Hello it's me Rimuru Tempest the demon lord Slime who is well known for world domination and at the moment I am in the biggest boredom of my life.

It has been several years since the final battle against Yuuki. This battle was quite difficult and it took a long time to repair all the damage, but after a while the world was stabilized and now everyone can live in peace.

What do I think about this? It is boring. My subordinates take care of everything for me and I have nothing to do. Our civilization is not that evolved, so it's not like I can play video games or anything. The only way I am entertained is when I am with a certain person...

Today I decided to do something to escape this boredom. I then talked with my skill Ciel who is the smartest person I know. Ciel then suggested something to me.

●●●

I gathered all my executives and important friends in the boardroom. Everyone was sitting at a large table and I stood up to speak.

"Okay I'm going to be reincarnated in another world"

I declared as if it was something normal, obvious just as I thought it caused....

"""Huh!?"""

Everyone got dumbfounded expressions and let out confused groans. Their reaction was normal since I didn't say anything about it before.

"Rimuru-sama, what do you mean?"

Rigurd came forward and asked me, the others also seemed to want to know.

"Exactly what I said before, I've been bored and these last few years I've been wanting a more lively life. Don't worry, I will come back in a maximum of 100 years and leave everything here with you.

I will also leave contact methods in case of emergencies, I talked to Ciel and was told that since I am a higher level Spirit Form I don't need a body or anything like that so I will reincarnate in my old world. So I can reincarnate by transferring myself into a human body."

I explained and everyone had thoughtful faces. Some of them looked like they didn't want that, but no one seemed to want to stop me.

That was the tip Ciel gave me to get out of my boredom. I don't know in which universe I will be reincarnated because I left everything to Ciel, but since I trust him, I think it will be a great life.

Shion and Diablo came closer and bowed deeply.

"Rimuru-Sama allow us to go together."

They spoke and I rejected it on the spot. I didn't want them doing everything for me in the other world. That was because I would probably get bored again.

"No, this is something I want to do alone. Besides, I need you guys to take care of things here."

They looked reluctant but did not object to my words. They raised their heads and returned to their seats. The others also seemed to want to go along with me, but said nothing. I then continued to speak.

"Okay then, I'll say goodbye to the people and go tomorrow. I will leave an unwilling clone that you can control so that my 'trip' doesn't become public. The meeting is adjourned."

I would leave a clone so as not to make anything public. If the "most powerful demon lord of them all" wasn't around, several rebellions could happen and that would be problematic.

I would leave a clone so as not to make anything public. If the "most powerful demon lord of them all" wasn't around, several rebellions could happen and that would be problematic.

I said goodbye to several people important to me and people who needed to know. The rest I left with my subordinates, I have extreme confidence in them.  

By the way, when I told my friend Veldora about my trip his reaction was

"Kuahaha, don't worry, as long as I'm here nothing will happen!"

That kind of sentence was typical of him so I just smiled and agreed.

●●●

[Producing new body, age 1 day, gender: not existing].

("Wait Ciel-san it's going to be weird that I'm a genderless human, make me a male body.")

A day later I said goodbye and then started to reincarnate, I won't explain this process to you because when Ciel explained it to me even I didn't understand so I just said "reincarnate me into a fun life" and the process started

[Producing new body, age 1 day, gender: not existing].

("Wait Ciel-san it's going to be weird that I'm a genderless human, make me a male body.")

[.....]

("Ciel-san?")

[.....]

("Ciel-san!")

[.....OK]

("These times I've been thinking that Ciel looked like cyumes of the girls close to me, but there's no way my ability is in love with me right?")

[...Right.]]Algorithmically blushing[

I thought Ciel was acting weird, but it must be my imagination. Ciel then continued the process.

[Ok male body formed, baby size, world; land, country of origin; Japan parents' name; Nagumo Shuu and Nagumo Sumire.]]

("Ok it looks like a normal family. Then I wonder why Ciel-san. said it would be a fun life.")

("Actually don't tell, I don't want spoilers of my life.")

[Okay]

Rimuru told Ciel not to tell him too much about things or life would lose its fun.Ciel as always followed his orders and did not object.

[Body ready reincarnation started].

........

When I opened my eyes I saw a hospital room. I was expecting this since I was going to be reincarnated as a baby.

The strange thing was that I heard a baby that was not me crying. I didn't even have time to look around as I felt it patting me on the back "would that be the time I cry?" I thought and started to act out a cry.

"Buaaa buaaa buaaa!"

I made the best fake cry I could so they wouldn't think I was a weird baby. Meanwhile I heard my new parents talking.

"Honey it's two boys just like I said it would be. Since I got it right, they will be the names I chose, okay? Do you want to hold them?"

"Yes!"

As I suspected the other cry was from my twin brother, my parents seemed to have gambled with our birth, which makes me realize that this family may not be as normal as I thought. I was still staging the cry when the doctor placed me in my mother's arms. I looked at her, analyzing her appearance.

"Hi, you'll be called Rimuru from now on. You're so beautiful, so cute, and those beautiful eyes.... Golden?"

My brother's name is Hajime and mine is Rimuru. Ciel must have done something for my name to be the same, probably some kind of mental induction.

I decided to keep the same appearance so my mother was quite surprised by my golden eyes. She will probably freak out when my blue hair starts to grow. I hope they don't think I am some kind of alien baby.

And so my new life began.

***

So hey guys This my First Fan-Fic and also I'm just continuing an already existing work so in a few chapter I will be making a few changes that I will thing can fit to the story I'm not sure if I'll add the lewd stuff but I'll try my best.

Monday.

The worst day of the week. Many people sighed at the thought of that day and this young man was no exception.

Nagumo Hajime was an ordinary young man who hated school as a dark place that let him down.

TREEGON

As always when the bell rang, he crept into the classroom, opened the door and walked in.

At that moment several students clicked their tongues and looked at him with contempt. The female students didn't show any friendly expression either.

Hajime tried to ignore them and sat down in his seat, but as usual, there was a nosy chatter behind him.

"Oi oi otaku disgusting! You played all night again...were those erotic games?"

"Ewww, so gross. Erotic games all night, shame on you."

("Is it really that funny to laugh?") Hajime thought angrily.

The first to ridicule hajime was Hiyama Daisuke. He was the first to pick on Hajime every day as if he was paid for it and the other idiots next to him were Saito Yoshiki, Kondo Reichi and Nakano Shinji. They were that group of Bullys that you see in any movie or manga.

This gang was the one that offended him the most.

Hajime was indeed an otaku, but neither his appearance nor his attitudes were disgusting or horrible. Short hair and normal, well-groomed student clothes, it was an average appearance. People offended him out of hatred. Why did all classes hate him? The reason is simple... She.

"Good morning Nagumo-kun! late as usual. You should come early."

A female student smiled happily as she approached Hajime. Everyone who hated hajime, hated because of this girl.

Kaori Shirasaki was one of the most beautiful and perfect girls in the school always kind, treating everyone well. Always with a smile on her face and a great sense of responsibility, she took care of other people and was very mature for a high school girl.

She was considered a goddess by the boys at school, but to Hajime she was the devil himself!

She talked more with Hajime than with the other students, which implied that she was interested in him. Hajime didn't think so, there was no reason for the perfect school girl to like him.

Hajime had average looks and grades, was not popular and was known as an otaku, which made all the students feel envious and think "Why this guy!

The students just thought that Kaori was wasting her time with him and could get someone better. That's why they didn't cast any positive glances at Hajime either.

"Good morning Shirasaki-san."

("Where did that murderous intent come from!?") Hajime could only smile falsely as everyone looked at him with contempt.

After hearing his good morning, Kaori showed a happy expression ("Why are you so happy!?")Hajime wanted to ask, but that would cause the students' assasin intent to double.

Even Hajime didn't know why Kaori cared so much about him. Not least because Kaori was always surrounded by kittens and there was no way she could be interested in him.

Then, lucky for Hajime, 3 more people arrived who would only make the situation worse.

"Good morning Nagumo-kun. Isn't it hard to deal with this every day?"

"Kaori taking care of him again? Really Kaori is very kind."

"This guy is useless no matter what you tell him."

The girl who greeted him was Shizuku Yaegashi. A beautiful girl who wore a long ponytail that was her trademark, she was another of the school goddesses.

She was considered an elegant girl, her posture and behavior were associated with the samurai, and her family had a kendo dojo in which she participated. Many girls idolized her and called her "Onee-sama". Shizuku even had a fan club.

Shizuku was one of the only people in the room who didn't hate Hajime. She was Kaori's best friend, and unlike Kaori, who was an airhead. Shizuku understood what Hajime was going through and was trying to help.

Next to her who spoke with an arrogant tone was Amanogawa Kouki: excellent grades, a superman who was great at sports, kind to everyone and had a strong sense of justice (he got angry easily).

He was a national level Yaegashi dojo athlete, as was his childhood friend Shizuku. Several girls fall in love with him, but many don't confess because he is always with Kaori and Shizuku.

The other one who mocks Hajime is Sakagami Ryutaru. Best friend of kouki, he was part of the karate dojo, was very muscular and not that smart, which caused many to classify him as muscle-brain.

"Good morning Yaegashi-san, Sakagami-kun, Amanogawa-kun is what they say 'you reap what you plant', there is no way."

Hajime spoke up and gave a wry smile. "Who gave you the right to talk to Yaegashi-san? I'll kill you!" was the feeling Hajime got from the classroom.

Kouki warned Hajime not to take advantage of Kaori's kindness. Hajime really didn't want Kaori's kindness, but Hajime couldn't argue with Kouki because it would piss off his fans and also Kouki was too short tempered.

"Kouki-kun what are you saying I was just talking to Nagumo-kun."

sigh[...seriously Kaori is too kind]."

The classroom was bursting with assasine intent directed at just one person and then the door opened to enter another source of trouble.

"Yoo, Hajime-kun and staff, sorry I'm late."

Nagumo Rimuru, Hajime's twin brother. Long blue hair, golden eyes and had a beautiful appearance, but his appearance was also a bit androgynous. Which made many students think that he was also one of the school goddesses.

He was intelligent, handsome, great at sports, the only person in the Dojo Yeagashi who had beaten Shizuku several times. He was the kind of person who made others say to Hajime "Why aren't you more like your brother?" Hajime didn't hate his brother though, because his brother doesn't like it when they say that phrase either, he is also an otaku like Hajime and they played a lot of games together. Even though he is popular he doesn't get along well with Kouki which makes some people dislike him.

Hajime didn't even have to ask why Rimuru didn't like Koukir because he already knew. Kouki was really annoying.

One thing that always confused Hajime was Rimuru's blue hair and golden eyes. Hajime had never heard of another person who had that hair color and all-natural eyes.

Hajime once asked his mother if Rimuru's hair was ever examined by a doctor, but she replied "Of course not! If we do that, the government will come and take Rimuru away! Then the scientists will do various experiments on him!"

Hajime thought that was an exaggeration, but that wasn't such a big deal. The other day Hajime asked his brother if he knew anything about it, and he denied it.

Rimuru once told the class that he was also an otaku, but no one believed him. They thought he said it just to improve Hajime's reputation. It was as if he was saying, "Popular people can also be otakus."

A lot of the murderous intent dispersed and many people who were looking at me looked away, this was due to an incident that happened a while ago when Hajime was suffering a daily beating from Hiyama's gang.

Rimuru interrupted and asked them to leave gently, but Kondo said something like "Get out of here or we'll beat you up too. His gentle smile turned into an expressionless stare as if he was looking at an insect so he hit the four Bullys and didn't get a scratch. That incident happened on the way out of school. So many people saw it and so the class was a little afraid of him.

After that day Hajime asked him not to interfere anymore because it would make things worse, with people saying things like "He's a coward who needs his brother to protect himself.

Then Rimuru sat back in his seat, stretched out in his chair and let out a bomb.

"Wow, those two flirting again..."

He spoke in a natural tone and Hajime thought ("You couldn't have kept quiet!?") That's because when Rimuru uttered these words, the temperature in the room dropped and the envious glances increased by a lot.

Shizuku laughed at the statement. She and Rimuru were quite good friends, as Rimuru had been part of her dojo since she was a child. Kaori was also good friends with Rimuru, and upon hearing his words....

"O...what are you talking about Rimuru-kun...I just...I was just talking to Nagumo-kun!"

She looked at Hajime and blushed, then looked away and returned to her seat. Hajime could hear several tongues click in disgust.

By the way he and Kaori were not that close the reason she called him by his first name was because Hajime and Rimuru were in the same class so if someone called "Nagumo" it could be confusing so he asked everyone to call him Rimuru.

The school bell rang and the teacher came in.

Maybe she was used to the atmosphere in the classroom and didn't say anything. She then started roll call.

Then the class started and Hajime slept on the desk. Meanwhile Kaori smiled seeing this scene and most of the students looked at him with disgust.

Hajime woke up at break time and grabbed his lunch box, he looked around and noticed that several students went to the cafeteria to buy snacks. So there were only 2/3 of the students in the room and teacher Hatayama Aiko.

[Swallow] [Swallow]

Hajime impressively finished his lunch in 10 seconds, then our goddess (Kaori) sat down beside Hajime with a smile on her face.

("This is terrible!!!") Hajime thought.

"Nagumo-kun why don't you come and have your snack with us?"

A dangerous aura spread through the room once more. Hajime groaned in his mind. He didn't understand Kaori's intentions, he just knew that this would not end well.

"Ahhh thanks for the invitation Shirasaki-san, but I'm done eating. Why don't you join Amanogawa and the others?"

However the goddess (who couldn't read the mood) wouldn't give up so easily.

"Eh? Was that all your snack? You have to eat more. Here take this, I'll share some of mine with you."

The chill in Hajime's spine only got worse and then more trouble arrived, Kouki."Kaori let's eat together, I won't allow someone like nagumo as your delicious

homemade food."

("How can he say that with a smile?") Hajime Thought

"Eh? Why do I need your permission?"

"Pfft"

Rimuru and Shizuku tried to control their laughter but failed miserably. That's because

Kaori said it because she really didn't understand, but what she said was totally Now the most popular students in the school

were around Hajime's table and the stares were getting worse and worse.

Hajime sighed and thought

("Please someone take them away from here").

Hajime was about to run away but before he could he stopped. Not everyone stopped and stared in

amazement at the magic circle at or feet. Rimuru was surprised by the magic circle at his feet and used his 'thought acceleration'

ability.

[Magic unidentified but by language standards it says "Summoning"]

("So we are being summoned to another world and what do you mean by unknown magic? Aren't you supposed to be the crazy one for analysis who knows everything about magic?")

[.....]

Ciel seemed a bit offended by Rimuru's words. Rimuru apologized and rephrased the question.

("Why don't you understand this magic?")

[This magic pattern is unlike that of any world we have ever visited. I can't understand it well until I do some tests].

("I see, a new world hein... It could be fun. Eh? Wait, Ciel-san, did you know that this would happen to this group and that is why you reincarnated me in this life? No, it's not possible, not even you could foresee it that far, right?")

[....]

("This silence scared me a little, but let's forget about it. The problem is that I am dealing with unknown magic. I could probably escape this circle in time but I don't know if I would be able to find my colleagues later, so I think the best action to take is to let myself be carried away.)

[Agreed.]

("If Ciel-san agrees, then let's go!")

Rimuru deactivated the thought acceleration and the magic circle glowed stronger. After that all the students disappeared from the classroom.

Bonus Story:

Back in Tempest

Two Figure Can be Seen on a dining table Arguing about something.

"Brother Please Eat Your Vegetables!"said by a Girl named Shuna

"I told you anything but Carrots"replied by Benimaru

"Please Eat It or I'm Gonna Force those Carrots in to your mouth"

And so Benimaru's hellish dining continuous.

Hajime closed his eyes because of the strong light from the bright circle and when he opened them, the first thing he saw was a 10-meter mural. On this mural was a blond man with a halo on his back. When Hajime looked around he saw that he was in a very well designed marble hall.

He looked at his classmates and saw that Kaori and her brother were fine. He was relieved and everyone began to assess their surroundings. Besides his colleagues there were 30 people kneeling before them.

These 30 people wore white clothes with faint blue details. The person who was closest had the most prominent clothing and clothes reminiscent of a priest, he had a staff in his right hand. This man approached and spoke

"Welcome to Tortus Hero-sama and his companions. I am Ishtar, Pope of the Church of the Eth, let us get along well from now on."

This man appeared to be 50 years old and spoke in a solemn and respectful voice while showing a gentle smile.

●●●

Rimuru was the only one who was not confused. In his world there were summoning rituals that required 30 mages or one powerful person to perform them.

But by the looks of it these didn't seem like bad people as they introduced themselves politely and didn't attempt an enslaving curse like the summoners in Rimuru's world did. Obviously there was a chance that they just didn't have knowledge of this magic.

All the students were taken to a very luxurious room with a long table that had seating for all of them.

Aiko and Kouki's group sat at the end of the table as close as possible to Pope Ishtar. Hajime sat in the last seat with Rimuru beside him.

Then the doors at the back of the room opened and beautiful maids came out and served water to the students. The pubescent boys stared at them with desire, real maids who looked like they were straight out of a movie stirred their teenage desires. Meanwhile the girls cast them cold glances.

Hajime looked at the pretty maid who served him, but then he felt a chill run down his spine from the smile Kaori was giving him and stopped staring.

Riimuru wouldn't fall into traps like that, not least because his world he was used to being served by various beauties, but more importantly he had a bride in the other world with whom he kept in touch regularly.

Eh? You want to know who the bride is? We'll talk about that later.

*Well I thing some will already know*

After this Ishtar spoke in a voice that everyone could hear.

"So I know you are confused, so let me explain..."

What Ishtar explained to them was basically is this...

This world had 3 Races, Demons, Humans and Demi-humans. These races lived separately and always clashed, the humans were outnumbered, the demons were stronger and the demi-humans were unbeatable in their territory because of their natural abilities.

The demons and humans were always at war, but none of them attacked because their strengths were balanced by numbers and strength. Magical Beasts were animals that acquired magical power, they varied in power, but having them on your side would be a great advantage in war. So with the Magical Beasts on their side, the demons now broke the numerical advantage of the humans and could attack at any time.

"That's why Eht-sama summoned you to take part in the war to save humanity from the evil demons. Because you come from another world and have passed through the barrier separating the worlds, you are much more powerful than the people of this world, you are our "salvation".

Apparently the person who told them that this was "Eht-sama's" wish was an Oraculum who could contact God. Hajime and Rimuru were suspicious of this "Will of God" and thought that Ishtar was distorting the world for her own convenience.

Rimuru even thought that it might have been Ishtar and the church that summoned them to this world and were just using the "Will of God" as an excuse, but Ciel said that Ishtar didn't tell any lies. However that doesn't mean that everything he spoke was true, these could be the things that Ishtar believed but were not necessarily the reality.

Teacher Aiko spoke after that.

"Please no jokes these children will not fight a war! I absolutely will not allow it! Send us back! This is kidnapping you know!"

Aiko was furious, she was a novice teacher and only 25 years old, but she was very responsible and on many occasions protected her students. She was furious at the unreasonable invocation and requests, but Ishtar's words made her sit up in her chair.

"Unfortunately we have no way to send all of you back to your own world."

Everyone froze, including Rimuru, normally he would be calm as he can transition between universes freely but when he thought about it Ciel spoke

[Unfortunately I can't send us back].

("What?")

[The magic that brought us to this universe is different from the magic I am used to, and there is also the factor that this universe is not connected to the other universes we have been to. The space-time laws here are different. I don't know what method was used for this invocation, but if there is a way back to our universe it will probably be with magic from this world].

("Do you have any method of contacting the people there, at least!?")

[At the moment No, the only possible thing would be to copy the magic circle seen earlier and try to summon a person from the master's universe,......but If I'm Given enough Time I can Analyze This Universe and I can Find A Way to communicate with ours].

("Then I'll leave it to you Ciel")

[You can count on me Master!]

Rimuru was thoughtful at Ciel's words, but back to the present the students were....

"What do you mean they can't send us back!? Huh!?"

"If you can summon us you can send us back right!!!?"

To those questions Ishtar answered:

"As I said, it was Eht-sama who summoned you. We have no method of sending you all back to your own world."

"That's..."

Aiko murmured before diving into her thoughts searching for a solution. She cared deeply for her students and didn't know what to do if they couldn't return to their families. Meanwhile the students were panicking and refusing to take part in a war.

Ishtar was looking at them with a calm gaze, but in that gaze some noticed contempt. He must have been thinking, "It is natural to feel honored to serve God.

At that moment Kouki banged his fist on the table and stood up, silencing the students and causing them to look at him.

"All of you, there is no reason to make such a mess in front of Ishtar-san. He hasn't done anything to us... I will fight. If the humans need help I cannot deny their request. If God summoned us to save the humans he should send us back after saving them what do you think of that Ishtar-san?"

"Right, Ehit-sama will fulfill the request of his saviors."

Kouki spoke words full of 'justice', but he didn't realize how naive his words were. Ishtar seemed happy with his agreement.

"Right then I will use this new power to fight and save the world, you will see!"

Kouki said confidently.

"I thought you were going to say something like that, if you go alone it will be dangerous. I'm going to fight too."

"We have no other choice, even if I don't like it I'll fight too."

"Shizuku..."

"Err...If Shizuku-chan is going I'm going too."

"Kaori..."

And so with the most popular students in the class deciding this in this display of charisma the other students agreed as well.

("Eh? Are They Idiot!,They do know what war is, don't they?") Rimuru thought. He looked at his brother who had his hand on his forehead and was looking down. Rimuru could understand what Hajime was thinking. It was "What are these idiots talking about!"

Aiko tried to convince them not to go to war, but was unsuccessful.

●●●

After the students decided to participate in the war they needed combat and magic training, or it wouldn't be impossible for them to face magical Beasts and Demons all of a sudden.

They also found out that the kingdom they were in was the Hairihi Kingdom which had a great relationship with the church as it was rumored that the founder of the kingdom was a descendant of the God Eht.

Before the training they were going to the "Mountain of God" which is the highest mountain in the world, similar in height to Everest. They passed through a magic portal that took them there in a second. Seeing magic for the first time amazed them.

On top of God's Mountain you could see the entire capital of the Hairihi Kingdom. It had a castle that stood out in the middle of the city, another highlight goes to the several churches that could be seen.

This country reminded Hajime of pre-war Japan in the days when religion and politics went hand in hand. It was horrible.

●●●

After visiting the kingdom, they went to the palace to introduce themselves to the royal family. There they passed several people who worked in the castle (knights, chambermaids, etc.) all of whom looked at them with respectful eyes as if to say "You are the Apostles of God!" which made them very uncomfortable.

In the throne room there was a middle aged man sitting on the throne and a woman of similar age beside him. These were King Eric and Queen Luluaria. The King and Queen treated them super respectfully because they were 'Apostles of God' and it made them super uncomfortable.

Behind the thrones was Prince Randel, a young blond boy of 10 and Princess Liliana, a beautiful young girl of 15 with hair the same color as her brother

Liliana chatted with them quite a bit, but Randell chatted only with Kaori. In fact he seemed more like he was wooing her. It seemed that Kaori's charm worked even in this world. The students kept casting envious glances at Randell, but Hajime thought they were exaggerating. There was no way Kaori could fall in love with a 10-year-old boy.

Some of the students like Rimuru, Hajime and Shizuku noticed that the King was very respectful to Pope Ishtar, showing once again the influence of the church in the Kingdom.

Then they had a delicious meal that was very similar to western foods on Earth. When they finished the meal they were taken to their rooms.

They were once again uncomfortable as their rooms were very luxurious, but the people of the Kingdom insisted on these rooms. So the students who had had enough surprise for one day lay down on their fancy beds and fell asleep.
