It's been some time since Lucy and Natsu were given their miraculous. Not only have they been given powers, they're feeling love. Too bad they can't know for the time being. Now that Lucy is feeling love for Natsu, she's excited for today. She came down from her room with a present in her hand.

"Lucy, don't forget that I want you to clean your room after school." Layla said.

"Mom, I can't. It's Friday and I'm hanging with Levy and Erza." Lucy said.

"Fine, but don't blame me if I clean it only to find something private in there." Layla said. A clever parent trick to get your child to do what you ask them to.

"Fine. I'll do it." Lucy said. "Just let me able to deliver my present. It's someone's birthday today." Lucy was excited for this because of whose birthday it is.

...

Natsu

It was Natsu's birthday today and he was hoping it was going to be different today. As he was finishing eating alone, Invel came over with a tablet.

"Your schedule, Natsu." Invel said as he handed it to him.

"Thanks." Natsu said, but was hoping for good news. "Have you talked to Zeref about my party?"

"Well... Your brother doesn't think it would be a good idea." Invel said. Natsu was rather disappointed in that. He hoped his birthday would be different this time.

...

The Highschool

"Dude, that is seriously not right." Gray said. When Natsu arrived at the school, Natsu told him how his brother won't allow him to celebrate his birthday with a party.

"I should have known. He's crazy protective of me, but sometimes I think he's only thinking of what's in his best interest, not mine." Natsu said. "What with him being an adult and me still in school, he says he has to act responsible for my own good."

"How is having a party a bad thing?" Gray questioned as he felt bad for him. "How about you let me talk to him? I bet I can change his mind."

"I don't know, Gray. Zeref doesn't change his mind so easily." Natsu said.

"Trust me. You need to have some fun in your life." Gray said. While they were talking it over, Lucy and her friends ducked and covered as Lucy was trying to get the nerve to give him his present. She told Levy and Erza about her crush because she figured she was going to need help.

"Go on, Lucy. Give him his present." Erza said.

"What if he doesn't like it?" Lucy asked as she was too nervous.

"You can do it." Levy said as they were encouraging her to go. Meanwhile, Taylor just heard about Natsu's birthday.

"It's Natsu's birthday and you did nothing!" Taylor complained to Samantha.

"You didn't tell me to order anything." Samantha said.

"Seriously? What good are you?" Taylor said. "Find something that Natsu will love." Samantha got to work as fast as she could. She spotted Lucy standing with a present as well as Erza and Levy giving her a push in Natsu's direction. Lucy tried to be brave enough for Natsu as she walked up to him and Gray and them noticing.

"Hi, Lucy." Natsu said.

"Hi. Hoppy...I mean Happy Burt...No. I'm trying to say..." Lucy was trying to give Natsu his present, but Taylor pushed her out of the way.

"Happy Birthday, Natsu Dear!" Taylor said as she hugged him and tried kissing him. "Did you get my present?"

"Actually, no." Natsu said.

"What?!" Taylor said as she acted shocked. "Those utterly useless workers. Don't worry. It's going to be something you love." She said as she latched on his arm and pulled him into school with him. Lucy was annoyed with her friends helping her.

"That girl knows what she wants and go gets it." Erza said. "Too bad she makes it look bad."

"Unlike me." Lucy said as she felt ashamed that she couldn't give Natsu her present.

"Don't worry. You don't need to give it to him directly." Levy said as she had something else in mind.

...

Dragneel Manor

"Are you crazy?" Lucy said. They stood right outside the gate of Natsu's house for they headed there after school. They decided to leave the gift for Natsu in his house. "I can't do this."

"You're not really talking to Natsu. Just say you wish to give Natsu his gift." Levy said.

"It shouldn't be a problem. Just ring the bell and tell them why we're here. They'll surely let us give Natsu his present." Erza said. Lucy didn't see much harm, and she certainly wants to give Natsu his present. Still, just thinking about it made her nervous. Erza could see Lucy wasn't going to do it, so she rung the bell for her with Levy and Erza ducking out of the way. A camera came out of the wall and pointed right at Lucy.

"What is it?" Invel said on the other line.

"Hi. I'm in Natsu's class and I have a birthday gift for him." Lucy said with her heart beating like a drum.

"Just put it in the box." Invel said as the mailbox opened up for her. Lucy put it in and it automatically closed.

"Thank you." Lucy said as the camera pulled back into the wall. Lucy was getting all giddy that she actually pulled it off. "It actually worked! I did it!"

"Did you sign the card?" Levy asked. When Lucy realized that, her joy quickly turned to feeling stupid. Meanwhile, Invel was able to get the gift as he brought it to his desk.

"Who was that, Invel?" Zeref asked over video.

"A friend of Natsu's giving him a birthday present." Invel said.

"Did you remember to get my gift for him?" Zeref asked.

"Uh... Of course, sir." Invel said, but he actually didn't.

"Good." Zeref said and ended the talk. Invel felt like he was going to be in big trouble if he doesn't find a gift from Zeref. That was until he saw there was no signature on the present. He can just claim it was from Zeref. When Invel thought he was in the clear, he heard the doorbell. He activated the security camera and saw it was Gray.

"Hi. Is it okay if I come in and talk to Zeref Dragneel? It's about Natsu." Gray said. Invel let Gray in and the two of them waited for Zeref to show himself.

"What is the meaning of this?" Zeref said as he showed himself at the top of some stairs. "You wanted to talk to me about my brother?"

"Yeah. I mean...Yes, sir." Gray said as he was trying to act formal. "It's Natsu's birthday and he really wants to have a party with all his friends. I really don't see why you won't let him." So far, it wasn't going well as Zeref glared down at him. "Natsu told me a lot about the two of you. He's a pretty good guy. Doesn't he deserve a party?" Right when he asked that was right when Natsu got home.

"Gray? What are you doing here?" Natsu asked.

"Trying to convince your brother to let you have a party." Gray said.

"Listen here." Zeref said. "I decide what's best for my brother. Without our parents, he's now my responsibility. In fact, I just decided that you're a bad influence on him and I'm not sure I want you around him."

"Bro, you can't do that!" Natsu said. "He was just trying to do something nice for me." Zeref didn't seem to care as he turned away and walked up the stairs. Gray couldn't believe how cold the guy was being.

"It's time for you to go." Invel said. He ushered Gray out the door with Natsu following.

"Gray, I'm sorry." Natsu said.

"Your bro has some serious issues." Gray said as he walked out of there with some anger building up.

...

Gray

Gray went over to the park to gather his thoughts. He grabbed a hold of his sword necklace and couldn't believe Natsu's own brother acted cold. He looked around and saw other adults telling their kids what to do while the kids just wanted to play.

"We do what they say. All we ask is for some fun, but there are some who act cold." Gray said. His grip on his necklace tightened his grip with anger.

...

Black Wizard

"Not fond of getting the cold shoulder." Black Wizard said as he was getting ready to use his power. "Feeling powerless to do anything against adults when they say no. Well, I can change that." An etherious flew into his hand and he placed evil energy into it. "Flyaway, little etherious, and evillize him!" He released the etherious out on Paris as he found his new target.

...

Gray

The etherious flew all the way to Gray. It entered his necklace and Gray could see and hear Black Wizard before him.

"Subzero, I'm Black Wizard. Adults can be so cold. Well, you'll be even colder. In return, you must bring me the miraculous of Celestria and Salamondra."

"They'll be frozen solid when I'm done with them." Gray said as he was transforming. His hair was standing on ends with black markings appeared on his right arm and face. He wore dark clothing with no shirt under his jacket. "Time to see how the adults like getting the cold treatment." He placed his fist over his hand and conjured a storm of ice and snow.

...

Lucy

"I'm finished." Lucy said as she climbed down from her room after she finished cleaning it like her mother wanted.

"Thank you, sweetie." Layla said. "You know, I've been thinking. Since it's a birthday of a friend, maybe..." She didn't get to finish that as a powerful wind blew the windows open and it became freezing.

"What's with that wind?" Lucy said. When it settled down, she was shocked to see her mother was frozen. "Mom!" Seeing a frightful sight, she hurried down the stairs as fast as she could. "Dad, Mom is..." She didn't finished as she saw her father was frozen as well. It was just them. She looked outside and saw others were frozen.

"Looks like Black Wizard has etheriouized someone again." Stella said.

"I better find his latest villain fast." Lucy said. "Stella, Twinkle!" Stella was pulled into her miraculous and she transformed into Celestria. Once she transformed, she made it outside and got a better look to see crying children with frozen adults. "That's weird. It's only the adults." Celestria said as she wondered what was going on.

"No more adults." Subzero appeared on the ice. "We're free to do whatever we like. You can finally have some fun."

"Gray?! Oh no!" Celestria said as she recognized him. She knew she had to find him and save him fast.

...

Natsu

As for Natsu, he was home and was all alone. It wasn't feeling much like a birthday for him.

"Wow. How memorable." Natsu said as he left the dining room. He grabbed his bag and was on his way out, but he noticed that there was no one else around. "Zeref? Invel? Jacob? Where is everyone?" Natsu thought this was rather weird. He stepped outside, but was surprised to see his class outside and was cheering for him. "What's this?"

"What you wanted?" Natsu looked to the side and spotted Subzero leaning against his house. "You're finally getting the birthday you wanted."

"Gray?!" Natsu said.

"There's no one around to stop us now. We're free to do what we like." Subzero said. He had everyone cheered and ready for a party. Natsu ducked back inside and was ready to transform as he let Igneel out.

"Hang on. Before you transform, this could be your chance to have the party you always wanted." Igneel said.

"But Gray's been etheriouized. I've got to do something to help him." Natsu said.

"He's not going anywhere. You can finally celebrate your birthday the way you deserve." Igneel said. It actually was tempting for Natsu.

"You're right. He's not going anywhere." Natsu said as he was finally going to celebrate his birthday the way he wanted to.

...

Celestria

Celestria searched around for where Subzero might be. She looked until she heard music and saw lights shining by Natsu's house.

"Looks like I'm crashing a party." Celestria said as she moved fast. Meanwhile, Subzero was being the DJ for the party. Natsu was having a fun time as he was actually enjoying the party.

"Great party, huh?" Natsu asked a fellow student, but the student didn't seem as happy. In fact, Natsu had a look around and saw no one was really having as much fun as he was. Didn't really look much like a party.

"Excuse me." Samantha said as she was trying to get Subzero's attention.

"What do you want?" Subzero asked.

"Taylor would like to put a request." Samantha said.

"I don't take requests." Subzero said. Samantha was about to ask for more, but Taylor pushed her out of the way.

"Please. It's Natsu's first slow dance." Taylor pleaded with him as she batted her eyes. Subzero smirked as he liked the sound of that. He changed the music and slowed it down. Everyone paired up with them dancing with each other. Taylor took her chance as she walked over to Natsu. "Care to dance?" She grabbed a hold of him and started dancing. She's really the only other person enjoying this because she gets to be with Natsu. As for Celestria, she showed up and saw the party going on. She also saw Taylor trying to kiss Natsu with him trying to pull away.

"I don't think so." Celestria as she used her powers improperly. "Open the Celestial Gate!" She summoned for a random item and it appeared to be to be a frisbee with the Sagittarius emblem on it. She looked around and saw a ledge and the music control she could use. She tossed the frisbee and it bounced off the ledge and hit the music controls with the song changing to one with a faster beat.

"Hey! Who messed with my music!" Subzero said.

"That should take care of that." Celestria said. She was about to face Subzero, but she heard her earrings beeping and was about to change back. She moved fast as she landed on the streets. "Lights Out." Once she said the command, she changed back to normal with Stella flying out and in her hands.

"Lucy!" Stella said with disapproval.

"I'm sorry, but it was an emergency." Lucy said.

"You mean jealousy. You shouldn't use your powers for personal reasons." Stella said.

"I know, but Subzero isn't going anywhere. We just need to find you something to eat." Lucy said. She hid Stella in her bag and moved inside the party. She headed for the snack table and passed some cookies to Stella.

"Lucy!" Lucy looked and saw Levy and Erza spotted and hugged her.

"We were afraid something terrible happened to you." Erza said.

"Come on. We've got something to show you." Levy said as they took Lucy with them and into Natsu's house.

"Look." Erza said as they found Lucy's present on the desk. "Despite the circumstances, take the opportunity to sign it."

"Actually..." Lucy tried to think of an excuse, but the girls just pushed her in and covered for her.

"Lucy, we can't now." Stella said as she was still eating. Lucy knows that, but she saw it as her chance.

"It will only take a minute." Lucy said as she grabbed a pen and paper with her signing the name. Meanwhile, Jellal wasn't dancing with everyone else. Subzero spotted that and didn't like it.

"Why aren't you partying with anyone else?" Subzero said.

"Chill, man. I just don't want to dance." Jellal said. Wrong answer to give to Subzero. As Lucy was finishing signing her gift, she heard something outside. She took a look and saw Jellal was frozen with Subzero having a grin crazy people would have.

"Oh no! Subzero's loosing it. I shouldn't have waited." Lucy said.

"I'm charged and ready to go." Stella said. Lucy's put this off long enough. As for everyone else, they kept dancing with Subzero forcing them to.

"That's it. Dance or be frozen like the rest of the adults." Subzero said. Natsu realized what a big mistake this was as he saw no one was having fun. Subzero continued playing the music until he saw his equipment pulled apart. "Hey! Now who messed with my music!"

"That would be me!" Celestria said as she showed herself. "The party is over, Subzero." With her arrival, Natsu took the opportunity to sneak away so he can transform.

"I wasn't aware that Subzero was forcing everyone to party. I knew I should have done something." Natsu said.

"At least you had some fun." Igneel said.

"Time to get serious. Igneel, Fire Up!" Natsu said as he transformed into Salamondra and joined the real party. Subzero placed his fist in his hand and unleashed lances of ice at Celestria, but she jumped down and avoided them. He tried shooting shards of ice, but she used her whip like a shield and blocked each attack. She lunged herself at him, but Subzero met the attack as the two of them passed each other.

"Not bad, Celestria, but not good either." Subzero said.

"Hey! Who started the party without me!" Salamondra called as he made it look like he just showed up. He jumped down and twirled his staff at him, but Subzero caught it and tossed him over to Celestria.

"What's with all the party crashers?" Subzero said.

"Subzero, you need to stop this and free everyone from your ice." Celestria demanded.

"Why? No one can stop us from having fun. No adults to get in our way of fun." Subzero said.

"Kids need adults. They love them and keep them safe." Celestria said.

"Brothers are a different story." Salamondra mumbled.

"You're worried about them so badly? How about you join them." Subzero said. He unleashed more ice at them and trapped them in a block of ice. The two of them tried pounding away on the ice, but it wouldn't break.

"Excellent work, Subzero. Taking their miraculous should be easy now." Black Wizard said in Subzero's head as he could see victory.

"We better do something or the two of us will be trapped in this ice." Celestria said. Salamondra waved his eyebrows as he actually liked it, but Celestria smacked him in the head. "Just melt the ice already."

"Dragon Fire!" Salamondra used his power and touched the ice. It turned to steam and freed them with everyone cheering. The kids cheering for them irritated Subzero.

"You all need to chill!" Subzero said as he used his powers and froze everyone.

"Oh man! We need to end this fast! Where is the etherious?" Salamondra said.

"Take a look. His right hand has been closed the whole time." Celestria said. "It must be there. Time for this party to end. Open the Celestial Gate!" Celestria used her powers and the stars formed a vase with the Virgo sign on it. "A Virgo vase?"

"I've only got a few minutes left, but I'll try to buy you some time." Salamondra said as he went to fight Subzero. Celestria looked around as she tried to find how to use the vase. She spotted Subzero's arms, Salamondra, the vase itself, and a spotlight.

"That's it!" Celestria said as she figured it out. She jumped up to the lights and shined a light on Subzero. The light shined in his eyes and blinded him. "Salamondra, get this on his free arm!" She tossed it to him. He caught it and stuck it on Subzero's arm. Subzero tried using his power, but he felt the vase stuck on his arm and he couldn't do anything. "Now grab him!" Salamondra drabbed a hold of him and tried to hold him in place. Celestria moved fast and started to tickle Subzero's pit. He had to laugh and it weakened his grip on the item. He dropped the tiny sword from his necklace and Celestria stomped on it. She broke it with the etherious being free and flying out. "No more evildoing for you, little etherious." She said as she traced the end of her whip and began to twirl it around as it extended out. "Time to de-evillize!" She tossed the whip at the etherious and grabbed it with it being trapped in a ball of light. "Gotcha!" Once she caught it, she purified it and set it free. "Bye-bye, little guy." All that was left was to take the vase off and tossed it in the air. "Miraculous Starlight!" She called upon the streams of stars as they freed everyone from their icy prison. Gray changed back to Gray and had no idea on what happened.

"What am I doing here?" Gray questioned.

"Pound it." Celestria and Salamondra said as they bumped fists.

...

Black Wizard

"Enjoy your victory while you can, Celestria. Someday, someday soon, you're defeat will come." Black Wizard said. "Nothing shall stop me from reaching what I desire!"

...

Invel

After a fiasco of a party, everything returned to normal. Invel got back to work at his desk when Zeref contacted him.

"Invel, did Natsu enjoy his gift?" Zeref asked.

"Uh... I was just about to check." Invel said. He almost forgot. He spotted the gift from Lucy was still there. He removed the signature and hurried over to Natsu in the dining room and acted professional. "A gift from your brother." Natsu was surprised that his brother actually got him something.

"Really?" Natsu said as he couldn't believe it.

"Happy birthday, Natsu." Invel said as he let him get back to eating.

...

The Highschool

"It won't be here for three days?!" Taylor said as she just found out the news about her gift for Natsu.

"I'm sorry, but they say there's nothing they can do." Samantha said. Taylor groaned with annoyance as she stormed into the school with the girls and Gray seeing her off.

"Hey, guys." All of them saw Natsu arrived at school with a white scarf around his neck.

"He's wearing it! He's wearing my gift!" Lucy said with such joy.

"Killer scarf, Natsu." Levy said.

"Thanks. Can you believe Zeref got it for me?" Natsu said. Lucy was surprised to hear him think it was from his brother. "He never got me this before. It's better than any gift he gave me."

"I guess he's not so bad." Gray said.

"Gray, I'm sorry about what Zeref said the other day." Natsu said.

"We're good, man." Gray said as he got over what happened. "I get he's just trying to take care of you, but I'm sure he'll come around." Natsu felt lucky to have a friend like him. As the two of them walked in, Levy and Erza felt bad that Lucy made him the scarf herself and she didn't get any credit.

"Aren't you going to tell him you made that scarf?" Levy asked.

"He seems so happy thinking it was from his brother. I don't want to ruin that." Lucy said.

"You're amazing, Lucy, and he'll see that himself one day." Erza said. It might not have been the birthday Natsu had in mind, but it was a memorable one. Lucy still has hope she'll be with him and Natsu has hope things between him and Zeref will change for the better.

AN: I'm just going to save some time and say who is in their class. Other than the seven ones that have been made clear, here are the rest. Cana, Lisanna, Juvia, Jellal, Gajeel, Hibiki, and Loke.
