Author's Note: Look at that, a new chapter in a few days. I haven't done that since Chapter's 4 and 5 lol. Anyway, I made a slight change to the chapter. I said I was going to bring in four people from Vexen's experiment, but that's more of a pain so I just put the original two that I wanted.

Anyway, I thought of something interesting. Sephiroth's Second Life Trial Filler Arc isn't canon, meaning it doesn't what I put in it, it's not really relevant to this story. So, for that story, if anyone wants to see something in this universe, request and I'll do it. Other then that, relax, read, review.

Sephiroth and his group, along with Summoner Yuna's went outside. Right off, they could hear practically the whole continent of Spira singing the Hymm of the Fayth. Larxene explained to him, who got the information from Yuna, that Yu Yevon took Jecht, Tidus' father, and made him into the Final Aeon who fused with it. Jecht apparently likes the Hymm and singing it will bring him out of hiding and slow him down, hopefully.

"Impressive tactic," noted Sephiroth. As the words left his mouth, the airship shook and most of them lost their balance.

Sin was covered in a pink and purple aura. It rose so that it's mouth was facing the sky. There the pink aura gathered into a sphere, and started gaining power. Sephiroth recognized this attack in a different form, from facing it earlier. The sphere had certain orbs flying inside it, like molecules and atoms. This sphere seemed to have a gravitic effect as the water was attempting to pull upwards to it, and the clouds around them started gathering. Sephiroth could even since that comets were heading this way. Before any of these could connect, Sin let it loose. It was so powerful, it split in six different ways in sphere, which one went under them.

It was silent for a minute but after nothing happened, they all looked around. From Sin's position, the clouds and water had formed to a tunnel like area. Not only that, but some of the ground was gone, as if a ball went through them. The water was parted for the longest time, probably from the after effects of the attack. Soon it came clashing in, as a tsunami. It hit the shores, and the ground, and was so fierce, it was making the ground explode. It became a tunnel of explosion and hit the airship, though not doing a lot of damage. Afterwards they all got up and stared at Sin, who was doing the same to them.

"If Xenmas ever got complete control of that thing, it would be the end," stated Sephiroth a little nervous. "I have never seen so much powerful before."

Soon Cid, the captain of the airship and Yuna's uncle, Rikku's dad, and Larxene's brother, came unto the outside intercom. He said they found something at the base of Sin's arm, and should attack it. They all agreed. Sephiroth could see in the far, far distance, that the Deepground helicopter fleet was coming. They all got ready as they approached Sin's left arm. There was indeed something there. A type of plant, eye looking thing that was popping out.

The Airship got close and they began fighting. This part of the battle was easy. Auron, one of Yuna's guardians, broke it's defenses with his attacks while Sephiroth, Tidus, Wakka, Cloud, and Zack all attacked physically with Lulu, Kadaj, Larxene and Demyx attacking magically. The thing soon cringed up and they knew they won the easy fight so far. Sin began moving away in pain.

The Airship went to Sin's side, and everyone felt something beneath them move. They saw two long needles popping out underneath the Airship, with a few tubes connecting it to the ship. The point of the needles started glowing with electricity, and just a huge bolt of it at Sin's arm, severing it. It began falling towards Bevelle, dissolving. Next thing they saw was a couple missiles coming from the Deepground fleet, destroying the arm before it became a Sinspawn. They proceeded on to the other arm.

The second battle was like the first, easy to defeat. With seventeen people fighting, it was cake. The second arm came off with the Airship's weapon with the Shinra fleet behind it destroying the remains easily. Soon Cid complained that the weapon is busted and that they should retreat for now. Tidus said no and jumped overboard, with his group behind him, landing on Sin's back.

"Shouldn't we follow?" asked Yazoo cooly.

"They got it," responded Sephiroth smiling. "This place can't count on us the whole time."

They all smiled as Tidus and his group battled Sin's back. They summoned Anima which Sephiroth found a little interesting. Soon the won the battle and Sin shook them off. The Airship came over and picked them up as Sin roared in pain and started falling, the two holes on his sides where his arms used to be, leaking out loads of pyreflies as he went down. Sin hit the ground hard, bouncing off it a little, and coming back, leaving a huge trail of debris, dust, and rock behind him. He laid there motionless for awhile. The group decided to head back into the Airship.

"Looks like we're winning," commented Loz looking out of the window next to his brother and Sephiroth.

"It's not over, but it's a good start," agreed Sephiroth. "Remember, after this, we get inside Sin and Larxene and Demyx lead us to their hideout."

"Sephiroth," said Kadaj in a hushed tone. "Didn't it ever occur to you that they might be deceiving us?"

"Yes, but Axel himself told me that Larxene was part of their rebellion," explained Sephiroth. "Apparently so was Demyx. I trust them. If by chance, they try something, I won't hesitate to kill them. On a different note...Kadaj?"

"Yes?"

"Your room was next to mine right?"

"Yes, it's next to yours that's next to the elevator," explained Kadaj. "Why?"

"Who were you sharing the room with? Your brothers?" Loz and Yazoo shook their heads.

"We shared our with Reno and Rude," answered Yazoo.

"Was Yuffie with you then Kadaj?" asked Sephiroth bluntly. Kadaj went pale but nodded. Sephiroth brought his head next to his ear and whispered, "next time you and Yuffie are having a moment, do it quieter."

Kadaj turned around and flung his arms into the air cussing. Sephiroth simply smiled. He caught some movement at the corner of his eye. Sin's back sprouted four insect like wings and began to fly to the top of Bevelle's tower, clasping it with it's two back arms. Sephiroth got the idea when he heard the lower door open. They all left with them.

They all prepared their weapons as they faced Sin directly, slowly moving towards him. For now they couldn't use any weapons. Most of them were too far, but that just meant they had to use long ranged weapons, and magic. From Tidus' group, Lulu and Yuna used their magic while Wakka constantly hit Sin with his Blitzball. Loz and Yazoo constantly send rounds of lead into Sin as Kadaj shot many Bolt 3 spells. Sephiroth was using third level spells from a distance.

Sin got closer and now it began opening it's mouth, gathering energy, just like before. Tidus, Auron, Cloud, Zack, and Sephiroth all began hitting Sin with all the got. Yuna Summoned Anima and sent it's special "Pain" attack into it, causing more damage. Larxene used her unbelievable speed with her constantly regenerating kunai to hurt Sin more as Demyx shot water bullets from his sitar. Kimahri used his Ronso attacks as Rikku used her alchemy to help everyone. The onslaught became so brutal that Sin cringed.

They knew they won as Sin opened his mouth wide, showing a portal of sorts. It let out loads of pyreflies as the ship entered. The second they hit the portal, they crossed through to it's dimension. There, it seemed like they in the Farplane, as they were flying above clouds, surrounded by pyreflies. It looked quite beautiful considering. However, the area turned red quickly. In front of them, a ghost like figure of an eye appeared and laughed maniacally. It seemed to hit them, and set them ablaze, making some scream for a second. But it was quick, and they were back to normal. Most of them turned to see what that was, but a few got the idea.

They landed at the first sight of land. Granted it wasn't land, more like water on land and mist. However they landed and they all departed.

"Tidus, you and your group want to head straight ahead," explained Larxene. She hadn't even started the sentence but the time we went away. The others followed. "Guess they didn't need me. Ok, this way is the correct way to our HQ." Pointed Larxene behind the airship. Larxene started walking that way but Sephiroth stepped in front of her.

"Larxene, I want you and Demyx to go with Yuna," said Sephiroth. She looked shocked and so did Demyx. "It's not that we don't trust you, but the Organization could win, and to make sure they don't gain absolute power, Sin must be destroyed. But Yuna has to do that, so I need you and Demyx to leave with her ok?"

Larxene still looked shocked but nodded. "I get the picture, sure no problem. I'll just fill you in on a few details. You'll soon hit a city that's swarming with Heartless. Don't bother with them, they constantly regenerate. Keep going until you arrive at a large white castle. You can't miss it. Other then that, you should be ok by yourself."

Sephiroth and Larxene stood there for a moment. "Thanks Larxene." Was all Sephiroth said leaving with the rest of the group. Larxene and Demyx rushed to catch up with Yuna and her guardians. They did after awhile. They made good progress, one third the way through. They explained the situation and Yuna thanked them for it.

The Fiends inside Sin were powerful, but they could handle them for the most part. Finally they arrived at a bunch of staircases and went up them. They were paved with weird looking staves on the outside of the stairs. When they got up to top, they saw four circular pillars, one below, two in the middle, and one on top, each carrying four elemental slots. Below all of them, was a body: Seymour Guado. Tidus and Yuna eyed Seymour who looked at them.

Sephiroth and his group finally arrived at the city. There, it was raining, lightly for now, and was dark, as if it was night. The buildings were all tall and lit up, though there was no one in sight. They could see clearly in the distance, the top of the castle that Larxene spoke of. Above it were clouds, and above that, was a large moon shaped like a heart: Kingdom Hearts.

Like Larxene said, Heartless started appearing in vast numbers. They all charged through. Sephiroth destroyed at least five per swing of his sword, but like Larxene said, they seem to come back. They just charged through the waves at Heartless, passing the large buildings and structures. They arrived at cliff of sorts, with a pale green road leading up to the castle. They didn't hesitate, and charged up it.

"They've entered the castle," announced Zexion. "Eight of them. Three of them are mediocre in strength. Two, who I recognize as Sora and Riku, are above average. Two others are notably powerful. But one, is as powerful as you Superior."

"I want everyone to handle them, but leave Sephiroth to me," ordered Xenmas. "Go to your spots as you please, toy with them as you wish, but finish them off. Vexen, send off your clones to deal with Yuna and her group. We can't have them destroying Yu Yevon."

"Superior, it seems that Larxene and Demyx are with them," commented Zexion. "I can also since Seymour with them as well, stopping them as I can sense."

"I'm sorry Superior, but I could only finish two of them, the other two I couldn't even start," complained Vexen.

"Regardless, send the clones to defeat whoever is left," ordered Xenmas. He flung his hand forwards and all but himself left via dark portals. Xenmas stood up and jumped down from his chair on the floor. "Now is the time."

The group entered the castle, looking around them. It was very vast. They were on a ground platform which was a small part in the castle, which was vast. Right off, a dark portal appeared and a big built man appeared out of it, wielding a giant tomahawk. "I'm Lexaeus. Come warriors, let me show the power of Nobodies."

"While we could all attack him at once, that only give them more time, we should go one on one," suggested Yazoo.

"Agreed, who wants this one?" asked Sephiroth. "Xenmas is mine."

"I'll handle him," stepped Loz checking his stun gun laughing a bit. He put his arms forward, as if welcoming Lexaeus. "Wanna play?" Lexaeus nodded and threw his tomahawk over his shoulder as an aura appeared over him.

The remaining seven went past them. They were on a small platform that lead to a small road. The boundary between the road and platform had a magical barrier put up around it, making sure no one got in or out. Loz chuckled, ready for the battle. As the group continued, Nobodies constantly appeared which Sephiroth vanquished easily enough. The reached another platform, where another dark portal appeared. A man appeared out of it, with dishwater blonde hair, dark green eyes and a ice shield on his left arm.

He laughed. "I'm Vexen, brains and scientist of Organization XIII. I like to see how my specimens react under pressure, so I have something for you." They all stared at him. "I recreated clones of Axel and Roxas, who have the same capabilities as them, with no memory, and I've sent them upon Yuna and those traitors." Vexen began laughing maniacally. Soon it was joined by Sephiroth's who made Vexen stop. "What's so funny?"

"You underestimate the power of Yuna and her guardians," laughed Sephiroth a little looking up at him. "They'll do just fine." Vexen growled at them.

Sora stepped up. "I'll fight you," declared Sora taking out his Keyblade. "I'll make you pay for what you did to Roxas."

"What I did to Roxas?" asked Vexen bewildered.

"We're complete and I have his memories," declared Sora smiling. Vexen growled as Sephiroth and his group passed him.

Like before, they went to a small narrow strip next to the platform. Vexen raise a barrier between them and between them and Lexaeus. More Nobodies appeared and Sephiroth slashed them away as they came to another platform, this one having a entrance to another part of the castle. But like the previous two, a dark portal appeared with a man stepping out. He had silver hair, one part covering his right eye with long bangs. He carried a book with him, a rather thick one.

"Greetings, I am Zexion," announced the man bowing with respect. "You've obviously chosen to go one on one, and I'll agree to that as well. Choose a person to fight me."

Riku stepped up with his Keyblade. "I'll fight you," announced Riku holding up his weapon, ready to fight.

"Aww Riku, I've been meaning to fight you," stated Zexion opening his book. "You'll find that I'm a worthy foe for someone who uses the darkness as their light."

Sephiroth and his group passed them and entered the new area. The entrance was sealed and Riku and Zexion were ready to fight. The group of five, Sephiroth, Kadaj, Yazoo, Cloud, and Zack all went into a new area. A rectangular room with windows surrounding them, looking outside. The windows glowed and a few Nobodies appeared. They all dispatched them quickly and the room glowed again, the entrance appearing in a new spot. They had no choice but to continue on. But before they did, a dark portal appeared and another man stepped out. He had crazy hair, long and braided, carrying six spears with him, floating in midair.

"Xaldin right?" Sephiroth confirmed. Xaldin nodded.

"Who will be the first to die at my hands?" asked Xaldin.

Kadaj stepped forward but Cloud got in front of him. "This man seems to be a bit stronger then the rest," noted Cloud taking out his Buster Sword. "I'll handle him."

Xaldin nodded as the remaining four went past them, the entrance disappearing completely. The new room was very spacious. It was a rectangular platform, below a sort of series of platforms. The ones on the sides seem to go to different rooms. There was one, right above the entrance to the next room. On it was an Organization member, with an eyepatch, covering a scar. He had a ponytail as well and yellow eyes.

"You guys haven't been good have you?" asked Xigbar. "Looks like you haven't, trying to destroy a thousand years of planning. Oh well, I, Xigbar, will stop you here." Xigbar didn't bother listening to Xenmas' orders and shot hundreds of rounds of red bullets at the whole lot of them. They all deflected the bullets as he came down on their platform.

Yazoo stepped forward. "I will fight him," said Yazoo taking out his gunblade. "I will show him how to use a gun." Kadaj stepped forward as well. "I'll join you, he seems pretty tough."

Sephiroth and Zack went on as a barrier rose to block the exit so it would be a two on one fight. The next area was a series of platforms connected by roads like stairs. Many Nobodies showed up and got destroyed with Sephiroth and Zack as a team. They destroyed a large number of them as they continued, going six platforms and the roads connecting them. They hit a door and entered it.

Inside, there were two rows with six panels on the ground, with a large tombstone like object above them. Most of them were blue, but two were red. One was glowing and Zack approached it. He looked around it for a bit.

"Looks like there's another Organization member in here," stated Zack. "He's mine."

"There still two left after you meet that one and I go towards Xenmas," noted Sephiroth. "Looks like you guys will have to fight some more after your one-on-one fights."

"We can handle it," said Zack giving his the thumbs up sign. "You just get rid of Xenmas, we'll handle the rest."

Sephiroth nodded and before he continued, noticed the red panel in front of him. It was red, with the picture of chakrams on them. "This was Axel's," noted Sephiroth. "I guess they're red when they're dead and blue when they're alive."

"There's only twelve, I don't see Xenmas'," noticed Zack looking around.

"He won't need one when I'm done with him," boasted Sephiroth. "There will be nothing left of him to even put in a grave." Sephiroth climbed the stairs at the back of the room.

Zack went through his portal and entered a balcony of sorts, looking out into the city. The portal behind him closed as large cards, the size of himself, appeared. A man appeared behind them, with short blonde hair, a goatee connected to his mustache, and piercings in his ears. "I'm Luxord, and you just made the gamble of a lifetime."

That was that, they were all set to continue their journeys, all blocked by enemies.

Yuna and her guardians, Larxene, and Demyx vs. Seymour

Loz vs. Lexaeus

Sora vs. Vexen

Riku vs. Zexion

Cloud vs. Xaldin

Yazoo and Kadaj vs. Xigbar

Zack vs. Luxord

There you go, now you know what to expect for awhile. The next few chapters will be complete battles, so hope you like that.

Preview of next chapter: Yuna and her guardians have made excellent progress, but are now blocked by the unsent Seymour Guado. They now must fight their way to Yu Yevon, and Seymour has gotten a great deal stronger since they last fought him. On top of that, clones of Roxas and Axel await the winner of the battle to finish them off. Meanwhile Sephiroth climbs the castle to meet Xenmas.
