At the rooftop of Tokyo High School, a man with long silvery-white hair glanced at the city with his red eyes, wearing glasses, looking silent and calm. His face unchanging, observing things through the eyes of a man that has lived for thousands of years. His wisdom and experience were superb beyond comprehension.
He slowly heard someone walking upstairs, reaching the rooftop as well, and looking at him in silence. Her long purple hair waving by the wind as the two-face done another. The terrace-like rooftop, which didn't actually have a roof, but it was more like an open area for recreational activities and also to admire the entire school, was a very open area, quite comfortable for this face-to-face between two powerful beings.
For a moment, their crimson eyes glanced at one another. None talked, it was as if they were analyzing one another instantly, this was but a single second, but it felt like an eternity.
"Kireina, you're here. What did you wanted to ask me so urgently?" Noah asked gently. "I came here only in consideration that you're my student, but I hope you don't do this again." "..." Kireina remained in silence for a moment. "I know who you are."
"Hm?" Noah tilted his head, acting clueless. "What do you mean with that?"
"It's strange you showed no hostility, despite the reason you would be here," said Kireina. "Honestly, we have the same goals."
Noah decided to drop the act.
"And so it seems to be the case. We cannot be too explicit, however. Or everything might come down rather quickly, right? A force beyond our control is taking over this place," said Noah.
"I am sure you could break it, Emperor," smiled Kireina.
Yes, she immediately knew who he was.
Even when she had never met him in person before.
She simply could tell instantly.
Her Cosmic Eyes could see through all things, and even now, she could activate their power.
She had heard about Noah from her mother before anyways, the boy born from a fragment of Azathoth's true soul.
Formerly a human from a parallel Earth, turned into a vampire through the power of a crystal from the Vampire Progenitor, a vampire from Abyss that had appeared in his world as a monster through the Gate Phenomenon.
This phenomenon was caused by Kireina's own Miasma and Chaotic Soul Fragments raining down into this parallel Earth, causing an apocalypse that twisted the pillars of space and time.
She knew all of this because Chaos told her long ago, before she had gone almost completely silent now...
"Oh, so you address me by such a title, I see," Noah nodded, smiling. "Kireina. I've heard about you since you arrived in my... turf. And I know what you've been doing there. You've been, mostly, a nuisance. Just like the others. Stealing the sun, and then messing everything else, attacking the families... It's not good. If it wasn't for all of this, I would've gone to personally eliminate you."
"So that's how it's going to be," Kireina nodded, smiling. "I thought we could become friends at least, professor! What a shame..."
"...Don't act so friendly with me, spawn of chaos," said Noah with a calm voice, and an expressionless voice, right inside of Kireina's mind. "I've fought your kindred and devoured them all. And I can do the same with you and your little soul. If I please."
"How scary," Kireina said, relaxed. "Unfortunately for you, it seems you want to play the game?"
"I've realized this Dungeon is not a Dungeon but a World, a Dimension," said Noah. "A parallel world had been created within my own world, disrupting the pillars of reality. I tried to destroy it, and I felt like I could. But I realized my world would be in risk of being destroyed."
"So it's completely anchored then..." Kireina nodded. "I see, that makes enough of an excuse for you to pretend being a professor then?"
"...It was a suggestion from my wife," said Noah. "And I thought it was a fine idea, if
anything. It would allow me to infiltrate this place better."
"What a smart wife you have, can I meet her?" wondered Kireina.
RUMBLE!
Noah squinted his eyes, his aura growing tremendously powerful, completely making Kireina feel like she was an ant before an elephant.
"I told you to drop your act," he spoke. "What is that you desire out of all of this?"
"Frank is my friend... And also a lover," Kireina said. "So I came here to save him too. But yes, we have similar purposes. However... Noah, if you intend to kill Frank, that won't work as you think so."
"..." Noah remained in silence. "I considered it, but yes, I guessed and reached the same conclusion as you."
Noah walked around the rooftop, his aura suddenly transforming into images.
The image showed the parallel world they were on right now, and Frank within it.
"Frank has become an Anchor Being within this Parallel World, formed from his own existence," said Noah. "To kill it would mean that the world would collapse and so the dungeon, and therefore, the destruction to Abyss would be the same as if I tried destroying the dungeon myself."
His aura showed a figure of him beheading Frank, only for the entire world to collapse and be destroyed, and so Abyss with it.
"Yes, exactly," nodded Kireina. "We must play by the rules the monsters that created this made."
Noah was hiding another fact why he was doing this though.
Clementina.
He wanted to save her, after seeing what they made her become...
What the Outer Gods turned her powers and soul into...
A crying, weeping, frozen moon.
He couldn't accept that.
"I am sure by now that Frank is the one that possess the Key," said Kireina. "But we cannot forcefully take it from him. We must first help him remember who he truly is."
"And for how long do you plan to do that, Kireina?" Noah asked.
