Chapter 01: The Incident

"You dare summon me?" Kaiba growled as he stormed into Isis' office at the Domino City Art Museum.

"I believe it would be most beneficial to you," Isis replied in a calm voice, seemingly uninterested by Kaiba's rough demeanor.

Rolling his eyes for good measure, Kaiba said, "Doubtful."

"Then why did you come?" Isis asked, irritating Kaiba since he didn't actually know the answer to that question.

"Just shut up and get on with it," Kaiba ordered as he defensively crossed his arms over his chest.

Bristling at the tone, Isis reprimanded him, "It would serve you well to learn respect."

"As if you deserved any," Kaiba scornfully shot back with a sniff of disdain.

"I am only trying to assist you," Isis informed Kaiba.

"Then hurry up and get on with it," Kaiba snarled, feeling as if he had wasted enough time.

Taking a calming breath, Isis began, "The Millennium Stele—"

Snorting rudely, Kaiba demanded, "This shit again? I told you I don't believe in that nonsense."

"How can you refute the evidence before you?" Isis asked.

"Because it's not evidence, it's bullshit," Kaiba countered.

Frowning at Kaiba, Isis said, "You must learn—"

"The only one who needs to learn anything is you to stop wasting my time," Kaiba interrupted her again.

Taking a calming breath, Isis said, "I wish to speak with you about the pharaoh."

"Yami?" Kaiba scornfully asked. "I definitely didn't come here to listen about him."

"He is important to you—"

Interrupting Isis again, Kaiba refuted it, "No, I refuse to believe that!"

"Are you willing to let me speak?" Isis questioned irritably, getting annoyed by Kaiba's behavior.

"Do you have anything worth listening to?" Kaiba retorted.

"Yes, if you would let me finish," Isis icily said.

"If it's more of this Millennium Item bullshit, forget it," Kaiba told her as he turned to walk away. "I never should have come."

"Do not walk away from me, priest," Isis warned.

"Don't call me that!" Kaiba yelled at her as he turned back around to face her, the words having the desired effect of stopping him in his tracks.

"Then do not take me so lightly," Isis told him. "I am not to be trifled with."

"Or else, what?" Kaiba questioned, hearing the threat in her tone. "What could somebody like you do to someone like me?"

Narrowing her eyes at Kaiba, Isis replied, "Plenty."

Rolling his eyes again at her attempt at bravado, Kaiba declared, "I find that hard to believe."

Ignoring the slight, Isis tried to persist with her previous thought, "As I was saying, the pharaoh—"

It was more than Kaiba wanted to hear and he decided, "Whatever, I've wasted enough of my time with you," as he turned away from her. He had been foolish to expect anything different than her usual nonsense.

When Kaiba started to walk away, Isis decided that she had had enough of Kaiba's arrogant attitude. She would not be taken so lightly by him anymore. With that in mind, Isis began changing an ancient incantation that froze Kaiba and prevented him from leaving.

Struggling against the weird feeling enveloping him, Kaiba managed to ask, "…what?"

Isis neglected to answer him; she merely continued her enchantment until Kaiba suddenly knew no more and blacked out, still fighting to the very end.

A/N: I'm sorry, I know it's a super short start, but soon we'll be back up to the verbose chapters you've come to expect from me, promise.

Special thanks goes out to Nekoma0201 and Sethycakes for having a conversation with me on Twitter back in 2011 that spawned the idea for this fic!

I also have an exciting announcement, which is that with this story, I will be resuming weekly updates again. I will do my best to stick to the schedule, but in the event my health interferes again, I will return to bi-weekly updates, but I will announce it if the situation arises. But hopefully it won't!

NEXT CHAPTER:

"So what was it that you needed to talk about so urgently?" Yami asked as he entered Isis' private office at the Domino City Museum of Art.

The next chapter will go up on Sunday, June 22nd, but until then I look forward to hearing your thoughts! I know there's not a lot to go off of here, but I promise that this will be a fun ride and I hope you join me on it!
