Oración Seis arc

Assembly
After helping Lucy get her rent money, Team Natsu meet up with former 6th seat Yajima. They learn of the destruction of council and that new dangers are to come.

Meanwhile, former council member Ultear informs her master Hades of the Oracion Seis and their movement. The Fairy Tail members learn of the Dark Guild alliance and their plans of destroying a major portion of it. Team Natsu head out to meet fellow team mates of Blue Pegasus, Lamina Scale, and Cat Shelter. Upon arrival at the meeting place the trimens of Blue Pegasus quickly show off their handsomeness and treat Erza and Lucy like hosts. When leader of the Trimens Ichiya Wanderlei Kotobuki tried to get close to Erza she kicks him away and he gets his head frozen in ice by the arrival of Lyon. Lucy meets Sherry again and seem to continue their rivalry along with Gray and Lyon, which is soon stopped by top Lamina Scale member Jura. They later wait for the final member to show up, and got an unexpected surprise. Expecting a really strong mage, they instead receive a little girl named Wendy and her cat companion Charle. Happy develops a crush on Charle and Natsu tries to remember where he heard the name Wendy.

With all the Guild members assembled they learn of the Oracion Seis searching for a magic called Nirvana and alittle about each of its six members. Before a plan could be set up, most of the alliance runs out, searching for their enemy. With only Ichiya and Jura left behind, Jura gets stabbed with a knife by Ichiya, who is actually Gemini, one of Angel's celestial spirits. She had infiltrated their meeting and as a result, now knows about their planned ambush.

The Good and the Bad: Light Team vs. Oracion Seis
With the ten members of the light team still searching of the Oracion Seis, the airship Christina which they were planning to use in their battle arrives overhead and blows up. They are then greeted by the Oracion Seis members. Happy, Charle, and Wendy hide while everyone else tries to fight back.

Natsu and gray try to attack first but are quickly taken out by Racer. When Lucy yells their name she is surprised to see another her and gets attacked by the fake Lucy's whip. When Lyon and Sherry try to charge forward and attack, they lose their balance when Hoteye softens the ground underneath them. the trimens are taken out by racer in an instant and Erza tries to battle cobra but has difficulty hitting him due to his hearing magic. When Natsu makes up he tries to attack Midnight but is surprised that his attack went around him. He is later told by Racer that it would be scary to wake up midnight and gets attacked again. When Gray tries to attack he got frozen by Gemini. Erza tries to fight and brought out a new armor but fails and gets poisoned by Cobra's snake. Brain tries to finish off everyone but stops when he notices Wendy. He decides to capture Wendy so they can use her healing magic, and in the process accidentally capture Happy as well. Brain then launches another attack at everyone but they are saved by the timely arrival of Jura and his Iron Rock pillars.

Icihiya then uses his perfume magic to heal everyone;s injury's but is surprised to learn that his magic can't stop the poison that Erza is infected with. Erza then asks someone to chop of her poisoned arm, which Lyon tries to do and almost did but Gray stopped him. In the midst of everyone's argument Charle calms everyone down by saying Wendy can save her without the need for unnecessary sacrifices since she uses the healing magic, Sky Dragon Slayer. Realizing that they need Wendy's help, everyone agrees that their new mission is to find and rescue Wendy and Happy from the Oracion Seis.

The Enemy of My Enemy
At an abandoned city, Brain tells everyone that Wendy is the sky dragon slayer, and that they can use her abilities to heal someone who knows the location of Nirvana. He tells Racer to go fetch something, and for Cobra, Angel, and Hoteye to search for Nirvana. He also says that even if Wendy doesn't want to help them, she will when she finds out who she is healing.

As everyone splits up to try and find Wendy and Happy, Natsu asks about Wendy's dragon slayer powers, and learns that the dragon, Grandine, who taught and raised Wendy, disappeared about 7 years ago. They are later attacked by the Dark Guild, Naked Mummy, which after a little difficulty, due to the number of mages, they managed to win and locate Wendy. Natsu yells loudly and makes Racer come out of the cave to attack them. Gray chooses to fight him and managed to stop him in his tracks by freezing a tree, causing him to slip so he can't speed up.

Racer then arrives and the person in the coffin is revealed to be a near death Jellal. Happy and Wendy are both surprised to see him still alive. Happy tries to convince Wendy to not save him due to what he did to Erza, but Wendy says that she loved him and owes him a great debt, is then given 5 minutes by Brain to make up her mind. In the end she chooses to heal him, just in time for Natsu to see the revived Jellal. Natsu tries to attack him but gets blasted away in an instant. Later when he turns around and blasts Brain before leaving. Brain becomes confused about why he attacked and thinks that Jellal plans to keep Nirvana to himself, so he orders Cobra to follow him.

Realizing that Erza is in pain Natsu chooses to rescue Wendy first before going after Jellal. As Charle and Happy carry Natsu and Wendy away they are spotted by Racer who rushes towards them and knocks them out the air. Natsu realizing that Charle and Happy can't fly decides to carry everyone and run. Just as Racer was about to catch up to them, Gray casts his Ice Rampart spell to make a giant ice wall to prevent Racer from chasing them. Natsu then makes a run for it, and Gray continues his battle. Since Gray managed to stop Racer twice, he says he will kill Gray, and so their battle starts.

The Ice and the Speed: Gray and Lyon vs. Racer
Gray gets ready for battle, but is surprised at Racers speed who is able to go from in front to behind him in an instant. Racer then summons motorcycles and challenges Gray to a death race. Their battle of vehicles is one sided, since racer can still speed up and Gray can't cast spells while driving. They later enter a tunnel and upon exiting, Gray spots Lyon and Sherry. He tells Lyon to get on and tells him to cast spells while he drives. Lyon arrogantly agrees and reveals that he now uses two hands for his ice make, as opposed to one like back on Galuna Island. This surprises Gray, but Lyon reminds him that Ur taught them to use both, so he is glad.

Lyon manages to take out Racer's bike with his Ice eagles, but Racer jumps up and destroys their back at the same time. They then try to go all out against Racer, and both take off their shirts at the same time, greatly shocking him. They show good teamwork and almost managed to catch Racer, but then he speeds up even more and manages to attack them. While he did Lyon notices some birds flying at incredible speed. He then reveals to Gray that he found Racer's weakness.

After whispering something to gray he traps Gray in ice and sends him high up saying that he doesn't need his help. Racer and Sherry wonder what he was doing, and he says that Gray and him only trained together and that they aren't friends and that Lamina scale will take the credit for defeating him. Lyon then taunts Racer for having speed but no attacks and tries to lead him away. He receives many injuries before getting Racer some distance away. Just as Racer was about to pierce his throat with a knife, Lyon reveals the true nature of Racer's magic. He doesn't use his magic to speed up, he uses it to slow everything else down, but he can only affect a certain area so since he is far way from Gray he can easily attack him without getting affected by Racers magic.

Gray manages to shoot arrows at Racer and after getting hit he tries to remember his Prayer of being faster than everything else. Gray and Lyon celebrate their success but Racer refuses to lose and tears off his Jacket to reveal exploding lachryma. He then rushes towards Sherry, Gray, and Lyon intending to kill them all along with him, but Lyon grabs him and pushes himself and Racer off a cliff just as the explosives went off, to save his friends. This greatly shocks Gray and Sherry.

The Magic of Light and Dark
Natsu arrive to Lucy and Erza's location with Wendy, thanks to Hibiki using his magic to download a map into his head. He wakes up Wendy and begs her to save Erza, which she agrees and manages to do. Elsewhere somewhere deep in the forest, Jellal takes a pair of clothes and arrives at a tree bound with chains, with Cobra secretly following him. He then activates something to break the seal on Nirvana and activate its first stage.

As Erza is recovering, the gang notice a pillar of black light, that seems to be drawing black around its surroundings. Realizing that Jellal must have found Nirvana, he rushes to find him, and accidentally let Erza hear about Jellal being near by and alive. She secretly sneaks out and the gang decide to follow Natsu. Just as Wendy was starting to have doubts, Hibiki knocks her out and explains what Nirvana is and its dangers.

Hibiki tells them that he knows what Nirvana is, but didn't tell everyone back at the meeting since it might bring doubt about his loyalties. Nirvana is a spell that makes people switch between light and dark, and that what they just saw is the first stage that makes people who waver between good and bad switch places, which is why he knocked out Wendy when she was having doubts. This is shown when Sherry who is traumatized by Lyons supposed death, start to make her attack everyone she thinks is responsible starting with Gray. Later Happy brings up that if this is true than those of the Dark Guilds, will switch to good. He says that it is a possibility but if Nirvana were to activate its second stage, then it could be used to target specific people such as a guild, and the member's would kill their friends in bloody murder.

The Iron Rock and the Liquid Ground
Jura separates from his group and runs into Hoteye of the Oracion Seis. They then enter a earth battle, with opposite abilities. Since Jura can make the ground hard and Hoteye can make it soft it brings up the question which is stronger. Jura then boldly says that the one with the stronger belief will win, while Hoteye disagrees and says that the one with money will win.

They then both notice the pillar of light of Nirvana and Hoteye instantly says that they are going to be rich, and starts to waver between good and bad. This resulted in him having a change in personality like Sherry, he started to act more happy and says that he doesn't need money since love triumphs over all.

Their battle ends without a victor and Hoteye explains that he thought if he had money he would be able to locate his long lost younger brother. This made Jura and Hoteye form a close friendship.

Stellar Spirit Resolve: Lucy vs. Angel
As Natsu continues running he spots Gray lying in a river. He rushes toward him but is lured onto a raft and almost got killed before being saved by Lucy and the gang. They at first thought that Gray had turned evil due to Nirvana, but realize that he is an impostor. The impostor then poses as Lucy and lifts her shirt up which made the guys happy, and trouble Lucy. She later tells Sagittarius to shoot Hibiki, when Lucy forced dismissed Sagittarius and told Charle to take Wendy somewhere safe, the fake Lucy re-summoned Sagittarius to shoot Charle and Wendy out of the sky. Before she does, Angel shows up and the impostor is revealed to be Gemini, a celestial spirit of the ecliptic zodiac.

Realizing that everyone else is incapacitated Lucy has no choice but to fight Angel herself. She summon Aquarius to fight but Angel summons Scorpio, Aquarius's boyfriend, and neither chose to fight. She then scolds Lucy for not knowing the relations between spirits. Lucy then resorts to using her trump card Loke, but this time Angel summons Aries, Loke's friend. This greatly shocks Loke, Lucy, and Hibiki. Angel reveals that she killed Hibiki's former lover Karen, and took Aries from her. Lucy decided to force dismiss Loke instead of having him fight Aries, but Loke refused since they were summoned by different people and have to fight for their masters sake. Loke quickly gains the upper hand since Aries isn't a combat spirit so Angel, summons Caelum, to shoot through Aries just to hurt Loke and revealing that she can summon 2 spirits at a time. This greatly shocks Lucy since she mistreated her spirits so badly, Loke and Aries are forced to go back to the Spirit realm to heal but not before Aries being glad that Loke found a good master and Loke apologizing.

Lucy then summons Taurus but Angel re summons Gemini who poses as Lucy and uses Caeleum to take out Taurus. In an act of desperation, Lucy asks Angel to release Aries from her contract, since she deserved happiness. Angel agreed but only if Lucy surrenders her life, which she agrees to. Angel orders Gemini to kill her but Gemini remembers Lucy's love for celestial spirits and cries saying she can't kill her, greatly angering Angel. Later Hibiki grabs Lucy's neck and tells her that he is going to transfer a high level spell into her head. Lucy then enters a trance and recites an incitation that casts a spell powerful enough to greatly injure Angel. Lucy wakes up but doesn't realize what happens and then rushes toward Natsu. Angel then suddenly rises and tries one final attack to take down Lucy but fails. She then faints and remembers her prayer of fading into the sky like an angel, not in a river. Although her attack failed she did make the raft sail down a waterfall where she and Natsu both fall over.

Battle in the Sky: Natsu vs. Cobra
Erza arrives at where Jellal is and is surprised to learn that he has lost all his memory except for the name Erza. She then tells him everything he did in the past, which is deeply sad about since he can't believe what he has done. Later Lucy wakes up and finds her wounds treated and dressed in a different outfit. It is revealed that Natsu also got a new outfit by Virgo who passed through her own gate since Lucy is out of magic power. Later Sherry appears and tries to attack them, but she is stopped by Gray. She finally reverts back to herself when Lyon appears alive and well.

Elsewhere Wendy explains to Charle about who Jellal is and what he did for her. Back at Nirvana Cobra tries to take Nirvana but Jellal reveals that he has cast a spell on the dangerous machine and it will self destruct. Cobra starts to panic and Jellal also reveals that he plans to die with the deactivation code, with Erza trying to make him change his mind. Later Brain shows up and reveals that there is no reason to panic since he could easily stop the spell, since he was the one who taught it to Jellal. He then activates Nirvana's second stage and it turns into a walking machine.

Lucy, Gray, and Natsu are stuck on of its legs, but Natsu later falls off, luckily saved by Happy. Brain orders Cobra to kill them, and they take to the sky with their animal companions. Natsu originally had trouble fighting Cobra since he could hear and predict his moves and had good teamwork with his partner Cyberios. Natsu then tries to attack Cobra, without thinking about what he was going to do, originally missing the first few times but then finally managed to get a few attacks in. Cobra then decided to get serious and his hands turned into dragon claws, revealing his dragon slayer powers.

Natsu and Happy are surprised, but then learn that he is a new style dragon slayer like Laxus. He claims that since dragon's are extinct there is no way to learn dragon slayer magic, although Natsu said that Igneel is still alive. He later eats poison, provided by Cyberious and uses his Poison Dragon Roar, which affects both Natsu and Happy's movements. Without any other option, Natsu tells Happy to drop him and tricked Cobra into reading the wrong attack. Instead of doing his dragons roar he simply yelled really loudly to turn Cobra's super hearing against him and defeat him.

This surprised Brain that someone defeated an Oracion Seis with just their voice. Natsu and Happy land Nirvana with an injured Cobra approaching them to finish off Natsu. Before he could do anything he gets shot, and turns around to learn that Brain shot him. He then hears Brain saying that he doesn't need him anymore, and dies remembering his prayer of hearing the voice of his one friend Cyberios.

Sacred Ten against the Balam Alliance: Jura vs. Brain
Jura and Hoteye meet up with Lucy and Gray, who are both surprised to see Hoteye turning good. Hoteye explains that Nirvana was created sometime ago by a tribe who wanted peace and that the ruins on it are from its former village. They are later met by Midnight, who tries to attack them but Hoteye tells them to run, while he fights Midnight since every Oracion Seis should be equal in strength.

They later find Happy who tells them that Natsu got taken away by Brain. Charle and Wendy later arrive on Nirvana hoping to find Gerard but Charle notices that Nirvana is heading towards their guild, Cat Shelter. Jura and the others catch up to Brain, and learn of his plan to eliminate Cat Shelter, but don't know why. Jura then enters a battle with Brain and demonstrates his abilities and skills as one of the Ten Wizard Saints. Despite all of Brain's efforts he still can't land 1 attack on Jura and loses. He then slowly loses conscientiousness, with Hoteye winning his battle against Midnight. Before Brain fully loses conscientiousness, he remembers his prayer of, making sure that midnight, not lose. Midnight then wakes up seemingly healed, and defeats Hoteye in an instant, saying that he has now become a stronger mage than his father Brain. Hoteye then remembers his prayer of seeing his brother's face again.

Wendy and Charle later catches up to Lucy and the others, and tells them about what is happening, but they tell them that there is nothing to worry about anymore. But then they notice the machine still continuing to function so they realize that there is still 1 oracion Seis left. Wendy then heals Natsu but is surprised that he is still sick, so she casts troia, to make him feel better even if he is on a vehicle. Natsu then promises that he will save Wendy's guild no matter what.

The Sadist and the Justice: Erza vs. Midnight
Midnight continues his mission of eliminating all his father enemies. He eventually runs into Erza and Gerard and prepares to eliminate them both. Jellal tells Erza to stay back, while he fights Midnight, but loses due to being weakened by the self destruction spell he cast on himself.

Erza then step in and tries to attack Midnight, but learns that her sword doesn't reach him and went around him. Midnight then twists her armor hoping to choke her to death but she manages to remove it in time. Erza then enters her Heavens Wheel Armor hoping to overwhelm Midnight, with numbers but still doesn't work and almost gets chocked to death again, but then notices something when she throws a sword, but this time he chose to dodge it instead of it going around him. Thinking that he won, Midnight invites Jellal to become one of the Oracion Seis, but then Erza enters a new armor and says that she won't let that happen.

As Midnight and Erza continue their battle, Erza this time starts to gain the upper hand and tells Midnight about his magics two weakness. First, while his magic can distort anything, it doesn't work on humans. Second, when he distorts Erza's armor, he leaves himself open for an attack, which he gets overwhelmed by Erza's swords raining down on him. She also reveals that her armor, The Robe of Yuen, is an elastic armor so it doesn't affect her and adds a 3rd weakness.

Midnight then activates an illusion, where he turns into a giant monster and stabs both her and Gerard, but still fails since Erza's artificial eye lets her to see through his illusion. Midnight loses and remembers his prayer of falling asleep in a quiet place.

A New Enemy, A New Power
Natsu and his gang head to the throne room, while Wendy flies off to where Gerard is. When Natsu and his gang open the door, they spring a trap. The group managed to get away unharmed, but Jura got injured badly. Shortly after Brain's staff, Klondoa meets them. He explains to them that Nirvana was sealed away a long time ago by the Nirvit Tribe. The Nirvit tribe then left a guild to watch over Nirvana, and that guild was Cait Shelter, which is why the Brain planned to destroy it. He then enters a battle with Natsu and his friends, but then senses that all six of the Oracion Seis are now defeated meaning he will now show up.

Brain starts smiling and the lines on his face disappear. He then shows up where Natsu and his team are and changes his outfit and introduces himself as Zero. He then attacks them, and demonstrates his powers by easily breaking through Gray's Ice Shield and defeating Natsu with one hand. Then then knocks out Lucy, Happy, Gray, and Natsu then decides to resume his goal of destroying Cait Shelter, instead of finishing them off. He later crushes Klondoa and just as he fired Nirvana, Christina managed to shoot one of Nirvana's legs and miss the target.

Wendy and Charle manage to find Gerard and Erza, but Gerard doesn't remember Wendy. They later receive a transmission from Hibiki letting them know that they stopped Nirvana from firing at Cat Shelter, but they need their help in destroying it. He explains that at each of its six legs there is a chamber that houses a lacryma crystal which powers Nirvana. They need to destroy all six lacryma crystals at the same time and they can stop Nirvana, but that they only have 15 min till the next firing. Shortly after Zero, intercepts their message and lets them know that he will be waiting at one of the lacrimas to defend it. This poses a problem since they don't have 6 mages to take on all six crystals, and even if they did, they are all worn out to fight Zero who is at full strength. However, thanks to everyone's encouragement, Natsu, Gray, Lucy, and Happy regain consciousness and now set out to destroy the crystals. Before Hibiki's transmission times out he sends them a map and asks them to select a target. Natsu chooses 1, Gray chooses 2, Lucy chooses 3, Ichiya chooses 4, Erza chooses 5, and Gerard chooses 6.

Later at lacrima 1 Natsu finds Zero and gets ready to fight him and Gerard remembers Natsu's name and goes to his location. Since Wendy can't use her healing magic to heal Natsu, Gerard decides to do it himself while giving his target to Wendy and giving her inspiration to destroy it. Gerard arrives at Natsu's location saying he has his memories back and shoot fire at Natsu so he can heal. Despite hostilities due to the past Natsu at first refused to accept Gerards help, but when he defends Natsu from a blast by Zero, he gains Natsu's trust. He then gives him a golden flame telling him that he has confidence he can defeat Zero. Natsu accepts and eats the flame and then starts to grow dragon scales and activate his Dragon Force.

Natsu and Zero then continue their battle and are roughly even matched despite Natsu, not being able to fully control the Dragon Force. Meanwhile at Lacryma 3 Lucy arrives at the crystal but tells Happy, that she is out of magic power so she can't destroy the crystal, but even so she still wants to help Wendy. Later Gemini shows up and transforms into Lucy saying they will carry out her goal. As the time of firing draws near everyone else gets ready to destroy their crystals, while Natsu and Zero prepare to use their strongest spells. Zero at first seemed to gain the upper hand but Natsu then spouts golden flames and manages to defeat his spell and show him his powers as a true Dragon Slayer. Natsu then uses a new attack and manages to send Zero crashing into the crystal to destroy it, just as everybody else was destroying theirs leaving Zero defeated and saving Cat Shelter.

Final Goodbyes
Following the destruction of the lacryma crystals, Nirvana starts to fall apart and everyone tries to make it outside. Wendy and Charle and are saved by Jura. Natsu and Gerard were saved by Hoteye. While outside the gang meet Gerard for the first time and are surprised that he lost his memory, but since he helped them they consider him a friend. During a private conversation, Erza and Gerard reconcile and Erza tries to tell him something, but the army arrives and traps them in a barrier. They explain that the council is now restored and that they are here to capture certain people.

The army starts with Hoteye, of the Oracion Seis, for his past sins despite him being turned good by Nirvana. Jura tried to speak against them, but Hoteye decides to be arrested since he can never be rid of his sins even if he turned good. Before he gets taken away, Jura tell him that he will continue the search for his younger brother, and asks for his name. Hoteye says his name is Wally Buchanen and Erza instantly tells them that she knows him and that he is alive and well, traveling across the continent with his good friends. This makes Hoteye burst in tears, and realize that there is hope for those who believe in the light, and he is taken into custody with no regrets or worries.

Later the army tells them, that they are after another person even more dangerous that the Oracion Seis, Gerard. For his crime of infiltrating the council, firing the Antlion, and destroying the council he is arrested. Wendy tries to convince the army to change their mind but he refuses and says that he will either receive execution or life imprisonment. Erza looks on helplessly as her best friend is about to be taken away from her permanently just after reuniting. As Gerard was about to be taken away and the barrier lifted, Natsu instantly attacks the soldiers saying he won't allow Gerard to be taken away since he is now their ally and for the sake of Erza's happiness. Just as the rest of the gang followed Natsu and attacked, nearly getting arrested as a result, after making difficult decision Erza and tells them to stop and that they can take Gerard away. Before being taken into custody, Gerard manages to remember one final thing, Erza's scarlet hair. Following Hoteye and Gerard's arrest, the gang feels sad and leaves Erza alone. Erza then remembers back to her slavery days, and how she and her friends introduced their names. She tells them that her name is just Erza, this made everyone feel pity for her, but then Gerard notices Erza's scarlet hair and decides that her last name can be Scarlet. Erza instantly likes it and now has a full name, but then she bursts into massive tears and cried so much that she didn't notice the sunset which also happened to be scarlet red.

Arriving at Caitshelter, everyone gets new clothes to restore their torn up ones. They meet up with the people of cat shelter, and try to celebrate but then notice that the Guild master Roubaul is upset. Roubaul then explains that they are not the descendants of the Nirvit, they are the Nirvit tribe itself. He explains that 400 years ago he created Nirvana to stop wars and founded a village on the machine itself, which enjoyed a time of prosperity. However the darkness that they removed found its way to the Nirvit tribe and made the people kill everyone in cold blood, with only Roubaul managing to escape. He then seals away Nirvana since he can't destroy it himself, and settled in an abandoned town to watch over the machine until someone could destroy it. He swore and remained in solitude for some time, until Mystogan carrying an unconscious Wendy, arrived and asked him to watch over her. Wendy then woke up and asked where she was, since Mystogan told her that he was going to take her to a guild. Roubaul not wanting Wendy to feel sad said that this place was a guild, and used his magic to turn the wrecked town into a guild and create illusionary people. Now that the burden of Nirvana is destroyed, the guild members start to disappear and Roubaul tells wendy that she longer has to deal with having fake friends and that she can now move on and that she now has true friends. Not wanting her friends and master to leave her Wendy tries to run to Roubaul, but he disappears before she can reach him and she can only look on helplessly. Luckily Erza tells her that she knows its hard to have someone close disappear, and invites her back with them to Fairy Tail.
