I don't own Katekyo Hitman Reborn and Percy Jackson and all the books linked to it, I only own my story.
Most of the demi-gods were surprised by the flames, but they mostly wondered if they had another Leo in their ranks.
"Tsuna, go for the win!" Piper said cheering for the newcomer. It made most people wondered about their relationship. Annabeth could have guess that she would say that she is under his wing maybe as her boss or something. It had to do with Vongola.
"Too bad, this state makes me want to fight him even more, right Thalia?" Percy asked her cousin, excited to fight.
"Yeah, you are right." Thalia said wondering the strength of the guy.
"Well, you can if you want." A little voice from behind them told them.
Both of them turned to see the little kid that was arrogant in front of the gods and didn't hold back to kick the new kid. He smirked at them.
"You can participate in the fight, but in exchange you must teach him archery and swords fight." He said still smirking.
"Awesome/ Fine." The two of them agreed as they join the fight.
"Good then, it's everyone on his own. The one who remained standing in the hand wins." Reborn announced.
"This is getting harder." Tsuna said looking at Reborn.
"Are you scared, kid?" Clarisse said tempting the newcomer.
"Of course not. However, Natsu, I don't want you to participate in the battle so can you go stand next to Piper?" Tsuna said which made people wonder who was Natsu.
They suddenly heard a "Gao" coming from his hand and saw little lion cub appeared from it. The lion cub had a flaming mane. It walked towards Piper until it jumped into her arms.
"Long time no see, Natsu! Too bad you can't fight since it's one person against one. But you can play with Mrs. O'Leary, she is friendly." Piper said as she showed it the big hell dog, that really scared the cub. "Don't worry, she isn't dangerous."
"You can't really make him do that, they may cause some damage playing around. Plus, he should start his training right away." Artemis said as she took Natsu from Piper's arm, "You can play a little with my wolves. They are going to teach you how to hunt." She looked at Natsu with a smile that reminded him of Reborn, which made him want to run away from her but she had a tight grip.
"Gao! Gao! Gao, Gao!" He yelled at Piper to save him, who only looked away from him as she felt guilty and said: "Good luck, Natsu! See you later!"
Tsuna felt worried about his partner but the gun behind him, curtesy of Reborn, made sure that he didn't turn his head and concentrated on the fight. Tsuna decided to stay focused on the battle:
"Let's begin our fight." Tsuna said seriously.
"Let's!" The three others decided. They all draw their weapon, Percy his sword, Clarisse her lance, Thalia, her lance and her shield.
Clarisse decided to begin the fight first as she charged Tsuna. Percy and Thalia awaited to see how would the new boy reacted to the charge. Clarisse put her lance first, to their little surprise, he caught the lance with one hand. Clarisse smiled at that preparing for him to be electrocuted.
Tsuna let the lance quickly after a second of being electrocuted, Clarisse used this opportunity to finish her opponent. She prepared to pierce him with her lance. But before she could even scratch him, Tsuna quickly got the sensation of his hand back and disappeared in the eyes of Clarisse.
Thalia saw him reappear behind Clarisse, she used the opportunity to strike. Percy saw her doing that but stopped her with a strike of his sword clearly telling her that he was his prey. Thalia easily stopped with her shield, Aegis.
Tsuna smiled at the movement being stop., but because he turned his attention to the other two, Clarisse had time to noticed him behind her and did a spin on herself to strike him with her lance. Without looking at her, he took a step back.
"You have good instinct." Tsuna told her making her angrier at him. He was clearly underestimating her. She continued striking him with her lance, as he continued to dodge it nonchalantly. She got so angry that her war aura activated but not completely as she didn't want to kill him and made Tsuna unable to dodge her more unpredictable and faster movement. He had to parry it with his gloves making sur that he would making him electrocuted.
Clarisse know that she was going to win as he began to continue to par it making his body number. She finally saw his body slowing down and decided to strike for the kill.
When she prepared to strike for his leg to making him stop moving, she stopped her movement and took a step back. Her instinct screamed 'Danger! Danger!'
"Who are you?" Clarisse said as she glared at him.
Percy and Thalia stopped their bickering with their swords to understand what happen. Most people thought that Clarisse had won. Only the people who knew Tsuna smiled understanding the situation.
"You have good instinct. If you would have done that attack you would have lost." Tsuna said seeing her movement. "If you are done, then it's my turn to attack." He said as he walked towards her.
Clarisse stood her ground and prepare for his attacks. Tsuna continued to walk towards his opponent. Tsuna then ran towards her, and began throwing punches at her who did her best to dodge or stop his punches.
"Let's get a little more serious." He said as his right punch enlightened with an orange fire, producing a strong punch towards her which she parried with her spear bending the spear making her fall backwards.
Thalia decided to intervene seeing an opening from Percy and Tsuna. She decided to strike the last one with her thunder. Tsuna, seeing that attack he moved rapidly due to his flames, but this time Thalia knew about it, so she prepare to attack as she followed his movement with her eyes to prepare to strike him.
As he reappeared, she stroked that place, but he was prepared for this and parried it. He hit the spear making the end hit the dirt of the ground. He punched the shield not as heavily as Thalia would have thought. But her instinct told her that something was up, and it was confirmed as he said.
"X-Burner 5%." He said making Thalia who hid completely behind the massive shield, projected a few feet away from her because of a strong propulsion of flame.
It surprised the people watching the attack wondering why a second before, they saw him creating a flame behind him, but they understood more as he produced a stronger flame in front of him.
Thalia put her knee on the ground as she didn't expect such attack. Percy looked at the two of the strongest fighter he knew were on the ground because of one new guy.
"You are strong. I may need to get serious." Percy said happily, "Maybe the two others shouldn't have underestimate you. Well, we didn't think that you were that experience."
"To be fair, we don't have the same experience in fighting and training. You people seemed more used to multiple strong opponent, plans and teamwork, I am used to one strong overwhelming opponent." Tsuna told him nonchalantly.
"How do you know that?" Percy asked, wondering about their experience in a fight.
"Tsuna has an intuition that he herited from his ancestor that can give him a lot of information. That is why he can dodge any attacks without looking." Piper explained to Percy.
"Interesting, I am wondering how long you can last." Percy said preparing to strike and to par with his sword and the shield which his brother made.
Tsuna prepared for his attacks, but before anyone of those two could strike, a white light flashed next to the two of them. In the same time, snow began to fall around that light. Piper, Leo and Jason realized quickly who it was which made the two males prepare their weapons. The light disappeared leaving a brunette woman with skin as white as the snow and brown eyes.
"Khione!" Leo yelled. Most people now knew who that person was including Percy who smiled at Tsuna as he said:
"Sorry, but it seemed our fight is going to be delayed." But as he looked at Tsuna's reaction, he wasn't into a tense position or even surprised, he just looked tired and exasperated by something.
Annabeth seemed to also see his reaction. She wondered if he already met her, but as she looked at Piper, who should be angry seeing her as she tried to kill her every time they met, was putting a fake smile as she felt sorry for someone.
"Tsuna-sama, sorry to disturb you." Khione said as her eyes landed at Tsuna and she kneeled in front of him.
"What is it?" Tsuna said even more exasperated.
"Reborn told me to bring you any work that your guardians may have cause during their missions." Khione said without a lot of emotion.
"Yes, but they should have just left only a day ago. How much work could they have produce?" Tsuna said clearly irritated returning to his normal mode with his brown eyes.
"Well…" Khione said with a little nervous for some reason, with one movement of her hand, three piles of paper as big as her. "The first two were caused by Hibari meeting Xanxus in the mission and Mukuro working with Byakuran, the last one was curtesy of the rest of your guardians except for Chrome.
"What?! Why did Reborn put them together?" Tsuna yelled changing his normal scared attitude into a mad one and changed into weirder one when a scary smile crawled up on his face. "I swear when I meet them next time, I am going to torture them. I am going to enjoy torturing each one of them including Byakuran and Xanxus."
Khione seemed to not be affected by that attitude, but the other people around him took a step back from him frightened by his attitude. Piper walked towards Khione and asked:
"Do you have any good news for us?"
People were surprised that she wasn't scared or even cautious about the snow goddess. The immortal being looked at the demi-god and said:
"For someone like you, of course not. I only agreed to follow and to help if possible Tsuna-sama." Khione said a little angry at the girl in front of her.
"Not my fault, you decided to attack me and ended up facing Tsuna and submitting to Vongola." Piper said smiling as she had a higher position in Vongola than her.
People were left dumbfound by the situation in front of them, old enemy were standing there arguing like they were just love rival or something like that but not mortal enemies. Annabeth began to ready wonder how amazing was Tsuna, to be strong enough to be the best fighters she knew on her knees and made a goddess submitted to him.
Well, right now he seemed just angry at the paperwork in front of him. He seemed to be hesitating of burning the paperwork but he was stopped by a bullet scratching his cheek.
"If you tried to burn one of them, I will shoot a bullet through your skull and will augmented your paperwork tenfold. And you better finish those papers tonight, or else." Reborn sad with a smoking gun.
"Fine…" He said grumbling. "Khione, put them in the room where I am staying and if there isn't desk, put one there. After, you are free to do anything you want, until something else comes up."
"Of course, Tsuna-sama. Please feel free to call me if you need anything." She said as she left in bright light with the paperwork.
Tsuna sighed at the work he had to do. He, at least, thought that he might have had on day off from paperwork but his guardians didn't agree to it.
Piper recomforted her friends as he seemed depressed from the papers he saw. Even for Annabeth, it seemed a lot to do in one night.
"To think that you would tame a goddess yourself, Reborn, you truly have an amazing student." Chiron said appreciating such a human.
"Well, he is okay, but he isn't at a acceptable level of discipline. I may need to raise my training level or his pride might get to him." Reborn said not impressed.
Tsuna was even more depressed at what Reborn said. Piper had a hard time not laughing at his reaction, but it didn't stop Percy from laughing:
"You are truly a fun guy, but I don't know how you could do that much work, you got to be a child Athena to be able to do that."
"Don't be stupid, even child of Athena would consider paperwork torture." Chiron said knowing what he was talking about. "But I am surprised of how low was the pile of papers today."
"That's because they just began their mission, they mustn't have destroyed the city yet." Reborn said smirking, "Plus, Nono still does some of the work."
"Oh okay, I understand. He is going to have a hard time as the don." Chiron smiled.
"Of course, I won't let any of my students have a relaxing life." Reborn said smirking.
Tsuna was even more depressed. But he saw two pair of feet in front of his head. He looked up and saw his previous opponents, Thalia and Clarisse who were both glaring at him. Clarisse was the first one to speak:
"Don't think you have won just yet. We will continue this battle later." She then left from the Arena with a boy who quickly followed her trying to recomfort her.
"She is right, you still haven't won. But I can say that you are quite interesting, I can't wait for another and I will be prepared to win. And since I promised your tutor, you better not be late tomorrow for your archery lesson with me." Thalia said happy to have found another interesting opponent, plus, she understood more clearly why was Artemis interested in him.
Tsuna sweatdropped as it seemed people were already wanted his head even if he just arrived a few hours ago. Why did the gods hate him this much?
"Then now that this is over, you can have some free time everybody, but don't be late for dinner." Chiron announced to every camper.
