I'm gonna stick to what I said, It will only be a Natsu x Rias. Issei will get a small harem that will include. Akeno, Asia, Koneko and Irina. And Kiba will end up with Xenovia.

Chapter 4

Natsu starred blankly at the wall in-front as thoughts started filling his mind. "Rias looks like someone I know" he thought. "Natsu!" Serafall shouted excitedly. "Oh hey Serafall" Natsu turned to meet the short girl. The overly energetic girl pounced on him and hugged him tightly. "How is my favourite bishop doing?!" She asked. "I'm doing fine" he answered. "So what's this about Rias looking like someone you know?" She asked, getting off of the pink haired boy. "Did I say that out-loud?...someone from my old world...all though I don't remember them, when ever I see Rias I am faintly reminded of a person who was very dear to me..." Natsu explained, standing up and dusting himself off. "Was she your wife?" She seriously asked. Natsu's face turned crimson "n-no...besides I'm sure that I'd remember my wife, if I had one"

"Okay Natsu today is your first day of school in the Human realm...luckily we've been able to get you into the same class as Rias, and Akeno...don't do anything frisky with the two" Sirzechs said as he winked, and chuckled. Grayfia smacked him upside the head. "Have some decency..., I can't believe I'm saying this but, I'm gonna miss you and your annoying antics Natsu, you've really brightened this place up!" She stated smiling. "..." everyone was at a loss for words. "D-did she just smile!!!" Everyone shouted. Sirzechs laughed again "she only ever smiles like that when I've satisfied h-" the crimson haired man was cut off, as he was frozen solid. Grayfiya's face went crimson, with an angry expression on her face. "Fool!" She yelled, unfreezing the man and encasing her fist in ice to strike him in the jaw, sending him into the table as it crashed under his weight. "Natsu, I'm gonna miss you too...and the sight of your body" Venelana whispered the last part under her breath. "Natsu my boy, you've brought a lot of good times to this household. You've made us laugh, you've made us smile, and overall your presence improved our daily lives. It will be saddening to see you go, but I know you'll visit all the time. So protect my daughter, and be safe Salamander" Lord-Gremory stated as he brought the boy into a hug. At the mentioning of the name of said animal Natsu's mind went into a flash back, where he saw a man with long-spiky black hair, and red eyes. "Salamander?" Venelana looked at her husband. "Yeah it's a nickname I've just thought up for him, cool isn't it?" He looked back at her and grinned. "Dragon seems more befitting, and cooler" she claimed. Everyone's words made Natsu really happy, as he smiled. "Goodbye for now everyone!!! Im gonna miss you all!" He stated. Serafall stood their with tears in her eyes "do you really have to leave...?" She asked him. "Yeah...but it's okay I'll always visit, especially on the weekends to train with Grayfia, that was our agreement after all!" He revealed, as he grinned, and gave her a head pat. "Besides, you're a powerful devil, you can always just visit me whenever!" Natsu stated as his frame began to glow in a brilliant light. "Goodbye all of you! Thank you for being so nice, and patient with me! I will never forget what you've all done for me!" Natsu lastly stated as he completely faded away

[A/N: Natsu and Serafall are best friends, they do not share romantic feelings, Also the reason why Natsu gets flustered around naked woman is because he lost all of his memories, this includes all the times he showered with Erza, which is the main reason why he was so nonchalant around woman]

[2 years later]

[A/N: no it didn't take him two years to travel to earth, Lol. I just decided to do a time skip, he falls out of the air very often]

"...not again, AHHHHHHHHHHHHHHHHH" Natsu screamed, as he rapidly fell from the sky. "Hey does anyone hear scr-" Rias could not finish her sentence as Natsu had fallen on top of her. "T-thanks for breaking my fall..." Natsu stated, starring at her well endowed chest, as if he were speaking to them. "Owwww" Rias stated, laying under a sitting Natsu. "Oh my...I thought the woman was typically at the top" Akeno mentioned in a sultry tone. Natsu, and Rias's faces flared up in red. "D-d-don't say stuff like that!" They both shouted in unison. Natsu got off Rias, and offered his hand to help her up, like the gentlemen he is "Wow Natsu, you're so chivalrous like a real man!" Koneko stated. The words "Like a real man" played on in his mind. As he pictured a behemoth of a man with white hair and blue eyes. "Hello Natsu...you there?" Rias says, waving her hand in-front of his eyes. The light seemed to come back to them, as he looked her in the eyes. "W-what's wrong Natsu?" She asked. Natsu's eyes phased reptilian, as his ears perked. "Some boy is being attacked...by what seems to be fallen angels." He revealed. "What? How do you know" she asked him. "I can hear him struggling, the poor boy is powerless. We have to help him!" He stated as yellow lightning began to spark around his form,and he disappeared. "Powerless boy? That must be the boy with the sacred gear" Rias proclaimed. "Wait where did he go?" She asked. "D-did he just use lightning?" Akeno asked..."that's my thing!" She stated afterwards.

"Thanks Issei, I really had fun today!" A black haired girl with purple eyes stated graciously. "Uhh...no problem, I'm really glad you had fun today...maybe we can go out again the next time you're free?" Issei asked rolling the dice. "For sure!" The girl smiled. "Can I ask you a question? In honour of our first date, there's something I'd like you to do. To commemorate this special moment." She stated hopping closer to him with each syllable. "Sure you can ask me anything at all." "Would you die for me" she asked sinisterly her tone of voice changing. What do you say, sorry something may be wrong with my ears I don't think I heard you correctly, could you say that one more time?" He asked the girl, shocked by the abruptly dark question. She walked up to the boy and spoke into his ear "I want you die for me." She repeated, as she cackled. Her form began to change, "BOOBIES!" Issei thought to him self "today is the day I became a man" be thought to himself she grew taller and jet black wings sprouted from her back. "She looks like a demon...are those wings?!" He asked him self in fear as he fell on his ass. "Well I have to admit I did have some fun today considering how naive and childish you are things could've been much much worse. Thanks a lot for the gift too, very sweet, but even so" she stated, as he palm began to glow red, and the light expanded outwards in a thin line. "Yumma wait, please" he pleaded as he reached his arm out. "It's time to die!" She stated as she thrusted the glowing spear into his abdomen, piercing it causing blood to spew out. He placed his hands over his fresh wound as he fell on his back. "I'm sorry, but the fact is. You are to dangerous for us, I had no choice to dispose of you. If you're looking for someone to blame, why not blame him he gave you the sacred ge-" all the sudden yellow lightning began to spark in the sky as 4 strands of lightning developed, they all met colliding as they struck down swiftly. Out of the lightning came a pink haired man "w-who is he?" Issei asked him self, his conscious fading. The blurred figure looked back at the boy, then the enemy. "Shit I'm too late!" He frowned. "Who are you dev-" the fallen angel could not finish her sentence as the man vanished from her sight, and just as quickly appeared in front of her. He implanted his fist into her gut with so much force, she spit up blood and her body bent backwards. She flew off his fist so fast, she disappeared from sight. With much greater speed, then the flying girl. The pink haired man appeared above her and swiftly brought his foot down on her abdomen to connect with a brutal axe kick, that sent her into the ground "such speed" she stated, colliding with the ground with such force, that a medium sized crater was formed under its pressure, and she coughed up blood yet again. "Is that a dragon...?" Issei asked before loosing consciousness. The pink haired boy stood over the unconscious body of the female fallen angel. "She's kinda hot" Natsu then appeared before the unconscious boy and saw his gaping wound. "Shit, I have to cauterize it to stop the blood flow!" Natsu stated as he brought his engulfed flame to the wound, closing and sealing it. "Goddamnit, Rias where are you!" Natsu asked to the heavens. A red magical circle began to form in thin air, Rias had appeared. "Natsu...what happened!" She asked. Natsu pointed at the still unconscious fallen angel. "Rias, I closed his wound. But at the cost of a nasty scar..." he revealed. "It's fine Natsu you've saved his life, besides it's nothing a kings healing couldn't f-" Rias' was cut off as a white spear was plunged through her chest. "RIAS!". "Hahahaha, I couldn't believe it was that easy. I just took out a Gremory, and you're next boy...huh where did he g-" Natsu appeared behind the man, fury evident on his face, he brought his foot up and delivered a fatal wheel kick to the man's neck, which held enough force to swipe the man's head clean off, blood spewed from the fallen angel's neck as he fell to the ground dead. Natsu held rias within his grasp, as tears began to form under his eyes. "N-Natsu?" Rias weakly stated, as she brought her hands up to wipe his tears. "It's okay...you'll just have to heal me" She stated as she fell unconscious.

"Where am I?" a black haired man asked himself aloud. "Surely I am not alive!" He stated. "I couldn't have possibly survived the destruction of the entirety of the universe! Does the curse have no limits?!" He frantically asked him self. "Am I dreaming...if I am that would mean I'm lucid dreaming, perhaps I shall call out her name...Mavis if you are there show your self to me!" The black haired man asked, now finally taking in his surroundings. "You are not dead" a random voice said. "Huh, where am I, and who are you?" The man asked turning to look at the other. The man had an angelic appearance as 5 lucious pairs of pure white feathered angelic wings sprout from the man's back. His hair platinum blond in colour and his eyes a soft green, a halo adorning his overall appearance. "You first sir" the platinum blonde asked. "I am Zeref Dragneel, now tell me where I am!" He asked. "You are currently in the divine realm...or heaven, and I am ArchAngel Michael head of the angel clan!" The man revealed his identity. "What how did someone like me end up In heaven?!?" Zeref shouted

THE END:

I hope y'all enjoyed this chapter, sorry for taking so long, I know it doesn't make up for it. But I decided to make it a juicy one! How will the appearance of Zeref change the story?!? Is his curse still intact or was it indeed removed because of the neo eclipse!

Current Power Levels:

Sirzechs: 17500

Michael: 17500

Serafall: 16000

Zeref: 15000 (he doesn't have fairy heart currently, he'd be way too fucking OP. He may unlock it afterwards though, as it does have a divine appearance)

Grayfiya 12500

Natsu (base): 10000

Rias: 9000

You'll notice that everyone underwent a major power spike, that is simply because of the time skip. Just to be clear, Natsu alternates between training with sirzechs, grayfia, and sometimes Rias.
