As the only guardian left in the world, Mavis made it her main responsibility to protect the miraculous. She kept moving from one place to the next and it became difficult to make friends. However, she did find one friend to turn to when she needed it.

"Mavis, there's no reason to run. With the power of the miraculous, we can do so much good in the world. You don't have to keep running."

"I can't ask you to take such a risk, Zera." Mavis said. "The miraculous must be used carefully and responsibly. I made a mistake with them once before. I can't afford to make another, and I can't drag my friend into it. that's why I must keep moving until the time does come for when they are needed. I must not allow anything to happen to them." Zera had hope of using the miraculous, but she trusted Mavis since she knows more.

"I understand." Zera said. "We're still friends forever, right?" She asked as she held out her pinky.

"Right. Friends forever." Mavis said as she intertwined her pinky to Mavis'. "You still have our charm, right?"

"Right here." Zera said as she took out a charm shaped like a butterfly. Being the guardian is a huge responsibility and some sacrifices had to be made, but these two friends always stayed friends and had hope to see each other again.

...

Present Day

"Okay, ladies! We have a big situation." Lucy said. She called her friends early for something she considered a crisis. "I heard that Natsu is heading for a trip with his brother and Yukino and her family is being tagged along!"

"That's it?" Levy questioned as she and the girls didn't see that as much of a problem.

"Of course!" Lucy said as she was fighting for her love. "Natsu is going to be on a trip with Yukino! Yukino is really nice, but she and Natsu have hit it off pretty well! What if they hit it off, become a couple, get married, and forgets all about me! I need ideas to help me!"

"Calm down, Lucy." Lisanna said.

"Yeah. It's not like it will be the end of the world. You don't even know what's going to happen." Cana said. "Knowing his brother, this trip will be strictly business."

"If you want, we could kidnap Yukino." Juvia said.

"Juvia!" Erza said as they were all shocked that she would even suggest a thing.

"Lucy, you said so yourself that Yukino is really nice." Levy said. "Natsu being with someone like her wouldn't be too bad, but if you are really so worried about that, you should just go and tell Natsu you like him."

"Levy, you know I can't do that." Lucy said as she just knows how it's going to happen. "Half the time, I can't say the words I want to say around him."

"I have an idea." Lisanna said. "You always get your words jumbled. What if you write it all down on a letter. That way, you can get your words in order, say what you want to say, and all you would have to do is give it to him."

"That's a great idea!" Erza said as all of them were in agreement with it.

"I don't know..." Lucy said as she wasn't sure, but she didn't have time to think about it. She looked to her window and saw Pixi was there and saw that she needed to talk to her. "On second thought, you're right! I'll do it! I can't waste any time since the train is going to leave soon! Bye!" She said as she got out of there as fast as she could, her friends thinking that was weird. Lucy hurried on down until she and Stella made it outside.

"I'm sorry to come all this way to bother you, Lucy." Pixi said.

"Is everything okay?" Lucy asked.

"Is there a problem with Master Mavis?" Stella said.

"Sort of. Please come when you can." Pixi said and just flew off. Lucy was wondering what it was about, but it didn't sound like an emergency.

"Should we go?" Stella questioned.

"It doesn't sound like an emergency, but it does sound like there's a problem." Lucy said. "We'll take the subway, save the energy for a transformation. Taking the train will also give me time to think of that letter to right." The more Lucy thought about it, the more she thought Lisanna is right. A letter might be just what she needs to finally confess her feelings towards Natsu.

...

The Subway

Lucy hit a train thinking it would be faster to reach Master Mavis than transforming. While she was on the train, it gave her the time she needed to put this letter together. She wanted to make sure it was perfect.

"I got it." Lucy said as she thought she had it. "Dearest friend, I want to take the time to tell you so much, but there never was. It's time for things to end. I don't want to go on like this anymore..."

"Don't you think you're overdoing it?" Stella said. "It sounds pretty, but you just need to come out and say that you like him."

"I want this to be perfect." Lucy said. She want this love confession to come out just the way she likes it, but words have a powerful effect, even if they aren't the results you wanted.

...

Mavis' Place

Lucy arrived to see what Mavis wanted her for. When she got there, she was surprised to see there was a doctor there and that he was wrapping her ankle in bandages.

"Oh my gosh! Mavis, are you okay?!" Lucy said.

"I'm fine." Mavis said. "I just tripped and sprang my ankle. The doctor said I'm going to be all good."

"I believe so, but you'll have to be off that leg for a while." The doctor said. Not exactly something Mavis wanted to hear today. "You might also be in some uncomfortable pain for a while. I've got a prescription for some painkillers."

"I can take that. You can I'm her little helper." Lucy offered. The doctor went along with it as he handed her the prescription.

"I'll get her some crutches to help her with this." The doctor said. "Just make sure she isn't on that leg so much." The doctor left it at that as he made his way out to get the crutches.

"I asked for you to come because I figured I was going to need help with this sprang." Mavis said as she had Pixi grab a piece of paper and a pen. Once she got that, she started writing. "Looks like I was right. I was hoping I could move around today, but that might not be the case."

"What are you writing?" Lucy asked.

"I was suppose to mean with a friend of mine today. I haven't seen her in a long time." Mavis said. "Could you give this letter to her, explaining the situation? Her name is Zera. You'll know it's her by seeing a butterfly charm and having twin tails in her hair."

"No problem." Lucy said as she thought she could handle all of it. Once Mavis told Lucy all that she needed to know, she made her way out.

"Lucy, how are you planning to do all of it?" Stella said. "Natsu is suppose to leave by train soon. How are you going to deliver your letter, Mavis' letter, and the prescription?"

"You're right." Lucy said as she realized that was a problem. "I can deliver Mavis' letter, and maybe get the prescription, but I'll never reach Natsu in time." She thought that was a problem until she realized a fast solution. "Unless I was someone else."

"Wait, Lucy!" Stella said as she knew what she was thinking. "You can't just transform into Celestria like that."

"Stella, Twinkle!" Lucy ignored Stella and just went ahead and transformed. Swinging around the city and leaping over buildings has her thinking she can do this. The problem is that she's in a bit of a rush.

...

The Train Station

For the first time in a while, Zeref was out of his house and leaving Paris. His brother went with him and had Yukino's family going as well. Just as the train was getting ready to go, Celestria made it just in time. When she transformed back, she hurried over.

"Natsu!" Lucy called and managed to get his attention before he got on.

"Lucy?" Natsu said as he stepped out.

"I'll make this quick." Lucy said as she was in a hurry. "I want you to have this. What I want more than anything is in this letter and you're the only one who can give it, Natsu." She said as she handed him a letter sounding like it was important. Natsu took it, but didn't understand it. "Just read it when you get the chance." Lucy didn't give any explanation. She just took off and had Natsu thinking. "I did it! I really did it!"

"Good for you, but you better hurry. You don't want to keep this Zera or Mavis waiting." Stella said. Lucy certainly agreed with that. When she got the chance, she transformed again and took off. Once Natsu got the letter, he boarded the train and sat behind his brother, who was having a hard time settling on the train.

"Everything okay, Zeref?" Vanessa asked.

"I'm just a little on edge. I just don't like being away from home." Zeref claimed.

"There's really nothing to worry about. If you're not willing to face what the world throws at you, you're doomed to fail." Vanessa said.

"I'm more willing than you might think." Zeref said considering what he really does. As for Natsu, he decided to read the letter now. He was rather surprised by what was on it.

...

The River

Millianna was down by the river and was playing around a few cats. While she was playing, a young woman with brunette hair in two tails came out. She wore and orange top without shoulders, dark pants, and boots.

"Hello, Millianna."

"Zera! This is a surprise!" Millianna said as they've met a few times before. "Are you here hoping to meet that friend of yours?"

"I am." Zera said as she took a seat next to her and pulled out her butterfly charm. "She's a lot like a sister to me and I miss her a lot. As you know, I can't explain why we don't see each other, but I have a feeling today will be different." While the two of them were talking, Celestria arrived. She saw Zera holding the charm, saw Zera's hair, and knew it had to be her.

"That must be Zera." Celestria said. She reached inside her whip and pulled out another piece of paper. Once she got it, she walked right over. "Hello."

"Celestria?! What are you doing here?!" Millianna said.

"I have something for this lady." Celestria said as she turned to Zera.

"I know very well who you are. Lovely earrings." Zera said with Celestria a little surprised. "I take it that's for me." Celestria was a bit surprised by what Zera might know, but she still gave her the letter. "Thank you, but you better get going. It's safer for you if we don't talk so much." Celestria was a little amazed, but she just moved on from it. She can see that Mavis has one close friend.

...

The Pharmacy

That just left one stop for her. Since she delivered everything else she had to, she just needed to get the painkillers for Mavis.

"Hello there." Celestria said as she walked in and pulled out the last piece of paper. "Here you go." She handed the paper to the pharmacist with the pharmacist reading it over.

"I'm sorry, but my name is Michaela, not Zera." The pharmacist said.

"What?" Celestria said. She took the paper and saw it was Mavis' letter to Zera. She saw she messed up big time. "If this is the letter for Zera, where's the prescription? Where's my letter?!"

...

The River

"Dearest friend, I want to take the time to tell you so much, but there never was." Zera read as she had Lucy's letter for Natsu by mistake. "It's time for things to end. I don't want to go on like this anymore..." Zera continued to read some of it, but she wasn't liking it. "What is all of this? Is Mavis saying she doesn't want to be friends anymore?"

"Zera, are you okay?" Millianna asked.

"I can't believe this!" Zera said as she didn't finish reading the letter. "We've been friends for so many years. Is it all because of her responsibilities? I can't believe she would do that!" Zera was so angry as years of hoping to see her friend again have all been for nothing.

...

The Train

With the aid of his miraculous, Zeref was still able to sense the misery Zera was feeling. He couldn't let an opportunity like this slip. He got up from his seat and made his way to the back.

"Attention, passengers. We're about to take off, so..." "We're not leaving!" Zeref said as he stopped him from doing anything.

"Who do you think you are?" The train employoee said.

"I am Zeref Dragneel! I am not feeling so well, and we will not leave until I am!" He claimed as he was getting in the man's face and was doing an excellent job of scaring him. That's why he reached for the speaker switch.

"Do to unforeseen consequences, our departure has been delayed." The train employee announced and the train was put to a stop. Zeref locked himself in the bathroom so he can transform.

"It would seem we have a great opportunity, Anka." Zeref said as he let him out. "I can feel the disappointment from years of waiting being for nothing. Anka, Darkness Spread!" He had Anka pulled into his miraculous and changed him into Black Wizard. When he transformed, he took out his sword and an etherious climbed out so he could fill it with dark power. "Flyaway, my evil etherious. Let's help her get another chance!" Even through the train, the etherious was able to get out and was drawn to Zera's misery.

...

Zera

Zera just tossed the paper away and just wanted to leave. Millianna grabbed the paper and read it. When she did, she noticed some important details that Zera appeared to have missed.

"Zera! Wait!" Millianna called, but it was too late. The etherious got to her and went inside her butterfly charm with her being connected to Black Wizard.

"Rewind, I'm Black Wizard. You want to get back the time you lost? I can help with that. In exchange, you must bring me the miraculous of Celestria and Salamondra."

"This time, rewinding time will heal these wounds." Zera said as she accepted the offer and transformed.

"Zera?" Millianna said as she didn't like what she saw. Zera was now in thin black armor. Her hair turned silver with two metal braces holding her hairs in place. Her skin turned white like snow, and she carried twin black swords modeled after the hands of a clock. As for the charm, it turned purple and black with it placed right on her chest with being surrounded by a symbol that looks like a clock.

"Time to get back the time that was lost." Rewind claimed. All she did was tap one of her swords on Millianna. When that happened, Millianna started talking backwards and did everything in reverse. A small red light also appeared on her sword. "As soon as both these blades turn red, I shall reverse time and get back all the time wasted on waiting for her." She got to work at once as she tapped other people and objects. With her powers, everyone was going in reverse and her two blades turned more and more red. She'll soon have all the power she needs to reverse everything.

...

Natsu

While Natsu was waiting for the train to start moving, he listened to his tablet and tried to amuse himself. He soon got an alert on it and saw it was about another villain attacking everyone. He sure hopes he can catch the train before it leaves.

"I better check on my brother!" Natsu said as he ran out of his seat and hurried to the bathroom. He tried one to get it opened, the one his brother was in.

"Occupied!" Black Wizard called.

"Sorry!" Natsu said and just dived into another one.

"We're not taking time off, are we?" Igneel questioned.

"We hardly do." Natsu said. "Igneel, Fire Up!" Igneel was pulled into the ring and he became Salamondra. Once he did, he snuck his way off the train and hurried after that villain.

...

Celestria

Once she realized the mistake she made, Celestria moved around the city as best as she could. She had to fix things with Zera, but she was having a little trouble finding her. She continued to search around until she heard people screaming. Celestria followed the screams to the park and soon spotted Rewind.

"Go ahead and run. I have all the time in the world." Rewind claimed. Celestria got a good look at her and spotted the charm on her chest.

"Oh no! If I gave her my letter by accident, it's probably a good thing Natsu didn't read it." Celestria said. Now that she knows her mistake, she has to fix this. Rewind continued to make people go in reverse, but she soon had Celestria's whip around her. Celestria pulled with all her might and threw her just outside the park and near a plaza.

"You!" Rewind said.

"Listen to me! There was a big mistake!" Celestria said as she tried to explain the situation.

"I'll say." Rewind claimed as she was greatly upset. She jumped straight at Celestria, but she moved out of the way in time. Once she did, Celestria grabbed Rewind by the arm and tossed her aside.

"I can help you fix this, but you must give up your etherious!" Celestria demanded.

"Not a chance!" Rewind said. She knew she had to get Celestria off her back, and she saw how when she saw a woman pushing her baby as she tried to run for it. Rewind jumped straight at her and tapped one of her blades against her. When that happened, she started moving backwards, and a car under the same power was heading straight for her.

"Oh no!" Celestria said as she had to act now. Letting Rewind go for now, Celestria swung over to the lady and her baby. She was able to save them both before the car hit them and placed them somewhere safe. "There you go, ma'am." She said, but the lady was still under the villain's power and just kept going backwards. Celestria could see this was going to be a real problem. That was right when Salamondra appeared and acted like he was going backwards.

"Okay you are, star little my?" Salamondra joked, but all that got him was a glare. "What? Everyone else is going backwards."

"Because they were hit by a supervillain. We need to get her." Celestria said.

"I do got somewhere to be, so we need to make this fast." Salamondra said. Without a moment to lose, the two of them got moving. As for Rewind, she continued to make everything go backwards. Each time she did, she gathered more and more power with her weapons turning more and more red.

"This is all good, but I need much more power." Rewind said as she saw she wasn't making much progress.

"That's far enough!" Celestria called as they caught up to her.

"Instead of going back, I think it's time someone hit pause on you." Salamondra claimed.

"Perhaps you two will do." Rewind said. "If I hit the both of you, I'll have all the power I need."

"Yes, but be sure to follow them to reveal their identities." Black Wizard told her.

"I can do you one better, Black Wizard. I can follow them to the one I'm looking for, the one who gave them those earrings and ring." Rewind said with Celestria hearing that, learning it's big trouble for them.

"You know the guardian?!" Black Wizard questioned as he couldn't believe it.

"Mavis? Of course." Rewind claimed. "She's been in hiding for a long time to protect the miraculous, but it looks like we both have a chance to get what we want."

"What a delicious stroke of fate." Black Wizard said as things appear to be very fortunate for him.

"Oh no! Salamondra, I saw Master Mavis earlier! If she touches me, I'll be leading Black Wizard to her!" Celestria said.

"No worries. I'll keep you covered." Salamondra said as he stepped in to protect her. Rewind wen right at the two of them as she jumped at both of them, but Salamondra blocked both and kicked her back. Celestria tied her whip around a trash can and tossed it right at her, but Rewind touched her blades to it and sent it back, but they both jumped out of the way. Salamondra charged right at her and tried attacking, but she blocked each one of his attacks. Celestria jumped over them and tried getting Rewind from behind, but she was able to kick her back. Rewind reached out and tried to use her powers on Celestria, but Salamondra grabbed her arm and tossed her back. Rewind balanced herself as she tried again on both of them, but they both dived to the side. Before she turned back around, Salamondra extended his staff into her back and knocked her into a plaza. When that happened, Celestria tied her whip around it and pulled with all her might as the plaza collapsed on top of her. However, with Rewind's power, she restored it easily.

"Is that all you got?" Rewind said as she got back up, but saw they were gone. "You can't hide forever!" She went straight into the park and tried searching for them. The two of them took cover behind the fountain and kept a low profile.

"Any idea where the etherious is?" Salamondra questioned.

"I can't explain, but I know it's in the charm on her chest." Celestria said.

"But how are we going to get it without getting touched?" Salamondra said.

"With this. Open the Celestial Gate!" She used her powers and got herself a Taurus baseball.

"Talk about having a ball." Salamondra said. Celestria looked to see how she can use the ball. She spotted the fountain and some trees. Celestria believes she might have something. She looked around for Rewind and didn't see her.

"Now's our chance." Celestria claimed as the two of them got moving. She started by drawing an X in the ground. "Can you do trick shots?"

"What are you looking for?" Salamondra asked.

"Off the fountain, long as you can against the trees, and back here." Celestrai said. "Throw the ball as hard as you can. Time will be on our side." She passed the ball to him and activated a timer in her whip. Salamondra gave the ball a good toss. The ball bounced against the fountain and made its way around the trees. It went around for a while until it came back to her.

"There you two are!" Rewind said as she found them.

"Just in time. Catch!" Celestria called as she threw it right at her, but she held out one of the blades and the ball was placed under her power. "Perfect." She whispered as she had the save time go in reverse. "Make sure she's near the X."

"Mavis made a foolish mistake choosing you if all you can do is throw a ball." Rewind said as she went right at the two of them. She kept trying to put the two of them under her power while they tried to keep her on that spot. As for the ball, it kept retracing the path it took earlier. Celestria kept an eye on the timer and saw it was about to hit zero.

"Now!" Celestria called.

"What?" Rewind questioned until she noticed the ball as it bounced off the fountain and smashed right into the charm with the etherious flying out. "No more evildoing for you, little etherious. Time to de-evillize!" She activated her whip and was able to catch it to purify it. "Gotcha! Bye-Bye, little guy." She said once she released it. "Miraculous Starlight!" She tossed the ball into the air and it turned into the magic stars that restored everything to the proper time flow with Zera being restored.

"Pound it!" The two heroes bumped fists.

"But I still don't know what this was about." Salamondra said.

"We girls have our secrets." Celestria said. Salamondra didn't get it, but there was no time as he just took off and was on his way back to the train. Celestria then used her whip and got the real letter out. "I'm sorry, Zera. This is the letter that was meant for you." She handed her the paper. Zera read over it and was happy again.

...

The Train

"You may have won this time, Celestria, but now I know more." Black Wizard said. "This Mavis might be hiding, but she will be found." Since the fight was over, Salamondra made it back to the train. When they both transformed back, both of them stepped out at the same time.

"You seem better." Natsu said.

"Yes. I guess I just needed a little pick-me-up." Zeref claimed with them getting back to the trip, but he now knows the name of the guardian. Black Wizard is one step closer to his goal.

...

Days Later

After some time has passed, Mavis and Zera could finally meet with each other. It was a little awkward since the two of them haven't seen each other in a long time, but they are just glad that they got to see each other again.

"Zera, I'm sorry it took so long for us to see each other again." Mavis said.

"Don't be. I understand that protecting the miraculous is a big responsibility." Zera said. "I understand even more now. Black Wizard knows that I know you. It looks like I'll have to go into hiding until he's beaten."

"I'm sure the ones I chose will succeed." Mavis said with Zera having faith in her. "Still friends?"

"Forever." Zera said as they locked that promise with them intertwining their pinkies just like all they did those years ago.

...

The School

Another day of school came, but the girls wanted to know. They just had to know if Lucy really went through with it and gave Natsu the letter that confessed her love.

"Well?" Erza said.

"Did you give him the letter?" Levy asked as they all wanted to know.

"I gave him A letter." Lucy said, but none of them understood. "I screwed up. I had a few other letters with me and I think I might have given him the wrong one." All of them couldn't believe she would be that careless. Her big chance and she blew it...again.

"Hey, Lucy." Lucy got freaked from that voice. They all cleared the way and spotted Natsu with something in his hands. "I got that thing you wanted." He said as he handed it to her. "You made it sound pretty important, but I got the best ones I could." He handed her a small white bag.

"Uh... Thank you..." Lucy said.

"No problem." Natsu said as he went in the school with Lucy so still.

"Did you hear that?!" Erza said. "He was thinking about you while he was on his trip, and he helped you out with something important!"

"What did he give you anyway?" Cana questioned as she grabbed it and they all took a look at it.

"Painkillers?" Levy questioned as none of them got it. Lucy wishes she could redo this moment, but she can't. All she can do is wait for another chance to be together with him like how Mavis and Zera are waiting. They can't go back, only forward, but tha't just how life is.
