Thank you to all my reviewers! Earthpaw...thanks for the almost-confidence. moon-bunny735...no, it's actually gonna be Seto/Another Senshi. Usagi (Serena) belongs to Mamoru (Darien), so sorry. And while that would be interesting, I'd see her more as someone who might annoy the hell out of him while he liked her. Bunny Aino--Yeah, I could see that too, hence the reason that I wrote that. And yeah, this will keep coming up because Artemis and Mokuba are quite good friends, and Mokuba is a little more mature then anime and sometimes manga Minako.Ai, Cor-chan, and bluedragonflyofdestiny thank you as well. Everyone else can go and (taken out for rating purposes).

Part 2: The Tres Leches Cake

When Kaiba had been younger, he had attended a party with his adoptive father. Unlike any other time, Gozaburo Kaiba had not kept him on a tight leash, and thus Kaiba had been able to wander the party until he ran into a young girl, about his age. She had dark hair that seemed to alternate between purple and black, depending on the lighting, and lovely purple-blue eyes, which also seemed to change in the light. She had spotted him first, he was sure, but he had moved first to see her. She wore a white dress with pretty flowers on it that he recognized as casablancas.

"Those are pretty," he told her, not knowing how else to start a conversation.

"Thank you. My father's assistant gave them to me."

"Do you what they are?"

"No."

"They're called casablancas. They're named after that city in Africa, and some say they bring up bitter-sweet memories."

"Why?"

"I don't know."

She touched the flowers then picked one off and handed it to him. "Here."

Kaiba had been surprised, and asked, "Why?"

"Because you told me what they are."

"I can't accept it."

"Why not?"

"I haven't give you anything in return."

"Call it a favor. Now you owe me."

Kaiba thought quickly, looking around before taking the flower then saying, "Wait here." He was off to get it, then came back with two plates that had a piece of cake on it.

"What is it?"

"I don't know. It's a cake."

The two tried it, and the girl giggled. "Tres Leches."

"Huh?" Kaiba tried, the sticky cake coating the top of his mouth.

"That's the name of the cake. I guess we're even now."

The two giggled together now, and with the cake done Kaiba gave a polite bow. "I'm Kaiba Seto."

The girl returned his bow. "Hino Rei."

Right before the party had ended for him, the two had talked about their lives. Kaiba had told her that he was adopted, and was lucky enough to have his younger brother with him. Rei said her mother had died when she was young, and thus she was an only child. After this, though, she heard that she was going to live with her grandfather at a Shinto shrine in Tokyo. Kaiba felt extremely saddened by this news: he wanted to see her again, maybe at school or something. Or even see if she could come over when he wasn't being forced to study non-stop. It would be nice, and Mokuba would like her, he knew that much.

He then saw Gozaburo coming towards them, to take him away, and he did something he never thought he would be able to do. He quickly moved and gave her a kiss on the lips.

Rei looked surprised and he shared in her surprise up to when Gozaburo grabbed him and pulled him out the door.

"You think you found his wife, Nii-sama?"

"I heard Yugi mention finding a cat," Kaiba told him, "It might be her. As to the owner…well, I'm not sure. I put something out and also put up a picture of him as well as a description in the papers. If she's out there, she'll find out and come by."

"You didn't put up a reward, did you?"

Kaiba had considered it, but decided against it at the last minute. "No, but I also checked and didn't see anything about lost cats anywhere before I put up the ad."

Mokuba smiled finally and nodded, happy and said, "I'll go tell Artemis. Thank you, Nii-sama!"

After Mokuba left Kaiba smiled slightly. His little brother, being happy…that made him happy to an extent. He loved the fact that he could make him happy, though at times he wasn't sure if he was completely happy or just acting. Maybe…no, Kaiba held onto the thought that he was happy, and that made him happy and able to move through the day at least.

"Artemis," Mokuba said, coming into his room and seeing the cat perk up at his voice. Artemis smiled at him as Mokuba said, "I have good news. Nii-sama thinks he might know where your wife is!"

"He does?" Artemis asked, then stood up. "That's great! Where?"

"He said Yugi might have her. You know, the one my brother's always trying to beat."

"You told me about him. I wouldn't be surprised if she was with him, though if she knows what happened to the group is something I'm worried about too."

"You mean your owner and her friends," Mokuba nodded, remembering what Artemis had told him earlier. "Nii-sama said he didn't hear anything about a cat missing matching your description, though. Do you think that…well…that…"

"No," Artemis said, turning his head away. "I have to have faith that they came back, that they're alive. Something happened, I don't know what, but I have faith that they came back and we have to find them."

Mokuba nodded, "Then I'll have faith! I had faith that my Nii-sama would wake up, and he did. He woke up and came to Pegasus' island to rescue me, so I'll have faith that they came back from that place and are here, and that we'll find them."

Artemis nodded, then suddenly bristled. Mokuba looked at him, now worried. "What is it?"

"There's something here that shouldn't be, something…evil."

Mokuba heard the door handle turn and Artemis growled. Mokuba moved farther away from it as the door opened and a dark figure was in the doorway.

"Who are you?" Mokuba demanded, trying to sound commanding but failing slightly.

The figure didn't speak, and Artemis bristled even more, growling like a cat who was warning another away. Mokuba was back in a corner, and too far away from anything to try and warn his brother. What could he do?

Yugi looked up at KaibaCorp's tower then at Luna. "Are you sure?"

"I did feel something odd coming from here, Yugi, make no mistake."

I do as well, aibou. It almost feels like the power of Shadii's two Millennium Items.

"Two Millennium Items? I hope Kaiba's okay."

I still don't understand why you get so worried over him. He's a prick.

Luna looked over at the other Yugi, "Either way, reasons are reasons and you shouldn't be so cruel to him."

I have my own reasons for being rude to him, Luna. But we should check it out, anyway. This doesn't feel right. There's something…different…evil, in there as well.

Yugi raced to the building, narrowly missing a woman with dark hair that seemed purple who was also heading into the building.

Yugi would have expected some activity, something going on, but there was…no one. The only feeling was a strange electric feel in the air, and Yugi swallowed, trying to fight back the fear that was rising. Luna was on his shoulder and looked over at the girl next to him before blinking and whispering to Yugi, "Yugi, that's one of the girls I told you about!"

Yugi cast a quick glance at her then back to where an elevator was. "We should go see if Kaiba's okay."

The girl looked at him and said, "Kaiba Seto?"

"Yes. Do you know him?"

"From before. I came here to see how he was. I'm Hino Rei."

"Mutou Yugi." He looked around. "This isn't good."

"There is something evil here," Rei said, holding a small piece of paper in her hand. "We have to find Seto and anyone else, try to get them out of here."

The two headed for the elevator, Luna explaining to Yugi that Rei was a priestess and had powers. She also was one of the Senshi girls that Luna had told him about, who had protected the princess and who were now missing.

They rode up to the main floor quietly, both unsure as to what would happen.

The man was dark colored, and by his dress he was Egyptian. He was holding a scale and currently Kaiba was standing, demanding who he was and why he was here.

"Who I am is unimportant," the man said to Kaiba's first question, "As to why I am here…you are part of an ancient prophecy. One who will destroy the one whom I and my bloodline have waited nearly three thousand years for the return of. I cannot allow you to destroy or to attack him anymore."

"What do you mean? Are you talking about Yugi?" Kaiba sneered at the man, "I think Pegasus gave Yugi more problems then I ever did."

"It does not matter who has given him more problems, in the near future you shall strive to defeat him and you will end up releasing untold chaos upon the world, just as you did to bring about the downfall of the Pharaoh and his servants."

"Could you explain this to me, or are you just babbling now?"

The man glared at Kaiba, then moved to reveal Mokuba. His eyes were blank, and currently growling lowly at the man was the white cat, Artemis, from Mokuba's shoulder. The man moved to touch Mokuba's hair and the cat lashed out, obviously not allowing the man to touch Kaiba's little brother anymore then he had before.

"Mokuba!" Kaiba started to move when suddenly the Egyptian set down the scales between them on a small table, and removed a small feather from his turban. Kaiba just as suddenly found it impossible for him to move.

"In what is called the Book of the Dead, the souls are judged by the Scales of Truth. On one side is the Feather of Ma'at, and on the other is a person's heart. Let us play a game…"

Kaiba glared at the man.

"If you answer all the questions I ask truthfully, then I will release your brother, and allow you peace. If, however, you lose, or answer one question without the truth in your heart, then your brother will remain as he is now…a mere puppet with no will and only a cat to protect him."

Kaiba felt the small letter that he had been holding crinkle as he made a fist.

"If you lose completely, though, it will not matter how your brother is, for your soul will be devoured by the great demon."

This was just getting better and better. Kaiba glared, "So I have no choice. Either I tell the truth completely, or I lose my brother or my life."

"That is correct. Now, shall we begin?"

The paper felt like fire under his hand, and for a moment he saw red but nodded. Strangely enough, the red stayed. For a moment, he saw the differences. Gold energy was around the scales, as well as the ankh-shaped key around the man's neck. It also glowed around Mokuba. The spot around Artemis, however, was colored silver, almost like moonlight. But next to the man was two dark shadows with snake eyes, smiling at him and obviously manipulating the mystery man.

How can I see them? What was--the letter from Rei!

He had just recently gotten a letter from Hino Rei, saying she was coming by to say hello and giving him a strange item that she said was an ofuda, an anti-evil scroll.

So how am I channeling it?

"The first question: do you seek to destroy those weaker then you for your own gain?"

"Yes."

The scale tipped to the side of Ma'at. The man looked surprised and looked at Kaiba. "You did not seek to lie?"

"Why should I? I'm in a business. In such things, you must step on others to get what you want, to get what you need. I stepped on others to get my brother back, and I would gladly do it again if it meant saving him."

The man blinked and the two dark figures seemed to try and grab at him. Kaiba glared at them and felt something from deep within him, some unknown and forgotten power, tug at him.

The Egyptian regained his composure. "Second question."

Yugi and Rei raced down the hall, the spirit now worried. Someone is using the power of the Millennium Items in there!

"Kaiba!"

The two stopped when they saw Mokuba standing the doorway, and somehow Yugi knew that, like Anzu had been, he was under the control of the Millennium Ankh.

Rei wasted no time, though. She lifted up the small scroll, which he now recognized as an ofuda, and began to chant.

"Rin, pyou, tou, sha, kai, jin, retsu, sai, zen. Akuryou taisan!" the ofuda flew to touch Mokuba's back and then stuck there, just as Mokuba let out a gasp then said, "Nii-sama!"

Yugi ran up and moved Mokuba out of the way, knowing something bad was about to happen.

Shadii was indeed there, and between he and Kaiba was the Millennium Scales. "Shadii, stop!"

Shadii turned to see Yugi there, and Yugi felt his control leave as his other side took over. Shadii glared at him. "There is no stopping this. The man is the reincarnation of an evil priest, and thus must be stopped before he brings ruin to us all."

"Kaiba Seto will not do that," Rei said, now holding onto Mokuba, protecting him, "Wake up. You are being controlled."

"I?"

Kaiba pulled out the small scroll from his hand and held it up, offering it to Shadii. "Try. If I am wrong…well, I suppose you could always send that monster of yours to eat my soul."

The paper stiffened and suddenly jumped from Kaiba's hand to Shadii's chest, just above the Millennium Ankh.

"No fair…no fair…" a voice hissed from the darkness that had appeared just as the fire seemed to engulf Shadii and then disappear, leaving the two shadows.

"You ruined all of our fun…now…"

"WE MUST KILL YOU!"

The two dark figures emerged and headed straight at Kaiba.

"Nii-sama!" Mokuba broke free of Rei's hold and raced over to stand in front of his brother and the attack when something dark filled up the ground behind them. The two youma stopped and suddenly backed up as two very-real Blue Eyes White Dragons emerged and grabbed them before disappearing once more into the darkness.

Rei blinked in amazement, as did everyone else. Shadii was the first one who spoke, "They opened a way into the Shadow Realm…"

Part 3: The Four Senshi

"Artemis!" Luna said, now gaining everyone's attention as she raced over and the white cat who had been perched on Mokuba's shoulder jumped off to greet her, both purring loudly. Kaiba looked over at his rival and said, "I guess that solves one part of the mystery."

Yami Yugi nodded, his arms crossed. "But not how you are able to call the power of the Shadow Realm, or how you called forth two Blue Eyes."

"He wasn't the only one," Shadii told the two. "His little brother used the same power, calling the same animal."

Rei seemed confused. "Wait. A cat talks, two blue dragons just drug off the enemies, and you were being influenced by evil and something odd. Care to explain it all?"

Kaiba looked at her and said, "It's long."

"What's the short version?"

Mokuba answered, "There are weird items called Millennium Items. They have power over this place called the Shadow Realm, and are used to either bring out a person's nature or make monsters real. If you lose in a game, or cheat, then you have to go through a 'Penalty Game', which is really bad. Yugi holds the Millennium Puzzle, and that guy," he pointed to Shadii, "holds two others. Another guy, Pegasus, held the Millennium Eye, but we don't know what happened to him."

Rei looked over at Yugi then Shadii. "You said he was the reincarnation of an evil priest?"

"Yes. It was only recently that we were able to look at the stone slab which holds the Pharaoh's Memory. The resemblance to Yugi and Kaiba is too uncanny to be ignored."

Luna looked over at Shadii. "A stone slab with the Pharaoh's memory? How is it unlocked?"

"Supposedly, but three extremely rare and powerful cards, known as Egyptian Gods. They were created by Pegasus, but due to the power, as well as an ancient power revived simply by researching these cards, only one was made of each and all were supposed to have been hidden. However, I recently heard that they were stolen."

"This just gets better and better, but I fail to see how the cats worked their way into it," Kaiba pointed out, motioning to the two cats that had brought Yugi there and obviously knew Rei.

Luna was the one who spoke, "I explained a little to Yugi. My name is Luna. You already know Artemis…though only Mokuba can understand him at this point. We are the advisors to a group of fighters known as the Sailor Senshi. They were supposed to protect the Moon Princess and help to create her kingdom here on Earth. However, something happened recently which has separated the Senshi and made us lose contact with the Princess and her Prince. The last thing I remember was reawakening shortly after the Princess had married. After that there was an attack, as far as I can tell, but as to the nature of the attack or what happened afterwards to the Senshi I don't know, and neither does Artemis. We need to find her, though."

"Why?" Rei asked.

"Those beings which tricked Shadii and nearly attacked Kaiba and his brother were youma, whom the Senshi often fight. This would mean that the person who attacked the Princess is after the Millennium Items, or perhaps those who hold them."

Yami Yugi and his aibou seemed concerned now, Yugi more so then his darker side. Another person was after his other side, and he was unsure if he could protect him or help as he did the last time. "Luna," Yami asked, "you said that Rei was one of the girls who had been a Senshi, didn't you?"

"Nani?" Rei said, looking up quickly, "You're not serious, are you…Luna, was it?"

"You were Sailor Mars, the Senshi of Fire," Luna said seriously, "and one of the Princess's best friends. You don't remember any of it?"

Rei put a hand to her head and blinked. "I remember…a little…but something happened to our power, and we couldn't protect her…no, wait…there were others, they protected her but we couldn't for some reason!"

"Others?"

"The ones with a…sword and mirror…and a glaive…"

Artemis said something and Mokuba blinked. "Outer Senshi?" Artemis spoke more and Mokuba translated, "The Outer Senshi were supposed to protect their system from outside invaders, and ended up being part of the group. They're more powerful then Rei and the others. There are…four…each, of both groups."

Rei blinked at that and said, "Uranus, Neptune, Pluto…and Saturn."

Luna looked over at Rei, obviously worried. "Don't try so hard. It will all come back in time, Rei-chan."

Rei nodded and Kaiba put an arm around her protectively, almost without noticing it. Luna looked over but said nothing as she turned back to Yami Yugi. "I was wondering…could Yugi possibly try to heal Artemis like he healed me? Perhaps we could get a better idea of what was going on with his power after that."

Yami blinked. "You don't think it's part of the Millennium Puzzle, or our connection?"

The group looked over at the two, and Luna explained that he had healed her and allowed her to be understood. Shadii seemed confused at this and he said, "I have never heard of this, but the power of the Millennium Puzzle is a riddle in of itself. What the full extent is even I do not know."

Yami nodded in agreement, but said, "Yugi will see if he can do it again. He's not even sure as to what caused the first one, and wishes to see if he can figure it out."

There was a brief pause as he changed back to the normal Yugi, and he walked over to Artemis, holding out his hand. Artemis came forward and nuzzled his hand, like Luna had done, and once more Yugi jumped back, as if shocked. This time, instead of hitting the carpet, he backed up into Rei.

The small glitters that had gone to heal Artemis turned into an abrupt burst of light and Yugi jumped back, rubbing his hand while Rei jumped back as well, though Kaiba stopped her from going far. On her forehead faintly appeared a red symbol and she blinked before it disappeared. Artemis shook his head and sneezed before looking over to Yugi. "Thanks!"

Rei put a hand on her head and looked at Yugi with a confused expression. Kaiba cast Yugi a glare, as if to warn him away from touching her again. Mokuba looked confused, as did Shadii, who had been holding both his Millennium Items. Now, he shook his head. "That is not the power of the Millennium Items."

Yugi turned to him. "What? But…I mean…"

"I understand your concern, Yugi, however that is indeed not a power that comes from the Millennium Puzzle. That power comes from something else entirely."

"…the ginzuishou…" everyone now turned to Rei. "That's what it felt like. The ginzuishou…only…it felt different too."

Luna and Artemis blinked and looked at each other before Artemis said, "Rei-chan, that's impossible. Only Usagi-san and Chibiusa-chan held the ginzuishou of any sort."

"But it did feel like that power, or something akin to it."

"Care to explain what a ginzuishou is?" Kaiba asked.

Luna nodded. "The ginzuishou is the crystal that the Moon Princess inherited. It is a powerful crystal that connects itself to the owners life-force and cannot be taken away without the death of the owner, or unless the holder has Lunarian blood within them. Usagi-chan is the reincarnation of the Moon Princess, and thus, while she was born human, her ancestry is Lunarian and she can hold the ginzuishou. Chibiusa is…slightly more complicated, but she does have the Lunarian blood as well, though her ginzuishou is slightly different."

Mokuba looked confused. "So why would Yugi's power feel like it?"

Luna shook her head. "I don't know. I've never heard of anything like that, and our access to the Moon and whatever archives has been depleted by the disappearance of the Four Senshi as well as the Princess."

Kaiba sighed and looked over at Shadii. "I don't suppose you have someone that could help us out, or some insight as to what we could look into?"

Shadii nodded. "I have a few ideas, but not many. Perhaps Artemis can help as well?"

Artemis nodded, looking over at Luna and the two quickly whispering before seeming to agree on the outcome of their conversation. Luna walked back over to Yugi and jumped up onto his shoulders while Artemis went to Mokuba's shoulders.

Rei looked over at Kaiba. "If it's okay, I'll stay here. My dad was trying to have me stay over, demo…"

Kaiba nodded and Mokuba seemed completely happy about the whole thing. Shadii bowed to Yugi before he left the group alone to head home and sort things out.
