"Doesn't the idiot have an older son?"

"Yes... But I have made him the heir to CEDEF instead of Vongola."

"It's usually the older child who inherits, you know?"

"I know. Just this once, I will curve away from traditions."

"You want me to teach a civilian child how to be a mafia heir..."

"It might sound troublesome and impossible but I hope you might consider accepting; especially since you owe me a favour, old friend."

"Resorting to threats now, Nono?"

"I am not threatening you. I am just merely reminding you of it's existence, my friend."

"Fine."

"Thank you, old friend."

"Don't thank me. I'm just doing this because I owe you a favour."

"I know."

"Are you seriously fucking kidding me?!"

"Giotto, son—"

"No! You promised! You fucking promised!"

"Please just listen to me—!"

"No! You told me you'll leave my brother alone if I came with you!"

"I know! But you also know that I'm not the one with the power to decide!"

"You have the power as a father, you asshole! You don't have to be the fucking Don to do your duty you so 'proudly' babble to anyone within earshot!"

"I tried!"

"You didn't try enough, Iemitsu."

"Why do you even want the civilian child? I heard the oldest son is quite the charmer and, not to mention, a genius."

"Giotto is indeed a genius and charming man. He is also quite proficient in traversing the mafia world."

"So why the civilian? This 'Giotto' is surely the perfect candidate to take over the throne."

"He is perfect..."

"I sense a 'but'."

"But he is not malleable."

"I see..."

"Don't just decide in a blink of an eye, you fucking idiot!"

"I just can't let them sink their claws on my brother! I bathed myself in blood when they said they'd take me instead of my little brother!"

"Please think about this thoroughly, Giotto. G is right that you can't just dive into this without proper plans."

"They are right, Giotto. You wouldn't be able to protect your brother if you got your self killed before you even can see him."

"Let me come with you."

"And why should I?"

"He is my brother."

"You think I care about that?"

"No. But you need me if you really want my civilian brother to be the heir to the bloodiest Family."

"I don't need your help. I am the World's Greatest Hitman."

"Yes, Hitman, not tutor or teacher."

"I could just kill you for your insolent mouth right now."

"You can, but you won't. Even you wouldn't want to face the wrath of Vongola alone."

"He just accepted?!"

"Yes."

"Are you fucking serious?!"

"Yes."

"Nufufufu... I'm surprised he didn't kill you with your demand to join him."

"He threatened me, yes, but I said that even being the World's Greatest Hitman he wouldn't be able to escape the clutches of Vongola."

"Shit. You just threatened the strongest Arcobaleno, Gio."

"My guardians will come with me."

"I don't care, as long as you don't mess up my mission."

"I want you to gather everything I need to know about Sawada Tsunayoshi."

A/N:

Hi! This just came to me when I was in the middle of binge watching some of my favourite childhood animes. This will be a short story, so expect this to be at least 2-5(?) chapters only.
