Chapter 5

Over at a small city known as Rimuru, Rimuru Tempest is fighting against another one of those humanoids that has their body covered in black boxes. Rimuru tried to use Predator, but he cannot absorb him.

'How am I supposed to beat this guy?' Rimuru is frustrated as his trump card isn't working. 'This guy is completely immune to all of my magical attacks. Even worse, he seems to be able to detect and block any physical attacks. So how?'

Back at the capital city, many of the goblins, hobgoblins, high orcs, dragonewts and other such beings are fighting against the alien monsters from Natural Selection 2 and Evolve. Soei, one of the Kijin and Rimuru's spymaster, caught one of the goliaths with his sticky steel threads by the neck and decapitates it. Yet a fade tries to strike from behind but Souka manages to kick it in the jaw and sends it flying before standing back to back with Soei.

"What are these things?" Souka asks.

"I don't know." Soei responds as he is preparing to strike, "But they seem to be following the guy Lord Rimuru is fighting against."

Hakuro, a Kijin sword master, shows up and says, "Indeed, but some of them are acting more like animals than a hive-mind. There is more to them than they appear."

Over at the square, Milim Nava, a demon lord, killed a few gorgons in an instant and in a rage. "That's for ruining my lunch!"

A kraken tries to electrocute Milim but gets decapitated by Shion and her massive sword. Ranga, a tempest star wolf, uses black lightning on some of the monsters as he howls and lightning comes out of his horns. Many warriors are doing everything that they can to stop the monsters, some people are trying to put out the fires, and many try to evacuate.

Back in the sky, Rimuru tries to charge at the guy with his sword but gets blocked by the same diamond shields that's been blocking all physical attacks. Rimuru tries to use all the best sword moves that he could but the man seems to deflect every blow and strike as if he knows when and where the strike is coming from.

Rimuru backs off and asks, "Just who are you?!"

The man chuckles, "Glad to asks." He seems arrogant and overconfident. "My name is Dios Diablo. I am a Black Box Hunter."

"Dios Diablo?"

Great Sage says to Rimuru, "An error has been found. Dios Diablo and Black Box Hunter do not appear in my databanks."

'Kinda figured that much.' he says to Great Sage.

Dios continues to speak, "We have detected some sort of activation protocol from one of the black boxes that awoken us from our hibernation in the sun."

Rimuru is surprised, "You came from the sun?!"

"That's right. But back to the story. Someone in this solar system used some sort of hidden power of their black box that awoken us from our long slumber. Now we are hungry for more power. The more black boxes we absorb, the more power we get to have."

"We?"

"There are five of us in total that seek more black boxes. There's me, of course. There's Blake Obsidian, a talented fire user. There's Magna Newton, a man that specialize in gravity and can cause quite the storms. Then there's Covid Viral, a man full of deadly diseases and plagues who can even kill those immune to all viral infections. And finally, Shade Nightmare, one of the scariest dark users and can make nightmares into reality. But keep in mind; if you kill us all, the lifespan of the sun will shorten."

Rimuru grit his teeth at the situation he is in.

Great Sage speaks, 'No lie has been detected. Dios Diablo is speaking the truth.'

'That's the last thing I need.'

Dios floats a little closer to Rimuru, "Now give up and give me your black box. The more we collect, the longer the sun lasts."

Great Sage warns, 'Warning!: Removal of black box will result in death. Have to find alternative to defeat this new opponent.'

Rimuru takes a stance with his sword, 'Let's see how tough this guy is.'

Not too far, a bullet was fired and hit Dios by the right leg from behind. The bullet penetrated through his kneecap and flew by Rimuru's. Dios grits his teeth and tries to hold back all the pain that he felt. Dios slowly turn his head while holding back as he notices Team RWBY, Ainz and many others coming to Rimuru's aid. He looks at Ruby who is aiming her Crescent Rose at him.

'HER AGAIN!?' he thinks to himself in anger as the others approach and his legs regenerates. 'Oh that bitch will pay for that. Twice since she got two shots in.'

Ruby fires another shot yet Dios has his barrier up this time.

Great Sage finishes her analysis, 'Analysis indicate that a surprise assault is the best option for defeating Dios Diablo.'

Rimuru appears right behind him and tries to strike him down. But Dios was prepared for that with his barrier. After that, Dios simply vanished.

'It seems Dios Diablo has a teleportation skill.'

'Thank you for stating the obvious.' Rimuru says to Great Sage in a sarcastic tone.

Ainz, Team RWBY, Tanya and her squad, Ozpin, Bukubukuchagama and Touch Me arrived and stop close to Rimuru.

"Looks like we missed the action." Ainz says. He looks at the chaos below, "It looks like that creature is responsible for this."

Weiss takes a good look at Rimuru, "That's the slime?" She looks at Bukubukuchagama and remembers what Herohero looks like while comparing. "You don't look like a slime."

Ruby says, "We'll discuss this later, right now we need to help those people out!"

Rimuru says to everyone, "We'll discuss what I learned about that guy once things have settled down!"

Everyone heads over to the town to kill the monsters and save as many people as they could. Ainz remains up in the air as he cast a rain spell that might help with the fires. Weiss uses a water crystal and uses her glyph semblance to create a torrent of water to put out the bigger fires. Bukubukuchagama uses her defense capabilities to defend the people from the monsters while Touch Me, Blake and Yang fight against the monsters. Rimuru also uses his water manipulation ability to dowse the rest of the flames. Ruby helps out people getting people out of danger along with Tanya and her squad. Ruby moves some of the debris in one house to rescue anyone still alive.

"HELLO?!" Ruby shouts, "IS ANYONE HERE!?"

"OVER HERE!" says a voice of a young girl.

Ruby hears the voice coming from the dinning room of the house she is in. She sliced through some of the fallen wooden beams and rubble with her Crescent Rose to clear the way. Once she cleared the way, she meets a very familiar face. She sees a petite girl wearing a black hat that look like cat ears, bubblegum pink hair that has black hair clips with one having a bear on it and red eyes. Both of them look at each other for a few moments as they recognize each other.

"Yuki?" Ruby says as she looks at someone she met sometime ago, "Is that you?"

Yuki Takeya, a person Ruby and her team saved from a valley full of zombies and zealous psychos at the world they were stuck on, is here on this world.

Yuki smiles, "Ruby?" Yuki lunges and gives Ruby a hug, "Ruby it is you!" She smiles along with a little laugh with some tears in her eyes.

Ruby smiles as she pets Yuki's head with some tears in her eyes as well. Both of them are happy to see each other again.

After all the creatures have been wiped and the fires quenched, things have settled down. Ruby meets up with everyone else along with Yuki. Both of them talked about what happened on that day they got teleported into this new place. They all headed over towards Rimuru's house to discuss about the situation. It is pretty much like the last house Rimuru had in the other world he got reincarnated in. Japanese-style. Beside the fact, Rimuru discuss the situation and what he had learned.

"Are you serious?!" Ainz says in surprise.

"I'm afraid so." Rimuru says with a serious look on his face. "If he, or others like him die, the lifespan of our sun will grow shorter."

"Oh shit." Yang realizes.

Everyone look at Team RWBY and Ozpin.

Ozpin lowers his head, "I'm sorry to say this, but we killed one of them. The man did attack us and we had to defend ourselves. Should we just let him barge through and have his way? Or do we fight back?"

"That is a good point there." Tanya agrees with Ozpin. "When your life is being threaten, you have to fight to survive."

"You can say that again." Rhiner nods.

Matheus looks down with his eyes shut, "Too true."

Vooren's eyes are completely white and foam coming out of his mouth.

"Is he okay?" Yang asks out of concern for Vooren Glanz.

Viktoria looks at Vooren, "It's his post-traumatic stress syndrome from our winter combat training in the mountains. When the General mentioned 'fight for survival', he starts to remember our training."

Blake comments with a giant, anime sweat drop on her head, "That must've been some terrifying training."

"Yeah." Ruby agrees.

But Weiss stands up, "I'm sorry, but I would like to point out the elephant in the room. Sorry, elephants." She points at Tanya as she does some of her old complaining, "Why is there a little girl having the rank of general!?" Then points at Rimuru, "If that guy is a slime, why does he look like a human?!" Then she points at Ainz, Bukubukuchagama and Touch Me, "And why are there monsters being leaders along side humans?! Seriously, they look like they should be the bad guys! Are they even bad guys!?"

Ainz clears his throat (even though he doesn't have one) and speaks, "Truth is that we used to be players of a virtual reality massive multiplayer online role-playing game called, YGGDRASIL. Somehow we got fused with our avatars and ended up in this other, other world we are currently standing on. I used to be a Japanese businessman back on a planet called, Earth. When the game was shutting down, I somehow ended up in my avatar and into another world with the NPC's of the Great Tomb of Nazerick. Then we ended-up on this world and some of my friends are here too."

Bukubukuchagama speaks, "I used to be a voice actress on Earth that does anime and video games."

Touch Me looks away and stops sounding like some hero, "I used to be a worker myself."

Tanya answers, "I used to be a Japanese businessman myself. And yes, I was a man. Until some employee I fired wanted revenge and had me killed." Then Tanya looks angry, "But then I was reincarnated by the self-proclaimed god, Being-X into a form of a little girl in a world that is ravaged by war with people use magic and think that the constant falling of bombs solves everything." Tanya stands up with an evil smiling look on her face as she looks up, "One day, I will have my revenge!" She does a maniacal laugh that scares her soldiers and force them to huddle.

Rimuru says, "I used to be a Japanese businessman myself. As for my form, I am in my human form." Rimuru transforms into his slime form and shows he is a round, light blue colored slime. "See? I'm an adorable little slime monster! I'm not a bad slime, slurp!"

Ruby's eyes sparkle as she says, "Cutie!"

She tries to run up to him to snuggle him, but she senses something behind her. Behind her are Shion and Shura that are giving off menacing auras and stares at her. Shion is giving off a menacing purple aura with glowing yellow eyes while Shura is giving off a menacing pink aura with glowing red eyes.

Ruby sits back on her seat, "Okay, nevermind."

Weiss speaks, "At least somethings have been cleared up."

Rimuru goes back to his human form, "Good. Because I did find something interesting. I think the secret to beating this guy is surprise attacks or something he doesn't expect. He seems to know more about us here on Isekai." He looks at Team RWBY and Ozpin, "But not you guys. He doesn't seem to know about you and the rest of your people."

Ozpin looks at his black box, "Speaking of, we need to radio them." Ozpin activates the radio function of his black box.

Rimuru looks at Ainz and Tanya, "Did you guys know about the radio things in our black boxes?"

"Just recently when they showed up." Tanya says.

Ozpin says through the radio, "This is Ozpin, is everyone else doing alright?"

"This is Clover. We're having some difficulties finding the ship. Although it's a big ship so I have no idea on how the Protoss hide such a thing. We came into contact with the locals and faced off against one of those godly guys."

"Qrow here. We ran into some guy that has some power to make nightmares into reality and killed someone important. We're tracking him as we speak with some help."

"This is Winter Schnee reporting in. Found another one of those god-like humanoids that brought in zombies from the planet, Zom. We're helping the local militias and countries dealing with the undead threat. But there is something else. One of our own people just teleported here and has a black box. Right now, we're busy."

"Agent Carolina reporting in. We came across another god-like beings that can manipulate gravity and hurls a bunch of blocks at us. But we took care of him."

"Lysette reporting. The local leaders agreed to help us look for the ship."

"This is Raven. We finished evacuating the colony and heading towards Akua."

"Dr. Oobleck reporting in. I've made contact with Dr. Washu and learned more about Protoss technology. The Protoss were an amazing race. They seem to-"

Clover interrupts, "We'll discuss about them later, Doc. Let's focus on the task at hand."

Ozpin reports, "We ran into another one of the Black Box Hunters and learned more about them. Turns out that if we kill them, the sun's lifespan will get shorter so we may need to accelerate our time schedule. We don't have much time to explain, but we need those ships prime and ready when the Black Box Hunters are all dead. Understood?"

Everyone on the radio say in unison, "Understood."

Blake does some math and notice something doesn't add up. "There are supposed to be five of those Hunters, right? We already killed one and Carolina killed another one. We came across that Dios Diablo and might still be on the planet so now there are three. But from my count, there are four."

Weiss just say, "Probably Dios teleported to New Pandora or something."

Rimuru says, "No, the guy is still on this planet. Someone contacted me and said he is hiding out in a cave thirty miles away due southeast."

Ruby asks, "Then who's the extra?"

Yang looks down with her arms crossed, "I don't like this."

On New Pandora, a strange creature that seems to be part-human and part-insect with a mantis-like head just stare down from a mountain peak overlooking a town below in the middle of the night. On it's green humanoid insect body, there is a black box on its left arm. This bizarre creature just looks down with its yellow eyes intently as the night lights turn on. Hard to tell what an insect is thinking as it stares down at the town where the Ace Ops and Ironwood are at, trying to prepare the town for any sudden invasion. But that's exactly what this thing is planning.

It raises its arm up and starts to spawn creatures that are insect-based. These include Fire Ants from Fallout 3, human-sized Praying Mantises from Escape from Bug Island, some Nerubians from Warcraft, and Warrior Arachnids from Starship Troopers. The thing signal those creatures to attack the town and charge right at them. As they charge in, they cause the ground to shake by the sheer numbers as they charge right towards the town at full speed.

"OH SHIT!" Marrow yells out from a watchtower, "WE GOT TROUBLE!"

AN: Hey everyone. Hope you guys are doing alright with the whole Coronavirus thing happening. I wish this thing will blow over and things will get back to normal. Things have been crazy since it popped up here with grocery stores out of almost practically everything and I was lucky to get a few important items such as sanitizer, toilet paper and some food that will last me for a while. The office where I worked that is shut for the time being until it is safe and the place is being sanitized to prevent any sort of infection. Things are even worse with the 5.6 earthquake that hit and a 4 point something hours later. Good thing I wasn't at the center of it all or close to the source.

Funny story about that earthquake. It was seven a o'clock in the morning and I woke up to some sort of rumbling I was feeling. I screamed out, "WHAT THE FUCK WAS THAT!?" I looked around and everything seemed normal so I went back to sleep. Woke up at eight only to find out that there was an earthquake when I was listening to the news on my alarm clock. Then felt more rumbling and hid under my desk in my office room at home. I was prepared for that one.

You guys stay safe, stay healthy, and try to hang in there. A word of advice for these trying times. Make sure you wear rubber gloves when handling things outside your own home just to be on the safe side. Until then, see you later! Peace out!
