For those who are reading this, I do not own Fairy Tail

Prologue part 1

"Elfman, I still can't believe you're the same shy little softy that I used to know!" said an aggressive young women in gothic like cloths. "Now you're trying to act all high and mighty, talk about a load of sh" she was interrupted by Elfman shouting "MIRA!, I'm just saying that our Lisanna and Natsu seem a little closer to each other than usual. Normally I would beat the guy up over it but Natsu has proven himself to be more than enough of a man to be with her. "

Mira responded in her usual tone, "You better hope you're right, but if I find out Natsu has been trying to stick his XXXX anywhere near our sister then their wouldn't be anything left of him FOR A FUCKING CREMATION!"

Elfman gulped quietly and thought to himself, "Why can't Mira be nice for a change? After all there is a reason why she is considered The Demon of Fairy Tail, and it isn't just because of her take-over magic." After that he asked Mira while pointing out the fact he was in his pajamas, "By the way Mira, why are you asking me to spy on her in the middle of the night (YAWN)? Its twenty till eleven plus it's a Sunday for a Man's sake."

Mira turned towards him and quietly answered, "I thought I've been hearing Natsu's voice coming from Lisanna's room around this time every week and I just want to know if it means he is going to get an ass kicking from me or not."

The Strauss siblings finally reach the door to Lisanna's room when they heard a pair of voices that belonged to Natsu and Lisanna.

"Natsu" Lisanna moaned

"Lisanna" Natsu said quietly

"I knew it" Mira said quietly as her face started to blush.

With the assumption of them having sex in her mind she kicked to find….

Natsu and Lisanna with Happy rolled up in her lap muttering about an all you can eat fish buffet going on a "Fish-land Castle?" Natsu shocked to see Mira emanating a dark aura in shock to see that she was wrong.

Lisanna explained, "For some reason Happy keeps getting nightmares so I told Natsu and Happy they can sleep over on Sunday nights until Happy stops having these nightmares. After all it's only natural for a mother and father to worry about their child, right Natsu?" She then kissed Natsu on the cheek which caused his face to turn a pinkish red as he joked by saying, "Come on Lisanna, I don't think we need to drag Mira and Elfman into our family just yet".

Mira rolled her eyes thinking of how she managed to get Natsu into bed with her then use Happy as a convenient excuse as she responded, "You actually think this little excuse would be enough to explain why Natsu is under the covers with you, right Elfman….Elfman?" She looked to Elfman to only see a "proud" man sobbing as he says, "Natsu, you really are a man to look after your kid like this especially since he's my" Mira interrupted by say, "I can't believe you are falling for this bulls…" Mira stopped when she heard Happy mutter, "Aunt Mira, once we get back to Fairy Tail, can show me that finishing move you used to beat Erza, pretty please?" Mira noticed that he really was a sleep and that part about her finally beating Erza did sound nice and Aunt Mira did have a nice ring to it. "Okay they can stay, but just until Happy stops having those nightmares" she said thinking that this might be okay for them.

By then Happy finally woke up noticing that it is still the middle of the night. "Hi Elfman. Hi Mira, you guys wouldn't mind if I have some milk would you?" he asked with Mira answering his question, "sure why don't you go with Elfman, get some milk, and be sure to take your time so you won't have to go to later in the night, right Elfman" hinting him of what she has in mind, he nodded in response with Happy saying his usual "Aye" as he goes with Elfman for a late night glass of warm milk.

"As for me I'm gonna get dressed for bed and go to sleep. Oh and Natsu, be gentle with your wife now" she said before giving a wink and a goodbye for the night as she saw Natsu's face turn a shade of red as deep as Erza's hair.

Lisanna looked to Natsu and says, "looks like Mira has finally warmed you Natsu" he simply replied, "yeah she really has" they shared a kiss thinking that this can be how their future would be like.

After couple days have past and the Strauss siblings took a job for the guild out of town involving a monster called…

"The Beast"
