Gudako was having a nightmare.
Maybe the stress of restoring the foundations of humanity was getting to her again.
Maybe it was the absurd number of Black Keys that had appeared instead of the servants she had so desperately hoped would appear.
As Gudako floated through the black void that was her nightmare, she saw a pointy rainbow-colored rock float by. Of course, it was Saint Quartz. The appearance was unmistakable. More and more Saint Quartz appeared till Gudako was literally swimming in them. The moment she reached out and tried to grab one, however, they all turned into Black Keys.
Gudako fell to her knees in despair. Despair as the gacha she desperately rolled never gave her the SSR servant she wanted, only getting spooked by more copies of Kiyohime and Black Keys. Maybe that was the price she paid for having the gall to put Kiyohime into her party and then taking her out as soon as she rolled Heracles.
As she sank into the piles of Black Keys, she saw Gilgamesh float past her. "Fuahahaha! Summoning me means you've used up all of your luck, mongrel!"
Next was Jeanne D'Arc, calmly floating by. "Servant Ruler, Jeanne D'Arc. I'm really glad to meet you!"
By the time Edmond Dantes floated by, Gudako was certain that the gacha was basically messing with her, waving all of these SSR servants just out of her reach.
As she slipped into the darkness,a voice rang out, clear as day. "I ask of you, are you my master?"
Ah, she thought. Artoria, the only SSR that ever came to me. She reached out her hand grabbed onto Artoria's cape, surprised that it was tangible. And so she clung onto Artoria's cape as they floated away into the void.
"Wait a minute, where are we going?"
Emiya Kiritsugu gazed stoically at Avalon, the sheathe of the holy sword Excalibur. He had prepared years for this, to summon the strongest servant, King Arthur, also known as the King of Knights. With Avalon as the catalyst, there was absolutely no way that anyone else could respond to the summons. So why was it that he couldn't shake off this feeling of impending doom?
Irisviel, who was standing next to him, seemed to notice his unease. "It'll be fine, I believe in you." She smiled at Kiritsugu.
"Yes," he replied. "Yes, that's right. We'll summon King Arthur and win this war." He placed Avalon on the altar and stepped next to the summoning circle.
Shaking off any lingering doubts, it was time to begin, for better or worse.
"Servant Saber has responded to your summons. I ask of you, are you my Mas-" Saber abruptly stopped as she realized that something was clinging to her legs. Everyone looked down to see that an orange-haired girl was laying on the floor with her arms wrapped around Saber's legs.
"W-what is this?!" Saber exclaimed as she tried to remove the girl from her legs, who had a surprising amount of grip strength.
Irisviel grabbed on to Kiritsugu's arm nervously. "Oh dear, what's happening?" Kiritsugu could only respond by trying to grab a gun he always kept on him, only to somehow fumble and drop it, such was his shock.
"Ow! Stop kicking me!" the orange-haired girl casually lifted Saber up. "Oh, it's just you, Artoria."
"W-who are you?! Why do you know my True Name?! Put me down!" Saber had a dangerous look in her eyes as she summoned her invisible sword and started waving it at the girl, only for her to respond by casually dodging all of her swings. Meanwhile, Kiritsugu scrambled to pick up the gun he dropped, only to accidentally trip over his own legs. Irisviel just had a horrified look on her face, not noticing that 3 Command Seals had etched themselves onto her left hand.
