Lucy and Cana, Natsu and Happy, Gray and Loke, Elfman and Evergreen, also Gajeel and Levy passed the first phase of the S-Class Trial. During the second phase, a dark guild called Grimoire Heart made its way to Tenrou Island in order to accomplish their goal of resurrecting the Black Mage, Zeref. Their forces directly interfered with Fairy Tail's ongoing S-Class Trial on the island. Leora was knocked unconscious by the combining attacks from the strongest team of Grimoire Heart - the Seven Kin of Purgatory. Later, Fairy Tail successfully defeated all the members of the team. The Exceeds, Happy, Carla and Panther Lily decided to scan Grimoire Heart's ship while Team Natsu and Wendy proceeded to battle Hades, the master of Grimoire Heart. They battled him with everything they have, even creating a Unison Raid. At some point, they appeared victorious, but Hades soon recovered, barely affected by all their attacks. Hades revealed to them that he was the Second Master of Fairy Tail, but Natsu did not believe him. He was easily immobilize the group with his Amaterasu, Chain Magic and Bullet Magic.
Just as Hades was about to finish Natsu off, thunder crashed through the airship and Laxus appeared. Laxus, hearing Natsu said that Hades was his grandfather's enemy, proceeded to head-butt him. Laxus and Hades soon fought, with Laxus starting off strong. The fairies were astonished by Laxus' strength as he continuously delivered spells and dodged Hades' attacks. However, Hades' last attack had weakened him. He attempted to strike Laxus down with an energy beam, and just as it connected, Laxus managed to transfer his powers of lightning to Natsu, though it drained him greatly. The others were astonished that the lightning and fire have fused together in Natsu's body. Laxus asked Natsu to pay Hades back for the pain he caused. Natsu, completely revived and brimming with lighting power, charged after Hades with multiple melee attacks, overpowering Hades, with Lightning Fire Dragon's Roar as a finisher. For a moment, they believed he had been defeated. But they were wrong when Hades got back up.
"You're quite some amazing youngsters. That damn Makarov... He raised some incredible brats..." said Hades. "No way..." said Wendy, shaking. "I don't know how many decades it's been since I've taken this much damage... It would be simple to finish things off as they are right now. But I want to thank you properly for entertaining me." said Hades. "That's impossible!" yelled Gray, shocked. "That attack didn't have any effect on him at all?!" yelled Erza.
Master Hades pulled off his right eye patch. "The Devil's Eye... Awakening! I'm going to show you something quite remarkable. The Abyss of Magic. This domain of magic is far beyond any of your wildest imaginations." said Hades as his appearance changed dramatically. The others all shook in fear. "This is your end. Fairy Tail." said Hades.
"Not on my watch!" The others all turned around to see Leora with her eyes open. "Another one of Makarov's brats." said Hades. "No matter. You little ones cannot pass into the great world of magic. You lack the resolve to step into the abyssal deem. From the chapter 4, scripture 12 of the book of Zeref... Hidden Magic... The Punishers of Heaven: "Nemesis"!" Demons were summoned from the rock around Hades and everyone else. "With the power of he Abyss. I can spawn demons from even the lowliest of rocks. They are at once the dancing children of demons, and judges of heaven. This is Hidden Magic." said Hades. Everyone except Leora was afraid. There was only rage in her eyes.
"Did you say Zeref?" asked Leora. Lightning and fire started to surround her entire body. "Only I am allowed to use his magic!" yelled Leora as she used lightning to transport herself around Hades, defeating all the demons in an instant with her Steel Fire Dragon's Claw attack. Everyone was shocked. "Impossible!" yelled Hades, unable to believe what just happened. "I won't allow you to harm anyone even if you're the second master!" yelled Leora. "Natsu, remember what Gildarts taught you?"
Natsu's eyes widen as he remembered what he had learnt. "Fear isn't "evil". It only allows us to learn our own weaknesses. When we learn our weakness... People can grow stronger and kinder. We learned our own weakness right now. So what do we do next?" asked Natsu as he slowly got back on his feet. "Grow stronger! Face them head on! When we're all alone, it might be too frightening to bear... But we're all right beside each other. We've got our comrades right here! There's nothing to fear! We're not alone!" The other all slowly rose up from the ground after hearing Natsu's speech. "Something gonna happen. You guys wait a while. Don't worry. I won't finish him off." said Leora as she charged forward to have a one-one-one combat with Hades.
Suddenly, something did happen. Fairy Tail's magic power had returned. "Fairy Tail will win!" yelled Leora as she swung her fist towards Hades. "NO!" yelled master Hades as he sent Leora flying to the side. "Until those of you that follow this path of magic finally reach its peak... The devil will not sleep!" Laxus got up and hit Hades in the face. "Go! Fairy Tail!" yelled Laxus.
"Open! Tenth Zodiac Gate! Capricorn!" yelled Lucy as Capricorn was summoned to attack Hades. "Sky Dragon's Wing Attack!" "Ice Bringer!" Tenrin-Pentagram sword!" "Dragon Slayer's Secret Art Revision! Crimson Lotus: Exploding Lightning Blade!" yelled Natsu as he gave the last blow.
Master Hades was defeated. Fairy Tail won. "This is our guild!" yelled Natsu victoriously. On the other hand, Happy, Carla and Panther Lily were being chased the lesser mages of Grimoire Heart, but Natsu and the others were all out of magic power. "Lightning Dragon's Barrier!" yelled Leora as lightning surrounding the lesser mages, making them halt.
"Hold it right there!" yelled Master Makarov as he arrived with the rest of the Fairy Tail members. The lesser mages were shocked to see there were still more Fairy Tail members and that their master, Hades was defeated. "Get off this island immediately." ordered master Makarov. Leora released her spell for them to get off the island. With that last spell, she got up from the ground and left while everyone was cheering happily.
"It's good to have you back." said master Makarov as he walked over to Laxus. "Did you think I was gonna say something like that?! You shit-for-brains! What were you thinking stepping foot onto Tenrou Island while you were still being exiled?!" "Shut up, old man." said Laxus. "L-Laxus..." said Freed. Then, all three of the Thunder God Tribe crashed onto Laxus. "Gwah! Get off! Where's Leora?!" asked Laxus as he looked around. The others all looked around too but she was no where in sight. "Her scent is coming from the direction of the base." said Gajeel. "Let's go there right now!" said Levy as she ran towards the direction of the base. Laxus used his dragon smell to find Leora and teleport to her with his lightning.
Leora had dispelled her vision spell when she was heading back to the base. When she caught a whiff of Laxus's scent, she immediately cast the spell again. A flash of lightning appeared in front of her. Laxus was standing there in front of her. "Laxus!" yelled Leora happily as she jumped into Laxus's embrace. "I missed you." "I missed you too, Leora." said Laxus. "And I'm sorry for lying to you." Leora shook her head. "That's doesn't matter anymore. Help me do my bandages. The others are gonna get here soon." said Leora. "Okay." said Laxus as he grabbed a roll of bandage to begin bandaging Leora up.
The others came running back just as Laxus was finished tying the bandages. Everyone was surprised to see Leora looking at them without her bandanna covering her eyes. Leora could see some of them got tears in their eyes. "Now's not the time to cry, guys. You all need to get bandaged." said Leora. "We're fine, Leora-chan." said Lucy. "Besides, you were attack by all of them at the same time. You should rest." said Levy. "I'm fine. Go spend some time with Freed and the others, Laxus. I'll catch up to you later." said Leora. "You sure?" asked Laxus. "Yes. Now go. I'm gonna take care of Gajeel-nii and the others' injuries." said Leora as she pushed Laxus towards the Thunder God Tribe. "I'll see ya later, Leora." said Laxus as he went into the forest along with the Thunder God Tribe.
"Now then, let's start bandaging!" yelled Leora as she held out some bandages too see who to bandage first. But before she could do so, she was hugged tightly by Lucy and Levy. "Leo-chan, when did you find the cure?" asked Levy. "I'm so glad that you can see again!" yelled Lucy, tears flowing down her cheeks. "It's only a temporary spell. I've got to dispel it after a while, like now." said Leora as she dispelled her eye spell. "Gotta call Leo-nii out. My bandanna's torn now." Leora opened a portal for Loke to pass through. "Got a new one right here for you. This time it's from Gemi and Mini." said Loke as he held out an orange and black bandanna to Leora and took the torn one away from her.
"Thanks, Leo-nii. Tell Gemi and Mini that I said thanks to them too. Also, help me tell Capricorn-nii "Welcome back!" too." said Leora as she held onto her new bandanna. "Will do. Take care of yourself, Leora. Goodbye everyone. Goodbye Lucy~" said Loke before he went back to the Celestial Spirit World. Suddenly, Leora felt a strong presence coming Fairy Tail's way. "I here trade my blood for the sight of my eyes. Oculus Opticia!" chanted Leora quickly. She noticed Natsu, Gajeel and Wendy all tensed up too. Leora tied her bandanna onto her head and muttered: "A dragon's coming..."
Just then a loud roar was heard. "What's that?!" yelled Gray. "It's damn loud!" yelled Elfman as he covered his ears. "The cry of a dragon..." said Wendy. "Eh?!" asked Levy shocked. "A dragon?!" asked Lisanna. Everyone who went into the forest quickly came back to the guild. "It's so loud!" yelled Happy as he covered his ears with both his hands. "He must be from back then..." said Gildarts as he squeezed his left arm, remembering the past. "Over there!" yelled Panther Lily as he pointed to the sky.
A black dragon with blue markings was flying in the sky. Everyone was shocked. "What is that?!" yelled Gray. "It's huge!" yelled Elfman. "That is a..." said Juvia. "Dragon?!" yelled Bickslow, finishing Juvia's sentence. "What the heck is that..." said Lucy worriedly. "Is that for real?" asked Gajeel shivering. "A real-life dragon..." said Wendy, quivering in fear. "I knew it. Dragons really do still exist." said Natsu. "He looks familiar..." muttered Leora with her brows furrowed.
"The Black Dragon of Apocalypse... Acnologia." said master Makarov.
"You over there! You know where Igneel is right now, don't you?! And Grandine and Metalicana too!" yelled Natsu in rage. "Knock it off, Natsu!" ordered Gildarts. Acnologia came flying down and crashed onto the ground. It let out a loud roar, scaring everyone. It then jumped out and charged towards everyone. The ground around it was shattered. "Is this for real?!" asked Elfman, shocked. "Look at the destruction it caused!" yelled Levy. "What the hell is that?! Where did it come from?!" yelled Cana, shocked. "Hurry, to the ship!" ordered Gildarts.
"Run! Everyone, we're all going back together! To Fairy Tail!" yelled Erza. "Wendy! You can talk to dragons, can't you?! Can't you do something about this?!" asked Carla while running. "I can't talk to them! Dragons all have very high level of intelligence." explained Wendy. "That dragon should definitely be able to understand words!" yelled Carla.
Everyone was running to the ship except for master Makarov. "Gramps!" yelled Leora. "Old man!" yelled Natsu. "Master!" yelled Happy. "Run, get to the ship."
