Fairy Tail: Crime Unit(Nalu, Gale)

Chapter 7

A/N: Sorry this took forever to post. This chapter took a lot of thought. <3
Natsu and I sat at the bar, drinking coffee. He was explaining everything Fairy Tail was and did.
"Fairy Tail is apart of an FBI branch made up of 'Guilds'. The Guilds specialize in the Black Market, and terrorist attacks. The FBI assigns each of the guilds a certain list of missions, fit for the skill of that guild." Natsu finished, taking a sip of coffee.
"How do you become a member of a guild?"
"Well you have to be chosen by the Head of the Guild. A lot of missions are challenging and you have to be willing to put your life in the line, so they put you through a series of test." Natsu took his last swig of coffee. "Come on, I'll give you a tour."
We walked through the lobby into the first corridor, which was filled with doors.
"This isn't really Fairy Tail. Think of it as a hotel just for Fairy Tail members. Each room has got a mini fridge, bathroom, microwave, stove, and sink. But we usually eat at the bar." We continued into the next hallway.
"This is where our Head of Guild, Makarov, stays. Then there's the conference room for the S-Class Members." He continued on to next room.
"Wait- what's a S-Class Member?" I asked.
"Well, it's like and 'elite title' that means they are better. They're stronger, faster, and have completed more missions. They are held higher then most members and are like the representatives of a guild. Ezra is one, and she takes great pride in it." Natsu smiled brightly.
"Are you an S-Class?" His smile vanished.
"Uh, no." I pursed my lips.
"Sorry I-" Natsu quickly turned and continued the tour.
"Next room is a file room. We keep brief files of each member at all our hotels. We also have a record of all our current  missions. For example, the mission that brings me and Gray here, is sent to this building so we know who is working it and that they are here," I remembered the first time I met them. They had sunk into my house.
"We've got business to take care of." 
"Natsu? Why does your 'mission' involve me?" I noticed he visibly tensed.
"What do you mean?"
"Well, that day, Gray said you guys had 'business' and you guys ended up unknowingly at my house. If you're in mission that involves me, I deserve to know what exactly your mission is,"
Just then, the conference room opened,
revealing a certain red-head.
"Ah! Natsu glad to see you, Gray was just about to ca- what is Heartfilia doing here?!" Erza all but screamed.
"Would you be quiet?Gray's gonna hear you!" Natsu growled.
"Too late." We all turned to see a raven haired figure at the door.
