Prologue

This king was a terrible coward. That thought kept running in Tsuna's head as the weary king in front of him was sputtering God-knows-what. He was tempted to bang his head against the wall if possible, but a comforting hand squeezed his shoulder. He looked up and smiled at Yamamoto who grinned back reassuringly.

" - with us for several years and loyal to the royal family," the king said, his eyes getting wider every second. "Decimo, you must stay by my side. What if those barbaric monsters rampage the walls this very second?"

"This is why you have the Military Police, Your Majesty," Tsuna said tiredly, ignoring the irritated stares from the other men in the room. "The Vongola Corps was an entirely separate unit of its own. We were originally bounded to the Survey Corps but I recall that your supposed great many greats grandfather tied the Vongola to the services of the Royal Family."

Not like the Military Police can even do much, Tsuna thought with light scorn. Not even once have I seen them use a 3-D gear properly.

"Decimo," an official said with a scowl, "you are right in the bond that the Vongola has with His Majesty. However, as long as the Vongola Corps is whole and ongoing, then you have no right to back down. Primo even vowed to never leave His Majesty and the royal family's side."

"That was Primo," Tsuna said, his voice rising slightly. "I am Decimo. Nine generations of terror and grief is still on-going since the establishment of the Vongola. Our mission was to help the people. Do you not think about your people at all, Your Majesty? People are dying right now. Why don't you open your fucking eyes?"

The men in the room gasped, but the king stared at him, a small visible amount of fear swimming in his dull blue eyes. His hands tightened around his armrests. Yamamoto's hand was gone, lying on the handle of his blade.

Tsuna didn't back down. He sat there as calmly and poised as he could, his gaze unwavering.

"How dare you speak to His Majesty like that?" one of the officials hissed.

"To me, he is not the king, but a simpleton who gave up on his people," Tsuna said, standing up. His black hooded cloak swayed slightly. "Now if you excuse me, I have much better things to do."

"Stop," the king said darkly.

Tsuna paused but did not turn around. Yamamoto stuck to his side, his hand hovering over the handle of the door with the other on his blade.

"If you take one step out of this room, then you are no longer under my protection," the king said. Tsuna heard his chair scrape against the floor.

The brunette scoffed. "Protection? What protection? I can take care of myself very well as you can see. Now, please put more of your efforts into training and keeping an eye on the Military Police. They deserve your undivided attention aside from tea, thank you very much."

"Decimo!"

"You insolent brat!"

"Your tongue wishes to be severed, doesn't it?"

Tsuna whipped his blade out of his 3-D gear swiftly and pointed it behind him. The men flinched.

"My blade is swifter than my tongue," he said, his voice devoid of any emotion. "So I warn you to be careful with your words."

He turned his head around to face the king. "From now on, the Vongola Corps are now an independent unit of its own section. No interferences will be made from anyone whether it be the Military Police or the royal family. Our activities and business are our own. This goes for the Varia as well. A single touch or a graze on any of our group will result in immediatE consequences. Negotiations will be made civilly and without conflict unless you want to lose your heads."

Tsuna ignored the stunned silence from the group. "I, Vongola Decimo, hereby terminate the contract with the royal family and the Military Police. I wish you luck, Lennox."

He walked out the door casually with Yamamoto behind him. They both walked dosn the hallways in silence. Tsuna stared straight ahead. With every step, the weight from his shoulders seem to lift slowly.

"That was a close call," Yamamoto said cheerfully with a small strain in his voice. "For a moment, I thought you would explode or something."

Tsuna exhaled deeply. "Well, I almost did. We should go quickly. The others are waiting."

Yamamoto slung an arm around him and held him closely to his side. "You were cool back there, Tsuna. All mighty and all. So where are we going now?"

Tsuna flushed from the contact but didn't comment on it. "We'll have to see, Takeshi."
When they left, a young man ran towards them with a grin until he scowled.

"Why are you holding him like that, you bastard?" he said angrily, shoving his arm in-between them.

Yamamoto laughed. "He's my friend. Why not?"

Tsuna smiled at the other people awaiting by their horses. It was serene despite its ruckus. However, it was normal, perfectly normal. He frowned. He knew that what he did was reckless in the meeting room, but it was for the best. For now, he just wanted to soak in this scene as much as possible.

"Oya, Tsunayoshi," Mukuro said with a sly smile, "what's the matter? Did you end up killing them in the end?"

There was silence as all eyes turned on him. Tsuna forced a smile but it looked more like a grimace.

"I didn't kill them, Mukuro," he said. "From now on, we're an independent group. We function alone. Where is the Varia?"

Everyone looked at him in shock, but he brushed it off as he mounted on his horse.

"Hn, so you do have a backbone, herbivore," Hibari said, pushing off the tree he was leaning on.

"Boss," a soft voice said, "the Varia is in the Trost District."

Tsuna nodded. "Thank you, Chrome."

He gestured his head at the walls ahead. "We're going."

"Juudaime," Gokudera said slowly, "where are we going?"

Tsuna smiled. "The Trost District. It's been a while since we last saw our friends. We might as well join them."

He saw a small flash of bloodlust in Hibari and Mukuro's eyes as they understood the hidden message. He couldn't help but roll his eyes.

The brunette gripped the reins. "Hurry up. We have our duties to fulfill."

He snapped the reins in his hands as his horse galloped along the clean, cobble-stoned streets. Pristine houses passed by in his vision and the sound of nearing hooves reached his ears. People pointed at them on the streets with a puzzled look.

"The Vongola?"

"Where are they going?"

"They never left Wall Sina before."

"Oh, God. What will we do if the Titans attack?"

"I hope they'll come back quickly."

Tsuna pressed his lips into a firm line. The people here were innocent, but he just couldn't stand the corrupted palace and its residents, especially the damn Military Police.

Well, they do say that Wall Sina is the "most holiest and sacred of the walls that will never be breached". Whoever said that should give himself a pat on the back or, maybe, die miserably in a hole.

He sighed softly. Well, fuck. He had to repay a debt either way. He was a man who never backed down on his word. He wondered if the person is even alive. A wry smile spread on his lips. Probably not.

"Juudaime," Gokudera said, riding next to him, "when we reach the Varia, what will we do?"

Tsuna smiled. "We could party all night."

Gokudera looked at him like he grew three heads and Tsuna laughed. "I'm joking. Let's just get there as quickly as possible."

A bad feeling stirred in his stomach and his senses tingled like crazy when his horse took the first step out of the gates.

"Decimo, where are you going?" a soldier shouted from behind.

"Come back!"

Tsuna ignored them and closed his eyes for a moment, letting his senses guide him on the path. I'm sorry.

"Tsuna, it'll be okay," Yamamoto said on the other side of him.

Tsuna nodded with a gentle smile. "I hope so."

Something terrible will probably happen in the Trost District. He knew it. His sensitive intuition never failed him. If only it told him about mankind's future, he would be content. But it didn't.

Life was just fucking unfair, wasn't it?

A/N Another story...I'm sorry. I couldn't resist! I'm a terrible victim to plot bunnies...

There will be changes with the way I want this to go. I have watched the anime and read the manga for Attack on Titan, and I couldn't believe how little crossovers there were for these two animes. Oh, well. I'll try, haha.

The story will officially start with the invasion of Trost and I'm only keeping it close to the anime until the end of the Female Titan Arc. I won't follow with the manga after that part. I apologize if I offend any of you for making this decision. Originality is what I aim for after that.

The Guardians ages are the following:
Tsuna: 20
Yamamoto: 20
Gokudera: 20
Hibari: 22
Mukuro: 22
Ryohei: 24
Chrome: 19
Lambo: 19

The pairings are undecided. It could be AllX27 or something, I don't know. Why don't you guys vote along the way? XD

Yes, Tsuna is different. He can't stay all nice and forgiving forever. He isn't innocent and naive either. This world has no room for that, sorry! ^^ll He's still cute, guys, and will have his moments, so don't worry. Haha.

Hopefully, you enjoyed this so far and will continue to read. ^^

Please leave a review if you can. Thank you for giving this story a chance!

See you in the next chapter.
