-------Mirajane P.O.V----------
My name is Mirajane Strauss and I am a S-class mage of Fairy Tail. I decided to bring my little brother Elfman and my little sister Lisanna with me on a S-class mission. Natsu wanted to come with me but I didnt want him to get hurt and besides its just a simple beast extremination quest, what can go wrong. However, I probably shouldnt have thought that because when Elfman performed a take over on it, he lost control and started attacking it was about to hit me before Lisanna stepped in front of me with her arms extended.
"Elf-nee-chan, its me your little sister Lisanna and your older sister Mira-nee."Lisanna said as she tried to calm him down. Elfman however started hesistating. "Thats right, Elf-nee-chan. Come back to us." She continued saying but Elfman started to go through the motion of a punch. His fist was right about to hit her until her and Mira heard a voice.
"Time blast." the voice said as Elfman was suddenly engulfed in green light that froze him in place.
---------------Mirajane P.O.V end-------------
--------------Mars P.O.V return-------------
'Whew, almost didnt make it in time. Grayfia, Thunder, and Mavis should be at the Guild by now. I hope Makarov is guild master he deserves it. Now to deal with this.' Mars thought as he moved the frozen in time Elfman, who was still in the take over state,5 feet away from the Strauss sisters.I turn my head to them and said "My name is Mars Gremory, S-class Mage of Fairy Tail since x715, the current First God of Ishgar and a pure blood devil. Before you even ask, no Im not created by Zeref, I am nothing like those fakes." He turn his head back to froozen Elfman and unfreezes him and says "You know, you almost killed one your little sister. So unmanly. So very unmanly." Elfman who heard this regains control and reverts back to his human state. He looks at his sisters and starts running to them, crying, while saying sorry a bunch of times.
The three, especially Lisanna, comes over and says "Thank you....Mars, was it?"
"yes, it is indeed Mars." he replies with a smile.
Mirajane as the 4 were now headed to guild after they recieved their reward of 15 million jewel asks him "So, if you were made S-class in x715 then how come you were never in the guild and how come I have never heard of you?"
He smiles and says "well to answer your first question, I took a 100 year quest 52 years ago and to answer your second question....whose the current guild master?"
Elfman chimes in and says "Master Makarov."
His smile grew wider and says "so little Maki finally became guild master, huh."
Lisanna, who heard this started laughing. Mira was trying to hold in her laughter. While Elfman started saying how unmanly that was...suprisingly enough. Mirajane who had calmed down decided to ask "you said you were on a 100 year quest, could you tell us about it?"
His smile faded and just simply nodded as he began to tell them what happened on his 100 year quest. The Strauss simblings were shocked when they learned that he was dragon slayer like a certain pink haired white scarf wearing mage that they knew, but were even more shocked to learn that he was strong enough to kill 5 dragons. He suddenly remembered something and said "Oh I almost forgot that the reward was 750 million jewel." At that point the Strauss siblings had fainted right then and there. Once they recovered from their shock, they boarded a train and headed to Magnolia.
A few hours later and they arrive in Magnolia, the 4 started walking to the guild but Mars stopped at a bakery and came out with two pies in hand. The strauss siblings especially Mira, came forward and asked "Really? Pies?"
He responded "Yes, one is for my bride to be and the other for me. Althought she will never admit, she has a sweet tooth and no Im not talking about this Erza that you mentioned back on the train. Im talking about one of the other S-class mages that I brought with me on the 100 year quest. Her name is Grayfia Lucifage, wielder of ice. Back in my world, dont ask, she and another ice wielder woman are fighting to be the "main girl" although I dont mind them fighting, I just dont want either of them to get too hurt." They nodded at his words.
Once they reach the guild Mars punches the door open which causes both doors to be obliterated, at that moment the famous guild wide brawl stopped and everyone looked towards the newcommer. They all cheered at the return of Mirajane and her siblings, while suddenly a head of silver hair comes rushing over and takes one of the pies that Mars has and sits next to Erza and began eating the pie. 'Heh, cute.' He thought but was interupted by the voice of Makarov Drayer.
"So you've returned, huh, but what are you doing with the Mira and her siblings?" Makarov says.
"What thats it? no hi Mars-sensei, huh little Maki? Anyway I take it Thunder and Mavis are also here. To answer your question I was helping them complete their quest." He said to master Makarov.
"Alright then. Alright everyone, it's time to party!" Makarov said as everyone starts partying.
It was the next day, mars woke up and found himself in infirmary in the guild, but when he tried to move he suddenly hears a pair of soft moans. Wait a minute a pair? From his left, he saw a head of silver hair. 'This is obviously Grayfia.' he thought as he looked left he found a head of black hair in twin tails. 'Serafall? How'd she even get here to this universe?' Many questions were racing through his mind but was interrupted by a small figure entering the infirmary.
"Little Maki, what happened last night?" he said to Makarov.
Makarov looks at him with seriousness in his eyes and says "A lot of stuff happened last night. After you got drunk, you started going on and on about various stuff that may happen in 2 years and something about adding natsu and erza to your peerage."
He puts his hands on head as he remembers everything and says "Oooooh mou, this is way I hate drinking. Yes, everything I said is true. The peerage system was developed by my best friend back in my world after the great war between us, Angel, and fallen angels our numbers plummeted and after civil war they plummeted even further. Not too mention our horrendous fertility rate, we were on the verge of extinction with only a few thousand left of us when I left my world to gather my own peerage. The peerage system allows us to turn humans or if you have enough power the pieces will mutate and then you'll be able to reincarnated other races besides humans as a devil. All to replenish our numbers and before you ask no it does not mind control them. Look at Grayfia for example she has my queen piece. I hope that answers your questions that you have."
2 years go by quickly and after several various events, the Tenrou were now on the Tenrou Island. The first trials were now over everyone was now resting when Mars pulled Natsu ahd Erza aside and asks them "You both know the truth about me, I would like an answer to my question that I asked you both 2 years ago."
They both look at each other, nodded and say in unison "We will join your peerage. If events happen like you says they will then we will need to get stronger to protect our family and guild."
He smiles widely as a magic circle appears under him and says "Well then I, Mars Gremory, accept you both as servants of House of Gremory." Once he was finished speaking 2 mutated knight pieces go into Erza and 4 mutated Pawn pieces go into Natsu. Now that you both are members of my peerage it's time to go fetch my other pawn. Oh and Natsu if you want to bring Happy you can." Natsu was happy at this point. He grabbed Grayfia, Thunder and Natsu grabbed happy and they all entered a portal to the Bleach universe.
