"Oh no…What should I do?" Tsuna muttered to himself. By Reborn saying this afternoon, it would mean in half an hour's time! He will have to warn his guardians, before they killed the new tutor if he was indeed—by some rare luck—a stranger.

With that in mind, the young boss-to-be ran out of his office in search of his guardians.

He didn't run far before he crashed head-first into his carefree Rain Guardian.

"Ita ta ta ta ta…" Tsuna mumbled while rubbing his sore head. Yamamoto definitely had a hard head!

"Ah! Tsuna! My bad, didn't see you coming! Are you alright?" Yamamoto laughed sheepishly as he helped his friend up to his feet.

The carefree teen had a set of casual T-shirt and long-pants combination on. Resting on his chest was a necklace in the shape of a miniature sword and the Vongola Tenth Generation crest on it. Despite its complicated designs, it seems to fit into Yamamoto's casual attire like it belonged there, not at all out of place.

"Yeah, I'm fine, thanks, Yamamoto!" Tsuna said, still nursing his head. "By the way, do you know where the rest of the Guardians are? I have an urgent announcement to make to everyone."

Yamamoto scratched the back of his head in a thoughtful manner.

"Eto…not really, but I just past by the kitchen and it seems pretty noisy in there. So I'm guessing they are probably in there. Ah! Kyoko and Haru told me to tell you that they went out to buy some ingredients with Bianchi."

Tsuna nodded and shuddered at the thought of more dishes in Bianchi's menu. Instead, he focused on finding his Guardians.

They had just managed to get Mukuro out of the Vendice prison through some negotiating with the help of the Ninth, under a few conditions—of course—such as the current boss of Rokudo Mukuro has to take responsibility of his actions, if any.

As for what kind of punishment Tsuna has to take for Mukuro, let's just say that Tsuna would never want to think about it ever again.

Ever since Mukuro was back, the already-not-peaceful mafia days of Sawada Tsunayoshi has gone from bad to worse than living hell. The whole of Mukuro's Kokuyo gang—meaning Ken and Chikusa—has decided to move in to the Vongola mansion since their leader didn't want to 'leave his precious Chrome alone in the hands of the hungry mafia'.

Hibari and Mukuro just can't have a peaceful conversation in each other's presence. With a 'Kufufufu' and a 'Kamikorose' following shortly after, all the rest of the Vongola mansion residents could do was to find a safe place to take refuge in.

This has caused the Vongola mansion three repair works in the one year that they had spent in it.

The funny part was, the Ninth just chuckled and said merrily something along the lines of "Teenage is indeed the time when one is most lively, isn't it? Such energy! If only I could move like that once again!"

Tsuna sighed and shook his head. He could never fully understand what's going on in that quirky old man's head.

When they neared the kitchen, Tsuna knew for sure that they had come to the right place. Yamamoto chuckled when the distinct voice of Gokudera thundered, "*AHOSHI! SHIBAFU ATAMA!"

Approaching the door to the kitchen, the roaring of voices got louder and Tsuna was sure that he heard the sound of tonfas clinking together. Tsuna cast one nervous look at the black-haired teen behind him—who chuckled nervously back—gulped, and opened the door slowly with shaking hands.

He had to duck just in time to avoid the frying pan that flew through where his head was just a milli-second ago.

Sometimes, his Super Intuition really comes in handy to stop his head from saying a permanent goodbye to the rest of his body.

Well, at least his entrance had caused a temporary heartbeat of silence; and not a very long heartbeat at that. They all took in Tsuna's formal attire before going back to whatever they were doing before they started the fight.

They all knew that the suit meant that their young boss had just come back from an important event. Usually, that would mean that Tsuna has yet to revert back from his 'Boss Mode'—who could be very scary when unable to tolerate their bickering.

Well, all went back to their things except for a certain silver-haired Italian.

"JYUUDAIME!" Gokudera nearly screeched. Immediately, he threw himself down in front of Tsuna, repeatedly banging his head painfully on the ground. "I didn't stop that frying pan in time! I am not fit to be your right-hand man!" Gokudera yelled as he continued his self-punishment.

"Ah, Gokudera-kun! There's no need to go that far!" Tsuna tried to reassure the silver-haired teen. He tried—in vain—to drag the other teen off his knees. "As you can see, Gokudera-kun, I'm perfectly fine!"

"If Jyuudaime says so…" Gokudera hesitated, then mumbled reluctantly.

He smoothed his white top, straightened the red shirt that he wore over it and looked down on the ground, twirling his fingers and looking very guilty. The leopard-patterned buckle with the Tenth Vongola Generation crest on his belt informed everyone who saw it that he was Hurricane Bomb Hayato, Vongola Storm Guardian.

The ever-bloodthirsty Hibari gave an uninterested 'Che'—identified by his bracelet with a porcupine design and the Tenth Generation Vongola crest as the Vongola Cloud Guardian—and headed out the door. The glinting tip of his tonfa peeked out of the Namimori school jacket that the devoted prefect still wore on his shoulders dutifully.

However, before Hibari could fully exit the kitchen doors, Tsuna's hand caught his arm.

"…Have you finally decided to fight me, herbivore?" Hibari's voice cold and emotionless, but anyone could hear the bloodlust concealed just beneath the surface.

"No," Tsuna smiled. It was an innocent smile that was supposed to be extinct on any mafia boss' book of 'My Facial Expressions'. "I have something to tell all of you. So, please, Hibari-san." Tsuna gestured to inside the kitchens.

Hibari didn't look very happy. Tsuna could feel Gokudera and Yamamoto shiver involuntarily under the Cloud Guardian's cold glare. Tsuna smiled apologetically at Hibari, he knew how much Hibari hated being with a crowd.

With a huff, Hibari settled in a shadowed corner of the kitchen, away from everyone else.

"Oya, oya… It seems like Vongola does have something really important to say." Mukuro chuckled. His forever unreadable heterochromatic eyes were fixed on Tsuna's face, the Vongola Mist Earring hung—glittering proudly—on his ear. His violet ponytail was slowly growing out, but how he still managed to keep that pineapple hairstyle without any help from accessories was something no one could understand.

Chrome looked up from the pineapple tarts that she was making with Mukuro—she did not throw Mukuro into the mixture—and focused on Tsuna too.

"Boss…" she said softly.

Ryohei stopped his 'EXTREME!' yelling—and boxing—contest with Ken the moment he heard Tsuna's words. He may not be the brightest among the Guardians, but the Sun Guardian knew when to listen and when to continue on with his extreme ways.

Ken wasn't exactly excited about whatever Tsuna was going to say, but seeing Mukuro and Chikusa paying attention to the young Vongola boss-to-be, he grudgingly did so too.

The six-years-old Lambo was the only one who wasn't quiet. I-Pin chided him on giving Tsuna some respect; the words seem to have some difficulty reaching his ears through the thick afro Lambo sprouted.

"Dame-Tsuna! Give the great Lambo-san many, many candies!" Lambo ordered while clinging onto Tsuna's leg.

Though a year had passed, Lambo did not mature a teeny bit at all.

Tsuna just stared at the boy patiently, waiting for him to realize on his own that it's not the time to be annoying.

"How dare you say such rude things to Jyuudaime!" Gokudera yelled at the little cow. "Get off Jyuudaime right now or I'll blow you up!" Several sticks of dynamite made their grand appearance.

"Don't wanna, Aho-dera! Go away!" Lambo yelled back. I-Pin tried again, "Lambo, **ting xià!" Tsuna doubted Lambo understood the Chinese part.

Well, the damage is done.

Gokudera gave a wordless roar and blew the spoilt child to the other end of the kitchen.

"Ga..ma..n…" Lambo burst into noisy tears.

"Enough, Gokudera-kun." Tsuna finally cut in. Hearing Tsuna officially enter his 'Boss Mode', Gokudera immediately bowed deeply, not daring to utter even an apology.

"Alright," Tsuna begin, when he finally got the attention of everyone. "I was going to tell you guys that Reborn is leaving for a long-term mission. Thought that is a good news, but he seems to have arranged for a Substitute Tutor to take his place while he is gone. This Substitute Tutor will also take over our training-monitoring, so please don't be surprised if he oversees your personal trainings."

The Guardian's various reactions to this revelation were of varying degrees of surprise. Needless to say, Mukuro, Hibari and Chrome were at the rock-bottom.

"Kufufufu…interesting. I wonder who this person would be." Mukuro leaned on his trident. Chrome just went back to her pineapple tarts.

It doesn't matter to her if there's another extra face wondering around the mansion. As long as her Mukuro-sama is with her, she can face anything.

"Is he strong?" was Hibari's only concern.

"I'll get him to join my boxing club to the EXTREME!" Ryohei punched the air enthusiastically.

"LAMBO-SAN WANTS CANDY!" Lambo wailed from his corner.

"Haha! The more the merrier, right?" Yamamoto laughed, and for him, everything was settled in that one laugh.

"Jyuudaime doesn't need anyone to tutor him! Jyuudaime can handle his studies and training by himself! What was Reborn-san thinking?" Gokudera's reaction was by far the most animated. He just can't get over the idea of Tsuna being the only being in the universe.

"Gokudera-kun, it is fine what Reborn had arranged. I do need a bit more advice on training and studies." Tsuna smiled that innocent smile once again. Gokudera blinked and looked down; twirling his thumbs again, a faint pink tainting his cheeks. "If Jyuudaime says so…"

"Maa, maa. When will this Substitute Tutor arrive, Tsuna?" Yamamoto asked.

Tsuna looked at his Rolex, "Right about—"

He was cut off by a servant's knock on the open door of the kitchen. All eyes were turned towards the now-slightly-uncomfortable servant. He bowed deeply.

"Lord Sawada, there's someone at the door who says that you are expecting him and claims to be the new Home Tutor."

Nine pairs of eyes were now trained on the young Vongola boss. Tsuna sighed and straightened his black tie.

"Bring him in."
