Seilah opened her eyes and surprised there wasn't any pain, she sat and saw she was all healed and her clothes were repaired from her fight with the Fire Dragon Slayer.
"How you feeling?" Natsu asked making her turn her head towards him, The Dragon slayer was standing 3 feet from her with crossed arms and a sharp gaze.
"Where's Kyoka?" Seilah frowned.
"Taking a nap" Natsu pointed with his thumb she looked saw a blackened and damaged area with a burnt Kyoka in the middle unconscious.
"She dead?" Seilah glowered.
"No she's not just injured but thanks to her she has some of your power and it's making her heal faster" Natsu told her.
"Why would she do that thought I could trust her and we were a couple" Seilah frowned.
"Ouch" Natsu responded "You see Demons like her only care about power and will do anything to get it, even if that means killing one of their own" Natsu said "Luckily I used a healing spell and has returned" he told her.
"Why did you save me" she wondered.
"Honestly I don't know" Natsu shrugged "I do sense some confusion within you, maybe there's something worth saving" he said "My Hellfire didn't really have an affect on you" he told her.
"The Hell it Didn't, it burnt me never felt fire like that before" Seilah scowled.
"yeah it's fire and yes very hot, but it didn't affect you like it did the psycho bird over there" Natsu explained "You see my Hell flames have special qualities to them, they burn the evil and wicked with the full brunt of Hell's fury so its 10 times more painful to them" he said "These flames sometimes activate automatically when those kinds of people are in front of me, when I felt your friends evil and wicked when I arrived I could feel the Flames of Hell stirring" he said.
"You see I believe in a few things those being: Justice, Righteousness and doing the Right thing" Natsu told her "But also believe in giving a chance to change" he said.
"why would I want to" Seilah glowered as she stood up.
"Well you don't have to wanting to change or not is up to you" "plus you look like you need a friend and I can offer you that a life of happiness and friendship, everyone needs a friend, even Demons oh excuse me Etherious" he corrected.
"How do I know you won't do the same?" Seilah sighed.
"Well it's wise of you to think that, now anyways" "but rest assured I'm nothing like that Etherious, because she's a real Demon and a nasty piece of work" Natsu told her "I can't say it will be a walk in a park on making friends, you have to earn a one's trust respect and friendship plus a bit of loyalty is nice to" he said.
He held out a hand "So my question to you: will you give yourself a chance to leave the darkness and live a life in the light?" Natsu told her.
Seilah thought about it carefully on one hand told her after Kyoka's stunt not to give a chance, on the other: a life with a real friend does sound nice, she exhaled thinking of her answer and grabbed Natsu's hand "I will" Seilah smirked softly.
"Good remember this: Every new journey begins with a single step and whatever that journey brings you stand tall and firm" Natsu told her "Now what to do to her" he said to himself and walked over to Kyoka seing she was almost healed, he then placed his hands they glowed Crimson and with a hard glare he burnt away Seilah's magic away, so it would seem but he store it in his flames and put them out and dark purple aura dance around his fingers he then walked to Seilah and placed his fingers with a hand on her shoulder transferring the rest of her power back to her.
"Lets put her back in the book, so I need a favor bring her book to me" "giving us both a favor actually and send her back" Natsu told her.
"Yes I'll be back Salamander-Kun" Seilah nodded and left, Kyoka got up minutes later Seilah disappeared. Natsu turned back to her with a glare.
"I hope your happy you killed your friend" Natsu said in a low tone "I set her spirit and body at rest" he said.
"it was necessary, all we care about is to survive" kyoka glared.
"No you demons like you care about nothing but yourselves, it's a good thing you have Seilah's Magic to otherwise that attack would've turned to a pile of ashes, then again should've put more in to it" Natsu told her.
"Shut up!" Kyoka screeched turning in to her Etherious form again and blasted at him but Nasu dodged her attacks and a blink he planted his right fist covered in Hellfire into her stomach hard then ducked a swing uppercutted her in the ribs and side, then sidestepped a swing placed a block on the arm and sent a jab and cross to her jaw then roundhoused her in the stomach followed by jumping with a spin slamming a hookkick to her chest sending her into a tree.
Natsu slammed a Crimson flamed fist into the ground as he jumped forward 10 feet the ground cracked and ruptured as Hellfire rushed through the cracks and exploded under the Demon in a large concussive blast of a giant bonfire of Hellfire consumed her ejecting her back through more trees burnt.
Kyoka got up then a righthook covered in thick amount of Hellfire was slammed into her jaw sending her skidding on the ground leaving a trench, Natsu kicked her in the face sending her smashing through huge rocks and trees.
Kyoka got up shaking her head as she endured the Flames of Hell "You can't beat me I'm Kyoka the Goddess of the Slave Planet" she stated.
"And I am the Prince of All Fire Dragons" Natsu shot back.
"And I'm Goddess of the Chill Moon" a irate voice called as a powerful righthook was launched into Kyoka's jaw shattering the helmet and sending her flying as a massive blast of energy same as the blast that hit Natsu slammed into her making more destruction and a demon in her human form, she looked and saw a furious looking Seilah in her Etherious form with a book in her arm.
"Seilah your alive" Kyoka said but Natsu could hear false emotion in her words both landed a punch to her face at the same time sending her head slamming on the ground cratering it
"No thanks to you" Seilah hissed with glowing solid yellow eyes as she slashed her with her clawed hands at an angle on her stomach and left chest and two punches to the face and head knocking her out "Rotten Bitch" she spat.
the two nodded at each other and chanted some words and sent the other Etherious back in her book, Seilah then took the book and threw it off the cliff and the two left.
Back at Fairy tail Natsu had been gone for awhile for a Errand as he said, then the door was kicked it open with a bang they looked and saw Natsu walk in.
"Oh there you are, got lost?" Makarov asked.
"Uh Gramps you believe in giving a chance right" Natsu scratched his head.
"Of course" Makarov nodded.
"Well may have found someone that wants to change" Natsu told him.
"Is the Iron Dragon Slayer?" Makarov asked.
"Not yet I have feeling he'll come soon" Natsu shook his head "alright to can come in now" he looked towards the door and a figure walked in, and it wasn't Gajeel it was a very beautiful woman in a Kimono with golden horns on the side of her head.
"Oh hi miss" Makarov blushed at the sight of the woman who walked in.
"Don't be shy" Natsu told her.
"Hi I'm Seilah Goddess of The Chill Moon" Seilah spoke.
"This feeling" Gray spoke standing up "She's a Demon" he glared.
"Actually the appropriate term is Etherious" Natsu told him.
"Why did you bring her in here?" Makarov asked.
"Well I overheard a certain topic between two sources that she was causing trouble to put it mildly" Natsu explained "But when I went there it turns out it wasn't the case, it was the other Demon causing that death and missing people" he told them "the other one tried to kill her and steal her power" he said.
"needless to say I may have saved her and befriended her" Natsu explained.
"Is this true miss?" Makarov asked.
Yes I know I should've stopped Kyoka but never had the spine to do so, but when she turned on me I know she wasn't who I thought she was and I know it's alot to ask but can I join the Guild, Salamander-Kun is in?" Seilah spoke.
"Oh right where are my manners, my friends call me Natsu, Natsu Dragneel" Natsu told her.
Gray walked up to them with a scowl "I don't trust you but I trust Natsu" he spoke to the Etherious "So if he said there is something worth saving then I'll trust his word, but you will have earn our trust" he said firmly.
"That is what he told me" Seilah noted.
"Well with that decided Welcome to Fairy Tail I'm Makarov" Makarov said.
Time skip
A few months later Seilah had proved time and time again she can be trusted and can be a good friend, so Gray decided to Trust her and give her a chance.
"Well Seilah you have earned your right to be here with our Guild" Makarov said "I hate to give away a woman with huge knockers like those" he whispered.
But Natsu heard him and bopped him on the head "Be serious will ya'h" he muttered.
"Welcome Seilah!" the Guild cheered making her smile
Mira and Erza walked up shook her hand and introduced
"Oh and Natsu was it?" Seilah spoke.
"Aye" Natsu replied.
"Thank you" Seilah smiled wrapped her arms around him and hugged him tightly lifting him off the ground making Natsu grunt this woman was strong as she hugged him like a human teddy bear, she had quite a grip her breasts pressed into his his chest.
"Your welcome" Natsu grunted out and patted her shoulder, then decided to thank him in Demon and pecked him loudly on the cheek with a smooch sound making Erza and Mira eyes twitch "Thats how we say thank you in Etherious" she smirked putting him down.
"Natsu always lucks out" Gray smirked as Natsu was right again a Demon can be Good just like regular humans.
