Mini Primo, or else known as Sawada Tsunayoshi is the younger brother of the infamous Vongola family first boss, Sawada Giotto Ieyasu. He is 10 years old and has a brown gravity defying hair, very much similar to his brother's and has a pair of big doe-like soft brown eyes. He lives in the Vongola mansion with his uncles' brothers which are his own guardians.

He is staged to be the second boss of the Vongola property and is to lead the vongola after his brother's retirement, which is, well, still a bit of time to take or so they thought. Despite his young age, he is quite clever and loves everyone in the mansion. He took up his flame power from his brother who has the same element: sky, which engulfs and colors everything. He'll also inherit his brother's demon tutor, Reborn when he reached a suitable age to start his training.

And he is now searching for someone. Someone he loves and someone he cares about. He has been searching for this person throughout the mansion and not find a single trace about this person he is searching. Then, he starts asking other people about it.

"Hayato-kun, did you see Gio-nii? I can't find him.. *pouts*" asked Tsuna.

"No, Tsuna-sama. I didn't. May I ask why did you want to see him?"

"Well, everyone is here today, so I thought I wanna play with everyone today. But, I don't see him everywhere."

"How about his office?"

"It's locked."

Both children looked a bit disappointed, especially the silver haired one. Gokudera Hayato has always been fond of Tsuna because of his kind traits. He respects and treats him differently from others. Hayato has silver hair, quite different from his brother which is red but has the same hairstyle. He has emerald green eyes and carries dynamites all the time, which, of course pissed off the readhead.

"He's in his office, you know. Brother said he is locked inside until he finished his paperwork."

Answering their questions was a boy around their age which has black spiky hair and caramel brown eyes, Yamamoto Takeshi. He is the brother of Yamamoto Ugetsu, owner of Shigure Souen Ryu which is, of course has been passed on to his brother.

"Baseball-freak! What do you mean by that?!"

"Maa maa. Calm down. Like I said he is locked inside his office until he finished his paperwork. You don't have to worry about it"

"Ehh!? Really?" said the brunette.

"Yep! So what are playing today?"

"Baseball-freak! Don't be rude to Tsuna-sama!"

"It's okay, Hayato-kun. Besides, we should all play together today."

"If that's what Tsuna-sama wants, then.."

The trio quickly find the others and asked them if they want to play together. Unexpectedly, even the young skylark agreed to play with them. Maybe because of the boring atmosphere.

As expected, the game they are playing almost burnt off 1/5 of the mansion, which enraged the head of the mansion, Giotto.

"What the heck just happened here?!"

"Ah, Giotto-nii.. We're playing hide and seek. You want to join?"

"Tsuna…. I believe in you… (starts crying) and you did this to me? (being emo)"

"Ehh? Giotto-nii?"

"What's happening? Giotto? Tsuna?" asked G who just arrive to the scene.

"G, I entrust you to look after the kids when I'm doing my paperworks. That's why I let you to lock me in. and what did you do?" asked the blonde while compressing his rage.

"Well, I have my own work to attend too, you know." G said with a straight face.

"…"

"Primo?"

"I'm giving you all the paperwork."

"What!? You can't just let me do that!"

"Of course I can. I'm the boss after all."

"Giotto, you little-"

"Giotto-nii, you okay?" asked the brunette.

"Yes, I'm fine, Tsuna. Why did you ask?"

"No, you seem to be in pain for a moment there. I guess it's my imagination."

As sharp as always, my little Tsuna "Nah, I'm okay. I'm just pained to see how much my paperwork will increase because of these."

"Oh. Sorry. We'll stop."

"Thanks, Tsuna. Look, my brother beat you, G."

"Yeah, right." G replied with a scowl.

Because of the pleading of his beloved brother, Tsuna has stopped the game they were playing and started to discuss about another safe game to play.

"So, what should we play now? I mean another safe game to play. Anyone has an idea?" asked the brunette

"Mmm.. how about baseball?" replied Takeshi.

"Baseball-freak! Don't drag Tsuna-sama to your stupid game!" yelled Hayato.

"Other?"
