Chapter 4

Team RWBY, Shinobu and the rest of Rooster Teeth are facing a crisis! There is someone covered in black boxes and completely destroyed the nine mercenaries from Team Fortress 2.

The mysterious man looks at Ruby and Shinobu who are trying to hide behind a building. "About time you showed up." the man speaks in a low-tone, demonic voice. "Prepare to have your power removed and added to my collection."

Shinobu throws three throwing needles at the guy yet he set up a wall of flames that completely melted the needles to nothing.

"Not good." Shinobu addresses the situation.

Carolina tries to fire her pistol yet has no effect. The charred up man with obsidian hair floats his way towards Shinobu and Ruby.

When Carolina runs out of ammo, she looks at the pistol as she angrily shouts, "For fuck's sake!" Then pulls out the BR55 battle rifle and tries to shoot his head off.

Team RWBY and Shinobu try to fall back as they run down the alleyway to avoid this new enemy. Yet the man blasts his way through the building as he comes closer.

"Oh, don't worry." the man smirks, "You will join the others real soon as my five brothers-in-arms collect the rest."

Marrow tries shooting his weapon along with Qrow as Vine tries to use his semblance and Clover uses his Kingfisher. Yet the bullets have no effect and Vine's left aura hand got burned with his real hand to pulls away. Clover's hook got melted immediately before it touches the man. Harriet tires to get closer but the heatwave emanating from his body repels her so she couldn't get a single strike. The five girls try to get away from the man yet he keeps on chasing them as if he is locked on to them. Ruby turns around and fires a bullet at the man. The smirk on his face disappears as he defends himself by blasting the incoming bullet.

"Wait a minute..." Ruby says to herself as she realizes what to do. So she petal burst as she leads the group to another alleyway. She reforms as she says to the group, "Guys! I have an idea!"

Everyone try to use their range attacks as the robots show up and throw everything they got at him. Rockets, bullets, lasers, plasmas, everything yet nothing works. The man looks around to try to find Ruby and Shinobu while completely ignoring all the fire being thrown at him.

Yang appears on the top of one of the rooftops as she slams her fists together. "HEY, ASSHOLE!" she shouts at him.

The man looks uninterested as he looks at Yang. "Where are the two?"

Yang jumps up as her eyes turn red as she is about to land a bunch.

"Really?" he says with some slight amusement. "Do you really think that-" Yang punches the guy in the face and actually did some damage! Yang lands on another rooftop as the man screams out, "YEEEEEEOOOOOOWWWW!" His voice changed from demonic to normal after getting hit. He drops to the ground, rolls and screams in pain. "OW! OW! OW!" He looks at Yang, "YOU FUCKING BITCH! THAT HURTS!" He then notices that Yang's implant has changed to a black box. "What the hell?! There wasn't a black box there!"

Yang grins at the guy, "Oh that!? You have my sister to thank!"

"Wait what?"

A gunshot was fired at the man's nose that shot right through.

The man screams out in pain again, "AAAAAHH! MY POOR NOSE!" Yet it regenerated. He looks at the direction of the shot and sees Blake with her Gambol Shroud in gun mode.

Carolina then shows up and punches the man right in the face followed by a flurry of punches because she has a black box. She grabs the man by his left ankle, yanks him and elbows him in the face. She then throws him over towards Ruby as she uses Crescent Rose to chop-off the man's arm. The man is flung towards one of the shops as his arm falls to the ground. The arm with black boxes suddenly turns into a multiple of black boxes. Five dozen in fact. The man shakes his head as he tries to get back up. He looks at his arm as it grew back. However, the black boxes are no longer there as he screams.

"HOW DARE YOU!" he angrily shouts at the people responsible. "YOU MADE ME FEEL PAIN AND NOW I LOST MOST OF MY POWER! BECAUSE OF YOU, THE OTHERS ARE GONNA KILL ME! I'M ALREADY WEAKER THAN THE REST AND-"

Qrow then follows it up by chopping the guy's head with his Harbinger in scythe form. The head falls down to the rubble as it, and the rest of his body, started to turn into a lot of black boxes.

Qrow looks at Team RWBY, Carolina, Shinobu, and everyone else that showed up as he says, "Wait, did he say others?"

"I heard that." Shinobu says with a serious look, "He said 'five brothers-in-arms'."

Carolina adds, "Then that means..."

Everyone look up at the sky to see all the moons and the gas giants as they realize that there are five more of those monsters that can only be taken out by those with black boxes. The guy said he was the weakest. Which means that the others must be stronger than him.

Ruby looks and everyone, "We need to form a plan immediately!" She looks at Harriet, "Harriet! Get the Council together!" She looks at Shinobu, "Shinobu, you need to head the gate, too!" She looks at her team and everyone else, "We need to get everyone together, now!"

After a few minutes, everyone has gathered at the entrance to the town as a small stage was made with the council members on it. Everyone, including non-combatants, are gathered to see what is gonna happen as Ruby takes the stage. Ruby is a little timid, but musters all the courage she has because there is a larger threat out there. To add on top of that, the sun is also about to go out.

Ruby clears her throat before speaking to the microphone, "Everyone, we have an emergency! We have a new threat that just bashed through the gates and now is threatening everyone else that have been surviving longer than us! Not only that, our sun is gonna go out in a few years! The arkships are located on these planets which means that the might be in peril!"

Raven then takes the microphone, "That's right! More of those people that attack us will also destroy the arkships and leave us stranded until we build our own ship from scratch which will take much longer and the ship parts from the sky will ruin any chances of us surviving! Everyone, including those of other worlds, will work together to guarantee survival!"

Salem takes the mic, "In order to deal with this new threat, we'll use these!" She shows the black box, "These are our only weapons against the new threat!" She demonstrates, "All you have to do is place it on your implant and it transforms!" The black box got infused into her implant and she can now use everything that you expect to use from the black box. "With these, we can fight against our enemy on equal footing!"

Then Doyle takes the mic, "We decided that there will be teams that will go out and take on these enemies! Despite the lack of information on this, these are desperate times! We need to find the ships, get everyone together, and get out before the sun goes nova!"

Ironwood then takes the mic to announce the teams and where do they go. "Team RWBY and Ozpin will go with Shinobu to Isekai to assist the locals against this new threat. The Ace Operatives and I are heading towards New Pandora to look for one of the arkships. Team NEON and Qrow Branwen will head towards Mutag to stop one of those god-like humanoids. Team SSSN and Dr. Oobleck will head towards Akua to locate Dr. Washu to learn more about the arkships. Team FAME and Winter Schnee will head towards Apocalyptica to fight and rescue. Team CFVY and Team NYON will go with Lysette Atratus and Agent Carolina to Overworld and Biome to rescue people and find the arkship. Team SLVR with Raven Branwen will head towards Colony 45468B to rescue colonist. That is all."

Sarge says, "Wait a minute! Have you forgotten about someone? The most capable, handsome and the most eligible and competent team of them all. The Red Team!"

"No, Sarge. You and everyone else need to stay here to secure our home. Agent Washington will keep on eye on you (and just you) to make sure you wouldn't run off."

"Dammit!" Sarge looks down in disappointment.

"Oh thank god!" Grif gets bow legged and looks up at the sky in relief.

"Thank god indeed." Simmons is relieved that he isn't going to go in any danger.

Ironwood smiles, "But we will contact you as backup in case of an emergency."

Sarge raises is head and sounds pleased, "Really?!"

Grif is disappointed, "Please, don't call for backup."

Almost everyone got their black boxes as their implants transform. Everyone that got assigned head out as they fly into outer space to where they need to be. Everyone else try to rebuild with their own black boxes and clean-up.

AN: Okay, some of the chapters are gonna be focus on certain groups at a time. One or more chapter will focus on one group for a while and then we get to see what the next group is doing. So it's gonna be one of those stories for a bit.

Team RWBY and Ozpin along with Shinobu fly up into outer space to reach the moon, Isekai.

"Any idea what we're gonna deal with?!" Ruby asks Shinobu.

"We're gonna head towards the capital of this world to see if they got hit! Once clear, we can try to find one of those things to make sure we can save as many people as possible!"

Yang then asks, "What if the guy we're gonna face is different from that flame guy?!"

"Then we'll make do with what we can!" Weiss says. "Let's focus on saving people first then fight!"

They all made it to Isekai as they try to head down pass the atmosphere as they follow Shinobu through the clouds. Once pass, they see a fantasy medieval city where a certain tomb is located. Yet there is a problem, parts of the buildings are demolished and a fire is set a blaze. People of all kinds of species try to run for their lives or put out the fires with water spells or any means of using water. There is even a fight happening towards the western side of the city where some members of the Isekai Council try to fight against another one of those humanoids with black boxes over his body, yet this one's different. This one's skin is pale white with long, white hair that glisten like diamonds. His eyes are of a pale blue with a slit pupil. He has an average muscular build with black boxes all over his body in certain sections.

A skeleton in fancy robes and a golden staff says, "Dragon Lightning!"

A dragon-shape lightning came out of the skeleton's right hand and proceeds to strike the man.

A man in white with a red staff, glasses and messy black hair shouts, "Thorn Bind Hostage!"

The man is then wrapped in glowing purple thorns.

More attacks came from a girl in black and red armor with a giant shield as she raises her dagger, "Hydra!" and three purple hydra heads appear and spew poison.

Another one came from the side by a girl in a blue robe and brown hair with a ponytail uses her staff as she fires a blue fireball followed by a gun being fired by a man in a black coat, white hair, one red eye while the other has an eye patch and a prosthetic arm. The man stands there as he takes in the barrage of magical attacks yet deflected bullets by the use of some sort of magical barrier. As the attacks hit, they didn't do any damage. Everyone notice that their magical attacks have absolutely no effect.

The man smirks, "I'll admit, it was a good try. Rin Azuma. Satoru Suzuki. Hajime Nagumo. Kei Shirogane. And Kaede Honjo. Right?"

Everyone are completely shocked by the fact that he knows their names. Even more shocking to Ainz, Shiro and Maple who have always been using their gamer names rather than real names. This terrifies them.

"How?" Shiro asks with a terrified expression. "How does he know our real names?"

From above, a small female child with blonde hair shouts, "FIRE!"

A volley of gunshots are fired upon the man. Yet they're not ordinary rounds being fired from a squad flying in the air. They are magical bullets that explode on impact. However, the guy had his barrier up and not a single shot was hit.

The man looked up at the sky to see Tanya von Degurechaff and members of her battalion. "Well, well." he smirks. "If it ain't the former Japanese salary man that got turned into a little girl by what she calls, Being X."

Tanya gets startled when she years what the man said. She takes aim as she tries to activate her jewel with a prayer. Unfortunately, the man appeared behind Tanya in a blink of an eye.

"Ain't that ironic."

Tanya stops what she is doing and tries to fly away from the man.

"GENERAL!" Viktoria aims her gun and fires three rounds at him but has no effect.

The man laughs, "Seriously?" she looks at Viktoria. "Clearly you still don't understand- GYAH!" The man shouted in pain as he notices two metal needles on his left shoulder. He looks up and sees Team RWBY, Ozpin and Shinobu flying from above. The man grit his teeth, 'Shit! Who the hell are they?!'

Ruby aims her Crescent Rose and fires. However, he saw that coming and activate his barrier and even stops Tanya's surprise bayonet attack.

The man says to everyone around him, "I'll be back!" He sounds upset about the situation he is currently in and flies away in an instant.

Everyone lands on the ground.

Ruby asks, "Is everyone alri-" When she sees Ainz, she aims Crescent Rose with her teammates aiming at the guy.

"Wait!" Shinobu stops them by getting in their line of fire. "This guy's a member of the Isekai Council!"

Weiss is a bit confuse, "That THING is part of your council?"

"Hello?!" Ruby's black box made a sound and it sounds like Yoko from Team NYON. "Oh hey! I found a phone function!"

Ruby looks at her black box. "Is that you, Yoko?"

Yoko sounds excited, "Hey, Ruby! I found out you can now call people on this thing!"

Ainz look at Tanaya who is just floating to his left, "I didn't know about that."

"Neither did I." Tanya says to Ainz.

"Yeah, we discover how blocky this place is. I love it! Oh, got to go, bad guy over at some tower!"

Ainz is a little confuse as he just asks, "Um, who are you?"

Ozpin introduces himself, "Greetings. I am Prof. Ozpin and a member of the Rooster Teeth Council."

Tanya has one eyebrows raised, "Rooster Teeth?"

Then he introduces everyone else, "This is Ruby Rose, Weiss Schnee, Blake Belladonna and Yang Xiao Long."

Ruby jumps in, "And together, we're Team RWBY!"

Ainz and Tanya look at each other and go, "Eh?"

Tanya's squad look at each other and don't get it.

Shiro approach, "Either way, we now have some help." He pushes his glasses as everyone else comes forth.

Maple approaches, "No kidding. With a monster like that, we need all the help we can get."

Ainz extends his hand, "I am Ainz Ooal Gown. A member of the Isekai Council."

Ozpin shakes Ainz's hand.

Weiss shouts, "Excuse me! We still have a burning city and a black box hunting naked guy to track!"

Rin says, "I'll handle the fires in the-"

Before she finishes, they see a large ball of water up in the sky just over the city. The water ball bursts and all the water comes down and put out the fires and everyone got soaking wet.

Blake looks wet and miserable, "What the hell was that?"

Ainz does a disappointed sigh, "That would be Aqua. The self-proclaimed water goddess."

Weiss looks at Ainz, "How can you make a sigh if you don't have any lungs?"

Yang asks Weiss, "That's the only weird thing you asks?"

Afterwards, most of them head inside as repairs are in progress. Team RWBY and Ozpin get to meet some of the members of the old Ainz Ooal Gown guild such as Touch Me, Peroroncino, Bukubukuchagama, Herohero, and Ulbert Alain Odle. Also with them are other members of the Isekai Council that are currently present such as Tsukasa Mikogami from High School Prodigies Have It Easy Even In Another World along with Shinobu, Kazuma Sato from KonoSuba along with Aqua, General Tanya von Degurechaff from the Saga of Tanya the Evil, Subaru Natsuki from Re:Zero along with his aides Emilia and Ren, Shiro from Log Horizon, and Shinichi Kano from Outbreak Company along with his half-elven maid, Myucel Fourant. That's pretty much it of the Isekai Council. The rest are busy doing repairs or busy with their own towns since it is close to December. Team RWBY find most of them a little off putting but put their feelings aside for now.

Ozpin approach the leaders with his hand extended, "Greetings. I am Prof. Ozpin. One of the council members of Rooster Teeth and former headmaster of Beacon Academy."

Tsukasa gives him a friendly handshake, "Hello. My name is Tsukasa Mikogami. A member of the Isekai Council and prime minister of the Elm Republic."

Team RWBY then introduce themselves and everyone else exchange greetings. Afterwards, they talk about the situation they are in right now and what is gonna happen. Team RWBY and Ozpin told them about one of the humanoids that they fought back on Menagerie. They told them that the only way to beat them is by having a black box since the only way to defeat someone with a black box is with another black box on their arm (or for some, other places).

"I see." Ainz is intrigued. "So the only way to beat someone like that is by having a black box yourself?"

"That's right." Blake nods.

Ruby says, "It wasn't easy, but we did take him down."

Peroronchino asks, "And that guy said he was the weakest out of the six?"

"That's correct." Weiss answers.

Tanya has her arms crossed, "Yet that guy seems to be immune to all magical attacks. When we try to do physical attacks, he seems to have some sort of barrier."

Yet Shinobu points at herself, "But I managed to do some damage."

Herohero goes, "Hmm..."

Shinichi looks at Herohero, "Hey. Are you thinking what I think your thinking?"

"It seems that surprise attacks work on that man. His defensive barrier doesn't seem to have an auto function. But I doubt that is the case." Herohero makes a good observation.

"Maybe he also has some sort of motion tracker?" Blake suggests. "The Reds and Blues told us that their motion trackers can detect movement but not how high or how low where the target is. We came barging in when he was busy with Tanya's squad."

Subaru says, "It might work."

Everyone look at each other and have a look that suggest that they have an idea.

Ainz looks at everyone and asks, "So, do we have a plan of attack?"

Everyone nods.

"Very well. Once we dealt with this new threat, we will get as much as we can and board the arkships." Ainz looks down, "It's a shame we have to leave Nazerick behind." Yet after that moment, he gets a call via telepathic link. It's sorta like calling a friend via message. He looks at his HUD and sees that Rimuru Tempest is calling. "Rimuru?" He answers, "Yes, Rimuru? What is it?"

Weiss looks at Bukubukuchagama, "Who's Rimuru?"

"He's a powerful slime that rules over the Jura Tempest Federation."

Weiss gets creeped out, "Another slime?"

"WHAT?!" Ainz let out a shout. "We'll be right there!" Ainz hung up and looks at everyone. "Rimuru asked for our help! The man is attacking the Jura Tempest Federation!"

Over at the Jura Tempest Federation, at the capital of Rimuru, the man summoned a horde of alien monsters from Natural Selection 2 and Evolve. Rimuru's forces put down as many as they could yet lost a few of their numbers. Up above Rimuru tries to use his unique skill: Predator on the invader. Rimuru tries to use his slimy body to wrap the man up, but there is a problem.

Great Sage says, "System Error. Unable to use the unique skill: Predator on target."

Rimuru backed away to resume his human form with bat wings. "Damn!" he says in frustration. 'How am I supposed to beat this guy?!'

The man he is facing smirks as he prepares to attack.

AN: Hey everyone! I hope you enjoy this new chapter. By the way, due to my crazy work schedule, I will upload new chapters whenever I get the chance rather than a couple or three every two weeks. Until then, see you guys later.
