living justly was his way of compensating for those who had no power. A self-imposed burden, but one carried with dignity.

As a young man, he attended a conference of the Kuru, where the five Pandava brothers, Kunti's legitimate sons, displayed their martial skills. Arjuna, the third brother, was particularly talented with the bow and arrow. Amid so much praise, Karna stood up, challenging Arjuna as an equal.

But his humble origins weighed against him. Karna was ridiculed for not being of noble blood. To challenge Arjuna, they said, one had to be at least a Kshatriya, and Karna was merely the son of a charioteer... a Vaishya or even a Shudra. Laughter and scorn surrounded him.

Until Duryodhana, prince of the Kaurava, raised his hand in his defense. Fascinated by Karna's strength, he made him a king on the spot, defying the caste system in the name of honor.

Karna was saved from disgrace... but only momentarily.

Karna's adoptive father, upon learning of the appointment, appeared and revealed his simple origins, which only fueled the Pandavas' mockery. One of them even said, "The son of a charioteer should be ashamed."

Karna could endure any insult directed at him. But at the one who raised him? No.

Even if he was a humble, greedy, or ordinary man, he was the father who gave him love. And for Karna, that was worth more than any divine lineage.

That was how the antagonism between Karna and the Pandavas began.

And even as he walked through shadows and conflicts, Karna never betrayed those who extended a hand to him.

Duryodhana treated him with respect and loyalty.

And Karna repaid him with his own life.

But what awaited him beyond his journey of pain and virtue... was a war.

A cruel war.

The inevitable confrontation against the five Pandava brothers, and more specifically, against the legendary hero Arjuna.

The conflict between the Kauravas, to whom Karna swore loyalty, and the Pandavas, led by Arjuna, grew in tension and hatred until it culminated in the Kurukshetra War, a battle that would decide the fate of an entire empire.

On the battlefield, only Arjuna could face Karna as an equal. But even Arjuna knew: facing Karna directly was signing his own death sentence.

Amid intrigues, old wounds, and fulfilled prophecies, the final clash approached.

It was then that Kunti, Karna's true mother, attempted one last, desperate act of redemption. She revealed her secret only to Krishna, the Pandavas' advisor and friend, and together they went to Karna. There, amid tears and regrets, she confessed: she was his mother. That abandoning him was a mistake. That fighting against the Pandavas, his half-brothers, would bring him no glory, only ruin. She begged him to join them, to finally return to the place that was rightfully his.

But it was too late.

Karna understood and refused her plea, promising he would use all his strength only against Arjuna. He escorted Kunti to the gates, thanked her for calling him her son, at least once, and bid her farewell.

Then came the betrayal of the gods.

Knowing Karna would never yield, Indra, the god of thunder and Arjuna's father, took the form of a Brahmin and, disguised, asked for Karna's golden armor, which he had carried since birth. Karna, even knowing what it meant, gave him the armor.

He never refused a request.

And by giving up what made him invulnerable, he sealed his fate.

Moved by Karna's generosity, Indra asked why, and the demigod's response stunned the King of the Gods.

Seeing such nobility, Indra gifted Karna his sacred spear, the most powerful in his arsenal, which had never been granted even to his own son. It was the only way to atone for the dishonor of his deception.

But even with the spear in hand, Karna went to the battlefield bare, unprotected, a shadow of what he had been.

Then came the final battle.

Karna was alone.

His charioteer, bought by the Pandavas, was no longer loyal to him. The brothers he now faced were his blood, and Arjuna... was his mirror.

During the battle, the curse on Karna manifested. The wheel of his chariot sank into the mud, leaving him vulnerable. Arjuna, guided by Krishna, readied his bow and did not hesitate.

The arrow that felled the Sun was fired.

And Karna fell.

They say that after his death, Karna joined his father, the Sun god. And he was remembered not only as the hero in golden armor... but as the hero of generosity.

The one who never refused a request.

The one who chose honor over glory.

The one who, even cursed by gods, brothers, and fate, remained noble until the end.

That was why Karna was his favorite Servant... Who was as badass as him? No one...

He snapped out of his thoughts when Karna sighed lightly and responded to his apologies with his usual calm:

"Master, you don't need to apologize for something so trivial. I feel no satisfaction in having defeated the one who sabotaged me in life... because, in truth, I never hated him. Nor do I feel any different now. He simply gave me a good fight, nothing more..."

"I see..." Kazuya turned his gaze back to the garden and smiled as he said, "You're genuinely a good-hearted person..."

Karna remained silent for a few seconds.

Then, with a firm and serene voice, he replied:

"I'm not good, master. I simply do what I believe is right. Being good or evil... that's for others to decide, not me..."

He turned his face slightly toward the young man, his white hair swaying in the breeze.

"But... if you managed to see something of value in me... then I'm grateful. That's more than many have ever granted me. And even if the world calls me a fool... I won't back down from who I am..."

There was dignity in every syllable, not as if trying to convince, but as someone who simply accepted their own fate, without pride, without shame. Just conviction.

Kazuya looked at him with shining eyes, like someone who had just seen a childhood hero in the flesh.

"Hah... That's why you're my favorite, you know?"

Without ceremony, he gave Karna a light pat on the shoulder.

"Always steadfast, always upright, even when the whole world spits in your face. You don't need to be 'good' in the common sense, Karna. You're you. And that's enough for a lot of people, including me..."

He turned back to the garden, the smile still on his lips.

"Seriously, thanks for being here..."

Karna merely looked at him calmly and replied:

"As long as you walk this path, Kazuya... no matter how many enemies arise, or how many times the world turns against you, I'll be by your side. Not out of blind loyalty, but because I believe in what you carry..."

And, for a brief moment, a small smile appeared on the lips of the hero who rarely smiled.

"After all... even a condemned warrior can find redemption if there's someone who sees value in him..."

Kazuya looked at him, surprised, feeling there was something more in those words. Dream cycle again? A sigh escaped his lips.

"Thanks... But let's stop with the mushy stuff now..."

"..."

"...Do you know where Valerie is?"

"She's probably on the terrace with Edmond..."

"Thanks, then, if you'll excuse me..."

__________________________

(A/N: This chapter was a small moment to bring back a bit of the bond between Kazuya and Karna — not just as Master and Servant, but as friends who share different ideals and scars, yet still walk side by side. It's no secret that Karna is Kazuya's favorite Servant. And honestly… who could blame him?

This was my attempt to do justice to Karna's personality: dignified, honest, resolute — standing firm even when the whole world is against him. The kind of character who never needs to raise his voice to earn respect.

I hope I got the tone right. If you made it this far and felt something watching the two share this moment of mutual respect, then it was already worth it.
