Chapter 1: Transmigration

Vongola HQ, Italy, 20XX

Ka-boom!

An explosion occurred, sending the mansion shaking. One brunette lady in her office looked up as the chandelier above her sway back and forth dangerously.

Zzzzt... zzzzzttt...

The light above flickered between dead and alive. Causing the lady to twitched.

"Those trio morons..." She grunted. Another explosion happens, and the mountain of paperwork to fall and scattered on the floor. The finished and unfinished ones were all mixed over, to point even an idiot would instinctively know that separating and categorizing them later will be a nightmare and half. The lady stood up.

"That. Does. IT!" She growled. "Those idiot better have good explanation for it or I swear I will..." leaving the threat hanging, she stomped out from her office to the lab—location where the explosion came from. Some servants and maid and lower ranked personnel bowed down respectfully as she passed them.

The R & D Wing looks like it was ten seconds away from collapsing, and the idiots in charge of place doesn't do it any favor except making it crumbles faster. Uncaring of the state of building, the brunette lady thrown the door open, blew it off the hinges, and stepped in between numerous cables, scattered paper and boxes that were knocked off, and some other thing she intends to grill the responsible about.

Seeing the said responsible idiot, she called out, "Shoichi! Verde! Spanner! What in the almighty name you three were doing?!"

The trio suddenly jolted and turned around to face her. The red haired one immediately keel over with his hands on his stomach as if having an ulcer.

"Ah, Decimo." The green-haired scientist greeted. "What are you doing here?"

"That's my question Verde. What did you three make this time? I can feel the explosion all way to my office!" and her office was like, on opposite wing. "I swear to God, if you didn't satisfy me with your answer then I'll withhold the budget and ban you three from the lab for whole months."

She got triple horrified look.

"You don't dare..."

"I can and I will. Don't test my patience, Spanner. I'm not in the mood today." As if to emphasize it, her palm lit up in brilliant orange. Just like her eyes.

"Alright." The blonde, Spanner, sighed in defeat before went into science mode. "Based from report of Future-That-Never-Was and some accident regarding Ten-Year Bazooka, we have suspicious that, rather than switch to the future, this Bazooka switch people to future version of their parallel self."

It wasn't that unbelievable, since in Future-That-Never-Was, their decimo supposedly is a male and not female. That was one proof that made Vongola R & D thwart Bovino's claim on Time-Travel.

"Yes, and?"

"...the Mare Ring was able to give its bearer ability to see to the parallel world. However, it only work to the bearer, and even then the information dump was too much for the bearer to take, slowly chipping away their sanity until..."

Yeah. No need to finish that thought. Everyone knew what a nut job Byakuran is. He is a total menace and trouble-maker with his callous world. And to think this current Byakuran had gone to Mafia-Special therapist for his issues. Yeah. Mare Ring did good job damaging its bearer, either intended or not.

"And your point is?"

"We want to see if we can combine the Ten Year Bazooka and Mare Ring's essence to create a portal to come into another world." Shoichi wheezes, slowly rose back to his feet. "We currently trying to combine the Physical Transfer of Ten Year Bazooka with parallel-world channel of Mare Ring. So far, we create this." He waves his hand at futuristic-looking portal that won't be out of place in Sci-Fi movie.

...fitting, since it was R & D Department.

One thing, though.

"Is that thing supposed to do that?" Raising an eyebrow, she pointed to the machine. The trio scientist looked at the machine, which seemingly to turn on by itself. Electric cackling start to appears and rainbow-colored light began to dye the hollow center of the machine, swirling not unlike vortex.

"What the hell?!" Verde cursed before ran to computer attached to it. He types something and cursed, again. "Power Level reaches 73%? Shit! The explosion must be short circuited it!" He turned to Spanner and Shoichi. "Turn it off, Manually!"

"What?!" Shoichi shouted. "But the manual button was on the body frame! Reaching it was impossible." He pointed at the machine, which start sucking anything around it.

"WHO THE FUCK PUT THAT THING THERE?! HAVEN'T I SAID TO MAKE THE OFF BUTTON SOMEWHERE OR CREATE A REMOTE CONTROL!"

"Verde!" The lady screamed. "Focus! What should we do now?!"

"We have to cut off the energy input before it reach 100%-and it was 91%! We had less than one minute!"

The lady was shocked, before her body moved by itself.

She lift the two males next to her like cat, and threw them out of door, before throw something at Verde, causing him to fell backwards, hidden behind the large desk and its bulky computer. Just shortly after...

KA-BOOOOOOOOOOOOMMMMM!

Biggest explosion in Vongola Headquarter's history occured. The Research and Developements Wing was totally decimated by it. Luckily, its three current only inhabitant, Spanner, Verde, and Shoichi, were all right if bit disoriented, had gone temporarily mute, and need immediate medical attention due the failing debris.

...and their Mistress, Decimo Vongola, Sawada Tsunami di Vongola, was nowhere in sight. What was left of her was only the Locked Vongola Sky Ring.

Vongola would never recover from the loss.

~X~

"...where... am I...?"

Sawada "Tsuna" Tsunami blearily open her eyes. She was floating in the endless darkness. Unable to move beyond blinking and twitching. It was as if someone had binds her using very tight and secure chain, or dosed her with enough Rain Flame to kill entire horde of elephant. The place was neither cold or warm. In fact, beyond confusion and inability to move freely, she could feel nothing.

"What happened?" She ask herself. "Last thing I remember..." her eyes widened.

Explosion. Loud explosion and lots of pain followed after.

"I am dead." It was not a question, but a statement. "I am dead. That explosion killed me... I don't want to know how Reborn will react." Cringing at what her former mentor-turned-adviser would do once the news reach his ears, Tsuna turned her attention to her surrounding. "If that was true, then shouldn't I went to Vongola Ring? I mean... my time had engraved there."

"Because you are not dead, yet." A gentle voice said.

Tsuna looked up and whoa, she is pretty.

That woman who approached her was a beautiful one. Her beauty was not of western beauty she saw nowadays, but an oriental beauty. A real Chinese beauty. And by she said Chinese, she does not means the Triad's Ladies who she met during party and arrangements with some of Triad fraction Fon recommended. Those beauty who lure men to follow their every word. No. That woman was of an imperial beauty. A Chinese Princess who are beloved by all. Even as she floating closer, she still somehow manage to look graceful.

If she doesn't have Sky Flame, then she must be a fairy! Was what Tsuna thought.

"U-uhm." She tried to fidget, but unable to do so. "Hello. If this is not rude, then may I ask who are you?" She paused before added, "and do you, by any chance, know why I am not dead, and where this is?"

The woman smiled.

"Indeed I do. It seems it will be for the best to start from beginning." The woman said. "My name is Huiwen. Huang Huiwen. I am, you may say, come from different world and different era." She waved her eyes and the blackness changed into some scenery.

Tsuna saw the ancient Chinese era. One that Fon surely would gladly kill just to see it in its real glory. She saw that this world had something called Spirit Beast—which was very similar to Animal Box in her opinion. She watch how Huiwen's world work as the woman herself telling her about the custom here. Due the war that happens in Carta Mainland for hundreds years, Martial Arts reign true. Warrior become much in-demand profession, with only three Profession outclassed it. Summoner who made bond with Spirit Beast. Pharmacist who create elixir, poison and cures. Enchanter who casting spell and create magical item.

Huiwen come from one of Nation in Carta Mainland. She was Princess Royal to Nanyi Country. The Darling of Country. A princess in all, yet somehow she married below her status.

"I, despite obediently married Xiao Yuancheng, does not loves him. Will never. My one and only love, who loves me back, sadly was out of my reach." Huiwen smiled sadly. "However, he gives me a darling child yet..."

"Someone hated you, and once you dead, the hatred shifted to her."

"...correct." Huiwen nodded. "My former Maid, Xuelin, had been poisoned her behind my back. Slowly chipping away her ability to cultivate and weakens her gradually. Shortly before our meeting, she fed her poison in guise of medicine. My poor Yue'er was poisoned to fatally."

Tsuna's breath hitched. She could feel rage start to build up inside of her.

Growing up in toxic environment because of something not her fault, and has a child as her Lightning Guardian, as well knowing Mafia's lack of Children's Right, Tsuna become very protective of children anywhere. She hated child labor, underage prostitution, child murder, and the worst of all, pedophilia. To hear someone kill an innocent child... if she had her way she would charcoaled this Xue until not even dental record could recognize her!

"I'm sorry for your loss." She said regretfully.

Huiwen shook her head. "My Yue'er haven't gone yet." Eh? "Please save her. I know you can."

Eh? But how?

"My Yue'er now was stuck between life and death. She is not life, as she had no will to life after how people treated her behind my back. But she is not quite die either. If you come and take her body, then she may stay alive."

"Whoa whoa whoa... wait a minute, Lady!" Cried Tsuna. "Do you realize what you were saying? You want me to possess your daughter, pose as her! Have you thought to ask her opinion? Surely you could now."

She had bad memories regarding possession. The blame lies on Mukuro and Daemon. Bloody Mist. They must be related by blood.

Huiwen sighed sadly. "I do. Yet Yue'er truly doesn't care anymore. She gives up. She said, as long as whoever took over can grant her maid justice, she does not care who wear her body and name." Ouch. Poor girl. "You are [Harmony] aren't you? If it anyone else, Yue'er will truly gone and only echo of her memories remain. But if it's you, then you and Yue'er can become one."

This woman... she must be really desperate, huh? Mother's love and all's that. She even turn into possession when everything else fails.

"What do you mean by... become one?"

"You and Yue'er will merges into one soul. She will be foundation of your existence, you will become her fuel to stay alive." Sounds... weird... but not the weirdest thing she heard. Vongola breathe in madness after all.

"Say if I agree, what happens later? My time had been engraved into Vongola Sky Ring. If my soul failed to appear during next Inheritance Trial, then question will raised."

She doesn't want Giotto to go all way searching her. That man acted like overprotective father, more than Iemitsu, ironically. And she doesn't want some crazy scientist create device that combines Ten Year Bazooka and Trinisette aspect anymore after the fiasco that kill her.

Huiwen chuckles. "Do you realize those fine gentleman and brave lady are echo?"

Echo? Does that mean—

"Yes. They all have passed away. The one you met, they all echoes the real deal had left behind when they passed away to next great adventure. Nothing more than restless ghost who unable to rest. Even now, your echo already engraved."

It was...

Was...

Ugh,

Tsuna had no idea what to say. So it's either go to Heaven/Hell or reincarnation huh?

"Alright. Looks like I doesn't have any choice." When did she ever had? Her life practically had been mapped for her. Luckily she can turned down any marriage proposal like what Ottavo did during her reign... if her Guardian haven't deal with the idiots yet. "I shall become your daughter."

Huiwen smiled, and Tsuna feel she had made the right answer.

"Thank you."

As the Princess Royal disappeared, Tsuna finally can move her body. Her legs move by themselves, bring her somewhere, but for the first time Tsuna did not care. As long as she could feel all her limbs, she does not mind.

She finally arrived on small, tiny room, with a small, frail and lifeless version of Huiwen sat on a chair. No. This was her daughter. Yue.

Yue looked up with her empty black eyes. "Are you the one?" Tsuna cringes. Even her voice is dead.

Sighing, she approach Yue end kneel before her. Putting on her most reassuring, gentle smile, and burn up her Sky Flame. "That's right." She said. "My name is Tsunami. In my language, it was written for Beautiful Bond." It vexed her greatly that whenever westerner heard her name, what they thought was always the great tidal wave. Sure it sounds similar, but the kanji was totally different! "I heard you cares a lot to your maid and you want justice done for her. May I know her name?"

"...Dongling." Yue whispered. "Her name is Dongling." Her eyes become glassy. She start to sobs. "I... I loves her... she is kind... she deserves better..."

"Ssshhh..." Tsuna rubbed her back. "It's okay. I will help her. No. We will help her. You and I. How does that sounds? Good?"

Yue nodded.

"Please take care of us, Miss Tsunami."

"Definitely."

Smiling, Tsuna hug Yue close to her chest, as their body start to glow within golden light. The light become blindingly bright, their images start to blurred out and now not even a silhouette can be seen. The difference was Tsuna was brilliant shade of gold tinted with vibrant orange, while Yue is pale gold. The two lights danced together before merges into one.

...and shoot out to Yue's native world.

~X~

Black eyes fluttered open. Tsuna groaned as she rose from the bed.

"Ugh... did I spar with Hibari-san and Xanxus in same time...?" She groaned again and forced her body to move. It was then she realize what she wear was no pajama, hospital gown, or any modern clothes, leave alone one that within her fashion taste.

She was wearing a pale blue and white hanfu, the kind she only saw in Drama and Movie with Ancient Chinese setting. And her hand was so frail and pale, it looks like belonged to anemic person.

"How...?"

Then sharp pain assaulted her brain.

The accident. Huiwen. Promise. Reincarnation.

Tsuna gasped for breath, she almost fell down off the bed.

That's right. She remember it all now. She had promised to keep Yue alive, by merging into her. She realize she had extra set of memories, clearly that one belong to the real Yue, who still alive somewhere deep inside of her. Becoming solid foundation and anchor in this new world.

Tsuna closer her eyes and searching through that memories. Want to know what Yue had gone through to make her give up on living.

...and she nearly burned down the whole building.

The name was Beiyue. Huang Beiyue. Daughter of Princess Royal with some unnamed man whom she loved dearly yet unable to have. Despite her status, Beiyue's gentle heart and unwillingness to hurt people make people think of her as a weakling and began to mistreat her whenever Princess Royal was not around. Her maternal family is cold towards her, save for one exception. Her so-called paternal family was even worse.

In Chinese, to Noble family who practice Polygamy, Harem Household is a cutthroat place. Tsuna knew. Due Tsuna's niceness, she was go-to person for therapy and complain among Ladies at high-ranked party, as she would never spill any secret no matter how juicy it was. She had heard way too much Triad Lady, either Legal Wife or Concubine, complained of their life in Harem household. Sabotage or be sabotaged. Use or be used. Family is in name and paper only.

As "Lineal" daughter yet so weak, Beiyue was held in contempt by two Concubines and the Concubine Children. Whenever they had the chance, they would bully Beiyue without any mercy!

Worse still, after Princess Royal's death, she was almost instantly condemned to live in a shack called Flowing Cloud Pavilion due she was said to contacted an incurable illness.

Fucker! That must be a lie! Why that son of a bitch-!

Then the Princess Royal maids left after her mother's death, until only one stayed. Dongling. The Xiao servants saw it as opportunity to join Bullying-Beiyue Campaign, under thought since Beiyue is a weak and laughingstock, nobody will take her seriously even if she complained.

FUUUUUUUUCK!

This has shades of Pre-Reborn! Sure, she hated how that pain in the ass for all grief he had caused her, but their meeting was a pivotal point for her life to become better. To think she finally stopped having nightmare of still living in Namimori, afraid of getting assaulted at any and every turn, only for this!

She had to wonder if Huiwen knew her past and choose her because of this.

"Whatever." She sighed. "No use crying over spilled milk. It's like other Vongola shenanigans. Just accept it with smile. After all..."

She get off from the bed and walk to the window. Looking up to the sky above. Her eyes reflected the sky full of star she could never saw in modern era. So beautiful. She raise her hand as if to grasp the sky.

"My name is Huang Beiyue." She traced the Phoenix constellation that shone bright tonight. How poetic, as Phoenix in western known as Mythical Bird who always reborn from its ashes. "And here, I herebly swear. I will do my best to live this life. Nothing can stop me."

So what if the whole world is her enemy? Sawada Tsunami had fought tooth and nail to reach what she want. Not a Mafia Boss, but a Vigilante Leader. She earn respect from Male-dominating Mafia, make her name after that buffoon Iemitsu trashed it, and proves to the world that she was more than pretty face. That she was as dangerous as her Guardians, if not more.

And as Huang Beiyue, she was not afraid to repeat all that.

"Come and get me, world. Give me your worst. I will not break anymore."

In the year XXXX, Midnight, the Phoenix Constellation shine exceptionally bright at Nanyi Country. The Star experts and scholars all gathered to observe the constellation, and come to one conclusion.

A new era had arrived. One that bring changes, whether people likes it or not.

Very Well, "Huang Beiyue"

You ask for the worst world can give? Then you shall have it. The heavens are looking at you. Let us see if you can back up your words, shall we?
