Outside the mirror world, Rin and Luvia closed their eyes and folded their arms, waiting quietly.
Bazett remained in place, unmoving.
Miyu looked at the place where Wu Ming had disappeared with worry.
And Illya...
"Ahhhh! Why hasn't Onii-chan come out yet." Illya kept walking and started complaining.
Kuro, who was sitting on the entrance steps, glanced at Illya with disdain.
"The enemy is a Servant who has been absorbing magic power from the leyline for almost two months. Even if it was Onii-chan, it would be a little troublesome."
Then, Kuro smiled and waved his hand.
"However, with Onii-chan strength, it can definitely be solved."
"However, I am very worried, and I can't help it." Illya said with a drooping head, somewhat disappointed.
"It's okay, Illya is worried Onii-chan, and you don't have to be embarrassed about it." Miyu, who initially saw where Wu Ming had disappeared to, walked towards Illya and touched Illya little head.
"Eh?!" It seems Illya hasn't gotten used to Miyu much, and for a while, she doesn't seem to be able to adapt.
"What is it? Illya, am I exaggerating?" Miyu looked worried.
"That's not the case, it's just that I'm a little uncomfortable. After all, Miyu feels very proficient in her technique." Illya smiled and touched his head.
"This… this is because… Onii-chan often touches my head at home, and I learned about it before I knew it." Miyu said shyly with her cheeks blushing.
"Eh?! Can Miyu enjoy the touch of Onii-chan head every day, I'm so jealous…"
After Illya heard it, she said enviously.
"Illya, don't be like this, I'm embarrassed…" Miyu pushed Illya away with a blush on her face.
And just as Illya was about to say something, suddenly the space shattered.
"Cracked!" A crimson storm gushed out frantically from the shattered space.
"Eh!? What's this?" Illya asked surprised.
Immediately after, a dark face appeared in the shattered space.
"Ah! This… what is this!" Illya was clearly surprised.
"Illya! Miyu! Hurry back!" shouted Rin.
"She's not something you can handle!" Luvia immediately shouted.
But Bazett took the lead in a rush.
Miyu stared blankly at the black Gilgamesh not far away, and fell into chaotic silence.
Miyu clearly knew that this enemy was Wu Ming opponent in the Mirror World. Now that the enemy had pierced through space and emerged from it, then, for Wu Ming, had it been...
"Onii-chan..."
"Aaaah!" Bazett raised his fist, and the rune on his fist appeared. The reinforced fist was hit hard by Bazett into the black Gilgamesh face, but...
"Bang--!" Bazett was knocked out with a bang.
"Hehehehe--!" The black Gilgamesh smiled distortedly, and a dense black magic mist surrounded him.
"High-density magic mist!" Bazett said in surprise.
"This scale is much bigger than Saber!" Rin and Luvia were also surprised.
"Illya, go!" Miyu who was awakened by Bazett attack, immediately pulled Illya towards Rin and Luvia.
"Illya, you take me, Miyu take Luvia, we quickly withdraw from here." Rin said, "But, Onii-chan…"
"Crack!"
"Aaaaaa--!"
The space shattered into an escape that allowed the black Gilgamesh to pass, and she laughed.
"Shoo-bang! Boom!" A black arrow hit black Gilgamesh, and the explosion covered the black Gilgamesh figure.
"Kuro!" Illya looked at Kuro.
"What are you doing! Quickly retreat!" Kuro continued to hold the bow and arrow position, and re-projected the bow and arrow.
"But, Onii-chan, he's still…" said Illya worriedly.
"Onii-chan is very strong, he will definitely be fine, but we, if Onii-chan comes out of the mirror world and finds out that we are all dead, then Onii-chan will be very sad!"
"Illya, let's back off!" At this time, Miyu voice also came from Illya.
"Why?" Illya didn't understand why Miyu had to choose to retreat, and gave up on Wu Ming.
"I have an appointment with Onii-chan. Onii-chan said that he would return safely from the mirror world. I trust Onii-chan."
Seeing Miyu firm gaze, Illya fell silent, then smiled and nodded heavily.
"Un, I see, let's go, Ruby!"
"I worked hard!"
"Shoo! Boom!" Kuro shot the black Gilgamesh with another arrow.
"Aaaaaaaaah"
"Come here, I will give you protection." Kuro, who was already at the entrance, naturally didn't need to take the lead, so she had to protect the others.
Immediately after, Illya hugged Rin and Miyu hugged Luvia, and the two flew to the entrance of the hall.
But Bazett, who originally wanted to continue his attack, started to retreat because Rin said, "The opponent has a Noble Phantasm that can penetrate space. If you want to kill yourself, we won't stop you."
After that Bazett also withdrew.
"Shoohoo!" Kuro shot a few more arrows at the black Gilgamesh.
"Bang! Boom!" However, the magic mist surrounding the black Gilgamesh destroyed Kuro arrow.
"Aaaaaa!"
"Aaaaaaaaaa!"
"Kuro, hurry up!" Illya and the others had already arrived in the middle of the passage, so they quickly summoned Kuro, who was still against the black Gilgamesh and was protecting everyone, to retreat.
Kuro jumped up and grabbed the banister in the hallway.
"Boom boom boom boom!" Countless Noble Phantasms that had lost their target bombarded the supporting framework of the walls and ceilings, and the ceiling began to wobble.
"Bum—Bum—"
"Not yet, Onii-chan hasn't come out yet!" Illya shouted when she saw the underground cave that had started to crumble.
"Too late. The cave collapse can only delay the black Servant steps. We must leave the passage immediately and head back outside, otherwise it is very possible that we will be trapped in this passage." Rin said calmly.
Illya and the others, who were no longer chatty, looked at each other, nodded, and started flying towards the ground.
At this moment, a sound like a plane taking off came from the ground.
