~Lucy's Pov~ 

Everyone was so busy teasing Levy and Gajeel that no one noticed Juvia and I left the room. We were walking around as I was helping Juvia with her job. She worked with teaching and cleaning. She was meant to clean the weapons during lunch to give herself spare time tonight. I didn't mind helping out, everyone here was putting their lives on the line to protect me, I had to do something in return. Plus growing up with three men, I was normally the one to clean up with some help from Sting once and awhile.

Though when he helped out we would mess around more than clean. It was silly but was fun times. "Lucy-Sama, how did you convince Natsu-Sama to become your demon?" Juvia soon asked looking at me excited a light in her eyes. I rubbed the back of my neck with a small laugh. "Honest truth, he was the one who offered it to me" I answered as Juvia was in utter shock. She was begging me for more information about it. She was all excited soon explaining how rare it was for a royal demon to offer themselves to someone who wasn't their bride.

"I am not sure on why Natsu offered it to me but it was a deal to make sure I wasn't a pain in everyone's butts" I giggled as Juvia did also. She was soon telling me stories about Natsu and Gajeel. The two would end up fighting or/and be arguing most the time. They would be calling each other names and act very childish about things too. I only laughed at the stories as we got to the weapon vault. Juvia put in the code as the door opened to show an empty room. Juvia soon was freaking out worried and scared, rushing inside. 

She was looking around for anything as I was worried. "Natsu" I called knowing he would rush to my side fast. I went inside with Juvia who was soon scared that she would get in trouble. "Lucy what's-" Natsu stopped himself as he came inside as I was helping Juvia calm down. Natsu was soon asking Juvia what happened as I noticed Gildarts and Jellal with him. Juvia was explaining she locked the vault last week and only came to clean them today to see them missing. Gildarts looked calm while Jellal had a worried look on his face.

Natsu had a really upset face. "Block off all exits and communications, I want these weapons or the mole found" Gildarts ordered Jellal who nodded, rushing off as Juvia was soon blaming herself for not checking on the weapons sooner. I looked at Natsu who sighed and gave out an annoyed 'tisk' as he normally did as he walked over. "Juvia you aren't the only one with the code, don't blame yourself, we believe you didn't do anything" Natsu soon spoke as Gildarts looked slightly shocked but soon smiled. 

Juvia ended up hugging me as it wasn't long until a crowd was being built outside. Gildarts we giving off a speech while keeping everyone out. Natsu was sniffing around the vault as Juvia and I was asked to stay inside the vault until the crowd had cleared. "MOLE?" we heard people shouting outside in shock as Juvia was calming herself down slowly. I looked at Natsu once more as he soon let out an annoyed 'tisk' again. "They wiped the place down clean to block my tracking" Natsu muttered his eyes flashing red.

"Natsu" I spoke as he soon looked at me, giving his full attention. I soon asked about this 'mole'. Natsu rubbed the back of his neck. "For a while, we noticed information has been leaked to the Darkness but we thought it was something small like overhearing or something. Lately, we noticed important information got one of our bases nearby was leaked getting it destroyed, many people were killed but this just proves, even more, there is a mole inside our group" Natsu soon explained with the short version.

Juvia was starting to shake in place. "W-why would one of us help the Darkness?" Juvia asked her voice cracking at the start. A mix of fear, rage and sadness grew in her eyes. Natsu rubbed the back of his neck unable to say a thing. Seems not everyone was allowed to know. I heard people asking the same type of question outside the vault as Natsu was soon looking around the vault once more. "How many people have the code for this room?" I soon asked as Juvia was counting in her mind, using her fingers also.

"Ten, twelve when including Natsu-Sama and Gildarts-Sama" Juvia answered as I nodded and started thinking. There were too many possibilities about all this. There was a chance someone stole the code from another. There was a chance or people using spells to force open the vault. There was even a chance of more than one mole. "Lucy, you are not allowed to leave my side until we find this person" Natsu soon spoke while sniffing around the vault. Juvia was trying to keep herself calm as I heard the crowd outside calming down.

Gildarts and Natsu would never betray anyone here. Juvia, I just had a feeling she wasn't the person who did this. Nine others. "Who else has the codes?" I asked as Natsu then informed me he would give the list later. Why would the mole strike like this? It made no sense to steal our weapons unless an attack was incoming. "Natsu-Sama, what if someone attacks us?" Juvia asked in a worried tone as if she was reading my mind. 

Natsu sighed, giving us his attention once more. "Most of us high ranks don't need weapons to fight so we will be the ones defending the base" Natsu soon answered as Juvia let out a sigh of relief. Gildarts came into the vault asking Natsu for a small report. Natsu only rubbed the back of his neck. "No scent, this person knows how to block a Demon Dragon nose but my sight picked up at least two people were in here not long before Juvia and Lucy" Natsu soon answered as Juvia and I looked at each other.

We both were trying to think if we saw anyone go past us or anything that could have been helpful. Sadly we both came up empty. Gildarts soon left the room taking Juvia with him for questioning. "Natsu...I still don't get this myself but I just have a strong feeling Juvia didn't do this" I soon spoke as Natsu raised an eyebrow. He asked if it was like that feeling I had with Gray beforehand. I only nodded as Natsu started thinking. Aquarius told me to always follow my gut feeling, that it was linked to The Great Power. 

"Let's head out and get that list" Natsu only spoke leaving the vault. I only followed as the crowd was gone. Gray and Erza were waiting outside with Jellal. "A mole, rare thing and annoying" Jellal spoke as Natsu nodded in agreement. He soon was asking Jellal if his team was due. Team? Jellal only smirked slightly and closed his eyes. "Yep all due to be back. This mole won't last very long now they've done this" Jellal replied as Natsu nodded and soon reminded Gray and Jellal not to tell a soul about the peace between Hunters and Rebels.

Erza was in some shock but soon Natsu was asking why she was here. "I am to be Lucy's extra personal guard with Gray being busy with making this treaty" Erza answered as Natsu gave out an annoyed 'tisk' in reply. He really liked making that noise. I rubbed the back of my neck. A mole. At a time like this. I had to hope the information about me wasn't known. "Natsu, be nice" I ordered as he rolled his eyes. Jellal chuckled crossing his arms. Natsu gave him a glare as Gray sighed, shaking his head. 

"Is it wise to have me and Erza around while a mole is lurking?" Gray soon asked shocking me and Erza with his question. Natsu looked toward Jellal. Jellal's smirk had turned into a smile as he opened his eyes. "It will be fine, the more manpower we have with defending the base the better anyways. Weapons being taken means an incoming attack" Jellal answered. This only worried me. I was starting to have a really bad feeling about all this.
