Happy New Year! The last time I update was New Year's Eve so I thought I need to update this once in 2017 now. Anyway, I am glad some of you guys are liking this story. I do need you guys to review if you want this story to continue.

With Natsu

Natsu woke up rubbing his head 'what happened?' Natsu thought then the memory came back to him he saved the captain of squad 13 and then him pasting out. He looked around his new surrounding he was in a cage, with large steel bars and some kind of … magic barrier to reinforce the prison. Natsu was Not happy he had told them that he was not going to be treated like an animal and he had told them that he would help them; so why? Was it because what Rukia heard last night or at least he thought it was last night.

"Oh, good you're up." Natsu looked in the direction of the voice and he mentally ground "the head captain told me I was not to start any experiments until you woke up."

"Is that so I feel the pain more or something." Natsu asked getting up from the stone floor and noticing a metal chain on his ankle. "Really; I told you I do not take kindly to being treated like an animal." Natsu said starting to get a little angry

"Relax; we are not going to hurt you … let." Came a new voice and this time it was Sui Feng the captain of squad 2, Natsu rolled his eye sat the over confident captain.

"Tell me… how is Ukitake doing?" Natsu said suppressing his growing anger.

"And why would a demon like you care?" the captain of squad 2 asked

"Look I am not what you think. I just wanted to know if he was alright that's all." Natsu said he really did not like this captain and she was starting to get on his nerves.

"Well… Captain Kurotsuchi I think we got everything we need you may start on your… experiments" she said not answering Natsu's question and then began to walk away when she heard Natsu shout after her.

"I wouldn't do that if I were you! Trust me you won't like what will happen!" Natsu yelled only for Sui Feng to smile because she has heard threats like that before and they turned out to be nothing so she thought the same for the pink-haired freak she was not scared and had no worries of him getting out. Oh, how wrong she was.

With squad 13

"Are you sure you are feeling alright? Maybe you should rest some more." Said one squad member

"I feel fine, better in fact. Now please let me go see Natsu." The Captain said trying to push thought

"Captain that guy is one of the demons you shouldn't-"

"Shouldn't what? That boy saved my life and I should return the favor and save his." The captain tried again. Word had gotten out all over the Seireitei now everyone knows what Natsu did and also what he truly was. Some were finding it hard to believe others were glad that Natsu was now locked up. But captain Ukitake did not feel right leaving Natsu to die when he had saved his life.

Before anyone anything else could happen, there was a huge explosion by the squad 12 barracks alarms started going off soul reapers were running in the direction of the expulsion and squad 13 was also running to the scene.

Squad 12th barracks were in chaos soul reapers running from the scene smoke and fire prevented anyone to see what everyone was running from.

"M-monster!" one said as he ran pass the squad 10's captain. He looked on wondering what could have done this. And as the smoke was starting to clear that is when they saw it…

Natsu no END. The creature looked scarier than the first time they saw that form; large red and black wings were out stretched, black flame tattoos covered his arms and part of his chest, his eyes were glowing red and held no mercy as he held the captain of squad 12 by the neck sharpen claws dug deep into his skin. Even the air around him seem to grow darker much darker and as the sky turned a reddish color as well. It seemed like you were staring into the depth of hell itself with no hope of seeing the light of day again.

"Natsu! Release him immediately!" Toshiro yelled but Natsu slowly turned and locked eyes with the captain, Toshiro could feel the power radiating off of him and he froze those eyes seemed to trap the captain in place with the feeling of imminent death.

"No" Natsu asked in a deep demonic voice that sent a chill down everyone's spins.

"You don't want to do this!" Ukitake yelled but Natsu ignored him and squeezed harder, making the captain squirm in pain.

"Take this!" captain Kenpachi yelled as he charges Natsu up Natsu just grabbed the sword and swung it around sending the captain of squad 11 into the already destroyed building.

"Natsu! Tell us why you are doing this!" Ukitake asked trying to buy time for some other captain to show up as well as to make sure everyone got out of the building safely.

"You let this worm experiment on me, trapped me, and treat me like an animal" Natsu said anger filled his voice. "I warned you this would happen." He said as he turned to face the captain of squad two that had just arrived; captain Ukitake and captain Hitsugaya looked over to the new arrival and saw her eyes widened at the demons statement.

"Captain Suì-Fēng, did you know this was going to happen?" Ukitake asked.

"… he was just making threats… I didn't think-" she started but dropped off as her face hardened and she charged Natsu who blocked the attack with the body he held in his hands. She jumped back as Kenpachi came back eyepatch off and a smile on his face. Natsu throw the unconscious captain to avoid his arm being cut off by the crazy captain, he dodged attacks from Sui Feng and Toshiro as well. More captains and other soul reapers started to appear all ready for a fight but Natsu's anger only grew and as his anger grew so did his power.

Lightning and fire exploded in every direction nobody could really lay a hand on the ferrous demon. Ukitake stood his eyes widened at the power he was witnessing and to be honest it terrified him, the only people that didn't seem effected by this level of terror was the members of squad 11 they seemed to be having fun trying to defeat this demon that did not want to go down. But as Natsu's rage grow it seemed that his attacks were becoming more dangerous and more out of control also his demon fetchers seemed to change and if it was possible more terrifying this was the definition of a monster.

When things couldn't get any worse another explosion was heard on the other side of the Seireitei Natsu seemed to freeze and look in that direction. Kenpachi thought this was a good time to attack but before he could land a hit Natsu disappeared in a red blur.

On the other is of the Seireitei

Another demon had shown up and was ranking the place since all the high-ranking soul reaper were fighting Natsu there was no one that stood a chance against this demon and they were quickly over run. But that all changed when Natsu suddenly appeared knocking the surprised demon back a little bit. Regaining its composer, the demon attacked Natsu but he blocked with ease. It was easy to say the demon did not stand a chance against a very angry Natsu.

At the end of the fight the demon was nothing more than a pill of ash and the surrounding area destroyed luckily is wasn't completely rebuild from the last attack, but still the area was black with scorched earth and ash.

"Natsu have you calmed down?" Ukitake asked as he and some of the other captain came to the new clearing. The demonized Natsu just stood there looking at the pill of demon ash as his demon fetchers disappeared.

"Please... don't make me do that again." Natsu said in a low voice up loud enough for them to hear. He did not to get angry like that again.

"Do you know the gravity of want you have done?" the head captain asked coming up to the edge of the crater; he was not in the fight but had seen what had occurred. Natsu back was still turned away from the group of soul reapers, and he stayed silent.

"Answer!"

"Are you scared of me?" Natsu asked his voice still low. "You are arnt you…" he finished before anyone could give him an awnser

"I am sorry for the damage I caused… I do not like being caged." Natsu said he turned around to face the soul reapers they were haft expecting the cool red eyes but now they were just a black void.

"Why did you not tell us sooner that your were a demon?" Ukitake asked careful what to say so he does not anger the teen further.

"I didn't know how you were going to react… and if I didn't have to save your life I would have kept it a secret." Natsu said is voice full of regret. "I am not like the other demons… I was once human." Everyone was shocked at what they heard; sure, hollows were once human and some of them thought so were demons but after hearing Natsu it turns out that most demons weren't originally human.

"You need to explain everything you have been hiding… or we can fight so more." Natsu flinched a little at thinking he would have to fight the entire Seireitei and loosening all sense of humanity like he almost did a moment ago, if it wasn't for getting his anger out on the demon he might have killed everyone in the soul society before he regained control… if he regained control.

"I will tell you everything on two conditions." Natsu said his face devoid of any emotion. "one no more trying to loo me up anywhere or trying to experiment on me. Two you help me to get home." Natsu said glaring at the head captain daring him to challenge him. After a moment, the head captain nodded.

"In one hour, I want a mandatory captains meeting with lieutenants and Ichigo's team." He said as he walked back to his office. Everyone stood there shocked at what just happened; Natsu had just gone on a rampage and the head captain isn't demanding an execution. Seeing all these face Natsu sighed getting some people's attention.

"I am not sorry for almost killing that captain of yours so if you are wise I would not let the Science guy near me or I might just rip his head off." Natsu said as he walked back to his room at squad 13 barracks. Everyone again just stood there not knowing what to think of the current situation.

One hour later

"Speak." The head captain spook in a demanding tone signaling the beginning of the meeting.

Natsu sighed "A long time ago I was kill by an attack on my village… I was four years old. My older brother could not handle my death so he searched for a way to bring me back to life; in doing this he cursed himself where he could not die and the more he loved life the more he took it any." Natsu passed letting that sink in.

"As years passed my brother begin his mission on dyeing he created demons also known as etherious to kill him but none of them could they were not strong enough so he infused the power of etherious into my body making me a demon."

"So, your brother made the demons that are attacking us?" Shunsui asked.

"No, these demons aren't my brothers!"

"Then who made these ones?" Shinji asked Natsu looked down.

"I don't know. These on are different… they have curses I have never seen before which is saying something because I created curse power." Natsu said in a low voice

"Please contiue the story." Lisa Yadōmaru asked really into the story, she wanted to know more about this demon. Natsu sighed again

"The rest of the story is not really relivent." He said and she looked a little disapointed.

"What else can you tell us about these demons." Kisuke Urahara asked more intrested in these new man made creations.

" Well each etherious has a different cures power; of coures for my brothers demons they were all created by a book." Natsu said but when he was met with confused looks he desicded to explian. "Zeref my brother wrote these book called the books of zeref they held evey dark magic of sorts… he would write the power to create and destory the demon in these books." Natsu said hesitaing a little but brought out the book he retrved in the world of the living.

"Are you saying that you had one of these demons with you and you didn't say asnything." Sui feng said

"I am not your subordinate what I keep hiden is my business." Natsu growled.

"So how does it work?" Kisuke asked starting to get exsided. Natsu sruged and put the book in the senter of the room steping back he said a few words under his breth and the book glowed a dark purple-ish black color then the book seemed to morph and formed a hominod figure; it was a femal demon half-human/half-aviary characteristics. She seems to be of average height her face was mostly covered and she wore a plrupleand green clothing.

"This is Kyôka." Natsu said as the demon opened her eyes, all the soul reapers in the room tenced up ready if she was going to attack but when she saw Natsu she immeditaly fell to the floor.

"Lord END how may I be of service?" she said head bowed low. Natsu sighed not really like being called END.

"Stand up." Natsu order which she immeditaly obayed and she took this time to servay the room. She did not trust the prople in this room and think the might be hostail her arms transformed into deadly metal talons.

"Stand down Kyoka they are not our enemys." Natsu said and a little reluctenly she backed down and walked over to Natsu's side.

"So how many demons do you have?" Sui feng asked eyeing the female demon up and down determinimg her threat level.

"Right now just her for some reason I found her book in the would of the living after the last demon attack." He siad

There was a moment of scilent while everyone was thinking this over.

"Is she trust worthy?" Toshrio asked only for the female demon to anwser.

"I am only loyal to lord END!" she growled only for Natsu to but a arm out blocking her path to the squad 10 captain making her back down.

"Well… Natsu what else can you tell us?" the head captain spock bring the group back on topic.

"Not much that is pretty much all I know on the cerent topic. But I can tell you if we find who is controling these demons we can put an end to this." He said thinking about how to find siad person. The head captain just nodded.

"If there is nothing else anyone would like to add this meeting is over." He said and when no one spook up he closed his eyes and everyone left the room all kepping an eye on the new demon.
