Chapter 4: The Flames of Heart's Billions of Souls' Blessing

Author's Notes: This chapter has not yet been edited or proofread. Please read it at your own risk.

Tsunayoshi's a slightly mysterious being in this city.

Some people love him to death while some just can't stay in the same room with him due to reasons unknown to everyone else but that person.

However, you can say that 99% of all people in that city like him more than anything else. If only for the fact that when the Arcobaleno Prince's feeling mischievous and wanted to create Chaos, he was there to tone it down even without knowing it. Much to the happiness and gratitude of the citizens in the city.

Everyone in the city knows about him because he was the one that adopted the three children that the Estraneo Famiglia had experimented on - something which caused heads to turn with gaping mouths opened. Aside from that, everyone in the underworld knew about Tsunayoshi because his shop was the favorite shop of half of the Arcobaleno Demigods. And there is no one who was willing to mess with him either because of the Arcobaleno Demigods or just because they all respect Tsunayoshi too much to do so.

Nowadays, there's a long line of people waiting outside for food, drinks, and just being near the store in general. They chat happily even though they are tired from working days in and days out.

The store's menu has changed for the first time ever since it was opened by Tsunayoshi a couple of years ago. So, people were curious about what has changed. Which was why, today, there was a long line of women waiting outside.

Just last week, the store was closed for the whole week because the kitchen was being renovated. When it opened today, it caused the crowd to be so excited that the door nearly burst open.

Thus, the current situation.

Tsunayoshi has changed the interior of the shop and added a couple more devices into the kitchen area. Now he can make baked foods and snacks. The front both has more room for more sweets and more Ready-to-Eat lunch such as sandwiches and soups. The side room, which was connected to the next building, was expanded into an attached room. So, there were more rooms, chairs, tables, and space for more people.

That's right, pals. Tsunayoshi brought the building attached to his current house. Thus, allowing him to modify the two buildings and connect them together into one.

As a result, the small shop has now turned into a full-blown restaurant, if it wasn't one already.

They now serve a couple of dishes from more than one culture, so the amount of clients has been increasingly raised far too fast.

This caused Mukuro to be both proud and yet pissed off because Tsunayoshi's time was mostly used in preparing the so-called different culture - foods. Thus, he has less time to spend with them.

Over the period of 3 months, Mukuro can now say with 100% truthfulness that he was very fond of his bigger brother, Tsunayoshi. He has his odd moment of going into a trace whenever there was no one to see it but the majority of the time, Mukuro has a feeling that he was slowly healing. From what? Probably from losing his husband. The one that looked like the Arcobaleno Prince, Reborn.

Mukuro wasn't blind. Hell, with memories from more than 6 lives together, Mukuro was never going to be blind.

He saw how the Arcobaleno Prince looked at his older brother. He saw how Tsunayoshi's eyes twitch with pain sometimes when he looks at him and the kids.

However, what caused Mukuro to be surprised was that after that night with Reborn, his older brother's aura changed slightly. There's this sweet smell of magic coming from Tsunayoshi sometimes when he wasn't paying attention.

The smell was sweet enough that it caused Chikusa and Ken to go into a daze whenever they smelled it. Mukuro? He has some control of his own body but it was hard.

And then, as sudden, as the smell comes, it was gone as fast too.

This caused Mukuro countless confusion.

And still does.

Tsunayoshi internally sighed in relief as he controlled his magic aura.

It has been more than 3 months already since that night with Reborn's father and the Awakening of his Magic abilities in this world.

And Tsunayoshi was finding it hard to control his Magic Abilities.

The ability to learn any language, the ability to appraise anything, the ability to create anything using magic, the ability to grow mentally, and make sure that his spirits don't get tired too easily, among a couple of other abilities...

Especially finding out that Tsunayoshi now has the bloodline of the Fire God and Blessing of Trinity's Soul-Link.

If that wasn't enough, finding out that he can use all Elemental Magic was even more headache-inducing.

All these abilities and traits caused Tsuna's blood to be very magical, in a sense. So, when Tsuna wasn't careful, a very sweet scent would come from him. Which caused a lot of trouble for Tsuna.

Why? Because his magical scents were even more troublesome than Sky Attraction. The amounts of people that were drawn in were not limited to humans and Flames Active.

Yes. Demons are attracted to it, too.

Which results in the current situation.

A Reborn, his father, and 5 other demons in the same room.

Tsuna sweats drop in the atmosphere in the room, which is filled with magic.

Reborn was looking at his father with an intense look in his eyes, which has already turned gold. Reborn's father, who was in human clothes, was sipping on coffee without a care for his son's glare. The 5 other demons were someone who looked like Yuni but far older and didn't have Giglio Nero's big white mushroom-shaped hat. And she doesn't have the Giglio Nero Famiglia's emblem below her left eye. Otherwise, she looks like a much older Yuni. All except her personality.

Well, there's a reason why she's the Reborn of this World's Boss, alright.

And then, both Aria and Yuni were also here along with a male who looks similar to Byakuran- just without the purple tattoo under his left eye. Who, by the way, was grinning in that very mischievous smirk of his that caused Tsuna to twitch. It reminds him of a mixture of Reborn when he's feeling like creating chaos, Mukuro when he's feeling mischievous, and Byakuran when he's feeling a little too excited. And that was not a good combination no matter what other Famiglia said about it.

The last time that Yuni was here, she was with Luce and Aria. However, this time, there's a Byakuran here with them.

Byakuran, the White Blood Demon. He's half Demon-half-Angel.

When Tsuna first saw the Byakuran of this world, he was arguing with a shop owner over a box of marshmallows. The man was wounded from a fight with a contracted demon over a packet of marshmallows. Of course, he won but it was a pretty close call. Especially when it looks and feels like there's a sealed place over Byakuran's Eyes and magic. So his strength was a lot weaker compared to other demons.

Tsunayoshi had wanted to ignore the fight but- damn his bleeding heart- he didn't want to see bleeding or hurt Byakuran and he especially doesn't want to let Byakuran hurt someone else. So, he steps in. In exchange for the contract demon to let Byakuran have the marshmallows, Tsuna would make a strawberry marshmallow cheesecake for the contracted demon.

Of course, when the half demon-half angel heard that, he threw the bag of marshmallows into the contracted demon hand and dragged Tsuna away.

In the end, Tsuna has to make Byakuran a Strawberry marshmallow cheesecake. Everyday.

Since then, the halfling had come to his shop every single day without fail.

However, this was the first time that he was here when Luce, Aria, and Yuni were here at the same time.

The staring contest between the four of them was enough to cause everyone to give them a wide area off.

Hell, even Tsunayoshi could feel the magic in the air. It was tense and with a hint of bloodlust but it wasn't with killer intentions.

Ken and Chikusa keep inching away from the area that those demons were sitting in, toward where Mukuro was helping an elder woman with her order.

Sighing out loud, Tsunayoshi tried to calm down his agitation and went to grab the cheesecake that Bykauran wanted, along with the three ladies' orders.

Luce was having a lemon-raspberry tart, Aria was having a blueberry pie, and Yuni was having a berry-shortcake slice.

As for the Father-and-Son Pair, Tsuna would like to pretend that they don't exist right now.

"Here you go," Tsuna said as he placed the orders on their tables. Byakuran's eyes shined at the cheesecake with enough cheers to cause magic to flutter around him. Tsuna would like to pretend that there were no wings behind the white-haired boy and leave it at that.

"Tsu-chan~! Marry me~!" Not for the first time ever since Byakuran tasted Tsuna's cheesecake, he proposed once again. And no, he wasn't joking. Tsuna knows that instinctually. And he knew that Byakuran really does have some sort of feeling for him, too.

Tsunayoshi calmly patted the man's head, "Sorry, Byakuran-san, I am already married and is happily in love with my husband," Tsuna replied to Byakuran fondly.

This was his answer to Byakuran's proposal every time. This Byakuran isn't his world's Byakuran. However, Tsunayoshi had already long ago claimed Byakuran as one of his own. Even when those marshmallow addicts caused him countless headaches and paperwork, Tsunayoshi still does care for him. And he knew that his world's Byakuran also cares for him, too. Like a Brother-in-Trinisette-Relationships.

The Byakuran of his world has to put a limit on his emotions. He has to limit his feelings for Tsunayoshi to only being a Brother. After all, by the time that Byakuran noticed that he cares for Tsunayoshi, Tsunayoshi was already in a stable relationship with Reborn. So, he cut off his feelings and put an end to it. Brotherhood? Yes. Love? Yes. In Love? No. Never. Byakuran was not stupid. He was very fond of Tsunayoshi, even more than Yuni. But, in love with Tsunayoshi? No. Just- No. Maybe in another world, yes, but in his world? No.

This was why Tsunayoshi was just slightly surprised that the Byakuran of this world has a crush on him.

The Half Demon- Half Angel pout at Tsuna with a spoonful of cheesecake in his mouth.

Reborn was watching from the other table with a gleam in his eyes. His father too was also watching Tsunayoshi's interaction with the halfling.

"Thanks, Tsuna-nii~" Yuni cheekily said as she completely ignored the man in front of her for her sweets.

Tsunayoshi completely ignored Reborn and his father as he went back to tending customers.

It is right now June 12, the first day of Summer Break for school.

Mukuro, Ken, and Chikusa all were so happy that they didn't have to go to school during Summer Break.

The timing was just right too, as the remodeled store was just finished yesterday. And their help around the store was much appreciated.

Mukuro, Ken, and Chikusa were already at the end of their La Scuola Primaria (primary school). When they stumbled into Tsuna, they were only 5 years old or so, but now, all three kids were already 12 years old.

And Tsunayoshi had already been here for 5 years.

Five whole years.

Five years of being separated from his Guardians, Elements, Family, and Reborn.

Tsunayoshi is still not used to being here in this world.

He doubts he will ever do it.

Five years.

Five fucking damn years.

A couple of times, Mukuro found Tsunayoshi crying during sleep. Sometimes, it would be Chikusa. Ken has never found Tsuna crying in his sleep, before. Although Ken found him a couple of times feeling solemn and melancholy, Ken was never one to ask for the reason why. All he did was sit by him and quietly stay there.

So far, all three kids knew that Tsunayoshi had already married someone who looked 95% like the Arcobaleno Prince, Reborn. Only that his husband was pure human. Well, they didn't know that Reborn, his Reborn, wasn't 100% pure human anymore because of the damn curse.

In these four-five years, the Arcobaleno Prince had been trying to get Tsuna to date him. Hell, ever since that time in Hell, Tsuna has been very careful with Reborn.

Reborn has been spending more and more time in the Human World within Tsunayoshi's store. It was to the point that all of the Arcobaleno knew where to find him if they needed him.

Still, Reborn has been getting very good at controlling his demonic power due to Tsuna's reaction toward his feelings.

Eventually, Tsuna knew that he would properly slip one of these days and agree to go out with the Reborn of this world. But he also knows that it wouldn't be anytime soon. After all, the Arcobaleno Prince was not joking with his emotions.

Reborn is the Strongest Arcobaleno Prince. He is a demigod. And one of the Strongest 7 Demigods. Saying no to him was like saying no to a large bounder. So, Tsuna kind of knows that eventually, he would slowly fall for this Reborn and slowly move on. But until then, he would fight for as long as possible. He would be faithful to his husband, even from another world.

Tsuna has been researching the powers that he has been given.

The ability to learn many languages, appraisal, creation magic, and the other abilities were well speaking about. What caused Tsunayoshi to have confusion was the Blessing from Five Billion Souls and its ability.

He knows that it influences the growth rate of the subject/object inside his Flame Space. The plants that he grows inside were larger, vitalized, more abundant, and taste better than any magical cultivated farm in the real world.

He also knew that those Billion Souls had influenced his training speed. He had already learned how to use all the Elemental Magic and has a very high proficiency with them. It was easy for Tsunayoshi to understand the 8 elemental magic, how to train them, how to increase his proficiency in them, how to minimum mana but still cast spells strong enough.

It was so intuitive for Tsunayoshi that he found it weird. Even with Teleportation Magic and Time Magic. It was like Tsunayoshi had already learned these kinds of magical combat methods before. But, he knows that he hadn't learned them before! He was a normal human until Reborn came in with his guns and chaos magnet.

So, it confuses him that he was able to intuitively use magic like it was already his own soul. Not to mention, understand it the way that he does.

Aside from the magical magic that he was able to use and the Billion Souls' blessing, there was also the Bloodline of the Fire God.

Even though he was able to use all the other elemental magic with very high proficiency, what Tsunayoshi found himself liking was the Fire Magic and anything that had to do with Fire.

His Proficiency and Mastery over the Fire Element magic was especially strong. Too strong, in fact.

His techniques with the Zero Point Breakthrough: First Edition and Revised Edition were 100 times stronger than before. So, he had decided that these two techniques can never be used again.

These two techniques aren't the only ones that got power up. His X-Burner, Condensed X-Burner, X-Stream, Burning Axle, X-Cannon, and Flame-Enhanced Punches were all stronger than before by at least 90 to 98 times.

Now, if Tsunayoshi wasn't careful, he could and would accidentally purify food into stone or upgrade their taste so much that it causes multiple reactions within people's bodies!

For example, a couple of weeks ago, Tsunayoshi had accidentally infused too much Sky Flames into his newly created cake and caused Mukuro's magic ability to shoot up through the roof! If that was it, then there wouldn't have been a problem. However, the fact that Mukuro's Mist Flames, or Mist Magic as it was called in this world, was getting even more purer... This had caused his control over his power to slipped slightly and nearly caused a disaster in this neighbor.

So, Mukuro had to train his Will and Control all over again. Much to his happiness.

After Mukuro had firmly trained his newly gained level of magic, he had successfully made contact with a pack(?) of magical creature snakes that causes Tsunayoshi to twitch in both surprise and alertness.

After all, Mukuro's new partner was a group of Basilisk. The kinds that can cause death just by its song, breath, gaze, and very presence. Although, oddly enough, the snake's gaze has no effects on Tsunayoshi and the two other boys. At all. Much to Mukuro's happiness and satisfaction. Those snakes were forbidden to step into human society and their territory.

Mukuro happily created a Mini-Island using Mist Magic that was bound to his soul and left those little kings if serpents there.

As for Ken and Chikusa, their magic capacity had also increased by a lot too. Not as much as Mukuro but nearly the same amount nonetheless.

Tsunayoshi doesn't know if it was because Chikusa looked up to Mukuro too much or what but his summoned partner was Asian Dragon made from Water. Tsunayoshi doesn't know what this dragon was called but it was able to manipulate both water and weather and had a very high regenerative healing factor. Chikusa called it Cylesta.

As for Ken's summoned partner, it was a Hellhound with three heads and the ability to change its size and form. Tsunayoshi can't decide if that Hellhound was a Cerberus or a Fenrir. Both and either one is bad news to any enemies out there.

Tsunayoshi doesn't know what those fucking damn Estraneo Scientist had done to the three boys for their summoned partners to all have associated with deaths and poison in general. But if Tsunayoshi had ever found out that there are still remnants of those bastards, he was going to use his new powers to send them all to hell with no guilt whatsoever.

Anyway, for Tsunayoshi's partner himself, he now has the ability to summon up to 21 various different kinds of magical creatures. However, he didn't make any contacts with any.

He already has too much shit to worry about. He doesn't need magical creatures mixed into it.

The rest of Tsunayoshi's time was spent tending to the store and its customers, making sure that Byakuran and Reborn didn't kill each other. Helping the three boys train their new magic abilities, trains his own ability, takes care of the farms inside his flame space, donates what he could, collecting information about the Vongola and Mafia in general. Making sure that Nono actually turned out to be a decent father to his four sons.

And making enough wines and Prime Grade beef to 'tame' Xanxus's temper. This part was requested by Mammon.

Tsunayoshi would like to say that life in this parallel world was weird but he had already experienced weirder life so he didn't make much of a sound about it.

It was a month into summer break that Tsunayoshi decided to close down the store and takes the three kids to a summer vacation in Japan. Much to Reborn's irks and irritation since he can't come with them.

From Mountain Fuji to Kinkaku-ji, Fushimi Inari Taisha, Kiyomizu-dera, Senso-Ji, Arashiyama, Osaka Castle, Tokyo Skytree, and even Meiji Jingu. From all sorts of popular and iconic local food and drinks to all sorts of shopping trips.

They spend two months in Japan experiencing all sorts of things. Chikusa found himself liking all sorts of shounen manga while Ken likes Sports manga. Mukuro, however, didn't restrict his reading materials and bought all kinds of manga, books, novels, and who knows what else.

They took pictures, videos, and all sorts of memorable things back to Italy.

Amongst the trip, they all stop by Namimor briefly and meet Hibari Kyoya. Who, in this life was born two years younger than Mukuro.

Their meeting was very... lively. That's for sure. A whole park was gone, three households had completely disappeared. But, luckily, there was no one injured from their fights. In that fight alone, Kyoya had completely awakened to his Cloud Flames, or in this case, Cloud Magic. Kyoya's father, who was Fon's younger brother, had to knock Kyoya out to stop Kyoya from continuing to fight with Mukuro. Tsunayoshi himself didn't stop them since he was busy stopping the spread of destruction from reaching other people in Namimori.

However, since seeing Kyoya was like a punch to Tsunayoshi's guts, they didn't stay in Namimori for much longer. Although, on the way back, Tsunayoshi kept having this odd feeling that he left something behind that he wasn't supposed to. However, after checking all their things and found none missing, Tsunayoshi tried to ignore that feeling. It was slightly hard.

Tsunayoshi just didn't know how or why when they got back to Italy, Kyoya was already there with a metal tonfa in hand ready to continue to fight with Mukuro. His father and mother were beside him, both with resigned looks in their eyes and face.

However, before Mukuro can provoke Hibari Kyoya even more with a word, Tsunayoshi lets loose his flames and turned all the kids and the two other adults completely flame drunk. All four of the kids dazed over nothing and soon enough, Kyoya was found sleeping with his head on his mother's laps while Mukuro and the other two kids were tugging into their own beds.

What happened next, Tsunayoshi didn't know how it was possible.

Let's just say that in the end, it was decided that Kyoya would be living with them.

Since... he accidentally harmonized with Tsunayoshi without knowing it.

Tsunayoshi would also like to say that he didn't even notice that he had harmonized with Kyoya, too. Since... Kyoya's flames were far too weak.

Much to Kyoya's frustration.

Honestly, Tsunayoshi doesn't even know why and how Kyoya was able to harmonize with him. After all, their age difference and mentality were far too different. Their life values were even more different. And yet, this 10 years old kid was still able to harmonize with Tsunayoshi. Which was just odd.

So, Tsunayoshi went and checked deep within his Flames Core and found out that Kyoya had only harmonized with him in the Outer layer. Not an inner or Core layer like his Guardians and Elements.

Which means that Kyoya could harmonize with two Sky. Ahhh, no wonder Tsunayoshi's Kyoya keeps hovering between Dino and himself. That's because while his Kyoya harmonized as a Core member under his sky, Kyoya was also an outer member of Dino-nii's Sky. And since Dino-nii was also an Outer-Harmonized Member of Tsunayoshi, there was no issue with that.

Now, the issue was if this world's Kyoya was going to be the Core Member of Dino-nii or the Tsuna of this world. Since the Tsuna of this world isn't a Sky but rather a Sun.

After explaining the issue to both the Hibari papa and mama, they decided to talk with Kyoya first.

And thus, when summer ended a week later, Kyoya found himself boarding a plane back to Namimori. He has to hunt for a Small Animal with fluffy hair.

Tsunayoshi doesn't know if he should feel sorry for the Tsuna of this world or feel amusement.

He shook his head. Well, Tsuna would find Kyoya's presence to be a good thing in his life sooner or later. So, Tsunayoshi didn't hesitate to say goodbye to the Cloud.
