Zeref's latest plan might not have gone the way he wanted it to, but he did get something out of it. He now has the key needed to completely restore the unicorn miraculous and bring it back to full power and make himself stronger. What he did was take some of the ingredients such as pour meteorite dust into molten gold. With a few other ingredients mixed in, there was one thing left to do.

"Here we go." Zeref said as he held the miraculous by a pair of tongs and placed it inside the mix. "Heal yourself!" He commanded and that caused a bright light to go off. When he pulled it out, the miraculous was completely restored. "Yes! As good as new!" The miraculous was fully restored and him to use. He placed it over his wrist and called Uniss out with Anka.

"What's going on? I feel so great!" Uniss said and then noticed Anka. "Anka!" She called as she hugged her fellow kwami.

"I hate to ruin your joy, but I'm afraid we're in trouble." Anka said.

"Quite right." Zeref said. "With both of you, my power will increase to great power! Anka! Uniss! Unify!" Zeref fused the power of two miraculous at once. His outfit changed into black royal-designed clothing with pants, a top with white lining around it. He maintained his wing-shaped mask, but his hair looked wilder as parts of it stood up. He was also now holding both weapons that came with both miraculous.

"Now, I am Black Knight. With this new power, Celestria and Salamondra's miraculous will eventually be mine." With a new name and new abilities, there's no telling what he's capable of.

...

Lucy

Lucy's life has also gotten more complicated. Now that Mavis has revoked her position as Guardian, it has now fallen on Lucy to protect them. She had the box safe in her room at the moment, but it's form completely changed into a star. She examined it to wonder how it worked.

"Are all the kwamis really in there?" Lucy questioned.

"That's right. The box is actually much bigger for us kwamis on the inside." Stella said. "With the use of magic, they all in a large space where they are safe."

"How come the box looks different than it did before?" Lucy asked.

"The box takes on the form of whoever has been named Guardian." Stella said. Lucy tried figuring out how this new box worked. She started by pressing a button that was right in the center. That caused the top to open out and a series of smaller drawers to open up on the sides. It also released all the kwamis as they explored around Lucy's room and taking in all the incredible devices and such like her computer and her phone.

"Hey! All of you settle down! Someone could see you!" Lucy said as she tried to gain control of the situation. It got real bad when she saw Christi fly out her window. "Hey!" She called as she went after her.

"Oh my! Carriages without horses?!" Christi questioned as she marveled at the cars.

"Get in before someone sees you!" Lucy called as she grabbed Christina and got her back in. All the kwamis were causing all kinds of mischief with her stuff and gadgets. It also certainly didn't help that she saw Levy was requesting a chat on her computer. Without thinking, Lucy responded to it.

"Lucy? Are you okay?" Levy asked with Lucy seeing all her girl friends were there.

"Hey! Sorry! I'm guessing you're wondering about the new...plushies I have." Lucy said as she was trying to come up with an excuse for all the kwamis in her room.

"What plushies?" Erza questioned.

"Lucy, we don't show up on technology." Stella reminded with Lucy feeling stupid.

"You have new plushies? Can we see?" Lisanna asked.

"Uh... No!" Lucy said as she she's still trying to control the kwamis from causing so much trouble. "I'm... I'm in the middle of some exercise!"

"Exercise?" Cana questioned.

"Hold on. You're acting very weird. Is Natsu there?" Levy questioned as they all thought that was it.

"No. It's just that..." Lucy tried to figure out how she was explaining her strange behavior, but she didn't get the chance as she heard her phone and saw that Sting was trying to call her. "Sting? Sorry! I've got to go!" She said as she ended the chat and answered her phone. "Hey, Sting."

"Hey. Uh... Thanks for the photos." Sting said.

"What photos?" Lucy said.

"The ones you sent of your room with photos of Natsu." Sting said. Lucy took a quick look and saw the kwamis messed with her phone by sending random photos of her room.

"Uh... Sorry about that. I must have done something wrong with my phone." Lucy said. "Anyway, what did you call me for?"

"About our date. Did you forget? I'm right in your living room." Sting said.

"Lucy!" Jude called to tell her that Sting was here. Lucy completely forgot that she had a date with Sting. They've gotten real close lately, but her new role has caused some problems.

"Uh... I'll be right down." Lucy said as she ended the call and had to move fast. She put the box in her desk and told all the kwamis to get in there so they stay hidden. "I'll be back. Just stay quiet and be good." She told them before she hurried on down with her seeing Sting there with her parents. "Sorry about that."

"Everything okay?" Sting asked.

"Yeah. I'm sorry. I actually did forget about our date." Lucy said. "What did you have in mind?"

"I was thinking of catching that new movie? You interested?" Sting asked.

"I actually could use something simple and relaxing." Lucy said as she was already under some stress. The two of them got going with Lucy's parents glad to see her daughter is finally pursuing some romance.

...

The Movie Theater

"You have an interest in astrology?" Sting questioned.

"Yeah. I always loved looking at the stars, trying to find all the constellations." Lucy said as the two were getting to know each other. Sting and Lucy hit the theater just like Sting suggested. Lucy was actually having a good time and certainly enjoyed being around Sting. "Aren't you interested in the stars?"

"A little. The one constellation that interests me is the one name Ophiuchus." Sting said.

"The Snake Charmer?! I'm interested in that one, too! It's considered the thirteenth zodiac." Lucy said as she was enjoying her time with him more and more. The two of them went down to the theater and took their seats for the movie.

"Since we are at the movies, what is your favorite scene?" Sting asked.

"Favorite?" Lucy questioned as she tried to figure that out. "Nothing too specific, but I do like in those romance movies how two people can be together after all they went through."

"Same here." Sting said as he reached of and moved her hair a bit. The two of them looked right at each other and this seemed like the ideal moment as the two of them were about to kiss, but that was when the whole place began shaking.

"Uh... I think we're going to need more popcorn!" Lucy said as she knew she had to slip out because duty calls. Lucy hurried out of there and transformed into Celestria. Once she did, she went to the roof of one of Paris' highest buildings and could see Kitty Cat was back with her manipulating all the cats, gathering them to be used like wrecking balls. Needing her partner, she tried calling Salamondra.

"Hey, my little star. Calling to remind you about our little patrol. I'm at our rendevou, but no sign of you. Did you forget? I'm here waiting for you." Salamondra left a voicemail, but the real Salamondra snuck up behind her as she was distracted.

"Boo!" Salamondra called, but she got spooked and threw him off the roof instead.

"Salamondra?!" Realizing it was him, she used her whip to save him with him swinging against the window. "Stop fooling around, Salamondra. I could have seriously hurt you."

"You're telling me to be more responsible when you missed our annual patrol?" Salamondra questioned.

"Sorry. I've just been distracted lately." Celestria said as she tried getting him back up.

"I bet. Being Guardian must be a real honor." Salamondra said as he got back up there.

"Well, let's end this fast." Celestria said as the two of them got to work. Meanwhile, the movie was going on. Sting tried to enjoy it, but he kept wondering where Lucy was. It took a lot longer than she thought, but she was finally able to beat Kitty Cat and get back to the movie.

"Sorry about!" Lucy said as she rushed back to her date. "They needed to refill the machine, but it was on the fritz. Then, people were getting an alert about an attack and we were all escorted to some other place in the building." She said as an excuse, but noticed the situation she was in. "What?! I missed the whole movie?!"

"Yeah, but we can catch it another time." Sting said as he just let the whole thing go. Lucy felt lucky that Sting was thoughtful, forgiving, and considerate. She wanted to be with Natsu, but maybe things can work with Sting.

...

Days Later

Lucy and Sting continued to go out with each other, but her responsibilities as Celestria made it difficult. For example, the two of them got some ice cream, but she noticed the candy monster attacking. She had to pull away from there. After school, Sting tried walking with Lucy, but she noticed an etherious flying by and had to take care of it. Sting and his band even gave a performance at Gajeel's house boat, but he noticed Lucy still hasn't shown. She didn't arrive until it was a little late, but Sting was rather disappointed. Lucy kept disappearing and she wouldn't tell him the truth of what was going on. Sting wants Lucy to trust him enough to tell him and wants her to be able to tell him. Lucy did feel bad about lying to Sting all the time, but she doesn't really have a choice. Having enough patience, Sting decides to pull something that will get Lucy to tell him the truth. That's why he lured her to a spot under a bridge.

"What are we doing here?" Lucy asked.

"It's a bit of a secret spot of mine. Just listen." Sting said. "If you listen closely, you can hear something like a melody down here." Lucy listened carefully and heard a melody that was flowing with the river. Sting reached in his pocket and pulled out his guitar pick. "I really like music because of the feeling it brings on people. I enjoy coming here because it sounds so natural and serene. Some think I like rock or something like that, but I really like all kinds of music and want to share it with others. The only person I told that is Rogue."

"That sounds so sweet. So, why are you telling me?" Lucy asked.

"I thought if I told you a little secret of mine, you might tell me yours." Sting said. Lucy now felt stuck. "You're always disappearing and coming up with some excuse. You know you can tell me the truth, Lucy. If you're still in love with Natsu, I'll get it. I just want you to be honest." Sting is reaching out to Lucy, being considered, and wants to be who Lucy can turn to with secrets.

"The truth is...what I can't tell you, Sting." Lucy claimed and complete devastated Sting when she still refuses to tell him the mere truth.

...

Black Knight

"The truth can be so hard to get. It be much easier to just take it." Black Knight said as he could feel Sting's devastation. He decided to try both of his powers at once. He took one spiria in one hand and one etherious in the other. He infused both powers into them and unleashed them both. "Go forth, my evil etherious and spiria. Combine your powers into one!" He was unleashing both of them at once and added twice the danger.

...

Sting

As Sting stood there with a bit of his heart cracked, the etherious and the spiria went into his guitar pick at the same time. When that happened, the outline of both signs appeared over Sting.

"Truthseeker, I am Black Knight. She won't share her biggest secret with you? I am restoring your power to force people to tell the truth."

"Truth can't be forced out, Black Knight." Sting said as he tried to resist.

"Black Knight?" Lucy questioned when she realized what was going on. "Sting! Please resist him! I'm sorry!"

"Don't you want to know the secret she is hiding from you? She clearly doesn't trust you." Black Knight said.

"Lucy does trust me." Sting claimed.

"I do." Lucy said.

"If she loved you, she would tell you the truth no problem. She's clearly hiding something that she won't even tell you. You don't want there to be secrets between you, do you?" Black Knight said. Sting tried his best to resist, but Black Knight got into his head rather well.

"Run, Lucy!" Sting said as he gave in and was transforming. Horrified at what she's done, Lucy ran off as Sting became Truthseeker once again.

"To aid you in this mission, I have taken your desire to know the truth and gave it form." Black Knight said as a giant ball of light was formed right over him. "You will be able to control it and paralyze people with it. Just be sure you get the truth out of Celestria and Salamondra as well." This wasn't looking good at all and Lucy had to do something.

"I've got to save, Sting." Lucy told Stella. "Stella, Twinkle!" Stella was pulled into her earrings and she became Celestria.

...

Gajeel's Boat

"Later, guys." Levy said as everyone was starting to clear the boat after the performance. That was right when a light shined down on her and kept her from moving. Truthseeker showed himself and fired a shot of light right at Levy and now compelled her to tell the truth.

"What is Lucy's secret?" Truthseeker asked.

"She's in love with Natsu." Levy said.

"Not that secret!" Truthseeker said as he had his ball of light shine one on Erza now and used his powers on her. "What is Lucy's secret?"

"She loves Natsu Dragneel." Erza said.

"No! That's not it!" Truthseeker said just as Celestria arrived and kept herself hidden so she could contact Salamondra.

"Salamondra, Black Wizard has learned to combine his powers with the unicorn miraculous and is now calling himself Black Knight." Celestria said in her message. "Hurry and get here!"

"Sting? Is that you?" Rogue questioned. "What are you doing?"

"I'm learning Lucy's secret, but not that one about Natsu." Truthseeker claimed.

"But Lucy doesn't have any other secrets. She's the nicest honest person there is." Lisanna claimed.

"Or maybe she hasn't told you a bigger secret." Truthseeker claimed. "She must have told someone her biggest secret and the truth about it will come out."

"Sorry, Truthseeker. Sometimes things are just better left unsaid." Celestria said as she showed herself, but she played right into his hands. Truthseeker's light shined right on her and kept her from moving. Once that happened, Truthseeker didn't wait as he shot Celestria with his powers and now she is force to tell the truth.

"Time for the biggest secret to be revealed. Celestria, who are you really?" Truthseeker said.

"I am..." "A great swimmer!" Salamondra showed up just in time as he tackled Celestria right into the river and allowing them to escape. Truthseeker looked for them, but they were already gone.

"Find them!" Black Knight ordered. "Now that Celestria is under your power, this is the best chance to learn who she really is!"

"Don't worry. I'll send my light to find them and keep them paralyzed until I get to them." Truthseeker said as he sent it after them. "Until then, there's another secret I have to find out." He said as he took off to learn Lucy's secret.

"Fine, but make sure you learn what I want to know." Black Knight ordered with them soon going to learn they'll be one in the same.

...

Celestria and Salamondra

Thanks to Salamondra, they were both able to escape as they climbed out of the river.

"That was close." Salamondra said. "You think you're still under Truthseeker's power?"

"I'm sure of it." Celestria said. "This spell will only fade once we defeat him." A tempting situation for Salamondra, but he knew better. Celestria couldn't take chances as she pulled off Salamondra's tail and was planning to use it as a gag for her mouth.

"You could have just asked. Before you gag yourself, any idea as to what we're going to do or what Truthseeker is after this time?" Salamondra questioned.

"Truthseeker will be heading towards Heartfilia Bakery." Celestria said. "You can't use your Salamondra on that ball of light because it was formed by the unicorn miraculous and it might not even be a solid mass. We need to stop him before he learns of something he shouldn't." She said and then tied his tail around her mouth to keep her from saying anymore.

"Heartfilia Bakery? Weird. Lucy Heartfilia seems so nice. Hard to imagine anyone having a problem with her." Salamondra said. Just then, they spotted the ball of light coming for them. They quickly hid from it and got moving before Truthseeker can learn anymore secrets.

...

Heartfilia Apartment

Jude and Layla Heartfilia were just having a relaxing evening at home, but that soon ended. They were quite shocked when Truthseeker came crashing into their apartment. He fired another shot and it hit Layla.

"What is Lucy's secret?" Truthseeker questioned.

"Lucy? Her biggest secret would have to be her being in love with that Natsu boy." Layla said.

"Argh! That's not much of secret! The only one who would not know is Natsu himself!" Truthseeker complained. It seemed like no one might know, but there's another way to keep secrets. "Does she keep a diary?"

"Yes. It's somewhere in her room." Layla said.

"Perfect. That will tell me what I need to know." Truthseeker claimed as he was about to be on his way up, but Jude stood in his way. "Don't make me laugh." After a moment, Celestria and Salamondra showed up and saw that Jude Heartfilia has been flipped around with Lucy's room accessed. Salamondra was ready to go right up there, but Celestria had another entrance. Meanwhile, Truthseeker was searching around for Lucy's diary or anything that could tell him her secret. What he didn't realize was that the Miracle Box, Lucy's big secret, was quite close.

"He's going to find the miracle box." Roar, the lion kwami, said. "Black Wizard will know where we are."

"Not if I can help it." Moon said as he was going to try and stop him, but Pixi stopped him.

"You can't. A kwami can't use their powers without a holder or there would be catastrophe." Pixi warned.

"So we have to choose between the end of the world or the possible end of the world?!" Bull, the minotaur kwami, questioned as this wasn't looking good at all. Truthseeker looked around the room and spotted her desk. He was about to open it up and find the Miracle Box, but that was right when Celestria and Salamondra came in through the window and she used her whip to pull his arm away.

"Don't you know you shouldn't be snooping through a girl's room?" Salamondra said. Truthseeker tried shooting them with his powers, but they both jumped out of the way.

"You might think you got away from my light, but it will be here soon." Truthseeker said. "You can't hide the truth forever." He claimed as he started throwing furniture at them. As they were dodging, Celestria tried to tell Salamondra about the pendent around him.

"I know. That's where the etherious, and probably the spiria, is in." Salamondra said just as Celestria got hit. Salamondra came at him with his staff, but Truthseeker kept avoiding him. Truthseeker gave him a powerful kick and knocked Salamondra into the wall.

"Any time you want to use your power might help." Salamondra said, but she pointed she can't talk or else risk revealing everything. "Go ahead and take it off. I got it covered." Salamondra told her and she just had to trust him. She uncovered her mouth and readied herself.

"Celestria, what..." "Your top three traits you admire about Salamondra?" Salamondra interrupted as he tackled Truthseeker, but Truthseeker knocked him back.

"I would have to say it's his courage, his optimism, but I would have to the trait I admired the most is how he doesn't appear to be afraid to say what he really thinks." Celestria said as Salamondra really liked hearing that.

"Is that so?" Salamondra said as he kept trying to fight off Truthseeker. "Well, what do you think it's time to open up?"

"Open the Celestial Gate!" Celestria was able to call on her powers. She ended up getting a roll of Virgo aluminum foil. She looked around to see how she could use it, but couldn't find anything.

"Any time now." Salamondra said as he tried to hold back Truthseeker, but Truthseeker used the opportunity as he fired another shot and now placed Salamondra under his spell.

"Salamondra, what is..." "Your opinion of me being Guardian!" Celestria said as she threw a trash can right at Truthseeker to keep him from talking.

"As long as it doesn't change a thing between us, I'm fine with it. You're better fit for the role anyway." Salamondra claimed. That was right when Truthseeker's ball of light showed up and was right out the window.

"I have you now." Truthseeker claimed as he just needed to freeze them to get them to talk. That was right when Celestria got the idea as she looked at the foil and the ball of light. Just as the light shined on them, Celestria opened up the foil and used it to reflect the light right at Truthseeker and froze him with his own power.

"Dragon Fire!" Salamondra used his power right on Truthseeker's pendent and freed both the etherious and the spiria.

"No more evildoing for either of you." Celestria said as she activated her whip. "Time to de-evillize!" She threw her whip and was able to catch both of them. "Gotcha! Bye-Bye, little guy and little horsey." She said as she released both of them. "Miraculous Starlight!" She threw the foil in the air and the magic stars were released with them restoring Lucy's room to normal and breaking Truthseeker's spell over everyone. That ball of light also vanished with Truthseeker becoming Sting again.

"What am I doing in Lucy's room?" Sting questioned.

"Pound it!" Both heroes celebrated.

...

Black Knight

"The truth about who you are will come out eventually, Celestria." Black Knight claimed. "Now that I have my renewed powers and abilities, this is far from over. I will find you and the miraculous!" He claimed. He might not know how close he came, but he's not giving up either way.

...

Celestria

"Well, even if you are the Guardian, I'm glad to see not much has changed." Salamondra said as the two heroes made their way over the rooftops. "Seems like it was just another typical and normal day for us."

"If you think fighting a ball of light with a supervillain that nearly exposed our secret identifies normal." Celestria said.

"Seems like lots of new things are coming like Black Wizard now calling himself Black Knight. The name does sound more menacing and makes things a bit more interesting." Salamondra said.

"He can change his name all he wants. He'll still never win." Celestria said as neither of them are giving up either. With Black Wizard now Black Knight, and the miraculous were dangerously close to being exposed, they'll have to fight harder than ever. However, that meant one thing for Lucy. When the two heroes went their separate ways, Lucy went to talk to Sting.

"I'm sorry." Lucy said. "I can't tell you the truth, Sting. All I can say is that it's something I can't give up because it's really important. It's not really fair to you, so maybe we should..." Lucy felt bad and thought Sting would be angry, but he surprised her by wrapping his arms around her.

"When you are ready to talk, I'll be there." Sting said. Lucy hated that she had to do this, but she had no other choice. As long as she's with Celestria, she can't be with Sting. Maybe she can't really be with any guy. Sting was upset about this himself, but all he could really do was just trust Lucy. When Lucy was finally up in her room, she was free to cry all she liked.

"As long as Black Knight is around, I can't have a boyfriend." Lucy said as she stared at her photos of Natsu and Sting. She can't be with either of them because her being Celestria will always get in the way. She might never find love as long as she is Celestria and it was heartbreaking to her as she kept crying.

"Look! Water is falling from her eyes like humans do when they are sad." Finn, the shark kwami, pointed out.

"Good heavens. What do we do?" Christi said.

"Just give me a hug." Lucy said as all of the kwamis hugged her. She might not find love, but at least she won't be entirely alone and that's the truth.
