A/N: Another fanfiction idea that popped in my mind. I know I am posting a lot of stories, but this one will be different. This fanfiction story will be an actual crossover with a YouTube series that I fell in love with (Not literally), and that show is called SMG4, or Super Mario Glitchy 4 if you haven't seen or heard of him. One more thing, this takes place in yet another universe of 'Night Raid Watches Death Battle' so yeah, it has no connections to my other fanfictions. And for the SMG4 bit, it takes place in an alternate timeline after 'Mario goes to the dentist'. Now then, onto the story. And also, Insert Snow Fairy as the opening.

Disclaimer: I do not own Akame Ga Kill and SMG4. They belong to their rightful and respectful owners.

Episode 1: A Mad Scientist's Errand

Chapter Synopsis: Stylish asked Tatsumi to do a simple errand for him. Easy, isn't it?

Another day. Another day at Night Raid and there was nothing to do around the best except doing their hobbies. Many of the members are either just lazing around or just hunting these creatures called Danger Beast for fun. On the pathway that led from the base to the Revolutionary Army's HQ, a boy with medium brown hair and had two different colour eyes was walking towards the main base to pick up a special item for a specific Scientist.

"Why did I accept this?" The man who was Tatsumi thought to himself as that was still fresh in his mind.

"You want me to do what now?" He asked the Mad Scientist while they were in a meeting room back in Night Raid's base.

"I want you to pick up something for me in HQ." Stylish repeated again as he was looking over his schematic for an upcoming project that he was working on.

"Why me?" Tatsumi asked as he could have picked anyone besides him from the base.

"Because you were the first person that I set my eyes on." He simply answered as he took a sip from his freshly made coffee that he made.

Well, that was indeed true, Stylish did went to training ground first, and Tatsumi was the only one present. But still the other boy was curious. "Okay, what do you want me to do?"

The mad scientist realised that Tatsumi didn't know what he was going to pick up from HQ. "There's a delivery that I ordered which was very valuable, but I did manage to get it off from someone after…. A simple discussion. But since it's valuable and might give out this base's location, I figured that it would be simpler to deliver it to the Revolutionary Army's HQ instead so it would be in safe hands."

"Oh right." Tatsumi said as he knew the reason why the doctor wanted it to be sent to HQ. "So, when do you want me to pick up this package for you?"

"Hmm, let's say, since the project won't be completed by tomorrow because it isn't stylish enough, I want you to pick it up first thing in the morning."

"Wait, you mean tomorrow right?" Tatsumi asked the obvious question.

"Yes, tomorrow." Stylish responded as he set his mug down in the table.

"Okay, well then. I'll tell boss about this then." He said as he walked towards the door and soon left the room to go where his boss, Najenda was, who was probably in her personal room with Susanoo doing some paperwork.

As Tatsumi left the room, Stylish looked at his schematics again, which seemed to be some sort of box shaped device that had a lot of details in it.

"Let's see how I can improve on this." He said as he got out a pencil from his pocket and he began to make some improvements of his upcoming project.

And that's all what happened yesterday. Tatsumi just accepted the scientist's request to go to retrieve some special package from HQ. This must've been something important because Stylish had said that it was rather expensive, but he managed to persuade someone to sell that item to him. That also made Tatsumi imagine what kind of object was he talking about. Was it some sort of Danger Beast? Or rather an expensive souvenir?

While he was thinking about them, Tatsumi also saw the headquarters of the revolutionary Army up ahead. He was glad that this trip didn't take long. He was also lucky that he didn't get to use Incursio, his Imperial Arm, since there weren't any Danger Beast that he had encountered. This meant that he was also lucky that he didn't use Incursio's armour, which evolved in a dangerous state and he only had four usage left.

Tatsumi could see multiple Revolutionary soldiers doing their usual routines around the base. They would be surprised to see one member of Night Raid coming to visit HQ. But he wasn't there for a visit. He was there to pick up something for Stylish.

"Alright, time to pick up the package." Tatsumi said as he walked towards the base.

C

As Tatsumi entered the HQ of the Revolutionary Army, he already expected for multiple soldiers to eye on him. He can also hear some murmurs from them as well. "Hey, isn't that Tatsumi, a member of Night Raid?"

"It is. What is he doing here?"

"I don't know, did General Najenda send him here?"

"I doubt that. She hasn't even sent a letter at all."

Despite making comments, Tatsumi just simply ignored them. He was only here just to pick up Dr. Stylish's package and nothing else. However, one of the soldiers then walked up to him. "You're Tatsumi right?"

Tatsumi just stopped in his tracks and looked at a woman, who was in a doctor's uniform. It seems like this was something important as the doctor really had a serious look on her face. "Uh, yeah I am."

"Are you here to pick up a package, right?" She asked again.

"Yes, I am. By the request of Dr. Stylish." Tatsumi answered again.

"Oh good, I'm glad you made it just in time." The female doctor said before she turned around to begin walking towards one of the tents. "Follow me please. I'll show you where the package is."

The two then began walking towards the tent that she was saying about. It wasn't a long walk at it was only just a five minute walk. But before the two can enter, the woman stopped in front of the tent. "Wait here, I'll bring it to you."

"If you say so." Tatsumi said before he let the woman went inside of the tent where she was going to get her tent. As she was getting it, Tatsumi looked around the area that he was in and saw that there seemed to be nothing going on at all. Well, it seemed like there are more people that are joining the Revolution to fight against the corrupted Empire.

After a couple of minutes, the woman back out from her tent and soon she straightened her left arm and opened her hands to reveal a rather unique object. It seemed to be some stick or some as it was Crimson Red and Black as it colours. Tatsumi was absolutely confused by what he was seeing. "Uh, what is this?"

"The package for Dr. Stylish." She simply answered.

So the 'thing' that was in her hand was the package. But still, Tatsumi still wondered about it. "So, what is it called?"

"I honestly don't know. All that I know was that the merchant who was selling that it came from a river. It seemed to be wet upon retrieving it from the an underwater ruin, but he manages to dry it out before he even sold it to Stylish."

"Wait, that came from a ruin?" Tatsumi said who still had a dumbfounded tone within his voice.

"Well, what did I just said earlier?" She said as sarcasm was dripping on her voice.

Now that was confusing. If that was found in an underwater ruin, then why did it look advance? It seems to be more akin to an Imperial Arm by the look of it. It was then that Tatsumi realised that he was wasting time and that the Mad Scientist was probably waiting for the package now. He soon swept the package from the female doctor's hand and he put it in his pocket for safe measures. "I'll be going then. See ya." He began to rush out of the base anime style.

As the female doctor see Tatsumi run out of HQ quickly for some odd reason, she thought of something that she might forgot to tell him about. It was then at that moment that she knew she forgot to tell him one key note about the device. "Oh yeah…."

C

That was quite a day for Tatsumi. First, he was walking calmly towards HQ, and now he was quickly running back towards Night Raid's base since the doctor may be finished with his project. He was lucky that the package was still in his pocket that was safe from falling off.

He kept running for a few minutes and having no rest breaks while also using his assassin skills to get back to give the doctor his package. This lasted for a few minutes until he saw the base. Tatsumi manages to avoid Lubbock's Cross Tails since he entered the part where the traps were and then resumed running.

As he zoomed inside of the base, Tatsumi already knew where the doctor might be. In the basement. He continued running for a few seconds until he reached the door where the basement was. He slammed the door loudly, which made a thud sound.

"I got your package, Stylish." He said while panting heavily.

The doctor, who was in the floor thanks to Tatsumi slamming the door loudly got up and looked at him. "Ah, Mr Tatsumi. I'm glad you made it just in time for my new stylish invention."

"Of course you would say that." Tatsumi commented in his head while letting out a small sigh. He manages to catch his breath and walked towards where the doctor was. He saw that on the table that there seemed to be a Blue and white coloured small cube shaped object. This must be his new invention that he saw on the scientist's Schematics yesterday. "So, this is your new invention? Huh, it seems….."

"Stylish?" Stylish cheerfully said as he remove his Imperial Arm, Perfector and set them on the table.

"Something like that." Tatsumi added as he didn't want to say that word.

"Well, since you made it here in time, why won't you do the honour by inserting that package inside of the cube." Stylish requested as he was pointed at where the insert slot was.

That seems simple enough. It was an easy task after all for the boy. Taking the thing from his pocket which he had placed there earlier, Tatsumi then put it into the slot of the newly invented machine. "That didn't do anything. So….." He looked at Stylish who was also looking at him, "What does this invention of yours do?"

"Well, it is a replica of a-" Stylish was about to say when all of a sudden the cube started to shake on the table. Not only that, but the shake seemed to be powerful, that he and Tatsumi even felt the it.

"Umm…. Have you tested this thing out yet, Sty-" Tatsumi asked before he was interrupted the sound of rumbling.

The cube seemed to shake once again but this time it was violent that it shook the base. Tatsumi and Stylish seemed to feel it once again, and it continued to rumble until it was glowing blue.

"Oh no!" Stylish said before he duck for cover.

"What do you me oh n-" Tatsumi said before a red electric unknowingly zapped him.

As soon as the red electric hit the young boy, smoke begins to fill the room. In an instant, the smoke soon disappears and Tatsumi and the object was no where to be found. It….. seems like they disappeared without a trace.

Stylish, who was expecting an explosion, was then dumbfounded at his expectation. He then went from where he was hiding to only find that his invention, as well as Tatsumi was missing. Not only that, but Incursio seemed to be gone as well.

"Oh dear." The mad scientist said. He was sure that he made every adjustments to it and also check for any faults in it. This was both shocking and strange. Shocking that even though his invention was a success, it manages to suck itself in alongside Tatsumi, but strange at the same time as it didn't create an explosion.

Now that Tatsumi was gone, Mine, Cheslea and his superior, Esdeath was going to be mad at him for Tatsumi's disappearance. He knew that they are going to probably torture him, which he let out an imaginative sweat drop from his forehead. He soon got out from the basement and decided to tell the others what had happened. "This won't be good news." He said before he walked to where the meeting room was.
