A Demon's Creation
It did not take long for Natsu to be alone again, three weeks to be exact. Zeref's friends were just that, her friends not his friends, they left Natsu alone once Zeref left. After Natsu found this out, he quickly refused to speak with any of Zeref's friends and everyone in general except Zeref herself. He simply had to deal with the fact, he was a sick nobody that nobody cared to lift up a finger to help him, even hearing Academy lecturers advising Zeref to give up on him and pursue something else. Zeref was the only one that mattered in everyone's eyes, she was gifted after all.
3 years had passed since Natsu's solitude began, more than 2 of those years were used to help Zeref find a cure for his illness. Although they were very different in their research, while Zeref was trying to find ways of fixing the magic container, replacing it with another magic container. Natsu was figuring out ways to remove his magic container altogether.
Now 7 years old Natsu was forcefully matured with the maturity of a man in his 30s being able to conceive ideas not many people could. "Another failure..." Natsu grumbled a hovering lacrima life support system shaped like an upside-down pyramid, following him. "Hm perhaps I am not thinking of something basic, whenever I try to create living cells from my own body, they somehow collapse in on itself" Natsu rubbed his eyes. "Maybe I should try changing the genetic code once more... no I have made all changes I could think of, to remove my magic container, I need to remove magic from my cells but to remove magic I need to replace it with something of equal exchange" he sighed. "I should check if I missed anything" walking over to the book case Natsu started reading.
After several hours, Natsu threw the book he was reading on the floor with the rest of the information books he had. "Natsu" Zeref knocked on the door surprising him "just to let you know I am back from the Academy, I will just be in the bath if you need me"
"Yeah okay, just make sure you get some relaxation" Natsu called back, not really listening. "Maybe I am going about this all wrong, but the calculations say this should work so is it how I am doing it cells multiply with the added chemicals, they start to work until it nearly reaches halfway". Natsu went into a thinking position "what don't I have anatomy wise". He hummed 'compared to other men, the only difference is the broken magic container... this is getting me nowhere, I should just ask Zeref if she... wait she'. Natsu closed his eyes to not get distracted 'on a cellular level men and women are the same but genetically we are actually quite different half way'.
'Wait a second, I have been taking blood from my legs, below the waist of a male unless there is a genetic defect, the chromosome is always Y' Natsu pondered. 'A human does not have Y chromosomes above the waist, so which is why my cellular experiments have been failing, if I take the cells from my upper body, I will have X chromosome cells and hopefully they will multiply'. Natsu looked down 'the only problem is that my upper body has a majority of bad cells, I will need time to find some of my good cells and take them before they turn bad'
"Hey Natsu" Zeref whispered popping her head around the door. "Ah you are awake, that's good" she opened the door fully walking in wearing nothing except a white tank top and black panties.
"Yeah I'm awake" Natsu span around "do you need something big sis?"
Zeref shook her head in the negative "no nothing at all, just here to see how my little brother is doing". She bounced forward tackling Natsu gently onto the bed in a hug "so how are you feeling?"
Natsu hugged her back and rolled his eyes because his mind was still too innocent to realise, Zeref was grinding against him whenever she hugged him in private "I'm fine, nothing wrong I am just annoyed with research".
Zeref pulled her head back "what type of research?"
"Human cell multiplication and mutation" Natsu answered
"Do you need any help with that? It is a hard bit of research" Zeref asked putting her forehead on his.
Natsu closed his eyes to think "well can I have some of your cells, female cells are different after all".
"Sure, I would be happy to help" Zeref stopped her grinding "do you need to take my blood or what?"
"I need your blood or saliva or conceivable organ fluid" Natsu listed off.
"conceivable organ fluid? You mean my... uh" Zeref looked down with a frozen look "but I can choose the other options, right?"
"Any of the ones I listed..." Natsu started but was hit in the mouth with black panties.
Zeref spread her legs out and gave a thumbs' up "I'm ready".
Natsu shook his head, taking out a needle, he stuck it into her lower stomach and removed it once it became full of liquid "there finished". His answer making Zeref blink in confusion. "try to refrain from taking your underwear off next time" Natsu put Zeref's panties back on her frozen body.
"So... I didn't need to strip" Zeref dragged out
"Not in the slightest" Natsu gave her a perplexed look "why did you ever think you had to remove them? I never motioned for you to do it or anything, what gave you the idea?"
"Nothing at all, nothing... at all... ahaha I just spread my legs for my little brother to see my womanhood" Zeref laughed as if she lost her mind. "ahaha I can't get married to anyone else now and I can't marry my brother... what am I ever going to do?" Zeref wobbled her way to the door still laughing crazily.
Natsu raised his eyebrow 'sisters are strange, she is never like this except when she is around me'. He shook himself from that train of thought 'well now I have cells to use, let's see if it works'. Walking over to a large cupboard and opened it revealing a large capsule like shape bigger than the average adult. Natsu took out a small rectangle piece of glass and bit his finger to put a small bit of blood on it 'now if I mix a small amount of her cells to my blood' Natsu pushed the syringe slightly let a small drop of Zeref's cells to fall into the blood. 'Now I just have to...'
ten minutes later of working on the cells Natsu finally finished 'Now if I put these cells in the chemicals, I will finally be able to see if the cells will multiply together healthily so I can finally get rid of this illness'. Natsu put a free hand over his mouth as he had a coughing fit 'that lacrima life support system can only do so much'. He stared at his hand which covered his mouth with seeing the small bit of blood 'hopefully it won't matter soon'. Natsu moved back to the massive capsule and opened it, the liquid acting like a jelly, never poured out like a normal liquid would due to the magic which was placed on the capsule. He placed the glass rectangle with the cells on it against the liquid, allowing the cells to float into the chemical liquid and be absorbed the said liquid. 'Now all I have to do is wait' Natsu closed the cupboard to allow the cells to grow and multiply.
(Time skip)
It had been a week since then and Zeref was leading Natsu into the magic Academy. While normally Natsu would be unable to enter the Academy main building but Zeref had managed to 'persuade' the instructors with a threat to leave. However, that did not mean Natsu got better treatment than before from the instructors or any of the students.
"Don't worry Natsu, my study room is just up ahead, maybe you can make sense of the results and we can finally get you a cure" Zeref looked to her right to see Natsu's emotionless face turn into a small smile.
"Then we can play around like real brothers and sisters should" Natsu noticed Zeref was blindly staring at him.
"Or we could do even more" she spoke giddy under her breath with a light blush.
"Um Zeref" Natsu stopped walking, seeing Zeref had not stopped and fake coughed speaking louder than last time "Zeref".
She turned around his words getting her head out of her thoughts "yeah, what is it?"
Natsu pointed to a door with Zeref written on it "you walked past your door, not thinking straight or something?"
'Well does imagining an erotic moment with your brother count as not thinking straight' Zeref thought with a mental sigh. "No, I just wasn't thinking at all" Zeref spoke trying her best to not show any of her thoughts on her face.
(Meanwhile)
In Natsu's room, a figure was wandering around the room, brownish purple eyes picking up every detail, black hair dripping wet with a strange liquid "M-Marfft..." The figure strained out unable to speak before collapsing on Natsu's bed taking in his scent. The figure lifted their head confused "Aferf". It turned its head to the door "marrft". The figure pushed itself off the bed with a great deal of struggle and stumbled to the door.
