After learning the truth of the Holy Grail War, the final battle could commence.
Declaring that everyone could now fight according to their own will, in Ryuya's view, among the Fourth Holy Grail War's Servants, aside from the big-eyed Gilles, the berserk Lancelot who had lost his reason, and Hassan who obeyed his master's commands, the remaining four Servants each possessed their own unique charm.
Iskandar, who believed in the path of conquest, forthright and bright.
Gilgamesh, the King of Heroes, criticized by many and outrageously proud, but who, even when corrupted by the All the World's Evils in the original work, maintained his self, even declaring, "The King acknowledges, the King permits, the King bears the weight of the entire world!"
Diarmuid, with Luck E, exceptional spearmanship, adhering to chivalry, loyal to his lord.
Artoria Pendragon, reflecting on the past, though denying her own Kingly path, still progressing.
Stating they could all do as they wished, because the Holy Grail War was about to end… that was Ryuya's answer.
"I see. Then this king's intention needs no further explanation, right?"
Drawing Ea without ceremony, watching Enkidu and Female Gil's blissful expressions, Golden Gil laughed.
"This king wishes to test just how strong the man is who could conquer both the female version of this king and Enkidu!"
Where he fell, he would rise again.
Expressing his desire to challenge Ryuya once more, Golden Gil stated.
"Mmm... This king feels the same."
Looking conflictedly at Golden Gil, Iskandar needed no further words.
Since the Holy Grail War was ending, before returning to the Throne of Heroes, he also wanted to challenge the strongest.
"I am willing to follow my Lord's command, but if possible..."
His twin spears gleaming, no need to say more… this was Diarmuid.
As for Saber, she seemed to only want to chat with Morgan, Merlin, and her other-world self, having no particular desire for battle.
"Saber, I thank you for your assistance these past days. But as things stand, there's no further meaning in my continued existence here."
From Kiritsugu's perspective, with his strong sense of justice and clear goal of winning the Holy Grail War, now that the war held no meaning, he naturally had no reason to stay.
Nodding, he left the Einzbern Castle, returning to Snowfield City with a sigh, feeling he was about to embark on his lonely path once again.
"Diarmuid, your wish... forget it."
The competition to prove his genius had also lost meaning, but the pride of a genius made Kayneth unwilling to give up or stop.
Expressing a desire to test Ryuya's strength, he wanted to know the gap between himself and a true powerhouse.
"Rider, by the power of my Command Spell, I command you… achieve victory!"
"King of Conqueror, by the power of my Command Spell, I command you… achieve victory!"
"Alexander the Great, I, Waver Velvet, petition the King in my name! Conquer the entire world! Absolutely do not allow failure!"
His time with Iskandar hadn't been long, but Waver, with his excellent compatibility, had a truly great relationship with the King of Conquerors. He had even taken Iskandar to the library, bought him T-shirts, and shared feasts.
Recalling every moment spent with Iskandar, Waver had never felt so happy.
The King's companionship had evolved his courage, and even facing his mentor Kayneth again, he wouldn't retreat half a step.
But as a third-rate Master, what right did he have to campaign with Iskandar?
Thinking himself a burden, just as he was about to leave like Kiritsugu...
"Master."
Looking at the tearful Waver, Iskandar laughed heartily, grabbing Waver and placing him on his chariot. He asked loudly, "Waver!"
"Ah... Yes!"
A bit startled by Iskandar's sudden volume, Waver was somewhat afraid.
"You, are you willing to become this king's subject?"
"I..."
Staring in surprise at Iskandar, Waver never expected Rider would ask him that.
No need for hesitation or doubt, the passionate youth gave his answer immediately.
"Willing! I am willing!"
"You are my only King! Please let me follow in your footsteps! Let me advance towards our shared ideal!"
Hearing Waver's reply, Iskandar was extremely pleased.
"Hahaha! In that case, this king shall take the lead first!"
Raising his sword to point at Ryuya, Iskandar laughed loudly, "Ryuya! This king challenges you!"
"Granted."
Nodding, Ryuya snapped his fingers.
The scenery of the Einzbern Castle rapidly shifted, and everyone found themselves inside the Rashomon.
"Come. I've granted you a battlefield."
"Good! In that case, this king will go all out!"
"Ionioi Hetairoi!"
The blade in his hand, known as the Distant Trampling Domination, radiated powerful magical energy.
With the assistance of Waver's three Command Spells, Iskandar achieved his peak condition.
Directly using his ultimate technique, he invoked his long-held Reality Marble, the Ionian Hetairoi.
"This place is..."
Under the scorching sun, everyone was pulled into Iskandar's Reality Marble.
Seeing the tens of thousands of soldiers suddenly appear, everyone noticed these weren't mere illusory spirits but genuine Heroic Spirits.
"This... how is this possible?"
Shocked that Iskandar could summon tens of thousands of Heroic Spirits, those seeing this for the first time were utterly amazed.
Although these Spirits weren't individually strong, their military formation, coordination, and aura were absolutely unmatched.
Feeling as if they were witnessing the King of Conquerors' army, the unstoppable Macedonian forces, girls like the Yukinoshita Sisters and Kaguya, who weren't fully aware of Ryuya's strength, grew tense.
"Relax, Yukinoshita. If it's about numbers, Ryu won't lose to anyone."
Smiling at the army-leading Iskandar, Female Gil didn't believe for a second her lover would lose. After all...
"A plain of dancing hot sand. Is this the land you once conquered, King of Conquerors?"
"Since it's an army confrontation, it wouldn't be right for me to annihilate you here with individual strength alone."
Although he could single-handedly charge into Iskandar's army and sweep through them like playing a musou game, since the King of Conquerors chose an army battle, Ryuya felt it only proper to summon his own forces.
"Sun God, Uruk Heroic Spirit Monument!"
"Sun-Crowned King! Sun-Crowned King!"
Those who sing the King's name are the King's subjects!
As even more astounding roars erupted, everyone present witnessed a scene that made them tremble.
"Charge forward! No retreat!"
"Determination to break the enemy lines! No survival without victory!"
Amidst countless battle cries, before the Sun-Crowned King, the soldiers of Camelot and the Hundred Races of Uruk all followed their King's footsteps.
Even the chieftains of the various non-human races, each possessing strength rivaling third-generation deities like Ishtar and Ereshkigal, manifested one by one.
That was the power of the King of Myriad Races.
"Remember the will! The Sun is eternal!"
If Iskandar's army consisted of Heroic Spirits averaging ranks D and C, then Ryuya's warriors comprised a myriad army ranging from the weakest D-rank Camelot knights to S-rank non-human chieftains.
They all assumed their formations. Although the soldiers from Camelot and Uruk had never cooperated before, the saying held true...
Those who sing the King's name are the King's subjects!
Standing behind Ryuya, facing Iskandar with an absolutely overwhelming presence… King against King, army against army. This was the bond and conviction between them.
Thus, this was Ryuya, the Sun-Crowned King.
