Erza continued on with her training. She as well aware that as long as Zeref and the etherious were out there, they can't truly rest. Erza used her sword and slashed against the trees with all the power she had.

"I see you've been working hard." She looked over and saw Jellal was able to find her.

"Jellal, what are you doing here?" Erza asked.

"Looking for you." Jellal said. "Is everything okay? You've seemed stressed out lately."

"I'm fine." Erza said. "I'm just being prepared. I can't help, but shake this feeling that Zeref's endgame will be coming. I also just had a thought. You were connected to Mard Geer. Shouldn't you know the location of their hideout?"

"I do. They use this gigantic cube made of land and water with a castle at the top." Jellal said. "However, it's in some sort of hyperspace and the only way for a human to get inside is with immense magic power or for someone to let a human in from the inside."

"I see." Erza said as she seemed a little disappointed.

"It will be okay." Jellal said.

"I know. I just want this all to end." Erza said.

…

Kyoka

"Aw!" Kyoka screamed. She was in her private room and was smashing everything that was in her sight. "Why?! Why can't we ever defeat those rangers? They're just humans!"

"Kyoka!" Kyoka felt a cold shiver running down her spine as she her Zeref's voice. She turned to face him and dropped to one knee.

"Forgive me, Lord Zeref. Have I disturbed you?" Kyoka asked.

"No. You seem frustrated." Zeref said. "I take it that you are furious about the rangers succeeding all the time."

"Yes. I don't understand it. I never understand these humans." Kyoka said.

"Watch what you say, Kyoka. Keep in mind that even though I created you, I am still human." Zeref said.

"Lord Zeref, you're an exception." Kyoka said. "It's the humans like those rangers I don't understand. They protect people and for what? What gives them their strength?"

"That would be their hearts." Zeref said.

"'Their hearts?' If I had more power, I could show them what real strength is all about." Kyoka said.

"So you want more power?" Zeref said. "I might be able to grant you that power. However, you must be willing to accept that if you can't control these powers, they will destroy you before the rangers or you destroy the rangers."

"I am willing to pay the ultimate sacrifice if it is for your purposes my lord." Kyoka said.

"Very well." Zeref said as he held out his hand and dark power flowed from it and to Kyoka. The dark power entered her body and her body felt like it was being shredded and the pain was becoming unbearable.

"AAAAAARRRRGGGGHGHHGHG!"

…

Factory District

People were working around factories and even an innocent little girl walking her little wiener dog came by to visit her mother. However, a great day of work would become a great day for destruction. Kyoka was able embrace and control her new strength as she was walking towards the people.

"This will get the rangers to come out from hiding." Kyoka said. She unleashed her new power and explosions were happening around and people running scared.

…

Rangers' Base

All of them were alerted about danger happening in the city. All of them looked in the crystal ball and saw Kyoka causing destruction.

"Kyoka?! What does she want now?" Gray said.

"I don't know, but she must be stopped." Rogue said.

"All of you be careful. I sense there's something different about her." Mavis said.

…

Factory District

Kyoka had the people run into the factory for cover as she continued to terrorize the entire place.

"Hold it!" Kyoka knew who they were without even needing to turn around.

"Right on time." Kyoka said as she turned to speak to the rangers, with the original five in their Mystic Mode. "I'm so glad you're here. This time, I will finish you off once and for all."

"Don't kid yourself. You haven't been able to beat us before." Erza said.

"And there's no way you're going to beat us this time." Natsu said.

"I beg to differ." Kyoka said. "Allow me to show you my new found strength!" She unleashed flashes of green lightning from her claws and blasted all of them with great power that they were knocked down form a single attack.

"Whoa! What was that?" Sting said.

"She's even more powerful than she's ever been before." Jellal said.

"That's right. Lord Zeref has granted me new strength." Kyoka said. "It's just enough to destroy all of you for good." She slowly advance to them. "You're all right where you belong. You humans are beneath us etherious and it's time you learned your place. Beg me for mercy and bow to your superior race."

"We'll never bow to you!" Erza said as she got up and attacked. She swung her staff, but Kyoka stepped to the side and slashed against her back and smacked her over to the entrance.

"Erza!" Lucy called out.

"We've got to help her!" Natsu said as all of them got back on their feet and tried to help her. However, tartaros soldiers showed up and stopped the rangers from going any further.

"Who said you two could come?" Kyoka said as she saw Tempester and Keyes arrived.

"You are not the only one who wants to face the rangers." Keyes said.

"Today is when they shall be destroyed and it won't by you alone." Tempester said.

"Very well." Kyoka said as she found this not even worth arguing. "Hold the rest of them off. Yellow and I have a score to settle." Kyoka went to face Erza and left the others to deal with the other rangers. Erza stood up to face Kyoka. "Still think you can win?"

"I don't. I know I can." Erza said. "Your evil will never win!" She shot out a blast of wind, but Kyoka was able to deflect it.

"You have no chance!" Kyoka said and attacked Erza and slashed with great power that sent her flying into the building and put innocent people in harm's way. "How fitting. You can fall with the rest of your kind." Erza looked back and saw innocent people in trouble.

"You can't." Erza said.

"I think I will." Kyoka said as she built up power and shot it all out. Erza stepped forward and tried to block the attack to protect the people. The power was building up and caused an explosion that the others heard.

"Erza!" Natsu called out as he wanted to go help her, but Tempester stood in his way as he grabbed him by the shoulders and shoved him back.

"You're not going anywhere." Tempester said.

"Move it!" Natsu said as he shot out some fire, but Tempester jumped over and tackled Natsu down. Sting climbed up a metal beam over some tartaro soldiers. He jumped off and fired them with his blaster. Rogue took a piece of scrap metal and used it as shield to block a spear and knock the soldier back. Rogue flipped back and fired his blaster. Lucy kicked one and back and slammed her staff against it. She jumped onto a metal beam and fired off blasts of pink light.

"Chill out." Gray said as he froze a few. He avoided a club and jumped up to get one in a scissor hold and knock it down. Gajeel did some back flips and ended with a split kick.

"Check out this magic trick." Gajeel said as he used his magic and launched some of the metal and hit them all with it. Jellal was fighting off against Keyes as the two of them clashed their weapons together.

"Get out of the way." Jellal said.

"I think not." Keyes said. "With such power at her command, Yellow shall meet her end by Kyoka." Erza was knocked down by the explosion as the workers ran off. However, the girl and her mother were pinned down by debris.

"Hang on." Erza said as she tried to get up to help those people, but Kyoka kicked her further in.

"Why bother? You should be more concerned about yourself." Kyoka said. "There's something I don't understand about you rangers. Why do you protect people?"

"Why would you ask something like that?" Erza asked.

"You protect people and for what?" Kyoka asked. "What have any of them have ever done for you? All you humans do is look out for yourself? So why is it so important for you to protect people that you don't even know?"

"You don't get it." Erza said. "We don't do it for any sort of benefit. We do it because it's right. We feel that in our hearts and that is where our power comes from to protect people."

"Oh please. More of this heart talk?" Kyoka said. "The heart is nothing more than an organ that keeps you alive. All that other stuff you humans believe the heart grants is nothing more than you being delusional."

"You're wrong." Erza said.

"Just look at right now. All those other humans ran off and left their own to perish." Kyoka said.

"Hang on. We're coming!" Both of them looked back and saw the workers come back with tools to help. They went for the child and the woman and were able to save them.

"Are you alright?"

"Yes, thank you."

"Wait. Where's Louie?" The girl said.

"I got him." A worker was able to find the dog and dig him out. When it mattered most, humans came and worked together to help their own kind.

"Good work. Now get going." Erza said and all of them ran out. That meant Erza can completely focus on Kyoka. "See that, Kyoka? You've underestimated us 's the power of the human heart, but I guess a heartless monster like you could never understand."

"Enough of this!" Kyoka said and went to attack. She swung her claw, but Erza deflected it and kicked her in the gut. Erza held her staff against Kyoka and used her wind power to blow her back.

"This time, you're finished!" Erza said as she charged in and attacked. She bash her staff against Kyoka, but Kyoka pushed it away. She was about to strike Erza down, but Erza pulled out her sword and blocked the attack. However, Kyoka lifted her leg and kicked Erza back.

"Perish!" Kyoka shouted as she unleashed her power right at Erza and caused another explosion.

"White Shadow Slash!" Sting and Rogue combined their powers and finished off the soldiers. Gajeel, Lucy, and Gray slammed their staffs against Keyes while Jellal and Natsu slashed against Tempester.

"Had enough?" Lucy asked.

"We don't have all day to beat you guys to the ground." Sting said.

"You might be strong, but the day will come when you rangers fall." Keyes said. "From the sounds of things, your friend already has."

"If you think that, you really don't know Erza that well." Jellal said. Kyoka was walking away as she believed she won.

"Hold it!" Erza ran through the flames with both her weapons for she refused to surrender.

"Why won't you go down?!" Kyoka said.

"Not until you drop first!" Erza said.

"Charging right in? What a stupid way to sacrifice yourself!" Kyoka said as she unleashed more of her power, but Erza fought through. Erza might have been forced out of ranger form, but she still held on her weapons and kept going. "What?!"

"You're through, Kyoka!" Erza shouted as she reached Kyoka and slashed her staff, that held magic wind power, against Kyoka and then her sword. She finished it with mighty scream and a cross slash against her. Kyoka couldn't withstood that power and she didn't how this could have happened. She wondered if this is the power of the human heart. Kyoka fell backwards and she met her end as she was faced with a fiery explosion. "Goodbye, Kyoka." It did not go unnoticed by the others.

"It can't be! Kyoka has been destroyed as well?!" Tempester said.

"Not for long." Keyes said as he was about to use his power to make Kyoka be revived and grow.

"Not this time!" Natsu said as she shot out some fireballs and blasted Keyes to stop him. "Kyoka's gone and she's not coming back. You might as well run while you can." Natsu said.

"Keyes, let's go. Kyoka's demise shall not be in vain." Tempester said. Keyes agreed and the two of them left. All of them looked over and saw Erza, but she was stumbling for she was badly injured.

"Erza!" Jellal called out as he raced over to her and catch her from falling. "Erza, are you okay?"

"I don't know. Everything's starting to go dark." Erza said and she passed out.

…

Rangers' Base

Erza had some bandages wrapped around her. After she was able to wake up. They were celebrating over their big win with Kyoka gone forever.

"Here you go." Jellal said as she handed Erza some juice.

"Thank you." Erza said.

"You should be quite proud of yourself." Lucy said.

"No kidding. All that power Kyoka had and you still managed to take her down." Gajeel said.

"Remind me never to make her mad." Sting whispered to Rogue.

"Thanks guys." Erza said. "Kyoka underestimated us and that was her downfall. The same will be between Tempester, Keyes, and even Zeref. They don't understand how strong the human heart can be. That's why we'll prevail."

"You got that right." Natsu said. "They can try whatever they want, but we're not going down." All of them raised their glasses and tapped them together for their declaration that humans will triumph over the etherious.
