I do not own Katekyo Hitman Reborn and High School DxD. I only own this story.
If Tsuna could be honest, he was getting rather bored of watching the peerage that Shirone/Koneko resided in. Mainly because of that pervert and all his actions being the constant performance his eyes had to witness for a while. Who could believe he would go with his friends into the girls' locker room, as they locked themselves into a locker to watch the girls changing. That sort of action never worked in fantasy, and it will never work in reality.
It was actually a bit risk to keep his eye on the members of Gremory's peerage, especially since it was Koneko who had a hearing and a smell heavily sense experienced and intense. Tsuna kind of smiled when he saw that Koneko noticed quickly that they were spying on them and unrevealed them to the girls who had their time punishing them. It was certainly amusing to see the smaller girl practically rip off the locker doors.
Tsuna noticed the emotion that took over him, quickly turning those upward lips into a neutral gaze. He distanced himself from them even more seeing that that idiocy was contagious. He didn't want to become the same as that idiot devil. He still watched the tennis match between the both high-up peerages in the school. He sighed at the rather stupidity and perversion of the students of this school. He couldn't even believe that at his time as a normal teenager, his classmates were way different. They were ignorant, bullies, and eccentric people but he couldn't believe they were this way.
Tsuna then began to spectate a dodgeball match between both peerages because the tennis match had ended up in a draw as they used magic and destroyed their own tennis rackets. It still turned out as a war as it seemed that Gremory and Sitri still decided to use magic once again. He sighed to himself at how this was possibly one of the more pointless moments of his life. Maybe he should just stay at home and spy them using that 'flame'. At least he could do his homework while spying on them.
Tsuna walked back to his house, thankful for the fact that next week or so Kuroka wouldn't be at his house. He would have finally sometime alone. He didn't mind her presence much, but she could be sometimes trouble. She wasn't really a problem when he slept as he sometimes missed the warm of another person, plus he didn't mind her purring in her sleep, not that he would ever admit that. Despite his rather dark, cold attitude, that didn't mean he was emo and hated everything.
He watched the Occult Research Club as they went to get a familiar for Asia or Issei, as it seemed you can only get a familiar once every full moon, or something like that not that he really cared. He just knew that Koneko got a small cute kitten. Tsuna wanted to hit his head against his desk as he saw the scene with the smile. The brunette couldn't believe the idiot that he was. That sadistic training from Reborn was probably affecting him a lot more than he expected. Well, to feel good one must pay a horrible price.
Everything was getting in some sort of disturbing rust events until someone stronger than any person he ever met in the school came into the Occult Research clubroom. The one Kuroka characterized as the strongest queen, Grayfia Lucifuge. Tsuna found himself slightly shivering at her presence as he observed her arrival, despite him not even being in the same room. Frankly it wasn't really her presence that sent the small chill down his spine, it was the way that she looked towards where he was observing them with that 'flame'.
He wondered if she truly noticed him, this fact would make her very dangerous. Tsuna decided to stop observing them as he could guess what was going to happen and he didn't want her to trace him down if she, by chance, noticed him.
That's when the small headache came in. Those 'flames' really did have their great uses. The only problem was that when it actually came down to using them as actual holes in reality. Being able to form one opening near yourself is completely fine. However, the coordination's of the place where your next opening would end up to be was more difficult. More so since that one rip was right out of his line of sight with a constant source powering it.
He decided to go to his part-time job as a butler for the sort of Host Club. His popularity always helped the café as it always made the café full with his fans, be it female with a surprising amount of males. The other butlers were nice enough to help him in the time in need but never tried to befriend him more than he needed to. It may also be because they were all a few years older than him. Or that he sometimes slipped away from their attempts.
Tsuna came back after being forced be at least a little nicer to his customers who were sometimes crazy fans. It was not his fault that they constantly dodged his questions related to orders. Not only that, it also turned into a full blown one sided conversation. To Tsuna, he couldn't decide if it was he who was talking to a brick wall or if he were such a solid surface who responded back incorrectly.
He prepared some food for himself as soon as he went into the kitchen. Weirdly enough, he prepared some fish as he was used to Kuroka's presence and unconsciously made too much food for himself. Perhaps he was a little too used to that female constantly visiting him from time to time now. He didn't really know what to do with the food. Maybe he should keep it for tomorrow but he couldn't use it as a bento since he didn't have school tomorrow. Well, there is also the term called leftovers.
A magic circle similar to the one Gremory's uses suddenly appeared in front of him in his kitchen. The previous person he saw at the ORC who made him retire from spying was right from him. A person who could possibly kill him in mere seconds if she got serious was just a few feet away from him. Well, frankly he didn't know how strong he was or if he could even stand a chance against her. But he knew that she could make his wish to make him return to where he belonged come true. His wish was to return to the dirt.
It's not that he would willingly throw himself into death though.
Back to the matter at hand though, if she began to attack, he at least had to make sure he was prepared for something. However, she bowed in front of him as she arrived. Not knowing what to do he bowed back at her. She spoke her first words to him: "It is nice to meet you, Tsunayoshi Sayake."
"It is nice to meet you too, Grayfia Lucifuge." He replied back in politeness. "Are you hungry? It looks like I have made too much food for myself." He said to her as he remembered what the most important person used to say to him. But still, to make sure he kept his hands behind his back as they were coated in the orange flames he was used to with a coat of darkness.
"Thank you very much, but I am on duty. I cannot eat during work. It would go against my duty as a maid." Grayfia told him with a emotionless face as she bowed back at him to apologize for not being able to eat despite his offer.
"I don't really want the food to go to waste, it is one of the lesson my mother taught me a really long time ago and since I probably won't live to see tomorrow. So please make sure it doesn't go to waste." Tsuna said not looking a bit frightened at the mentioned of his death, he only was sad when he mentioned his mother.
"Do not worry, Tsunayoshi Sayake. Or should I say the reincarnation of Tsunayoshi Sawada, Vongola Decimo, accomplice of Kuroka's escape. I only came to see why you were observing Rias-sama and her peerage. If you became a danger to them, I would need to take action to protect her." She said raising her demonic power dramatically to threatened him, but quickly she lowered it returning to her normal level which was still high. "But I think it isn't the case. My king doesn't think so also as we guessed that you are only here because Kuroka asked you to keep an eye on her sister as your identity isn't really known through the Devil's world, am I right?"
"You may be right, and what would happen if it was the case?" Tsuna asked nonchalantly not really caring about the conversation but still interested in her attention as she didn't want to kill him. She was kind of friendly which seemed to be weird as due to the Devil law, he was a rogue devil and should be kill before he becomes a menace to the devils and the humans and start attacking both of them to feed on their power. He already had several locations on his mind for escape as a patch of black was right under his foot just in case.
"Unlike Kuroka, whom existence and crime are quite known, your existence is notified to only a few who looked at that man's work and found what he was trying to do, so your crime hasn't been known so you aren't guilty of anything in the eyes of my king." She said without a lot of emotion as a first-class maid would.
"So let me rephrase my previous question, why did you came here for?" Tsuna asked with a sigh, wondering even more why she needed to point that he was found innocent. He finally dispelled his flames while scratching his head.
"My king just wanted to let you know that we know about you and that if you ever tried to hurt his sister, you will regret it." Grayfia said once again in intimidation. "And also that he would be thankful if you ever saved his dear sister and her peerage from a threat too big for them to handle."
Tsuna fought the need to face palm in front of the Maou statement, which was threatening and possibly thanking him at the same time. He questioned himself if Lucifer was right in his head, but he decided to not bring such subject that would probably cause an incessant list of the problem with that Maou. "Is that all?" He asked with a raised eyebrow.
"Yes, for now. My king can be... odd sometimes like that. He decided to keep your existence secret for now until you are deemed too dangerous to be left alone. Next time, my king will come himself." She said as she left in the same magic circle she appeared through, but right before she left, she turned to him and said "By the way, Rias-sama and her peerage went to train for their oncoming raking game against Riser-sama's peerage to decide what will happen with their wedding, so they won't be at school for quite some time. But everything should be fine so don't worry about Koneko-sama."
The devil couldn't resist the need to facepalm, and did it quite hard. Tsuna decided to go sleep as he didn't really know what to think in front of the scene that just happen. Tsuna trusted that woman's word as he decided to not investigate the Gremory's peerage. He may check on them one time this week. But he would definitely find a way to watch the fight to see the strength of that peerage.
(Time Skip)
Tsuna was quite surprised by the evolution of the young devil, he had increase his power enough to hurt the heir of the Phenex Family. The rogue Devil didn't give the young perverted devil enough credit and courage to pull what he did. To sacrifice an arm to hit the Phenex with a cross and gamble the fight with some holy water was impressive and quite clever for a pervert, especially after declaring in front of everyone that he claimed Gremory's virginity.
It seemed as he continued to observe the ORC, he quickly realized that the pervert idiot was assembling a harem. Since he saved Asia and Rias, he would say that it can be normal for them to fall in love with him, but he didn't expect the S queen to become interested in him. He didn't think that Akeno would also be a M as she was already a great S. She would be a hard person to deal with.
Tsuna was surprised by the presence of two holy power near the school on that day. He couldn't believe that such strong presence would come towards the school filled of two different devil's peerage. He went to see what was happening and saw two girls hiding their presence. He saw that the presences weren't from the two girls but from the presence from each of their weapons.
Tsuna decided to observe more those two newcomers, after a few days, he understood that one of them were linked to the perverted devil while the other disliked the reincarnation of the outcasted nun into a devil. He also understood that the Prince of the school also known as the knight of Gremory had something against holy swords because of trauma in his past with the church.
After continuing observing the peerage and the two church members, he noticed that Kiba had been through a human experiment to make exorcist able to hold holy sword. Tsuna was getting angry at that fact. He always hated human experiments. Nobody deserved such treatment especially innocent children. He wanted to interfere to punish those responsible for such experiment. Even if he hated Mukuro as much as his other guardians, no one ever deserved being submitted through those experiments as well as his friends.
Tsuna still enjoyed seeing the perverted idiot being punished for disobeying the order of their master. He may have a S side that could satisfied his feelings. He didn't want to admit but he kind of understood why his tutor took great pleasure at seeing people in pain.
Tsuna noticed that acquaintance of the perverted devil was being attack by the same exorcist that almost tried to rape the new bishop of Gremory. He felt himself obligated to help her as he couldn't let someone die in front of him. No matter how hard he tried he couldn't get rid of his sky attribute and so his good natured and his humanitarian side.
He used his flame to appeared close by the fight and before the rogue exorcist could deal anymore damage to the poor girl who had most of her clothes teared down, he leapt into the air while spinning around. With his leg outstretched, his foot kicked the rouge exorcist's arm and caused them to skid away.
"Ahahaha! Another piece of fucking scum came in my way!" Freed yelled, laughing and licking his blade. Irina who already was hurt a fair bit and looked to see who helped her. She saw the male uniform of Kuoh Academy with a young man quite handsome with brown straight hair who seemed to have some of it rebelling be a little spiky. He gave her his jacket to hide her state of undress silently, which made her blush and accept the vest.
"I didn't know that rogue exorcists were as perverted as devils." Tsuna said glaring at the exorcists as he noticed from the corner of his eyes the familiar of Gremory. Tangling his fingers while stretching his arms, he rolled his neck and released a few loud pops.
"I am just punishing that girl for following the wrong leader." Freed said as he behaved like his usual perverted self. Tsuna had a hard time containing himself from not burning the hell out of that person. "Plus, you shouldn't insult those who follows no one, right shitty rogue devil?" Irina was surprised by the information. From what she knew from the church, rogue devils were worse than rogue exorcist as they began quickly insane and feed from humans and anything they find themselves they craved for. But he didn't seem the slightest bit insane or bloodthirsty.
"Why do you stay here? You have the weapon you wanted." Tsuna said not caring a bit about them exposing his identity. He wasn't threatened by that man's presence, but he wondered about his attitude as he should have escape when he had the chance to fuse the swords.
"He is right, why are you still here?" A female voice that seemed to belong to Gremory asked. The three of the people present turned to the voice who really come from a magic circle, it was Gremory with almost all of her peerage except for Kiba who was still hunting the man who was near responsible for the blonde-devil's misery.
Tsuna slightly frowned at their quick arrival, he thought he would have his time to go before they noticed he was here. He should have known anyways. Since he investigated and intervened into the matter himself, he had to endure the consequence. It seemed that the pervert idiot didn't even notice him as he went towards the injured exorcist.
"Irina, are you alright? Asia!" He yelled as Asia came running to heal the injured exorcist.
"Don't worry! I am fine!" Irina said to them but Tsuna could tell she was faking it.
"You shouldn't listen to her. If her injuries aren't being heal in less than a hour, she would probably die." Tsuna said gesturing to the exorcist, making the male devil look back at him and finally notice his presence.
"Lonely Knight! What are you doing here?" Issei asked not knowing what to think of that boy that was an idol for most girls and an enemy for almost every guy. Frankly, he wasn't the only one surprise by that teen's presence. They always found him odd but he wasn't anything else than an excellent student as no magic or special aura was ever felt coming from him.
Tsuna looked a little bored at the situation, they didn't know who he was and what power he had. He bet they didn't even know his origin. Tsuna saw that the situation was under control as the student council president, Sona Sitri showed up. He didn't need to interfere any longer.
He decided to leave without so much as a word as he didn't owe them anything especially an explanation. For the next few hours, he completely ignored every question they had towards seeing that Sona Sitri took the injured girl to a healing chamber. But before he left, the sky changed color into a dark atmosphere clearing saying that fallen angel was coming. He looked back to see a fallen angel with ten wings clearly saying that he was a chief of strong power which would impossible for the two new devils and their peerage to take care. So, he decided to watch and see what happen. Plus, he would take some of his energy to escape this stupid dimension that the fallen angel created.
"Hello, we have never met before Gremory-san, sister of the Crimson Devil. I am Kokabiel." He said quite peacefully but aggressively at the same time. He was emitting a pure aura of confidence telling Tsuna that he could wiped them out in a matter of minutes. "Sona Sitri is present as well as Tsunayoshi Sawada." He said the last part smirking looking at him as if he knew something he didn't know.
"Hello to you too, Fallen Angel's chief. I am Rias Gremory. What is the point of this meeting? It is unusual for a chief to come to talk." Gremory said not flinching in front of the strong opponent. Tsuna was kind of surprised that she wasn't affected by his presence. But he knew that she had some doubt especially the part where he talked about mentioning his real name. She must have heard it from somewhere as well as Sitri.
"I wanted to have some fun around the academy, your domain in this city. Your brother might come to help you if it is too much for you, right? Plus, being able to see the fallen sky once again is a plus." Kokabiel said smiling, no smirking. This annoyed everyone including Tsuna but of course for different reason.
"That would only start another war between the three factions!" Rias yelled as she glared as it was the first concern. For Tsuna right now, he wanted to know how he found out about him and his past. Being to use the turn fallen sky must mean that he knew something about him. Plus, he used the term of again meaning he already saw him in his past life. This wasn't good, he needed to know but at the same time, he promised not to interfere. He would have to wait and find out later. For now, he guessed he needed to wait and see what was going to happen.
While Tsuna was thinking about what he said, he completely forgot about what was happening and didn't hear the stupid monologue of the Fallen Angel wanting to start another war for the purpose of his boredom. He was really stupid, he wondered if he actually knew about him. He just seemed like a common battle freak that just wanted fight to kill and not for any other reason, maybe also to show the superiority of his faction.
Where was this odd hit of nostalgia coming from? Oh right, that marshmallow-loving albino Byakuran. Both of them seemed to smile and smirk a lot to an end where Tsuna actually could swear their faces were frozen in such positions. They almost did whatever they wanted because they were bored. Heck, Kokabiel here even has wings like Byakuran, what were the odds in that department?
He understood that the fanatic decided to fight in their own school because it was the territory of two great family, the Gremory and the Sitri. Nobody could deny that it wasn't a good idea for starting the war. The crazy Fallen Angel continued to ignore his presence until he looked at him directly and said: "Fallen sky, you should witness it all. You might then understand why you sank this low to have to rely on that stupid rogue Nekomata devil, Kuroka, to run after killing your king!" This last part made most of the devils, except the recently reincarnated looked back at him as they all knew who that person was and what was her crime especially against the kitten.
"How do you know about that?" Tsuna said lowly and dangerous with his eyes hidden by his bangs. If he knew about that, what else did he knew about him?
"Well, I know almost everything about you. The Fallen Angels has been taken a great interest as you grow to become one of the strongest human who ever live. You needed to be taken care of." He said the last part smirking. "You were then reincarnated by a stupid devil who you killed without any remorse and escape with the help of that black cat. Should I add something to prove that I know you, fallen sky?"
"What do you mean by to be taken care of?" Tsuna asked very low and dangerously, most of the people around felt the temperature rise enough to make them begin to sweat at the heat that came from the Lonely Knight.
"Ahahaha! You will have to find me to learn more." He said as he threw light spears at them to make an escape. Most of them moved to dodge the attacks. But Tsuna didn't move as he used his flames to destroy or make the spear disappear.
"If that's the case..." Tsuna gripped his hands tightly to make fists. The sky attribute covered his forehead and arms like normal, but this time the rest of his body was coated in the dark flames that were as transparent as black ink. "The hunt begins."
