I do not own Katekyo Hitman Reborn and High School DxD. I only own this story.
How dare he?! How dare he think of using her dear sister?! She was the most important person in an entire life. She won't let anyone take advantage of her dear sister. She will make him pay for that.
Kuroka angrily though this as went to her 'King's' place. She was ready to prepare to kill to protect her dear little sister. That bastard was planning to use little Shirone for an experiment. It didn't matter that that man had taken them off of the streets and gave them food, clothing, a place to call home. The sick devil was going to regret his decision.
She made sure not to be notice by anyone as she went to do the worst thing she would ever do in her entire life. She may regret this decision later but she couldn't let her sister be hurt by her ignorance and her indecision. Shirone was the only family she had left.
As she came close, she heard some laughter from her dear king, he laughed as a mad man for some reason. She heard him say: "You were one of the greatest skies to be, and yet here you lie; betrayed. How do you feel about... second chances?"
Hearing laughter, Kuroka then saw an array of lights dancing from around the corner she was hiding behind. The very objects that littered the room began to rise while power filled the air. Temperature was rising, even causing Kuroka to sweat within seconds.
"Now rise, and serve me." Her King commanded, making wild gesture to the corpse. "RISE! AND! SERVE!"
There was a grunt. Then a growl. "I... serve... NO ONE!"
The voice seemed so powerful and emitted even greater heat. Kuroka was beginning to sweat bullets. She peeked around the corner she had her back to to see who was the individual with curiosity. But the only thing that filled her sight were flames that covered a young man, that seemed almost the same age as her sister, maybe little bit older... or even younger? She couldn't tell because of his not very tall height. The flames were orange but also held a dark color, almost black. Those black flames emitted a lot of magic. Kuroka shivered by its intensity as she didn't realize that she had stepped out from her hiding spot to get a better view.
"What do you mean you serve no one?" Their king asked outrage. "I have summoned and revived you giving you another chance! YOU WILL SERVE AND OBEY ME!" He screamed at him as he prepared to use demonic magic on his new subject.
He sent his spell towards the individual whose flames seemed to be more intensive and more dangerous as it began to cover his all body. The spell was dissolved by the flame that moved defensively to protect the boy. It was as if they were alive.
The king was perplexed in front of his spell not working. This person was supposed to be his masterpiece, his puppet, his queen piece that would destroy any enemies in this path. "NO! NO!" The king yelled in frustration and rage but it turned into a slight bit of fear as he noticed that the brunette had been walking towards him. "YOU MUST OBEY!"
The boy grabbed the one who resurrected him by the throat. He glared directly towards the Devil's eyes with a cold expression. It was almost so... neutral without a single shred of remorse. He heard the choking but didn't loosen his grip. "The dead only wish to rest." He stated as he threw his victim against the wall.
The body that was tossed against the flat surface fell onto a desk that was filled with all sorts of papers. The sheets scattered around the area as the Devil groaned while glaring. He then noticed Kuroka out of his eye. "You! What are you standing there for?! Kill him!"
Kuroka could only watch as the boy craned his head slowly over towards her direction. Walking around to avoid being in his line of sight, the youkai saw that her 'King' was getting back up already, preparing some sort of flame spell by the look of things. But that was when she remembered her objective. Rushing forward, she dashed right past the boy and punched her King right in the stomach. With the power of Senjutsu and Youjutsu, it was a devastating blow meant to kill.
The Devil doubled over in pain, falling to his knees. Coughing, he spat out blood violently while grinding his teeth. "You bitch! You betray me too?!" He exclaimed as the spell he had been preparing against the boy was about to be thrown towards her.
A single foot came from above however and aimed the spell right towards the floor.
Kuroka was blown away from the blast, but the 'King' was not as lucky. The strength in that spell combined with how close he was provided to be too much for the body to handle as the Devil was nothing more than a corpse within the room. Only the person who had been resurrected recently was standing right in the place where Kuroka and the corpse were a few seconds ago. There was no glee or anger in his features, just a downcast look.
Kuroka was awestruck by what the man did, but quickly understood that they needed to escape before people caught him. She owed him at least that, he just saved her precious little sister… That's right, she had to still-
Voices were soon heard. There were coming and there was many. "I don't know about you, but I'm getting out of here, nya." She commented as she began to run towards another end of the room. She was about to open the door when she realized that the person still didn't move. Turning her head around, the male was just standing in place like a statue. Sighing to herself, she ran back and grabbed the boy by the arm and began to drag him along.
"Come on! You don't want to get caught by these devils. Trust me, nya!
(Time Skip)
A newly reincarnated devil just beat the crap out of a fallen angel that had passed as his girlfriend and killed him after just because he seemed like a threat to her kind as well as faction. She then tried to use another innocent girl that had been exiled from the church to take her sacred gear to make herself powerful, sacrificing the outcasted maiden. But she was quickly stopped by that devil who awakened and was strengthened his sacred gear.
The master of the boy came back with some dark feather to show that fallen angels that her allies were destroyed by her. As she moved her red hair from her face, she prepared a spell to kill that fallen angel. The young Devil who had just been resurrected didn't even raise a single finger, but an unreadable expression was worn on his face as he looked up through a window of the church they were in.
After destroying the fallen angel, the crimson haired devil gave the sacred gear she had stolen from the little blond nun. Not just because of that, it didn't mean the blonde girl would stay alive as the gear was a part of her that was stripped away before. She then reincarnated the nun as her bishop. The young devil was happy to see that his friend was once again alive, crying tears of joy.
A young man was observing their movement from one of the broken windows, somehow not being noticed as the events unfolded. He was wearing the same clothes as almost every devil that fought that night in this church, which was some sort of school uniform for the male gender. After seeing the girl being reincarnated, he left towards his house. It's good thing that he didn't have a shift for his part-time job.
Steadily, he walked down the streets. His speed was slow. The sluggish pace even caused him to lag behind the passing group that was just at the church despite his head start. Even so, he kept an eye on them for a few more seconds before turning on the sidewalk. He finally arrived at his home. Opening his door, he went directly to his bedroom.
He opened the door of his resting chambers to find older woman who had a two tails and cat ears on his bed reading a book. She was almost naked as her black kimono seemed to be almost undone. She barely looked at him as he entered the room, kicking her legs around in a playful manner. The brown-haired individual sighed at her presence.
"Do I have to make food for you once again?" He asked as he quirked an eyebrow in her presence while staring at her. It was obvious in his voice that the girl's presence was a bit annoying.
"Can't you be a little nicer to me, Tuna-kun?" She said pouting at his sentence. Kuroka rolled onto "I thought we were accomplices, nya?"
"I am already returning your favor by watching over your sister." He deadpanned as he sat down in the chair next to his desk. "Anyways, are you going to talk her or just continue to let her hate you for absolutely no reason?" He then asked, folding his arms and staring, expecting his answer.
"You know why." Kuroka stated, looking away. "By the way, you really changed Tuna-kun. Especially with your hair. I would have never thought before you could tame such spiky hair." She said smirking. It was true though. Tsuna's hair still had a bit of a spike to it, but it had been flattened slightly and there was a bit of a slim mane growing down from the head to the bottom of his neck. "But it kind of makes you more handsome, you must really have a lot of fangirls at that school, nya."
"I don't care about that. It's annoying, but it is apparently useful to get a better salary at my job." Tsuna scowled slightly as he brushed a hand through his now straight hair. "When I looked at my hair back then, it only made me remember of that past. Now I don't have to remembered their betrayal every time I look in the mirror." He said as his eyes flashed an orange while burning a dark black.
"It's weird that the devils in the school didn't notice your presence. You must really be good as hiding your presence especially because of your popularity, nya." Kuroka said smirking as she looked at him when saying the word 'popularity'.
"That's the teachings of the world's greatest hitman at work." Tsuna said in a matter-of-fact tone. "Besides, my popularity is only due to my grades and nothing else. I have no interest in making friends that would eventually... betray me." He said with a sigh and a tone that mixed anger and sadness together in his voice making Kuroka frown at what he said. She kind of wanted him to go to this school to open himself more but even after all of this time, he didn't open up one bit. "Do you have any other purpose to come to my bedroom other than taking my food?"
"I might want to pass an enjoyable night with you, nya." Kuroka said winking, showing more of her body while stretching her back in a rather seductive way. Tsuna didn't spare a glance as he began his homework. It took time, but Tsuna eventually was unaffected by these sorts of actions Kuroka would constantly do. Teasing him was apparently one of her hobbies. It was almost some sort of competition between them to see if she could Tsuna to at least fluster a bit.
The Nekomata nearly succeeded every time she would end up playing with herself right in front of him.
The first time that happened, Tsuna learned that she didn't wear underwear at all.
Kuroka sighed knowing how the boy was. He wasn't really fun to play with right now but she promised herself to help him heal at least a little bit.
She knew his past and the reason he was like that. He saved her and her sister, she at least owned him that. Tsuna was a broken young man who didn't want to serve or boss anyone. He was lonely but he would never let anyone approach him. She knew that in school, people called him the lonely knight who had perfect grade. Well, she knew that it made girls wanted him more as he got few letters of confession each week, which he refused sometimes brutally, sometimes a little more gently, which only made the girls wanting him more. That kind of annoyed him to no end. Scratch that, it did annoy him to no end.
"So what do you want this night?" Tsuna asked with a sigh her common guest as he knew she liked how he gave her his food. There was no point in chasing her out. He just didn't want to deal with the headache that came when forcing her to go away.
"It doesn't really matter as long as it is fish." Kuroka said as she was snapped out from her thought as she imagined the delicious food she was going to eat. "By the way I didn't know that you owned that kind of book, nya." as she turned her attention to the book she was reading and found under his bed. It was some sort of graphic novel of very... 'adult' things.
"I borrowed this book from the stupid perverted trio to make sure that the girls would leave me alone, which didn't really work. It only made some of them more aggressive." Tsuna groaned he closed the book he as working and stood up to go to cook the food. "Seriously, what kind of hormones are these girls filled with?! Back in my day-" He cut himself off, realizing what he just said.
"...You totally sounded like an old man there, nya~." Kuroka sang, giggling a little bit.
"Shut up." The brunette grumbled.
Tsuna went to the kitchen to make the food for the two of them. They then ate the food together in silence. Then they went to bed. Kuroka slept into the same bed as him after they both took a shower to clean themselves where Kuroka cleaned his back who did the same thing for her. He didn't really mind it all, but he just at least wondered if these were really ways for the female to turn him on.
The next day, Tsuna awakened his self at his usual time as he prepared his lunch and made some more food for once Kuroka woke up. He left his house, not his home. it would never be his home without that person's sweet voice always greeting him. He murmured "Ittekimasu."
Tsuna walked up to his school, not taking notice of the girls around him fanning over his presence, and the boys glaring at him. He couldn't care less about people's opinion about him. They could believe whatever they wanted. He didn't just care. He wanted to be alone.
Tsuna looked around him to see the famous perverted trio as two of the idiots seemed to scold their friend who had become a devil a few days ago. The brunette mainly took note of the new devil since that boy had joined up with that Occult Research Club where Shirone was.
He had a normal day as his classes went with any events as the teacher gave him his tests back who all had 100 on them. He was known as one of the best students of their year. The only person who had a rivaled him grade-wise was Rias Gremory. He had to admit, that girl was a really gifted person as well as a great king and person towards the members of her peerage. She was also great with her magic as it was sometimes hard for him to spy on her without them realizing it due to his own flames sometimes reacting to it on instinct.
Tsuna didn't really cared about her greatness, she was for him a person that needed to use the power of her peerage for her own freedom. He could tell that she would need it in the near future as he could see that he wasn't the only one spying on them. There was a strange looking bird that was perched on the window of their ORC room. Narrowing his eyes towards the creature, the odd creature looked like a baby phoenix. Tsuna was half tempted to snatch the bird and crush it but didn't want to risk letting his presence become known. Taking a guess, that bird would have belonged to the Phenex family. Their son, Riser Phenex, was actually to be Rias Gremory's fiancé if Kuroka gave such information correctly.
He wondered if that Riser person was going to be a trouble or not. Seeing the potential of Rias' pawn, they should be able to win a fight and disengage Rias' engagement. He shouldn't need to do anything. He wondered why he felt the need to interfere. He only agreed to watch over and do nothing else.
He promised himself to never become attach to another being to make sure he was never betrayed like his old precious friends did to him. While he trusted them, and was ready to give his life for them, they gave up and surrender his life to his enemies without any doubts. He crushed the soda can that he was holding as he remembered their betrayal.
