-3rd Person's POV-

In a dark office room sat a man in his 20s that have brown hair and gravity defying hairstyle, dull sunset- orange eyes that red through his paperworks.

Not long after, a knock was heard and after the brunette said "Come in" a butler came in.

"What is it Alehandro?" The brunette asked, not even looking up from his paperwork that seemed to have decreased in numbers.

"Tsuna-sama, please eat. You shouldn't starve yourself or they'll be worried if they're still here" the butler said.

The brunette looked up with dull eyes as he stared at his butler "But they're not here, they're already dead you know" he said in a flat tone.

The butler sighed lightly "Please move on Tsuna-sama, they're already dead so please don't torture yourself anymore"

The Vongola Decimo glared at the butler before saying "Get out!" in a sickly calm voice.

The butler bowed and left not before saying "Please take care of yourself Tsuna-sama, they wouldn't want you to be like this"

After the door closed, Tsuna took of his glasses and leaned back on his chair before pinching the bridge of his nose.

"How can I move on if the most precious people to me died one by one and I'm always a second too late to save them?" then he laughed bitterly as tears started to stream out of his eyes.

"First Mama then Dad, next was Hayato then Takeshi, Lambo then Onii-san, after them was Mukuro and Chrome, Kyoya and lastly is Reborn" he said while covering his eyes as tears continued to fall.

A sad atmosphere engulfed the dark office as the Decimo continued to cry until he fell asleep on his chair, a tired and broken look plastered on his face.

It's been about 2 months since his family are killed by an enemy famiglia.

Reborn is the hardest for them to kill, of course he's the number 1 hitman for a reason right?

But they fired him a bullet that will seal his flame for about 10 minutes, that's all what it takes for them to overpower him using their numbers, although Reborn did a number on them too.

Back to the present time, the alarms blazed as a man in suit barged in Tsuna's office and said with a hurried tone "Tsuna-sama were under attack"

Tsuna stood up and wore his gloves, entering in HDWM, his sunset colored eyes shone more brighter as a bright orange flame flickered to life on his forehead.

He walked out of his office in a calm but hurried gaze as he practically speed walked towards the front of the Vongola mansion.

When he got there, he saw 300 or so men, the leader standing at the front with a sick smirk on his face.

"Fufufu~ if it isn't the Vongola Decimo, how is life when your loved ones are killed? Is it hard?" He said with a creepy laugh.

Tsuna felt irritated, no one I mean NO ONE have the privilege to laugh like that in front of him except for his mischievous mist.

Tsuna narrowed his eyes as he said in a cold tone "Who in the f*cking h*ll are you?"

"Oho~ feisty aren't you? Oh well~ My name is Crisando di Calavone, Boss of the famiglia that'll kill you! Hahaha" he said with a hysterical laugh at the end.

Tsuna raised an eyebrow, clearly unamused but angry because now he's facing the famiglia that caused his family's death so he'll definitely enjoy beating them up to the point that they're almost dead.

"Really? Then I'll see you try because you will clearly regret everything that you've done"

The Vongola men stood behind their Decimo.

There's a moment of silence before the enemy famiglia engaged the fight.

Tsuna uses his flame guns as he shot his enemy's down by shooting at their legs and fighting them in hand to hand combat if they get too close.

-Time Skip-

Six hours of non-stop fighting and the fight finally ended, the Vongola coming out victoriously but not with the cost of the many, their decimo included.

Many of their enemies and allies alike mourned for the death of the brightest and warmest sky they'd ever encounter.

At that moment, the Vongola Neo Primo; Sawada Tsunayoshi or Tsunayoshi do Vongola was no more.

And also at that moment, in a parallel world full of heroes and villains awoke a man with gravity-defying hairstyle and amber eyes. The quirkless hero called Cielo.
