soul bonding isn't really romantic. even if the name suggests so. if it seems romantic for you, then you might have read too much soulmate au fanfics, like me. also, natsu's blond part of his hair is the same shade of giotto's hair. personalities are hard idk if a character is ooc or not lmao.

--Duplicated--

"Okay, so first. Congrats, you have successfully Soul Bonded. Your partner is me." Natsu starts off.

"Eh? Soul Bonded?" Tsuna asks.

"Yep, that's what happened. Here's what I think happened. It was most likely a failed assassination attempt. Seeing as I saw some guy with a gun that was aimed at you. The bullet was probably something to make Soul Bonding faster because it is a very long process. We probably were Soul Bonded as I was the nearest Supernatural Being to you."

"Supernatural Being..?" asks Tsuna, in which Natsu justs nods. "I'll get on to that later."

"Soul Bonding is a process of where two beings would bond their souls. In other words, a part of my soul is with you and vice versa. And with that, a side effect would be sharing similarities, like how I got your appearance. Though, I'm not really sure if you'll be getting anything from me. I'm guessing that the bullet was never been tested and has a chance of being a failed experiment. Soul Bonding used to be very well-known but it is rarely done nowadays.

It usually has one human and one Supernatural Being. It is advisable for it to stay like that. As for a Supernatural Being to bond with another, it would tire both parties mentally and physically. Each time they use their Supernatural properties like their powers, it would tire both of them. It is also not advisable to have a human to Soul Bond with one another human as it would hurt them for reasons unknown."

"You got all of that?" Natsu asks the other boy. "Y-yeah... I think so." Tsuna says, processing the information dump.

"You're a Supernatural Being, right? So what are you?" asks Tsuna.

"Ah, right. I have no problem showing you." Natsu says. Then, a wing withdraws from Natsu's left side. It was big and its color was dull, a bit gray instead of the pure white color of the wings of Angels.

"O-one wing?" Natsu smiles at Tsuna's confusion, "Yeah, but I won't tell you the reason, though."

"I'll explain what I am. I am an Angel...kind of. Power is everything in the Supernatural community. There is a category in the community, the Liberos Metit*. Basically those who had died as human before.

In the Liberos Metit, there are the Demons, Fallen Angels, Angels and Rising Demons. The most powerful out of the four are the Angels, followed by the Demons, then the Rising Demons and the weakest out of the four, Fallen Angels.

I think you know what Angels and Demons are, right? They are pretty popular, I heard."

Tsuna nods at Natsu's question. Natsu then resumes to his explainations.

"Rising Demons are Demons who used to be bad, but for whatever reason, became good. Though, I heard that there are some who were always Rising Demons ever since they died.

Fallen Angels are the opposite of Rising Demons, Angels who were good, but got tainted. Like Rising Demons, there were some who were always Fallen Angels from the start.

I fall somewhere in the category of Angels or Fallen Angels."

"Eh? Don't you know whether if you're an Angel or a Fallen Angel?"

"I mean, ever since I died my wings were always like this shade. It wasn't pure white like the Angels but they weren't pitch black like the Fallen Angels." explained Natsu with a shrug.

"Ah, quick question. Are you in the Mafia of perhaps know someone in the Mafia?" Natsu asks out of the blue.

"Eh?"

"Sorry, it's just that you look like someone well-known in the Mafia."

"Uhm, yeah I am in it. I'm guessing that you are also in it, right?" Tsuna asks. 'And just as I thought I met someone normal! Most of the people I know are in the Mafia!'

"Nice. If you don't mind me asking, are you a hitman, then?" Natsu asks.

"No... I will be a Mafia boss." '-of the biggest Famiglia! I never wanted to be one!' Tsuna shrieks in his mind.

"Eh, I don't think anyone want to be in the Mafia. And if they do, then they might be some weird fangirl or something." Natsu says with a nonchalant shrug.

Natsu sees Tsuna's confused face, "Ehh?! Mind-reading actually exists?! Does that mean Reborn can actually read minds?!"

'The World's Greatest Hitman is here? He did say that he 'will' be a Mafia boss, then the Sun Arcobaleno must be here to train him. I heard that he did train Cavallone's tenth boss.'

"Eh..? Oh, no. It's just your thought was noisy to the point I could hear it. It's because of the Soul Bond. Most of your thoughts will not be heard, don't worry. But, if it's noisy enough, I could hear it and vice versa. Basically, we can communicate telepathically by shouting in our minds or something."

"Oh..Ah! How will I explain this to Reborn?! How can I even explain it to Okaa-san?!" Tsuna panics. His panicking stops when Natsu placed a hand on his shoulder.

"It's okay, I got a great idea." Natsu assures the other, having his wing hidden.

Tsuna's worried face changed into a hopeful one, "Really? What is it, then?"

"Don't. I'll hide. And you don't have to worry." Natsu says with his other hand forming a thumbs-up.

Tsuna sweatdrops, "Eh? That's the best idea you have?!"

"Hey, you don't have a better one. Besides, even if Reborn is The World's Greatest Hitman, he is still human. I don't think he can beat the Supernatural. There may be a book or so in the Library that can help me conceal my presence from others except you." Natsu explains, in which Tsuna nods to.

"Anyways, can I stay here, Primo-san?" Natsu says.

"Primo-san...? Uh, sure. You can stay here." Tsuna says, already accepting his new nickname as he is already used to it.

Tsuna sighs, another weirdo who's in the Mafia barged into his life once again. Then again, should he be suprised at this point.

Liberos Metit - translates into 'Reaper's children in Latin, or so I think.

Namimori Rumors!

I heard that in Natsu's past life, his eyes weren't gray. Some even said that he had heterochromia! I wonder what color his eyes were...
