I do not own KHR or RWBY. Everything belongs to their respected owners.

After returning from the future Tsunayoshi thought things would come back to normal. Well, as normal as it can be when you were Tsunayoshi Sawada.

But he was wrong.

A few days later after their return, his mother, Nana Sawada, was involved in a car accident… and died.

His fa- 'Iemitsu Sawada' blamed him. Which was a stupid thing to do because Tsunayoshi was nowhere was nowhere in or near the vicinity when it happened, and instead at school.

His guardians left Tsuna alone with the excuse that they were giving him 'space'. In reality they were busying themselves with other things and made Tsuna see himself as a distraction. Hayato Gokudera, the loyal Storm Guardian, joined the Occult and Music club and was always with his new buddies. Takeshi Yamamoto, the peaceful Rain Guardian, returned to the Baseball club and was training them. Ryohei Sasagawa aka 'Onii-san', the bright Sun Guardian, managed to make a few people join the Boxing club and was getting them into 'extreme' shape. Chrome Dukuro was still living with Kokuyo gang but at least doing her best to live as a normal girl.

But Tsuna knew better. They were scared of him, his so called friends and guardians…

After all, Tsuna 'did' kill Byakuran in the future.

Why couldn't they understand that he didn't want to? That he didn't mean to? Why are they judging him like this? Gokudera was in the mafia way before Tsuna had been introduced, and could understand easily. He had told Yamamoto countless times that there was no mafia game and that at some point they would have to sacrifice lives even if Tsuna despised the mere idea of killing or even hurting someone else. Chrome, sweet and shy Chrome saw the brunette now with so much fright. Why was she looking at Tsuna like that?

Mukuro had killed entire famiglias and she kept looking at him like he had never done anything at all! Why couldn't she look at Tsuna like that too? What did the brunette ever do to deserve this kind to treatment? Every time the boy tried to talk with his 'friends' they would apologize and say they were busy doing who knows what before running away with their other friends. Even Kyoko and Haru. They even tried to keep Lambo, I-Pin and Fuuta away from him much to the younger children's confusion.

It hurt…

All of them were like that except Kyoyo and Mukuro – sometimes also Ken and Chikusa. They were the only ones that stayed by hos side, or at least whenever they could.

Kyoya at least kept an eye on Tsuna and bullies away from him since Gokudera and Yamamoto weren't, but he couldn't' be with him all the time. Mukuro was a slightly different case since he still at least had to take over Chrome's body in order to visit with the rest of his gang. But like the prefect, the Mist guardian couldn't be with her all the time.

At least the two of them had some excuses that made Tsuna completely understand and able to accept.

Reborn was a different story. The Sun Arcobaleno continued to stick with the brunette to the very end. Day after day, the infant would continue to train the young boy to be the Vongola Decimo. Yet despite Reborn efforts, Nono sent messages that the Sky cannot be there without the supporting elements. This only angered the Arcobaleno a bit longer and even forced the infant to take a plane to Italy after wondering why the Ninth was so insistent on such a choice.

Since Reborn had to go, it seemed that he assigned the Varia to aid Tsuna with his growth. Dino-nii as well, accompanied by Romarion of course, decided to also help with the training. Chaos grew temporarily in Namimori due to this however but it still made the growing Sky cheer up a bit. The young boy was able to gain much more respected from the elite assassing squad. Xanxus even stopped calling Tsuna trash.

If that wasn't progress, he didn't know what else to call it.

Reborn eventually came back however with an annoyed expression that was splattered across his normally neutral look, and the news irritated the new group close to Tsunayoshi as well.

KBT

The Vongola was celebrating.

Timoteo was happy to the point of crying.

It was expected though.

The late son of Nono, Federico, who was said to be killed under unknown circumstances and oly that his bones were found…, was alive and well. It really was unexpected. But no one could deny it, it was a happy occasion.

But during the celebration in Italy, Tsuna retreated away from the party and towards the hotel which was booked for him. He closed the door to his room behind him and sighed. Feeling a brush of warmth along his leg, he looked down and saw a familiar lion cub with Sky flames rather than hair along its mane and tail. "Hey, Natsu…" Tsuan smiled softly.

"Gao!"

Tsuna couldn't help but chuckle while bending down to carry the cub. "I've never seen Grandpa this happy." Tsuna said to himself as he stroked his Box Animals head while looking out a window. "But I can't blame him; I too would be crying tears of joy if I found out my dead son was alive."

But this fact made the boy close his eyes and a feeling of pain washed over him. Hot tears rolled down his face. He knew things were going to change. This was the news that Reborn had to hold. An heir for the Vongola position was back, one that members of the Vongola family would approve. Federico was a true-born Italian, Timoteo's favored son, and…

A perfect candidate to become decimo of Vongola.

Sure at first Tsuna didn't want to be the boss at all. No, not one bit. But now, he would be happy if he was due to all of the experiences as well as wanting to show all of the effort he and the others had put in. It was only a matter of time before he would have to return the Vongola ring though. His guardians would become Federico's. But what will happen to him though? Would his life return to how it was once before?

Rolling to the side, he quickly avoided a pair a feet about to stomp right on his face. Putting his guard up, the stance was lowered as soon as Tsuna recognized who it was. "Reborn…" The boy breathed in shock. He at least expected the Sun Arcobaleno to stay around the party. But what was the small man doing right here?

"Pack your bags, Dame-Tsuna, we're going travelling."

"Wh-what?"

This time, Tsuna's stomach came into contact with Reborn foot as the infant had kicked the boy in the stomach. "I thought that we at least got rid of your stuttering problem." Reborn stated, completely unfazed at suddenly attacking the boy.

Knowing that Reborn wasn't going to repeat himself, Tsuna found himself gathering all of his belongings without another word. A few minutes later, Tsuna had his suitcase ready and was about to open the door. But then he saw that Reborn had not moved from the position of observation which happened the be in front of the hotel door.

"Your ring, Tsuna, take it off." Reborn gestured to the accessory on the boy's finger. Now that completely stunned Tsuna for two completely different reasons. The Arocbaleno had said his name without the nickname, meaning that he was serious about something. Second was about taking off the ring due to pretty much wearing it 24/7 after such a long time. "I have been informed by Nono that you are to return the ring as you are no longer a valid candidate of being the Vongola Decimo…"

A long period of frozen silence took over, but the boy nodded his head in understanding. This still didn't please the Sun Arcobaleno as Tsuna took off his ring and handed it over. The Arcobaleno brought out a small case and stored the accessory inside before walking out of the door without another word.

Silently following the infant, Reborn placed the case in a plant vase nonchalantly before taking out a small package. Handing the object to Tsuna, the boy decided to stuff it into his pack. They continued to walk out of the hotel, without checking out, and stepped into a small limo that began to drive away from the building.

"Reborn… Just wh-"

"You are going to be my apprentice." Tsuna was cut off by Reborn's blunt answer. That single sentence sent the young boy speechless. Tsunayoshi was going to be the apprentice of 'the' world's greatest hitman? Wasn't he technically already that though? "You were only a student, just like Dino." Reborn answered, as if reading Tsuna's thoughts. Though really it was just being able to have a good chance about thinking how the person your reading thinks. "But now you will be under personal tutorage with my choice of teachings rather than a straight forward one about being a boss."

"I… I don't know what to… Just… T-thank you… Reborn…" Tsuna finally managed to find some words at least, despite the stuttering that was in his voice. But since Reborn didn't try to hit him for it, he guessed that it was at least a moment he should take advantage of and not mention such a thing. "But, where are we going to go? If I remember correctly from your teachings, the Vongola has establishments all over the world."

"That still doesn't mean they will have an easy time finding us." Reborn answered, getting a surprised look and a request of explanation. He knew that Tsuna was trying to take advantage of his rather generous mood at the moment, but he may as well. The brunette would find out eventually under his teachings. "We're going to the country called Remnant which is made up of four 'Kingdoms'. It is a rather difficult area to understand that the Vongola has not delved into yet. It should be the perfect place to stay for the moment."

"Remnant…" Tsuna parroted.

If he remembered correctly, Remnant was supposed to be a mass of islands in the middle of the Atlantic ocean… sort of like the islands of Hawaii. Also, like Hawaii, their islands were named separately… well more like their Kingdoms. But that was beside the point at the moment.

Suddenly, the limo stopped and the two of them walked out. Looking around, Tsuna saw that they were at an airport. Or rather, an airstrip/runway where many planes were sitting on the ground. One seemed to stand out as there was a group of familiar people waiting for him.

"The Varia?! Dino-nii?! Mukuro?! Hibari-san?! The Arcobaleno?!" Tsuna questioned as he saw each person from said groups waiting for him at the entrance of the plane. Once again stunned, he was lucky Dino was the one to snap him out of it.

"We're here to see you off. Sadly, I can't go away without being suspicious." Dino apologized. "The same could be said for the Varia, Mukuro, and Hibari-san."

"Kufufu, I'm just here to let you know that I'm not planning on possessing your body any longer." Mukuro chuckled in amusement.

Hibari was standing off to the side far away from the ground. But Tsuna knew that the cloud Guardian meant well by at least seeing him off. Only the slightest of nods however was seen and acknowledged.

"Brat, you better stay in shape. I didn't lose to you so that you could slack off and give the position to someone else." Xanxus growled.

"Ushishi, the Prince bids farewell to the great peasant."

"Vooiii! Just get the hell out of here already!"

"Good-bye little Tuna-fish!"

"You better not disappoint the boss!"

Tsuna only smiled at each and every one of them. But then something clicked in his mind about what Dino had said. "Wait, Dino-nii said him, the Varia, Mukuro, and Hibari-san can't go. Then what about…" He trailed off. A thought slowly dawned into his mind as he looked over to the Arcobaleno.

"Be grateful that I'm doing this for a minimum fee." Mammon sighed.

"It would be an interesting experiment to see you undergo all of our tutorage at the same time." Verde adjusted his glasses.

"Lal and I are going to make you into COMSUBIN material, kora!" Colonnello exclaimed with a determined look.

"You better prepare yourself, brat." Lal stated with a fold of her arms.

"You should feel honored that I, the great Skull-sama, am even glorifying you with my presence." Skull shouted.

"You saved the future, it's the least we could do." Fon bowed.

"Sadly I cannot come along. " Aria sadly smiled. "I doubt that I could be of help anyways."

"What are you waiting for, Dame-Tsuna?"

Tsuna's attention was then brought to the plane where Reborn was already inside and waiting for the boy to get back in. Slowly taking steps up, he looked over towards the small crowd of people and the long figure a small distance away. "Everyone, thank you for everything!" He shouted while waving before getting into the plane.

Walking along the aisle, he could see a couple of members waving him goodbye. But as he stored his things, the plane was already taking off and into the vast sky. "Actually, Reborn, I've been wondering something. Won't the Vongola notice the almost all of the Arcobaleno are missing?"

"Which is why I said that you should be grateful I'm doing something like this at minimum wage." The Mist Arcobaleno grumbled.

"We only got one year to get you into tip-top shape, kora!" Colonnello told the boy.

"So you better prepare yourself, Dame-Tsuna." Rebron had a smirk slowly grow on his face.

Despite the happiness turn into feeling helpless, he was still thankful for their aid.

KBT (One Year Later)

A 15 year old Tsuna took time to subtly marvel at their surroundings.

It looked like a grand castle. It was perhaps even bigger than the Vongola mansion. To a bit of his partial distaste though, he still did not mind it however, the color white overgrew most of the land. Thanks to the experiences of a certain Byakuran, white was not exactly a color Tsuna was fond of.

"Dame-Tsuna, stop staring and follow me." Reborn snapped the boy into reality.

Tsuna immediately straightened his back and began to walk forward with the infant. As they approached the gates, two men in white uniform (Tsuna wasn't surprised) quickly stopped them in their tracks. "Stop! State your name and business!" One of them shouted out.

"My name is none of your business. We are here to see Mr. Schnee, head of the Schnee Dust Company." Reborn easily answered with a straight face. Tsuna internally sighed at the typical answer provided by the world's greatest hitman.

The two guards each pulled out a small handgun but then were stopped by a voice. "Halt!" Thanks to their gazes not even moving towards the guns or guards, Tsuna and Reborn received a good view of who called out the command.

The sight before them was a tall, young woman, with pale skin, white hair and medium-light blue eyes. Her hair was tied up in a bun at the back of her head, with the exception of her bangs, which were brushed off to the right side of her face. A small lock of her hair reached below her left ear. By the looks of clothing, she was dressed in some sort of custom military uniform.

The woman took the time to look at the two sudden guests. One of them being a brunette about the age of a teenager, the second being a mere infant. "What are your names?" She asked in a curious tone.

"My name is Reborn, and this is my apprentice Tsunayoshi. I believe I have an appointment with the head of the Schnee Dust Company. I believe he is also your father, Winter Schnee." The infant answered.

The woman now known as Winter had a small frown of thought etched on her beautiful face before it turned into a neutral gaze and nodded her head. "You are correct. If you may follow me, please."

Following once more, the two non-Remnant inhabitants walked through the grand halls before coming up to a rather large door. Winter knocked on the door and the sound echoed against the walls. "Come in." A voice allowed them to enter to reveal a man with white mustache and white jacket sitting in a chair behind a brown desk.

Tsuna then made a small joke about something finally not being the color white.

"Ah, Mister Reborn, how are you?" The man asked, who was presumably Mr. Schnee. "Winter, we're fine thank you."

"Of course, father." Winter bowed before taking her leave.

"You can tell how surprised I am to get a sudden video call from the world's greatest hitman himself. As well as his… change in appearance." Mr. Schnee continued, glancing towards the standing brunette near the entrance to the room. "So tell me, why is it that you are here?"

"I'm here about a favor you owe me… among several if I may add." Reborn stated, getting a sigh from the older man himself. Since Mr. Schnee didn't answer, the infant knew he could continue. "I want you to employ my apprentice, Tsunayoshi, here as a tutor here for the Schnee Dust Company."

Now this was something that Tsuna did not expect and whipped his head towards Reborn's being. Despite needing to be professional and polite, he couldn't keep himself contained. "Reborn, what are you talking about?!"

"Yes, an explanation would be much appreciated." Mr. Schnee agreed.

Reborn looked like he wanted to beat Tsuna for a split-second before containing the urge in favor of the reason. "Because, you need to take the next step in your tutorage. If you only do what you can do, you will never be able to be who you truly are."

"Speaking cryptically is not your thing." Tsuna responded.

"You want to learn more? Teach others." Reborn deadpanned.

Mr. Schnee meanwhile took amusement to the small conversation between the two of them. "Very well." He answered, grabbing their attention. He then pressed a button on a small machine. "Weiss, please come visit me in my office." The man took his finger off the machine and faced the two of them. "If you have such faith that he will do well, than who am I to doubt? However, a simple tutor isn't much. How about the position of a butler as well."

"Sounds perfect." Reborn responded without Tsuna permission. "I leave Tsuna in your care. Ciao ciao."

"Reborn, you're just leaving me here?!"

The infant simply kicked Tsuna shin, making the boy drop onto his knees. "Dame-Tsuna, I am doing my best to be a good teacher to you. But right now, there is nothing I can teach you. It is better for people to learn things on their own or with a shove. This is my version of a shove, alright?"

"…" A hesitant nod was all Reborn needed.

But before he could leave, there was another knock on the door. "Come in." Mr. Schnee called out and the doors to reveal a girl Tsuna's age.

The young female was dressed in a pale blue bolero jacket over a similarly colored thigh-length dress with a piece of black lace making up the neckline of the dress, which was a combat skirt. The inside of the bolero was red with sleeves turning blue as they got closer to her wrists. The bolero had a crest on the back that bears a resemblance to a snowflake but with jagged edges. She was wearing an apple-shaped necklace along with a pair of thing, rectangular earrings along with white, heeled wedge boots that go to mid-calf, also lined with red on the inside. Her long white hair was pulled back in an off-center ponytail, at the base of which is a small tiara that resembles icicles. She also had a pale complexion and ice blue eyes. Finally, there was a small bag on the back of her dress wrapped around her waist with a ribbon.

"You requested for me, father?" The girl asked.

"Yes I did, Weiss. Tsunayoshi, I would like you to meet my youngest daughter, Weiss Schnee. Weiss, meet your new tutor, and personal butler." Mr. Schnee introduced the two of them.

Immediately remembering how he needed to act as a gentleman, Tsuna bowed formally. "It is a pleasure to meet you."

"Thank you, as it is for you." Weiss bent her knees in a lady-like fashion.

"I'll have someone come and show Tsunayoshi to a place he may be staying. Until then, may I ask that you wait outside?" asked.

Tsuna nodded his head and bowed once more before exiting the room with the other two occupants following. "Reborn, where will you go then?"

"Back to Italy." Reborn answered. "The Vongola may be suspecting something so I am going back as soon as possible." The infant turned around and looked directly into the male's eyes. "You better do well or else you'll be putting me to shame, Tsuna. You know what will happen when I find out."

"Then I believe it's best that I do not reveal such a sloppy performance." Tsuna smiled. With satisfaction filled thanks to that answer, Reborn walked around a corner and disappeared. Seeing as how it was just him and Weiss, he faced the heiress. "So-"

Before he could continued on with his sentence, he was jabbed right in the stomach. "You're not my friend, you're a servant. Make it past two weeks, I might bother to re-learn your name so I may put just the slightest bit of effort to even bother remembering it. Until then, you're nobody to me."

Tsuna only sweat dropped as he saw Weiss walk away arrogantly.

SPECIAL THANKS TO Mia Heartnet FOR PROVIDING ME WITH SUCH AN INTRO!

Don't worry, I got their permission and am hoping that I did not disappoint them… Which I sadly think I did.

I know everything happened a bit fast, but I hope that you all at least understood what was happening.

No flames please!
