'Demon thoughts'
"*Eagle high pitched whistling*"
Natsu eyes open lazily as the sound of a eagle high pitched whistling fades away, he yawns and notices that he's leaning on the wall of the entry of the cave. 'Oh yeah I fell asleep here, and oh that right I have the view of the ruins of the Bureau of Magical Development.' Thought Natsu looking at the burned remains of the building he destroyed yesterday. He feels like hell yesterday fight really took a lot out of him, he takes a deep breath to adjust to the pain as he adjusts he hears soft breathing noises he turns and sees Sayla sleeping next to him sleeping soundly with her head resting on his shoulders. Natsu is so tired that he didn't even noticed her sleeping next to him, he stares at the demon girl for a second.
'Erza and Kagura do the same exactly thing this girl is doing...' Thought Natsu but his thoughts were interrupted by a sharp pain in his chest he quickly stands up causing Sayla to wake up. She sees Natsu grabbing his chest tightly and sees him starts to throw up blood, she runs to him.
"H-hey are you ok? You need to sit down" Sayla says as she helps Natsu sit down, the pinkette is in too much pain to hear what she said, but let's her guide him back to the ground.
"D-damn it, m-my body hasn't recovered fully yet. S-Sayla do you have any dark, chaos or fire magic?" The dragon slayer asked Sayla. She looked at him completely stunned, why would he asked her something like that while he's vomiting blood and twitching uncontrollably, but she decides to answer the question.
"Yes I do I-I use dark magic." she answers the question nodded her head.
" I n-need you to hit me with any dark magic you have." Said Natsu trying to control his body but having little success in doing so.
"W-what th-that crazy you want me to kill you?" She protested.
"I don't care just hit me with all you have." Sayla hesitates but decides to trust Natsu so the black haired demon girl stands up in front of Natsu and takes a deep breath, her eyes start to turn completely dark as if someone pulled her eye balls from her socket leaving only the hollow space inside the sockets. She sticks out her arms and aims them at Natsu, her body started to be engulfed in a dark aura similar to Natsu when he turns on his dark magic but unlike Natsu's hers seems innocent and somewhat calming. The pink haired demon notes that while still trying to control his body movements. Sayla raises her hands and aims them back at Natsu shouting.
"Dark Library!"
Natsu is bombarded with dark magic shaped books, hundreds of them all aimed at Natsu. Sayla throws as much as she could at the pink haired demon. She notices that the her attacks are disappearing as soon it hits the pinkette, she launches the last of her dark magic attack to the pink haired demon and stumbles to the ground exhausted. Natsu helps himself up while wiping his mouth. "That was tasty and not to mention that felt good." The demon said with a smile on his face and standing up normally, he walks to Sayla who is on the floor resting from the magic she throw at Natsu. "Thanks for the magic. My body is metabolizing the darkness helps to heal my wounds. My body isn't bothering me as much any more and I'm more focus thanks." The pink haired demon says looking down at the black haired demon, Sayla gives him a smile in response. Natsu turns around to look at the outside of the cave and out of nowhere he snatches Sayla from the ground with his demonic tail.
"N-Natsu what are y-you doing?" Asked a scared Sayla who is being warped around by Natsu's tail.
"We are leaving what do you mean, I need you to answer some questions and I don't want them answered here. Besides I'm hungry and I take it you are also." Responds the pinkette by jumping from the cave to the ground, all the while Sayla screams from the fear of jumping from high mountain side to the ground with no support other than Natsu and his tail. Natsu lands safely thanks to his magic, and places Sayla on the ground. The pinkette starts to walk north signaling Sayla to follow him, the black haired demon girl follows him.
"Say Sayla have you ever want to conquer the earth?"
•Two days later.•
On top of a hill looking over Magnolia stands Natsu and Sayla who is now in her human form and donning a light-colored bandanna with lined design and a crescent moon-shaped hair ornament on the back of her head. She also wears a zebra-patterned cloak with a crescent moon design on the back. With a black and white scale pattern kimono and on top of that a gray colored scarf. She has a wooden staff strap on her back that complements her new outfit. The staff has a black and white twirl formation covering head to toe of the weapon. At the tip of the staff sits a skull that is painted black on left it's and white on its right. In short the staff is modeled similar to the yin yang symbol. Its called the staff of balance the Inbetweener.
"That's Magnolia and the tallest building is the guild hall of Fairy tail, the guild you are going to join but now you will meet Erza and Kagura." Says Natsu looking at the view of Magnolia. Sayla turns to him and nods.
"Yes Natsu-sama anything you wish." The black haired girl says smiling warmly at Natsu. The pinkette glances at her for a second and returns back at the view of the town.
"I still don't understand why you feel more comfortable in that form." The Etherious says which makes Sayla a bit nervous.
"W-well Natsu-sama this is my original form, I am human after all. And you did tell me that my demonic form was draining a lot of my magic energy away." Answered Sayla back to Natsu trying not anger him.
"I know that. But it seems that you enjoy this your original form more than your demonic form. My human form bothers the shit out of me, this form is more comfortable." The pink haired demon says looking at his scaled covered hand with pride.
"Eh Whatever if you feel comfortable in that form go on ahead. Aw there they are just in time Erza and Kagura two of my favorite people." Natsu says glad to see his sword wielding students. Both Erza and Kagura bow their heads to greet Natsu.
"Welcome back Natsu-sama how was your trip?" Asked Erza.
"It was fine, Sayla this is Erza and Kagura. They are my students I told you about, you will train besides them for now on. Girls these is Sayla Lunasea she is a demon takeover wizard." Natsu introduces Sayla to Erza and Kagura. The black haired girl bows her head.
"H-Hello Erza and Kagura it's a pleasure to meet you, I hope we can get along." Sayla says nervously extended her hand out to the sword wielders, she can feel the power coming from both girls. The power of Natsu's training at work, Sayla is glad she made the right decision to accept Natsu's tutelage.
"Hello Sayla I'm Erza Scarlet and this is my sister Kagura Mikazuchi, thank you I hope we can also get along." Erza introduces herself and Kagura, Kagura nods and gives Sayla a friendly smile.
"I want both of you girls to introduce Sayla to Makarov and convince him to let her join the guild, as soon as he gives Sayla her guild mark help her to get settle down. I give her money to get a room at your residence." Natsu tells both Erza and Kagura, they nod in agreement. Natsu suddenly fells a dark presence near him and his students, he turns to the woods.
'This magic energy is definitely not Zeref, this magic it's not just dark it's evil. Whoever it is obviously wants to get my attention, they would've attack by now.' Thought Natsu. The girls look at him wondering why is he looking at the woods for.
"You girls should start heading into town. I'll get in contact as soon as I can." Natsu said still looking at the woods, all three girls knew something was wrong as Natsu's facial expression changed from curious to one of caution. Erza decides to speak up to offer her aid.
"B-but Natsu-sama maybe we can he-"
"No get you girls need to leave. Now."
"But Natsu-sama we-"
"DONT MAKE ME REPEAT MYSELF." Natsu turned to Erza who completely froze at the sight of Natsu's eyes.
'Th-those eyes, w-why does my body feel so heavy?' Erza thinks as she tries to move her body but fails at this. She is simply terrified at Natsu's glare, Natsu's glare makes her feels like a ant facing a hurricane. It feels like she up against a army of millions, she tries to look away but can't the fear in her is to much.
"My apologies Natsu-sama, cmon Erza let's go. You too Sayla let's go into town we can go and get something to eat." Kagura says dragging Erza by the arm who is still frozen in fear from Natsu's death glare. Sayla helps Kagura drag Erza to town as fast as she could. Both girls turned back to see Natsu and see what has Erza all shaken up, they see demonic eyes piercing through them like getting impaled by 1000 swords at the same time. They turn away quickly not wanting to have those look at them for another second longer.
As soon as the three girls are out of sight the pinkette turns back to the woods, where the evil magic energy was coming from. "Come out now, whoever you are." Natsu says in a serious tone.
"Muhehehe interesting students eh? I here I thought you were a loner. Allow me to show myself." A figure appears floating above the trees of the woods. A tall elderly man with long, slicked back, silvery white hair, revealing his forehead. He also has a mustache, and a similarly long yet mildly thin and curly beard, reaching down to his lower chest. He has some wrinkles on his face, as evident of his extremely advanced age; nonetheless, despite this age, his figure is muscular and well defined. His right eye is covered by a eyepatch, but right away Natsu can tell that he's not missing a eye because most of the magic energy from this old man is coming from his right eye socket. This old man attire consists of a dark shirt paired with armored shoulder pads and shiny gauntlets, as well as chain-mail covering the parts of his arms remaining exposed, simple light pants with flames near the edges - held up by what looks like a light belt composed of two straps with the relative buttons, possibly part of the pants themselves, and dark, simple shoes/boots. He wears a helmet matching his armor, the helmet similar to that of Greek warriors. Over this outfit he wears a large, dark cape, bearing a symbol on the back that Natsu recognizes as from the dark Grimoire Heart.
"I am Hades the guild master of the strongest dark guild in all of earthland Grimoire Heart. It's a pleasure to meet you Onslaught of the fairies.
