Ganauche gritted his teeth and stomped towards Iemitsu before grabbing him by the collar, "THE FUCK, IEMITSU!! NO MATTER HOW MUCH YOU HURT OR REJECT CIEL, IT DOES NOT CHANGE THE FACT THAT HE IS YOUR SON!!!"

Understanding what was just said, Tsuna dropped the thing he was going to throw at Iemitsu next.

"W-What?" He stuttered in disbelief.
____________________________________________________________

Tsuna couldn't believe what he just heard. His HI confirmed that what Ganauche has just said is true, he observed the younger boy's appearance, Ciel has cream colored hair and amethyst eyes. He looked a bit like Iemitsu. He then looked at his mother's features, Nana looked confused but showed no recognition that he knew Ciel.

Everything clicked in place, Tsuna's eyes widen, 'N-No w-way......'

He was snapped out of his thoughts by Iemitsu and Ganauche's argument.

"SHUT UP GANAUCHE!!! AS I SAID, IT IS NONE OF YOUR BUSINESS SO WHY DO YOU CARE SO MUCH ABOUT THAT BASTARD CHILD!!!"

"SHIT, IEMITSU!!! CIEL IS MY CHARGE EVER SINCE HIS SORRY EXCUSE OF A MOTHER TRIED TO KILL HIM!! ANYTHING RELATED TO CIEL IS MY BUSINESS!"

Coyote walked up to them and pushed them apart, "Calm down you two!! There are children here for hell's sake!!"

'Where's Schnitten when you needed him?! Making peace is suppose to be HIS job!!" he thought.

Inside the Vongola HQ, a certain rain guardian sneezed.

"Are you alright, Schnitten?" Brow Nie Jr. (Nono's sun guardian) asked.

"I-I'm fine"
____________________________________________________________

"YOU STAY OUT OF THIS COYOTE!!" Iemitsu yelled at the storm guardian.

"Iemitsu, will you please shut up!!! Ciel is your son wether you like it or not!!" Lal yelled.

Ciel was by now crying as Nana tried her hardest to soothe him, she didn't understand what they are talking about since they're not speaking Japanese but Ciel clearly understood it all.

Takeshi also didn't understand for the same reason as Nana but he somehow knew that this is all about the boy his surrogate mother is currently soothing.

Iemitsu clenched his fist as he glared at Lal, "THAT BASTARD IS NOT MY SON AND NEVER WILL I ACCEPT HIM!! I DON'T EVEN CARE IF HE DIES!!!"

That did it, Tsuna snapped. Sky Flames blazed wildly on his forehead and now gloved hands as he punched Iemitsu on the face. Them finding out he has sky flames be damned. He does not care anymore. Iemitsu crossed the line when he said that.

Nana screamed as Iemitsu collided on the wall creating a large dent. She fainted while still embracing Ciel.

Ganauche, Coyote, Lal, and Takeshi stood there, dumbfounded at the same time shocked. The two tied up men fainted from getting hit on the head by something that fell on them.

Tsuna looked at Iemitsu's form, his sunset eyes blazing in fury. "How. Dare. You" he growled.

In a blink of an eye, he was in front of Iemitsu, like Ganauche, he grabbed Iemitsu by the collar, "How. Dare. You. Say. That".

Memories of his talk with Hayato flooded Tsuna's mind,

:::Flashback:::

[[[Tsuna's original dimension, ((Vongola Headquarters))]]]

"Hayato..." A 20 year old Tsuna called.

Hayato who was busy sorting out his boss's paperworks turned to look at him, "Hai? Jyuudaime?"

"Before you met me.....What was your life like?" Tsuna asked. Tsuna mentally slapped himself for asking that, I mean, how could he?

Hayato froze at that question, he was silent for a few minutes, making Tsuna worried, he was about to tell Hayato that it's fine if he didn't tell him but Hayato looked at him, his eyes filled with both sadness and determination, "As you know, Jyuudaime, I am a child of my father and his mistress, a bastard child to be exact." he began.

Tsuna wanted to protest at what he called himself but was cut off by Hayato.

"I was taken from my mother when I was a baby, raised by the Gokudera Family. Even though I was treated like a prince, people and servants still talked behind my back, saying that I am of no importance, that I don't deserve to be treated like royalty, because I am the son of the mistress. That's also the time I found out who my real mother is"

Hayato let out a pained laugh,

"Imagine, the piano teacher you look up to as your surrogate mother is in fact your real mother, haha, I was living in the world of lies"

"Hayato, that's enoug-"

"No, Jyuudaime.....you need to hear this"

Tsuna looked at him before reluctantly nodding.

"I ran away from the mansion, Shamal took me in.... As I grew up, I became interested in explosives, that's where I got the name, Smoking Bomb Hayato....After a few more years, Reborn-san called me to test you and you know the rest" Hayato finished.

Tsuna couldn't help but frown, "Weren't you lonely?"

Hayato looked surprised before a genuine smile appeared on his face,

"Even if the servants in the mansion are talking behind my back, the care and love my sister and father gave me are genuine so no, I was not lonely, but when I met you, I experienced having real friends, People who accepted me for who I am......A real family."

Tsuna smiled brightly at that, "Hayato, remember this, we are there for each other, we defend each other, and we care for each other, even if two certain people won't admit it" Tsuna said as Kyoya and Mukuro appeared in his mind.

"Hai, Jyuudaime, I'll remember that. Now, let's get back to your paperworks" Hayato declared, holding up a stack of papers he finished sorting out for his boss.

Tsuna groaned and slammed his head on his desk.

:::End of Flashback:::

'Hayato has his sister and father, Ciel grew up being rejected even by his real family'

Tsuna's eyes glowed, "DO YOU KNOW HOW HE MUST FEEL RIGHT NOW?!" Tsuna yelled.

"HIS DAMN STUPID FATHER SAYING THAT HE DOES NOT FUCKING CARE EVEN IF HIS OWN SON DIES?! DO YOU FUCKING KNOW WHAT YOU ARE SAYING?! HELL, YOU SAID IT IN FRONT HIM, ARE YOU REALLY AN IDIOT OR ARE YOU JUST FUCKING INSANE?!"

Takeshi gaped at his best friend's very colorful language, Tsuna does not cuss, wait...scratch that, he never cussed nor does he raise his voice this high. Actually, this is the first time Takeshi had seen him this furious......no.....this is the first time he had seen him so enraged.

"Tsuna...you don't understand!! He's not from your mother but someone elses!!" Iemitsu weakly yelled, he really hit that wall....hard......he  too is shocked at the flame that his son produced and the strength he used to throw him, but judging on the situation right now, it's completely irrelevant to the subject.

Tsuna clenched his teeth, "Wether he is the son of a mistress or he is from my birth mother, the fact that he has your blood still makes him my brother, even if I hate to admit that you are my birth father!!" He hissed.

Coyote and Lal couldn't helped but be impressed, "If he was chosen as the Vongola's heir, then I would believe that Vongola can return to its original purpose" Coyote stated.

Lal looked at Coyote, "So do I, too bad Nono does not see that the current heir will only bring Vongola's downfall" she said, Ganauche nodded at that, agreeing with the both of them.

If only Nono can see through that fake kindness of his so called heir, If only he can see that darkness and greed Iekatsu has. If only he can see that he is not the right choice to become the Vongola's heir.

Coyote looked at Tsuna with respect.

If it is only him.....

The boy who looked exactly like Primo.

The boy who produced the purest sky flames he had ever seen or felt, purer than Nono or even the Primo's sky flames.

The boy who defends his family so fiercely.

The boy who has the qualities of a true boss.

And the boy who deserves to be the Vongola Decimo.
