Hello! How have you been? It's been a while since the last story, but now it's finally time.

This is by far the greatest adventure I've ever written.

If you're a new reader, please heed this warning: Please consider reading my previous stories, this is a saga of adventures that began more than three years ago and will be diving into several spoilers of Mario, Hetalia, Total Drama, Danganronpa, OK K.O. and All Saints Street in terms of canon and this saga.

If you've read my previous stories: I really hope you enjoy this new adventure.

Mario X Total HetaRonpa Street begins now!

Prologue Part 1: Dimensional merging! Summon all heroes!

UN Base, New York.

For what it was supposed to be a peaceful discussion, things surely went downhill so quickly. "How in the hell you let that crook convince us?!" yelled England to the other nation he's currently shaking. "Please, calm down. There's no need to get physical" Japan tries to end the conflict.

"I hate to break it to you, England, but this time it's not my fault. I'm not Canada!" America smugly parries.

"Esta vez you were wrong England, this show es de Canadá." Mexico says, amused by the altercation. "England, Total Drama is produced in my country." Canada softly remarks. The gentleman quickly recognizes his mistake and lets go of America while Russia chuckles, "You have to admit that the flush of shame sounds a bit funny".

"Only you are capable of mistaking America for Canada and vice versa. That is truly pitiful, huh England?" France mocks him, making the british to lunge at him and start yet another fist fight.

It has been one year and three months since the 78th Class arrived on this Earth and ten months since Trevor's arrival. Ever since then, they and the two generations of Total Drama have been tirelessly defending this world. As for the Nations, they've been mentoring them and easing their stress from this lifestyle.

But now things have gone into madness since Chris Mclean, the host for Total Drama got out of jail for contaminating Camp Wawanakwa on the last season of Total Drama and is now preparing everything for a new season of the show.

For several instances, he tried to get some of the previous contestants and some of the Ultimates for the season. But he was rejected every time he tried. That was until yesterday, where he somehow tricked the nations into relieving the chosen contenders from their duties in exchange for offering entertainment to the world.

And here are the countries now, thinking of a way to get the fighters out of this. "We need to summon Chris and between the ten, explain to him why this can't work" Germany sternly said. "And maybe offer him some of my delicious sweet treats to make him more approachable!" China suggests.

"If that's the plan, then count me in! It's always good to solve a conflict without resorting to fight" Italy chirps as he waves his arms. "Let's summon him and ask him nicely. If he doesn't comply, then we simply break his limbs" Russia happily says, making everyone stare at him.

It seems nothing is going to result from this meeting when an alarm suddenly goes off. "What is happening?!" Mexico stands up from his seat. "Let me see!" Germany activates his laptop to check. "This makes no sense! There's nothing going on yet the alarm is active!" he groans in frustration.

The alarm then changes into a more frantic tone, meaning this requires everyone's presence. "We can figure that out later, summon the fighters!" Canada exclaims and leaves the room, with the others following him.

At the conference hall

The two generations of Total Drama, the 78th Class, and the countries who welcomed Ultimates are here

Everyone is yelling at the same time for the sudden summon as the ten main countries arrive. "Everyone, calm down!" Japan pleads to no avail. Duncan is bickering with Scott, Owen is devouring some snacks from the lobby. Alejandro is watching Heather and Aoi bicker.

Blaineley is watching the whole spectacle, clearly amused. But Kiyotaka is the one who puts an end to all confrontations with one simple yell. "SILENCE!"

Everyone in the room goes silent, "Thank you, Ishimaru-kun" Japan says. "Why did you summon us anyway, Kiku?" Heather snorts. "Heather! You have to show your country-mentor some respect!" Taka barks. The girl just rolls her eyes and offers a halfhearted apology.

It's not that Heather dislikes him, but the boy can sometimes get on her nerves, which in turn results in a lot of shenanigans for Japan.

"All right, we summoned you here for a reason" Germany said before activating the holographic table that everyone is using.

"That this is busted! Nothing is going on right now!" Toko says. "That's what worries me. This device is enhanced with magic so it shouldn't have any failures" England replies. "Maybe it just needs maintenance" Owen happily suggests.

Makoto and Canada sigh in a friendly manner before America takes the floor. "Let's figure out what is and if it's a bad guy, then we just kick their ass, hero style!". Duncan and Leon agree with him while Byakuya and England just roll their eyes.

Suddenly a huge rumble was felt from the table, reports from all over the world started to appear. "What just happened?!" Mexico asks, "According to these reports, a global scale earthquake just took place but strangely nothing or no one suffered any damage, aru" China says as he reads the articles.

And just as things couldn't go any crazier, a ripping sound begins to make its presence on the room and a rift opens.

"WHAT IS THAT?!" Everyone yells at unison. They stare at the rift and it looks like it conducts to somewhere struck by an apocalypse. And from the other side of the rift, a certain person from Makoto's life appeared.

At the other side of the rift

"It's time…" Juzo said as the rest of the foundation nods.

Komaru Naegi stood ready to cross the rift, "The time is now." she says with determination as the rest of the Future Foundation nod. Ever since they infiltrated the other dimension more than one year ago and found out their universe is gonna clash with this one, they've been bracing themselves for this very moment on top of working with restoring their world to its former glory.

Juzo stands alongside Komaru, with one final nod, the two of them cross the rift.

Everyone from the other Earth side of the rift is staring speechless as several people arrive from said rift. These people included: Komaru, Kyosuke, Juzo, Chisa, several heads of the Future Foundation and the 77th Class.

"Who are you?!" Heather asks, instinctively taking out her weapon. "Wait!" Makoto screams and approaches one of the visitors.

"Komaru?" Makoto subtly asks as the girl in question tearfully nods. "Makoto!" The girl tears up and runs to hug his brother, who in turn tears up a bit as well. And they weren't the only ones, the moment the 77th Class spotted Chiaki, who dropped her jaw.

In a matter of seconds, the whole class ran to her and gave her a group hug. And it only went downhill when the Total Drama cast and the 78th Class started to interact with the members of the foundation

"What is going on?" Germany asks, "Allow me to answer that" a man with a hair and white suit says before standing in front of the Nations and Earth's defenders.

"First of all, allow me to introduce myself. I'm Kyosuke Munakata, vice president of the Future Foundation. We come from another universe where the world was consumed by Despair; This was caused by a girl called Junko Enoshima, a.k.a. the Ultimate Despair" everyone from the Nation's Earth turned annoyed glances at said girl, who just mockingly waved her hand.

"And we were almost at the brink of eliminating that when this happened." he said before continuing.

"There's a reason why we are here and why that rift appeared:

Our dimensions have clashed and are now merging" Kyosuke bluntly said.

"What did you just say…?" Japan questions with worry, "Exactly what he said, short guy" Juzo snarked.

"But pourquoi this happened?" France exasperatedly asks. "I'll tell you why," Koichi Kizakura said as he pulled out a holographic tablet. The device projected the worlds and the man proceeded to explain.

"When Count Bleck conjured the Void, he made it appear across several worlds. Our world was far enough to be safe from the Void but also close enough for it to absorb some of the essence of the former, making it unstable and make it wander like an asteroid to a planet.

"What? How is that… wait. How do you know about the whole ordeal with Count Bleck?" America glares at the man. "Let's just say that we discovered it" Kyosuke simply responds.

"That explains why the merge happened, but why are you aqui?" Mexico snarls. "Because we wanted to seek your help in closing the rifts!" Chisa happily squeals.

"Exactly. And with that out of the way. Let's get to business" Juzo said. "Wait a minute mate, who said we were gonna do that?" Australia objects, with the rest of the countries nodding.

"We have to do this if we want to solve this problem. And on top of that, we need to know what to do with Junko Enoshima" Kyosuke coldly replies.

"It's quite intriguing why you let the girl that destroyed our world be around you" Chisa inquires.

If things weren't chaotic enough before this happened, this is pandemonium. Everyone present in the room started arguing with each other. Japan just sighed and pulled Heather and Taka out of their discussions.

Meanwhile, Italy got to draw in order to not be involved in any fights. But when he finished his drawing, he noticed something in the holographic table. He activated the holograms and saw several news of rifts appearing all over the world. But the frosting of the cake was when he saw some reports of a strange thing appearing above Niagara Falls.

"Hey, what is that?" the Italian naively wonders. Germany and Japan look up and widen their eyes, followed by everyone else. "The FUCK is that?!" Juzo and Romano yelled in unison. "We don't know. But for what it looks like as of right now, it can be a threat." Courtney intervened.

"I think I've seen this before. We have to call some reinforcements" Japan declares and he leaves the room.

The rest of the people in the room stared at the being in utter silence.

With Japan

The Country entered one of the several rooms of the base and took out his phone to do one and just one thing:

Contact Mario and any other mushroom hero available.

He proceeds to start a video call.

At the Mushroom Kingdom

Mario, Luigi, Peach, Yoshi, Donkey Kong, Daisy, Rosalina, Diddy Kong, Dixie Kong and Bowser are enjoying a banquet to celebrate King Boo and Hellen Gravely's defeat at the hands of Luigi.

It's been one pretty active year for them since the Smash tournament of last December. They made new friends, fought Galeem and Darkhon and altogether had a pretty good time. Just as they served the desserts and concluded this reunion, Toadsworth arrived to tell them something.

"Masters! There's an incoming call from the Earth!" he says. Mario and Peach quickly leave the table, followed by the others. Peach got to the laptop in the castle lobby that she was given to by England and turned it on. Once she accepted the call, the screen showed Japan with a worried expression.

"Greetings, my friends. I hope you are doing well"

"Japan!" Mario chirps, "It's been so long!". "How are you doing?" Peach asks. "To what honor we owe your call my friend?" Daisy wonders as the rest gathers to greet the nation. "In all honesty, this call it's not for pleasantries… It's a call for help" Japan seriously said.

The ten dropped their smiles and focused on Japan. "What can we do to help?" Luigi asks. "I need all of you to come here. Something horrible happened. We don't know what it is and we need your assistance with this" the country pleads.

"We're on our way!" Donkey Kong simply said and Japan nodded before activating one of the portal devices the countries made to cross between this and Mario's dimension and the call ends.

Mario and the rest leave the lobby and head to the backyard, where their portal device is.

The device is activated and one by one they cross it.

"Please return safe, masters" Toadsworth whispers before returning to the castle.

At Earth

The mushroom heroes arrived and they were greeted by Japan, after he exchanged a fist-bump with Mario, they headed to the conference hall where the rest were.

Upon arriving, they discover the fight that started earlier has ended and now everyone is taking a seat Taka and Heather (against her will) got up and approached Mario. "Mario, my friend! It has been a while!" the teen smiles as he shakes hands with Mario. Heather just sighs but gives a soft smile to Mario, "I guess it's better now that you're here, but don't push it".

Mario chuckles and greets everyone in the room as he and his friends take a seat. "What can we do to help you?" Rosalina asks. "With this" Canada answers as a hologram appears above the table and America begins to explain..

"These guys you see from another side come from the Ultimates' dimension, the one Junko sent to hell. And thanks to Count Bleck's actions more than one year ago is why we are here with this situation.

But that's not the worst part, look…" America also opened up a news flash coming from Niagara Falls.

What the ten mushroom heroes saw, made them fall in total silence.

The abomination that invaded the most recent Smash tournament: Galeem, is floating in the sky above the falls as tons of people are filming it.

"We have to go now…" Mario simply said. "And everyone here must come as well if we want a chance at beating it." Yoshi adds. The Countries, the Castmates, the Ultimates and the members of the Foundation watch the usually cheerful heroes being so serious meant this is huge.

"Let's get going, we may only have seconds before it acts" Dixie Kong declared. "Very well. Everyone, including the foundation, prepare yourselves, we're going to Niagara Falls" Germany said.

Everyone left the hall and the Nations asked the foundation members to follow them. But just as almost all left the room, South Korea grabbed Japan's arm. "Japan, please tell your other protegee to get there daze".

Japan recalled who South Korea is referring to and nodded. After his fellow nation left as well, the country pulled out his ear communicator and spoke. "Trevor, after you're done solving what happened in Egypt, head to Niagara Falls ASAP. Everyone will be there" Japan said before leaving the room as well and headed with the others.

With Trevor

The man received the message. The former Phantom Thief and Hero known as Laserblast has been living a lifestyle similar to what he had in P.O.I.N.T. and is using what he learned in his home world and Joker's world to live his life to the fullest in doing what he does best: Protect the innocent.

Trevor simply fixes up mask and finishes helping Egypt with rounding up some bandits and uses a warp bomb to head to his next destination.

"Whatever it's happening there, must be serious. Hang on there Japan, I'm on my way" Trevor says.

As everyone is making their way to the falls, no one suspects that what happens next, will make them taste… True Despair.

To be continued...

What is happening here?! Rifts are appearing in the Nation's universe, the Future Foundation has finally reached this world and Mario and co. have been summoned!
