"Mavis? Are you okay?" Pixi asked as Mavis just sat in the center of the room.

"She's here." Mavis said as she awaited the arrival of someone. Lucy opened the door and entered the room. After defeating the latest villain, Lucy got a hold of a book that contains the secrets of the miraculous. Stella brought her to the one person that could help. "Hello, Celestria."

"I'm sorry, Master Mavis." Stella said as she actually came out of hiding. "I know you never wanted me to bring her here, but I thought it was finally time." Lucy had a look around the place as she remembered being here before.

"I met you before." Lucy said. "You healed Stella when she was sick. I also met you that day I got my miraculous. Who are you?"

"My name is Mavis Vermillion. I'm the last guardian of the miraculous." Mavis said.

"It's a pleasure to meet you." Pixi said with Lucy noticing her. "My name is Pixi. I'm Master Mavis' kwami." Lucy was amazed by all this. She was meeting the very person that gave her the miraculous. "Let me tell you a story." Mavis stood up and walked over to a record player that had a hidden set of buttons. When she input the code, it opened a secret compartment and revealed an octagonal box. "We guardians have watched over the miraculous for hundreds of years. I was left at the doorsteps of the temple where they took me in and trained me to be a guardian." She opened up the box and showed all the miraculous. A few were on top and others came out from the sides. "Some time ago, I made a mistake and all was lost. As a result, two miraculous were lost. The black miraculous and the unicorn miraculous. The miraculous that go in the top half are the more powerful miraculous, including yours and Salamondra's. There's also the knight miraculous, fairy miraculous, and the ice miraculous."

"What about the ones in the side?" Lucy asked.

"These miraculous, two each, represent the elements. One's an ordinary animal, another would be a mythical creature." Mavis said as she listed them. "The tiger and the phoenix represent fire. The shark and the mermaid represent water. The falcon and the harpy represent wind. The lion and the minotaur represent earth. The rabbit and the Pegasus represent light. Finally, the bat and the werewolf represent darkness."

"Amazing..." Lucy said as she found all of this incredible. It all did seem impressive, but she got serious when she remembered why she was here. "Anyway, I came here because Stella said you can help with this." She showed the grimoire with Mavis amazed that she had it.

"I thought this was lost." Mavis said as she took the book and looked through it. "This books holds the secrets of the miraculous. The ones who wrote it were very thorough to ensure this information never falls into the wrong hands. During my training, I wasn't allowed to read this. I never thought I get the chance." This is beneficial to both Lucy and Mavis. The secrets of the miraculous could be revealed.

...

Natsu

While Lucy was having a great time, Natsu was having a lousy one. Zeref showed him security footage from when Natsu took the book in the secret safe behind the portrait of their parents. As he hit pause on Invel's tablet, he wasn't happy.

"Why did you take the book, Natsu?" Zeref asked.

"I'm sorry. I was looking through that stuff you kept behind the portrait of our parents." Natsu said. "You never told me about it. Anyway, I took it and..."

"You lost it!" Zeref said. "This is a serious breach of my privacy and my trust, Natsu! That book meant a lot of to me!"

"I'm sorry. I'll just get you another one." Natsu said.

"You can't! There's not another like it in the world!" Zeref said to make Natsu feel even more guilty. "This is unacceptable, Natsu. You won't be returning to school. Invel will homeschool you."

"What?!" Natsu said as that was the last thing he wanted to happen. "Zeref, you can't!" His pleads just went on deaf ears. Zeref just left Natsu's room with Invel and Jacob following and shutting the door. Now Natsu is feeling like a prisoner in his own home. A feeling he never wanted to have again.

"Jacob, wait here in case Natsu needs something." Zeref said.

"Yes, sir." Jacob said as he and Invel went down the stairs.

"What will you do now without the book?" Invel asked.

"Leave me. I need some privacy." Zeref said as he stepped inside his atelier with Invel respecting his wishes. As for Natsu, he was feeling trapped like all prisoners.

"Good thing kwamis don't show up on camera. That would have been ugly." Igneel said. He was trying to see the bright side of a situation, but Natsu appeared to be in no mood for anything. "Come on, Natsu. At least you won't have boring homework to deal with anymore.

"That's not what I want, Igneel. I feel bad I lost that book." Natsu claimed. "I didn't know it was so important to him. What am I going to do now?" With Natsu feeling trapped and his own brother furious with him, he just doesn't see how things could get worse for him. It always gets worse.

...

Mavis and Lucy

Mavis and Lucy looked through the grimoire. Mavis was trying to read as much about it as she could while being fascinated by it at the same.

"So, since you're the guardian, but never really finished your training, can you really read it?" Lucy asked.

"A little, but I'll need time to decipher all of it." Mavis said. "I always believed that whoever had this book might also have the unicorn and black miraculous."

"Wait. Are you saying whoever owns this book could be Black Wizard?!" Lucy said.

"Possibly. Where did you find this book?" Mavis said. That question had Lucy's mind spiraling. Since she got the book from Natsu, the boy she loves, she's afraid he might be Black Wizard.

"I...just found it sitting on a bench." Lucy lied. "When Stella told me how important it was, I just knew I had to take it."

"You didn't see who had it? Pity. This could have helped us find Black Wizard." Mavis said.

"Well... I could go back and see if I could find anything." Lucy said as she wanted to help in some way.

"Be careful, Lucy." Mavis warned. "We can't allow Black Wizard to know about me. It's possible that you could end up facing him in person." A terrifying thought since Black Wizard has controlled everything, but Lucy knows he'll have to face him eventually.

"I'll be very careful." Lucy said. She got a hold of Stella and hurried out of there.

"Why did you lie to Master Mavis?" Stella asked.

"Tell her I got the book from Natsu? No way." Lucy said. "There's no way Natsu could be Black Wizard. Oh... What if he is? What do I do if he is? I'll have to fight him?" Lucy didn't like any of those ideas. "I've got to find the truth."

"Do you even know where he is?" Stella questioned.

"I know his schedule. He must be at the school by now." Lucy said.

...

The School

Lucy hurried back to the school to find Natsu. She was able to make it, but she didn't see him anywhere. This was unusual for she was certain Natsu would be at the school by now. She didn't quite get was going on, but had to stop when she heard crying coming from her classroom. Lucy hurried up there and saw everyone gathered with Taylor crying.

"What's going on?" Lucy questioned.

"Natsu's not coming back to school...EVER!" Taylor cried.

"What? Why?" Lucy asked.

"His older brother is mad at him." Gray claimed. "Something about loosing this book that's super important to him."

"His brother's book?!" Lucy said as she found that really interesting. She tried leaving, but Gray was curious as to why she wasn't freaking out.

"Where are you going? You just got here?" Gray asked.

"I'm...going to think. Maybe if we find that book or come up with a plan, we'll get Natsu back." Lucy lied and hurried out of there. She went straight for the bathroom to talk to Stella. "Did you hear that? If Natsu took it from his brother, he can't be Black Wizard! I knew it! Natsu's too perfect to be a villain." She said in a lovely daze.

"Lucy, focus!" Stella said to snap her out of it. "If the book belongs to his brother, his brother must be Black Wizard!"

"Zeref Dragneel?" Lucy questioned. She thought it over. "He is very mysterious and never leaves home. No one knows much about him. He's cold and aloof even to his own brother. It's a theory, but better than nothing. Stella, Twinkle!" Stella was pulled into her earrings and allowed her to become Celestria. When she transformed, she went up to the roof and used her whip to give Salamondra a call.

"You've reached the hot stuff of Paris. Leave a message."

"Salamondra, meet me at Francois Highschool. I think I know who Black Wizard is." Celestria said and hoped he shows soon.

...

Dragneel Mansion

Natsu tried playing his piano lessons, but Natsu couldn't focus because of his misery. He wishes he could just do something to cheer up his brother. As for Zeref, he held out a locket that held pictures of him and his family. Loosing that locket as his mind all turned around. He couldn't take it anymore and let his anger take control of him. He took everything in the room and just started smashing it. Natsu could hear the smashing and got worried for his brother.

"What was that?!" Natsu called as he ran out of his room, past Jacob, and to the noise. Invel stood in the way and wouldn't let him through.

"Your brother wishes to be alone." Invel said, but all the smashing wasn't helping him.

"Doesn't sound like he should be." Natsu said.

"Shouldn't Natsu be practicing on the piano?" Invel said.

"Come on, lad." Jacob said as he had Natsu go back up the stairs, but Natsu was really worried about his brother.

...

Black Wizard

"A man that feels betrayed by his brother and loosing something that's greatly important to him. Perfect for my etherious." Black Wizard claimed. He took an etherious and filled it his dark power. He released it, but something was different. It didn't fly out this time. "Darkness, Fade!" Black Wizard relinquished his powers with his kwami, Anka, emerging out of the miraculous.

"Why is the etherious still here?" Anka asked. Black Wizard reached for the miraculous at the collar of his shirt. It turns out the theory is true as Black Wizard is truly Zeref.

"I need to become someone else." Zeref said as he took off his miraculous. "Anka, I renounce you." Anka was pulled into the miraculous and placed it in a small box. "For now, at least." Once he had the miraculous away, he reached for the pendent under his shirt. Once he removed it, he held it out. "Come, etherious! Evilize me!" The etherious flew to Zeref's locket and went inside. Zeref was transformed by his own power. He transformed with all his clothes turning white, as did his hair, and wings made out of light were formed with his locket around his neck.

"From now on, I am Spriggan! I have lost something of most importance, but my locket will help me make sure I won't lose anything again, and maybe a couple miraculous."

...

Natsu

"My brother is mad with me. He won't forgive me unless I find that book." Natsu said as he set a recording of piano music. He knows he needs to find that book to get out. "Igneel, Fire Up!" Igneel was pulled into his ring and he became Salamondra. He was just about to go out the window when he saw he had a message from Celestria.

"Salamondra, meet me at Francois Highschool. I think I know who Black Wizard is."

"Wow! The book can wait a little longer, I suppose." Salamondra said and hurried off to the school, just missing something important.

"Invel..." Invel turned to the door, but it was kicked down by Spriggan.

"Sir?" Invel questioned.

"Not quite." Spriggan said. He opened his locket and it fired a beam of light that absorbed Invel upon contact.

"What the blooming...?!" Jacob shouted before he was absorbed as well. Spriggan made his way up the steps and to his brother's room.

"Natsu... I want to show you something." Spriggan said as he knocked on the door. When Natsu didn't answer, he let himself and saw his brother was gone. When he saw the recording, he knocked it away and was really mad now. Spriggan unleashed his terror as he began to seal people, objects, even the Eiffel Tower inside his locket. It's only a matter of time until he gets his hands on the miraculous.

...

Celestria

Celestria kept waiting for Salamondra, but she was getting frustrated when he never showed up.

"Salamondra, where are you?!" Celestria yelled into her whip. That was when Salamondra showed up.

"Sorry to keep you waiting." Salamondra said and got her attention. "I just recently transformed and got your message, my little star. Who's the prime suspect?"

"The fashion star: Zeref Dragneel." Celestria said. Salamondra almost lost his balance when he heard that.

"Wha... What makes you think it's him?" Salamondra asked as he didn't want to believe it's his own brother.

"Nothing concrete, but I have some theories." Celestria said. "He's a mysterious man that never leaves his home. Plus, look at some of his designs." She said as she used her whip to show images. "The color black is in almost all of them. Look at his logo, too." She showed the logo and Salamondra couldn't believe it.

"A set of black wings?!" Salamondra said. When he thinks about it, he has seen black and wing-patterns around his house. He couldn't believe that his own brother might be their worst enemy.

"Are you okay?" Celestria asked as she noticed something was bothering him, but he just turned his back to her.

"Let's go find the truth." Salamondra said. He just took off with Celestria following him. While they were on their way, Spriggan was already aware of their move.

"My plan is working perfectly." Spriggan said. All that was left for him was to catch them.

...

Dragneel Mansion

The two of them hurried over to the mansion to find anything. They entered Zeref's office, but they saw the whole place was a mess.

"Whoa! What happened here? Did someone throw a tantrum?" Celestria questioned. Salamondra looked around and was filled with more misery. How many secrets does Zeref keep? Is he really just criminally insane? "Are you sure you're okay?"

"Yeah..." Salamondra said, but it didn't sound too sincere. That was when they heard a noise coming from upstairs. Wanting to know the truth, Salamondra didn't wait around any longer and hurried off with Celestria following. "Where's Zeref Dragneel?!"

"There is no more Zeref. There is only Spriggan!" Spriggan claimed as he appeared on the stairs. He opened his locket and fired the beams at him, but the both of them moved out of the way and saw the door was absorbed.

"Don't get hit by that light!" Celestria said. Spriggan tried a more direct approach as he jumped off the stairs and attacked them directly he appeared capable of fighting them off. Salamondra tried his staff against him, but Spriggan caught it. Spriggan kicked him back and tried capturing him, but Salamondra moved out of the way. Celestria tossed her whip and got it his around arm. She tried throwing him to the wall, but he jumped off it and kicked her back.

"Move!" Salamondra said. Spriggan tried capturing her, but Salamondra grabbed her and moved up the stairs. They ran around up there as Spriggan tried shooting his beams at him. They kept going until they ducked down. "Wait a minute. If Zeref Dragneel was etheriouized, he can't be Black Wizard!" He said with much joy.

"You think Zeref Dragneel being etheriouized is a good thing?" Celestria questioned. Spriggan jumped up to them and landed on the railing. They both moved away from his beam. Salamondra swung his staff and knocked him off the railing. Salamondra jumped down and attacked again, but Spriggan avoided it and kicked him into the dining hall. Celestria swung down to regroup with him. Spriggan chased after them, but lost sight of them.

"Over here!" Salamondra called as he tossed his staff at him, but Spriggan caught it and sealed it in his locket. "Hey!" Celestria acted fast as she used her whip on a chair and tossed it at Spriggan. It hit him and allowed them to run for cover behind the stairs.

"The etherious must be in his locket." Celestria said.

"But how do we get close enough to grab it?" Salamondra questioned.

"We still have something that could help." Celestria said as there was still one trick. "Open the Celestial Gate!" She opened the gate and formed peddle. "A Libra peddle?"

"There's no way you ride far enough from me." Spriggan said as he was right in front of them. He fired another beam at them, but they both jumped up and took cover in Natsu's room. They tried barricading the door to keep him out until they can figure something out.

"Wait. Where's his brother? This is his room." Celestria said.

"Maybe he got captured...?" Salamondra claimed.

"You really think he imprison his own brother?!" Celestria said.

"You don't know the half of it." Salamondra said under his breath.

"You can't hide from me!" Spriggan said as he was working on getting in. They need to do something fast. Celestria looked to see what she can use her celestial item with. She spotted Salamondra's belt, Natsu's shelf full of video games, and his foosball table.

"I got it!" Celestria said as he took his belt. "Use your Dragon Fire on those shelves. We're making a conveyer belt." He didn't get it, but he just went with it.

"Dragon Fire!" Salamondra used his power and jumped up to the shelves to burn them to ashes. Celestria took the belt and used it to help connect the rods of the table and the peddle. Just as they got ready, Spriggan was able to break inside by sealing away the barricade.

"Before I seal you away, how about you just give me your miraculous for Black Wizard." Spriggan said as he entered, but that was when he saw what they built. Celestria started turning the peddle as fast as she could as Salamondra dropped all the games. Their crafted conveyer belt launched all the games and smashed against Spriggan. Flying across the room and hitting against him. One flew straight across and smashed against Spriggan's locket with it breaking and the ehterious flying out.

"No more evildoing for you, little etherious." Celestria activated her whip and twirled it around. "Time to de-evillize!" She tossed it at the etherious and got a hold of it. "Gotcha! Bye-Bye, little guy." She purified it and released it. "Miraculous Starlight!" She tossed the peddle in the air and it burst into streams of stars with everything being fixed and all those who were imprisoned were free. Zeref also turned back and acted like nothing happened.

"Pound it?" Celestria asked Salamondra, but she ignored him and ran to Zeref.

"Are you okay?" Salamondra asked.

"I think so." Zeref said. "Wait. Where's Natsu?! Where's my brother?!"

"I'm sure he's fine. He's just somewhere else." Salamondra said.

"Salamondra's right. If he was in danger, he would have been brought back here." Celestria said.

"I just hope nothing has happened to him. My brother means everything to me." Zeref said.

"He'll probably be back soon. We should get going, Salamondra." Celestria said.

"Yeah. See you later, Dragneel." Salamondra said with him and Celestria leaving and never suspected a thing.

"Sooner than you think." Zeref said as he hasn't been defeated yet.

...

Mavis

"So, I thought Zeref Dragneel might have been Black Wizard, but he can't be since he was etheriouized." Lucy said. She returned to Mavis and told her about her findings. She even came clean about what really happened.

"Interesting theory, but why didn't you tell me the truth before?" Mavis said.

"Well... I..." Lucy wasn't sure how to answer that.

"You were afraid the one you love would have been your enemy." Mavis said as she read Lucy like a book. "I understand Lucy. What matters is that you managed to get this book."

"But Natsu won't come back to school now since that book is so important to Zeref." Lucy said.

"Not a problem. I just needed what was inside." Mavis said as she held up a tablet with a digital copy of the grimoire on it.

...

Dragneel Mansion

"So, I saw what was inside and found it fascinating. I just took it and walked away." Lucy said as she was returning the book to Zeref so Natsu could come back to school. Now that Mavis had a copy of the book with her on a tablet, she could return the book. "I didn't know it was yours at the time, but Natsu shouldn't be punished for something I did."

"I see..." Zeref said as he took the book. "Well, you did the right thing by admitting your mistake and returning it."

"So, you'll let Natsu come back to school?" Lucy asked.

"Seeing as how you "borrowed" it rather than him loosing it, I will." Zeref said. Lucy was glad to hear that. Invel showed her out, but there was still something she had to know.

"If I may ask, where did you get that book?" Lucy asked.

"It was actually a gift from my father. I've never seen another one like it. It's actually used for inspiration." Zeref said.

"I can see why. Bye." Lucy said as she was free to leave now. At least now this whole mess has been cleared. Now that Zeref got the book back, he placed it back in the safe and spoke to Natsu.

"I'm sorry I got mad over this, Natsu." Zeref said. "This book just means a lot to me. It was given to me by father before he and mother..."

"I get it. I probably would have been the same." Natsu said.

"They're gone, but I still have you." Zeref said. "However, I know I can't keep you trapped in this house."

"Does that mean I can go back to school?!" Natsu said with delight. Zeref confirmed he could and Natsu was so happy that he hugged his brother. Natsu got all his stuff and went straight there with all of his friends happy to see him again. As for Zeref, it turned out he had a digital copy of the book himself.

"I don't understand. If you had a copy on your computer, why did go through all this?" Invel asked.

"If Celestria and Salamondra had that book, they could have traced it back to me." Zeref said. "I had to keep my secret for now." Zeref played everything perfectly. As he reached for a hidden switch in the frame of the portrait, he went down a small elevator.

...

Zeref

Zeref went in a different part of the mansion that he was being used as his hideout. He pulled out his miraculous and placed it back on his shirt collar with it appearing as a simple black jewel in camouflaged mode and Anka emerging.

"Miss me, Anka?" Zeref said.

"At your service, Master." Anka reluctantly claimed.

"Darkness, Spread!" Anka was pulled into the miraculous and Zeref became Black Wizard. "Those fools don't suspect a thing. Celestria and Salamondra, I will find a villain that will defeat you and your miraculous will be mine. My greatest wish will be granted. I just need to wait for my next victim." The battle against Black Wizard has only begun.
