Chapter Ten: Magical Girl Illya Makes Her Dazzling Debut / Chapter Eleven: The Holy Grail Q&A? Let's Make It a Dinner Party!

At Einzbern Castle, Kiritsugu and Kayneth engaged in a life-or-death duel. Both fought with cunning and skill, neither able to gain the upper hand.

In the end, Kiritsugu relied on an Origin Bullet to severely wound Kayneth. Kayneth used a Command Spell to summon Diarmuid, who carried him away.

Emiya carried out an ambush in the Demon Forest as planned, but Gilles de Rais, now on guard, did not let Emiya succeed. The two sides entered a drawn-out battle.

In the end, Gilles de Rais sensed his Master's death and retreated unwillingly.

Emiya knew Yuxian had already succeeded, so he did not pursue him and returned to the Matou Family to meet up with Yuxian.

Without a Master, Gilles de Rais could only remain for a few hours at most, unless he found a new Master to form a contract with. But he had already been listed as a public enemy by the Church, and no Master would be willing to forge another contract with him.

When Emiya returned, he found Yuxian sprawled imperiously across the sofa. He breathed a sigh of relief, knowing that Caster would become the first Servant to leave the stage tonight.

At that moment, Illya walked into the living room in adorable rabbit pajamas, rubbing her bleary eyes.

Puffing out her cheeks, she complained unhappily, "You're all so noisy every night. I'm going to get dark circles under my eyes."

Yuxian and the other two looked at one another, their expressions turning awkward. They truly had not kept the noise down, thinking that a residence as spacious as the Matou Family home would not disturb the three children's rest.

The only thing they had failed to consider was that Illya was not an ordinary child. She was a Magical Girl, and her senses were far sharper than Sakura Matou's and Shinji's.

Yuxian walked over and crouched before Illya, sincerely admitting his mistake as he comforted her. "It was our fault. To make it up to you, how about I take you to the amusement park this weekend?"

"Then it's settled!" The moment Illya heard that Yuxian would take her to the amusement park, she immediately brightened up and skipped away.

The rabbit ears on her pajamas bobbed along with her movements, looking utterly adorable.

After returning to her room, Illya lay in bed, too excited to fall asleep.

She took out the Ruby Wand and held it horizontally before her eyes. "Ruby, what do you think I should wear when I go to the amusement park with Master?"

Ruby: Magical Girl attire.

"No, no. There'll be lots of people at the amusement park. I should wear casual clothes."

Ruby: Then wear the rabbit pajamas. I noticed Master seemed to really like the way you looked in them just now. His eyes were practically glued to you.

"Ruby, I'm angry!"

Bang! Bang! Bang!

Illya puffed out her cheeks, swung the Ruby Wand, and violently smashed it against the edge of the bed.

Ruby: I was wrong, I was wrong! Stop it already! I'm going to break!

"It'd be better if you broke! I've had enough of your terrible personality!" Illya did not stop swinging. She was furious that Ruby had just made a joke involving Master.

Ruby: Ah—I've got it, I've got it! Wear that pink dress.

Hearing that, Illya stopped smashing Ruby and asked uncertainly, "Really?"

Ruby: Really, really! That dress suits Illya best!

Illya thought about it and accepted Ruby's suggestion. "Fine, I'll let you off this time."

Ruby breathed a sigh of relief.

Suddenly, an enormous surge of magical energy appeared.

Ruby: Illya!

"Mm, what disgusting magical energy."

Ruby: It's someone evil. Be careful.

"Ah!" Illya let out a cry, rolled off the bed, tossed aside the Ruby Wand, and ran to rummage through her wardrobe.

Ruby: Illya, what are you doing?

"It must be Master's enemy. I'm going to help Master." As she spoke, Illya rapidly searched through the wardrobe.

The Matou Family was quite wealthy. As long as Illya liked a style of clothing, Emiya would never be stingy. The wardrobe was packed full of clothes Emiya had bought for Illya over the past year.

"Found it."

Illya pulled a pink dress from the wardrobe—the very one Ruby had just suggested.

She quickly put it on and dashed outside.

Ruby: Illya, where are you going?

Illya suddenly ran back, picked up the Ruby Wand, and said, "I almost forgot. Without Ruby, I can't transform into a Magical Girl."

Ruby: You can't go out. Master won't agree to it.

"Ruby, why are you so dumb? We can just secretly follow Master without letting him know."

Ruby: That still won't do!

Illya's tone changed as she said softly, "We'll secretly follow him. If Master doesn't run into danger, we'll quietly come back and go to sleep. We'll just pretend nothing happened. No one will know."

Ruby was about to object again when Illya raised it and threatened, "This won't do, that won't do. I really am going to smash you to pieces. You're useless anyway!"

Ruby: ...

On the other side, sensing that enormous magical energy, Yuxian and the other two swiftly rushed toward its source.

Yuxian was furious. He had killed Ryunosuke in advance, yet Gilles de Rais had still summoned the Sea Monster.

By the time Yuxian arrived at the Miyou River, Artoria and Irisviel, along with the King of Conquerors and Waver, had already arrived ahead of him.

Sola and Diarmuid appeared soon after. Since Kayneth had been severely wounded by the Origin Bullet and was bedridden, Sola had become Diarmuid's new Master.

Golden Flash sat atop Vimana, flying high in the sky as he looked down over the entire Miyou River.

The enormous Sea Monster had appeared in the Miyou River, becoming everyone's enemy. If it could not be destroyed, the disaster it caused would be impossible to predict.

Artoria took the lead. Blessed by the Lady of the Lake, she ran freely across the water as though walking on solid ground.

The King of Conquerors possessed the Noble Phantasm Ionioi Hetairoi and could fly through the sky. He charged forward and cut apart the Sea Monster's tentacles.

Yuxian knew such attacks would be useless against the Sea Monster. He asked Emiya, "Can your Imaginary Numbers Collapse injure its core, the Tome of the Sea God?"

Emiya shook his head. He lacked the strength. The power of Imaginary Numbers Collapse was limited, and it could not penetrate the Sea Monster's massive body to reach its core, unless he was willing to pay the price to project a divine construct, such as Excalibur.

Yuxian frowned and thought to himself. It looked like he could only have Artoria use Excalibur.

He glanced at Diarmuid beside him. The upright knight was closely watching the battle in the Miyou River.

If he told Diarmuid the truth, Diarmuid would not refuse to break Gae Bulg. Yuxian decided to leave that dirty work to Kiritsugu.

At the same time, Kariya once again went after Tokiomi like a mad dog. Lancelot turned the Self-Defense Force fighter jets sent to investigate into Noble Phantasms, staging an aerial battle with Golden Flash in the sky.

Yuxian had no interest in dealing with those two. He let them play by themselves off to the side.

With the Tome of the Sea God supplying it with magical energy, the Sea Monster continuously regenerated. The wounds inflicted on it were completely useless and healed again in an instant.

Magical Girl Illya's Dazzling Entrance

Just as everyone was at a loss, a small figure appeared in midair.

She had long silver-white hair, red eyes, a pink dress, a pair of shimmering Wings of Light behind her, and a short Jewel Staff in her hand.

"Magical Girl Illyasviel von Einzbern has arrived! In the name of the moon, I will destroy you!"

Illya pointed toward the Sea Monster, her voice full of confidence.

Ruby: Illya, that doesn't sound like a Magical Girl line.

"Is that so?" Illya blinked in confusion, and the imposing aura from her entrance vanished without a trace. "They're all the same, hehehe."

Illya's appearance drew everyone's attention, especially when she mentioned the surname Einzbern. It was impossible not to make connections.

Irisviel covered her mouth with both hands, staring at Illya in disbelief.

Yuxian was extremely surprised by Illya's appearance. He was angry, and his tone became stern. "Illya, get down here!"

"No! Illya is a Magical Girl. I can help Master too." For once, Illya did not obediently listen to Yuxian.

Her tone was resolute. "Illya will defeat this ugly, disgusting thing!"

Yuxian saw that Illya would not listen and was about to speak again when Mash stopped him. "Senpai, Illya is serious. As your Servant, she also wants to fight for you."

Yuxian was deeply resistant to letting a child like Illya take part in battle, but when he saw the determined expression on her little face, he simply could not bear to disappoint her goodwill.

Yuxian closed his eyes briefly, then suddenly opened them. "Emiya, use your Hawkeye to point Illya in the right direction. You must aim directly at the Tome of the Sea God. There cannot be the slightest deviation!"

"Yes, Master."

Emiya drew his bow and nocked an arrow. A conical spiral sword appeared on the bowstring, its twisted blade looking exceptionally strange.

This was the Fake Spiral Sword he had created with Projection Magic, an imitation of Caladbolg, the famous sword wielded by Fergus mac Róich, the hero of the Ulster Cycle in Celtic mythology. Legend said that the sword had been forged by fairies of the Land of the Gods and contained the mighty power of divine lightning.

Emiya's hands were steady without the slightest tremor. His gaze was sharp as it pierced through the thick mist over the Miyou River, aiming the sword's tip directly at the Sea Monster's core.

Whoosh!

The spiral sword struck the Sea Monster at a speed too fast for the naked eye to distinguish, blasting a massive hole through its body.

"Now! Illyasviel von Einzbern, use your Noble Phantasm to bombard the place Emiya indicated!" Yuxian raised his right hand, and the Command Spells on the back of it immediately lit up.

Command Spell: Enhancement!

Since he had made the decision, he had to go all out. Failure was not an option.

"Yes, Master."

Illya focused with all her might, gathering the power within her body.

Ruby: Muscular system, nervous system, vascular system, lymphatic system, pseudo-magical circuit conversion... complete!

The moment Ruby finished speaking, Illya shot into the sky. She raised her wand with both hands and swung it forward with all her strength.

"This is everything I have..."

Prisma Cadenza!

Starlight burst forth from Illya's body, shining brilliantly across the entire night sky.

Her immense magical energy transformed into a colossal torrent of starlight, sweeping through the air like a comet and crashing toward the Sea Monster like an overturned galaxy.

Everyone was stunned. At that moment, they all stopped what they were doing. No matter what, they could not have imagined that such terrifying power lay within Illya's tiny body.

Even Golden Flash had no choice but to take her seriously. Though he had absolute confidence in his Enuma Elish, the power before him was too great to ignore.

The power of Illya's Noble Phantasm, Prisma Cadenza, rivaled Golden Flash's Enuma Elish. Coupled with Yuxian's Command Spell enhancement, the Tome of the Sea God within the Sea Monster was instantly annihilated.

However, this power, gained by converting all the systems in her body into pseudo-magical circuits, placed an overwhelming burden on Illya. That was why Yuxian had not wanted her to use her Noble Phantasm.

"Yay..." Seeing that she had successfully destroyed the Sea Monster, Illya weakly made a victory sign. Then her whole body swayed. Unable to keep the Wings of Light behind her back intact, she fell from the sky.

Emiya took a quick step forward and caught her, preventing her from hitting the ground and suffering further injury.

Irisviel hurried over as well and asked worriedly, "Is she... all right?"

Hearing Irisviel's voice, Illya mumbled drowsily, "Huh! I think I heard Mom's voice. Did I hear wrong?"

Seeing Illya in such poor condition, Yuxian grew anxious and immediately used a Command Spell on her.

Command Spell: Recovery.

Illya's weakness improved slightly, but the effect was far from ideal.

This weakness was caused more by the burden on her own body than by external injuries. Yuxian's Level 1 Command Spell recovery had limited effect. Illya needed time to slowly recover on her own.

Faced with this situation, Yuxian had no desire to remain any longer. He said, "I'll leave the rest to you."

"King of Conquerors Iskandar, how can I lose to a child! Come, King of Knights. Let's see who destroys more Sea Monsters." The King of Conquerors drove Ionioi Hetairoi into the Miyou River with a laugh, dealing with the remaining Sea Monsters.

"Gladly!" Artoria answered, running across the river while swinging her sword and cutting down every Sea Monster she encountered.

The remaining Sea Monsters were quickly cleared away.

Caster officially became the first Servant to leave this Holy Grail War.

A Banquet Instead of the Holy Grail Debate!

Yuxian and the others returned to the Matou Family home, placed Illya on the bed, and Mash voluntarily stayed behind to take care of her.
