I do not own anything to do with final fantasy X except the plot that I am writing about.

Yuna and the Final Aeon.

3.

"What? What do you mean, 'You found another way?" Yuna asked.

"I know how you can summon the final Aeon.and not die!" Tidus yelled at the summoner as she brought her staff back down to her chest, trying to think if it would work.

"Tell me." Yuna replied.

"Rikku and I were talking on the airship when she told me of the summoning, and I know how the summoner dies. Do you remember that spell that Lady Yunilesca gave you?" Tidus said in a hurry. "Use it when the pool appears, that will stop the magma from eating at your flesh, Yuna, that is the loophole, you can summon, and not die!"

"Yuna, that is what happened to Lord Braska, I was there, I saw it for my own eyes. What Tidus says makes since, the summoner goes in and the aeon comes out, when the aeon is gone, the summoner still comes out, untouched." Auron said, looking up at the great, yet devastating, beast.

~ Yuna's flash back .~ "Remember, summoner, use that move when life is threatened." Lady Yunilesca said. "I bid thee, farewell." ~ End Flash back ~

'That must have been what Lady Yunilesca meant when she said that. That is the way. Alright Tidus.' Yuna thought to herself as she looked back at the guardians.

"Alright, I will give it a go. Lulu, are you ready?" Yuna said as she held out her staff, Nirvana.

"Always. Do it, now." Lulu replied.

Yuna walked over to Lulu, looking at her in the eyes, then she raised her staff, calling the aeon. Lulu's eyes turned a golden, redish color when she walked into Yuna, fusing with her body, becoming one. Yuna's staff lighted up as the summoner swung the staff, in one circle, then spun around, the entire time, Lulu with her. The light gathered more energy as she threw it up into the air, causing the now cloudy sky to form a circle. Then this red energy came out of the circle and smashed into the bridge, though not damaging it, causing a pool of magma to appear. Yuna then threw her staff at Tidus and said

"Hold on to this for me, ok. Sacred shield." Her hands then formed into a prayer sign, locking her hands together. A dark purple orb covered her body, like the one in Zanarkand, as she fell into the magma pit. As soon as the orb, or her, was in sight, ten of these golden sparks came out and flew into the sky, one representing each aeon. As soon as the sparks went into the air, a thin, pure white beam flew out of the opening and hit the magma pit, and the high bridge began to shake, and out came this horn from the pool of magma. Then suddenly, this beast arose out of the pool. The beast was huge, having black hair, and belts all around the waist, flowing down like a tail of some sorts. The beast had the sign of Yevon on its chest that lighted up, ready for attacking.

"She did it, I hope Yunie is alright." Rikku said.

"Look at that beast, it has to be the biggest aeon that I had ever seen. Jecht's wasn't that big, and it was HUGE!" Auron said as he withdrew his sword.

"How do we get Sin over here, ya?" Wakka said.

"Here, I'll do it, ENERGY RAIN!" Tidus yelled as his sword glowed. Tidus jumped off the high bridge onto a building, going to Sin, as if the buildings were stepping stones. He thrusted himself up, now hovering over Sin, as his sword gathered more energy. Sin was now alarmed now that he was there, and now aware that the Final Aeon was called upon. Tidus threw his Calabolge's blade down towards Sin, when seven massive waves shot at the creature, hitting it. Tidus dropped on Sin's back, causing him to be trapped there.

"TIDUS!" Khimari said as he jumped onto the buildings that Tidus had used before him, landing of Sin. "Come, on back, I will take you" He said as the blond boy jumped on his back. Khimari then jumped back down on the buildings, dropping onto the bridge.

Sin turned its body around, now looking eye to eye at the guardians, and the final aeon. Sin started to open its mouth when Tidus yelled at the final aeon and the guardians "Don't let its mouth get open, it will attack then, try to keep its mouth closed!"

The final Aeon raised its hands, and gathered energy into a ball. When the energy was at its max, the mighty aeon threw the ball of energy at the previous aeon, Sin. The ball of energy hit one of its fins, and the explosion was great enough to knock the people off its feet, and some people's, from Bevelle, homes to crack, being as the entire city was made out of stone.

Sin took that attack as an opportunity to launch 'Gravisia' on the aeon. Sin's eyes began to open when the base of the aeon began to explode, causing the aeon to flinch.

* In the sphere with Yuna *

'Lulu, you can do it, do not give up, do not dismiss the aeon.' Yuna thought to herself. Yuna was a little injured from the attack that was released, the explosion of 'Gravisia' also attacked her, causing her orb to weaken a little. Yuna was in that orb, concentrating all of her energy when she saw a figure standing in front of her. She recognized him, It was Sir Jecht.

Back at the battle with the Final Aeon and Sin. *

The Final Aeon was getting tired, having taken all those hits from one of the most powerful things existing.Sin. Sin launched 'Gravisia' again, hurting the great aeon.

"Rikku, Khimari, Tidus, Wakka, use anything that you can get that can heal the aeon, and Tidus, you use Curaga, NOW!" Auron said as he pulled out a High-Potion.

The party cured the aeon when they realized that the mouth of Sin was now fully open.and gathering energy.

"What is it doing?" Rikku said as she pointed out at the mouth of the aeon.

"I don't know.wait." Tidus said as he was interrupted by Auron.

"I know that move anywhere, it is getting ready to use its overdrive, 'Tetra-Gravitation'."

Sin's mouth was all the way open when the Final Aeon burst into pyrflies when Yuna and Lulu came up out of the fading magma pit.

"What happened?" Yuna asked. "My aeon disappeared. Lulu, do you know?"

"Yes, I dismissed it, look at Sin's mouth, it is opened, I could see its energy from the eyes of the Aeon, I could see the." Lulu said as she was disrupted by a noise.

"Whats that..Father!" Rikku said as she saw the airship come back. The group got onto the airship, going away from it as Sin's mouth opened and an orb of gravity power started to glow around it, causing waters and clouds to start to get sucked into it. The group ran onto the outside of the airship, watching everything. As the energy was charged up on Sin, it all started to concentrate around its mouth when it split and shot into seven different directions. Everything got still when they saw miles and miles of craters that were in one line. The water was standing straight up when EVERYTHING started to cave in, including houses and rocks from mountains. The explosion caused the people to fall back and land on the floor. When the impact started to subside, the group went back into the Airship.

"What happened out there?" Cid asked as he walked over to Rikku and Yuna, which was right by her, and hugged them both.

"Cid, I need to go back to Zanarkand, Immediately!" Yuna said as she bowed to the pilot.

"What for? Why do you need to go back there, you already got the final aeon." Cid asked.

"I wish to speak to Lady Yunilesca." Yuna replied as she looked at Lulu.

The airship landed at the Zanarkand ruins when Yuna said " I wish to go alone."

"Why? Why can we not go?" Rikku said as she ran up to Yuna and looked her in the eye. "We are your guardians, we need to go."

"Not for this, trust me. I need to speak to her privately." Yuna replied as she started to walk out of the Airship.

'I wonder why Yuna wants to speak alone.' Tidus thought to himself.

Yuna walked into the chamber where she first met Lady Yunilesca to find her standing into the circle that Lulu was in when she received her as the final aeon.

"Why have you come back, Summoner?" Lady Yunilesca said.

"You know why. I am to give the aeon back to you. Undo Lulu as the faith." Yuna said as she did the sign of prayer.

"You are wise, you finally realized what was missing. You finally realized that you can not defeat Sin with what you had. Fine., Yevon grant the faith Lulu life." Lady Yunilesca said as she raised her hand and shot a beam of light into the sky. "You will need a new faith, you know."

Lulu felt this tingle inside of her as the life was literally shot back into her. "Everyone, I am no longer a faith, what has Yuna done?"

"So, do you know who will become the new faith?" Lady Yunilesca said.

"Yes I do." Yuna replied.

"Who?"
