I am Rimuru Tempest(Old Version. Rewrite is out.)

The first few chapters are a bit rough since I wasn't sure what I wanted the story to be like. And the story is a bit rushed until chapter 20-25ish since I wanted to get to the point after the kids get their spirits. After that, the story breaks from canon and slows down the pacing. Hopefully, you will give the story a chance. The joke at the beginning with sage is not indicative of how the story will progress, I just thought it would be funny at the time. ... You already know how it is. Someone gets reincarnated as Rimuru and decides that he wants to have a new life with a kingdom, a harem, and strong skills. I am a first-time writer so if you have any tips let me know. It's obvious but I don't own tensura nor its characters and the picture for the fanfic is not my art. If you are the artist of it let me know and I'll change it or add your name I just found the pic on google and wasn't sure who the artist was. I'll try to update regularly but I do have a full-time job so I probably can't do it daily.

There Are Kids Here And There, There Are Kids Everywhere.

(Recap of their kids at the end. Spent a while thinking of names, so I also left their meanings at the end. Next chapter is the start of the multiverse of madness.

Tomorrow's chapter is going to be 8k words. So buckle up.)

"Daddy! Daddy! Look! I am growing my fangs! That means I am getting stronger right? Soon I'll be able to beat up Homura!" A little girl with silvery-blue hair in two ponytails and bright blue eyes said in excitement as she showed a tooth that was barely poking out in her mouth.

Ruffled her hair before picking her up and telling her.

"Why do you want to beat up Homura? She likes you a lot, don't you know? You are her cute little sister. I'm sure she will be sad if you fight."

"But she is always pinching my cheeks! And I don't like it! Plus if I can beat her up that means I am getting stronger. And I want to be as strong as mom!" She said as she did a big explosion with her hands.

"Oh? Could it be that you want to take your mom's title of 'Little Nuke' Well I hereby declare you the Littlest Nuke." I told her as I pinched her nose.

She let out a small giggle as she hid her face with her hands.

"You know Aster. If you want to show Homura how to be a proper big sister then how about you show her by example? I am sure she will be impressed if she sees how well you take care of your siblings. Look, you can even start now!" I told her as I saw Shuna walk in while holding the hands of two smaller kids.

The twins both had cherry blossom-colored hair with golden eyes. With two skinny horns that were barely emerging out from their foreheads. One of them was a girl named Hanae, and the other was a boy named Ryoga. And they were both Shuna's kids that had just returned from a walk.

After I put Aster down she ran to Shuna before saying in a proud tone.

"Don't worry, I will take care of my little siblings. I can take them to play with Ranga and me. And I will make sure no one pinches their cheeks! Look, even my fangs are coming out now. That means I am a big girl now."

Shuna crouched down before ruffling her hair and then caressing her face.

"You are such a good big sis! I will make sure to make you some extra special food to celebrate your little fangs. Make sure not to let Hanae and Ryoga pull Ranga's fur. I know he says he doesn't mind it but we have to be nice."

"No Problem!" Aster said before leading the way with her two siblings waddling behind her.

Shuna gave me a quick kiss before asking.

"Where is everyone else? The house feels strangely quiet without everyone running around."

"Ciel is spending some time teaching Alder and Luna like usual. Fafnir and Homura are playing some time with Veldora. Hawthorn and Takeshi are with Shion and Ramiris practicing their 'fighting skills'. And Hinata went to visit Chloe with Shizue. Everyone else is either relaxing or taking a break.

Oh, and Terra is currently with Zegion. But they should be back sometime soon."

Shuna let out a small chuckle before asking.

"Is Zegion going to be ok? You know how Terra can get. Even Zegion might be in trouble."

Laughing along with her I answered.

"That's ok, she thinks Zegion is the best. And he is strong and smart enough to stop things from getting out of hand…. Hopefully."

"I'll make something special for Zegion and Callisto, as thanks." Shuna said while shaking her head with a smile.

She grabbed a basket and filled it up with different snacks before giving it to me.

"Could you take this to everyone? I am sure the kids must be getting a bit hungry. I'll start making dinner now. We can let them in on the surprise during dinner.

Since Ranga is outside I can take the snacks to Aster and the twins."

Grabbing the basket from her I took a bite out of one of the muffins before teleporting away as Shuna gave me a fake angry look while saying.

"Don't go stealing our kids' snacks."

My first stop was heading to Ciel. Ever since Terra had been born she had been spending most of her time outside raising her and helping with the others. And she had been taking the role of a teacher for everyone in the household. She made different teaching plans for everyone of the kids to fit their learning style. And let them develop at their own rate. After all, time was not something we were lacking.

The only one who had gotten the true hardcore learning experience was Ciel's daughter Terra. And the reason for that was simple, she was Ciel's daughter. She learned at a ridiculous rate. Ciel even had to manage Terra for a long time to make sure she didn't accidentally activate thought acceleration when she was a baby and get trapped in her own head for what felt like an eternity.

"Dad!" Alder and Luna shouted at the same time as I appeared before hugging me like a Koala.

Alder was a boy with Mint-colored hair and golden eyes. Just like his mother, Trya, he had inherited an interest in reading. And he was always going on about the things he had learned in one book or another. He had a small library in his bedroom filled with gifts from Lai. But thankfully, after a small warning from me that I might just throw her out into space, all of his books were appropriate for his age.

And Luna was the girl who had silvery blue hair and long elven ears with sky blue eyes. She was always very curious and loved learning. But she especially loved praying pranks on people. Her room was full of little trinkets she had built that was designed to be for pranks.

They were mostly just harmless pranks that she found hilarious, such as a soft ball with some space magic inscribed on it. So that when you threw it would teleport behind you and hit you in the head. But thanks to the ball being soft instead of hurting it would just make you confused. She called it the "Around the World Ball"

After ruffling their heads Ciel said.

"How about you show your dad what you learned today? I am sure he will be so impressed he will give you one of the snacks he is carrying."

I nodded in agreement.

"That's right. And if you really impress me you will get TWO snacks instead of one."

I spent some time with them as they began to showcase some of the things they had learnt throughout the day. With Alder showing some of his drawings and Luna showcasing her newest invention. And after spending some time with them I told them.

"Whoah! You kids are so smart, that I think you have earned Three snacks!" I told them while showing them the basket for them to pick.

They giggled for a moment before grabbing some of the food in the basket.

"Alright, dad's gotta go finish his snack trip. So make sure to study hard after you finish eating, ok?"

"Yes!" They said while munching on the food.

"Death to the non-believer!" Fafnir yelled while jumping to slash using his claws.

"You can never defeat us! We are the heroes of Tempest. And we will slay you demon lord Veldora!" Homura yelled as she shot out a massive amount of fire from her mouth.

Veldora, who was in his true dragon form, spotted me before letting out an evil laugh.

"Muahahahahaha, I eat heroes like you for breakfast. I will eat you and steal your powers and become the ruler of this world."

Veldora grabbed both kids in the air before softly tossing them in my direction.

And as I grabbed them in the air they looked at me with shock before letting out a wide grin.

"Dad! You have to help us defeat this evil monster!" Fafnir yelled.

He was Souka's son. With silvery blue hair and green eyes, he was showcasing his partial dragon transformation. He was capable of transforming into a full dragon form, though at the moment he was limited to a partial transformation like his mother. He had a fiery personality, and he was always full of energy.

With his partial transformation his arms, legs, and part of his face were covered in silver scales. With two wings and a tail he was still struggling to fully control behind him.

"That's right! This bringer of evil ate the food that Beretta brought us!" Added Homura.

Homura was also in a partial dragon transformation, with red scales covering her body. She had dark blue hair with golden eyes. She was an extremely caring big sister that liked to take care of all her siblings. But when it came to Fafnir they were both a force of chaos. Homura, who would be overprotective of her siblings, got easily influenced to help him whenever he decided to challenge someone.

"Muahahaha! And I would do it again!" Veldora shouted as he heard their words.

"Oh is that so? Alright, prepare for the Tempest team-up attack!" I told them as I placed them on the ground.

Sometime later we were sitting on top of Veldora's defeated "Corpse" while the kids ate some of the snacks with a slightly tired expression.

<<Can I move now. I didn't "die" in the most comfortable position.>> Veldora asked while still pretending to be dead.

Looking at my two kids I told them.

"Alright kids, remember, when you make a mess you have to pick up after yourself. So how about we wake up Veldora so that he can help you both cleanup?"

"Didn't you make a mess too? You are legally required to help us." Said Fafnir.

"Nope, your dad was quite careful to not damage anything. Not only that, but I have a special mission given to me. So I have to go deliver the snacks to your siblings!" I told them as I ruffled their hair and threw one of the snacks down to Veldora before leaving.

When I met up with Shion and Ramiris I spotted Hawthorn and Takeshi sitting on the ground watching their moms with awe as they did a mock battle.

Takeshi had a singular pitch-black horn in the middle of his forehead and purple hair accompanied by eyes of the same color. Most of the time he is extremely polite and well-mannered. But whenever he saw someone doing something cool he would get fired up and try to copy their movements and actions.

And Hawthorn had blonde hair, long ears, and golden eyes. With a pair of fairy wings in his back that were softly closing and opening. While he was a quiet kid you could tell that there was a lot going on in his head. And his unblinking eyes were watching the mock battle with absolute focus, trying to analyze every movement.

Shion and Ramiris noticed me and stopped the battle before waving at me.

Turning around they spotted me and Takeshi began to talk excitedly about the fight with Hawthorn nodding silently in the background. They both took some time to show me how strong they were getting by doing a few examples of what they had learned. With Hawthorne proudly showing off the modified 48 deadly attacks he had learned from his mother.

He had combined them with what I had taught him and he softly but proudly announced that he had created the 63 Hawthorn Thorns. The deadliest martial art to ever exist.

After giving them the snacks and spending some time with them I left.

Chloe was straddling holding a sleeping baby as she softly talked to Luminous who had baby toys all around her. It was Shizue, Hinata's daughter. As she spotted me, Chloe gave me a smile before patting the seat next to her.

"Hinata said that she needed to do some stretching, so she went to try to beat up Guy. She said that it had been the longest she had gone without fighting something since she came to this world." Chloe said with a soft tone.

I sat next to her as we began to talk in a soft tone to not disturb Shizue.

"She's so cute, isn't she?" Chloe said as she poked the sleeping child's nose.

"The cutest." Luminous said.

And so we began talking about random stuff for some time. Luminous gave Chloe a wink and a thumbs-up before disappearing.

Which left Chloe and me to talk by ourselves.

In the time since the wedding, a lot had happened between us. Up until the point where her tactical retreats completely vanished.

"You know, Hinata ended up stealing the name I had planned for the future," Chloe said as she looked at the baby in her arms.

"Is that so?" I asked her with a smile.

"Yeah. But looking at little Shizue I don't mind."

We hadn't yet gotten married. But it was only a matter of time now.

As nighttime was starting I grabbed Shizue from Chloe before returning back home. And when I got there I saw Zegion who had a small girl on his shoulders, Terra. With Crimson red eyes and silvery-blue long hair, she had an extremely big smile as she said.

"Dad! I made something cool! It's a slime dragon!! It came out a bit deformed at first but after some tries, I was able to make it properly! You have to come to meet Silly after dinner! He is so cute. I named him Silly because he is a slime and he looks Silly!" The excited girl said as she waved her arms around.

Terra may have been an absolute genius, but that didn't change the fact that she was still just a kid. And yes, I almost forgot, Terra had inherited my naming sense.

~A/N~

Rimuru is both a true dragon and an Origin slime. But I would imagine he would pass off the dragon part more than the slime. So here is what I think the kids and their races are. Mostly Dragonoid since I thought slime would fit in weird. I mean, Kijin Slime? Sounds weird.

Most names are just what I thought would fit their kids.

If you have any suggestions for a name for their new race let me know.

Ciel's daughter: Terra - Origin Slime/ True dragon.

Ciel means sky. Terra means earth. I thought it was a nice theme.

Lina's daughter: Luna - Elf/True dragon

Lina means sunlight. And Luna means moon, so I thought it was nice.

Shuna's twins: Hanae and Ryoga. - Kijin/True dragon

Hanae means blossom. And Ryoga means elegant.

Shion's son: Takeshi. - Kijin/True dragon

Takeshi means warrior.

Souka's son: Fafnir - True dragon (Dragonborn + true dragon)

After the mythical dragon.

Trya's son: Alder - Dryad/True dragon

Alder is a type of wood. So with Trya being a dryad, I thought it fit him.

Hinata's daughter: Shizue - Dragonoid. (True dragon + Human, same as Milim.)

In honor of Hinata's teacher, Shizue.

Milim's daughter: Aster - True Dragon.

Aster means star in Latin. Milim is the Star Dragonoid.

Ramiris' son: Hawthorn - Fairy/True dragon

Along the same lines as Alder. A nature-related name since Ramiris is the leader of the dryads and queen of spirits.

Velgrynd's daughter: Homura - True dragon

Homura means Blaze.
