C1 - I didn't go to Highschool DxD, why is Rias here!

I hope you don't mind adding this fic to your reading list too. When I read a certain fanfic, I suddenly get inspiration and I feel very eager to make that inspiration into a novel. Even though I know there are already a lot of fanfics in progress, but I can't resist making one.

And here I am, making another Highschool DxD fanfic, but this time it's different from the previous one. The concept is different, and the main characters in this book will be Rias and the male MC. There will be a switch of POV from third person and character POV, I'm also using this book to practice making character POV. So the POV in this book will not only focus on the third person POV.

By the way there will be Inner Voice and some other concepts in this book. I hope you like it and please don't misunderstand, I will also continue other fanfics, just please be patient, okay? By the way, I am also doing this to overcome my boredom in writing novels.

Anyway, that's all, happy reading, and please give me your thoughts on the first chapter in this book :)

Chapter 1

---

"Rias, I think this is a bad idea."

The short black-haired girl with glasses said to her red-haired friend, but the other party shook her head.

"No, no, Sona, I think this is a good idea."

Rias was stubborn, she was very confident in what she wanted to do, and she felt that her intuition also told her that she would not fail.

Her best friend, Sona was too worried.

As the younger sister of the strongest Maou in the underworld and the heiress of Gremory, I'm very confident right now...and I feel like I should do it.

No one can persuade me to stop, even if my elder brother Maou suddenly teleported into this room to stop me.

Just kidding, of course if that happened, the plan would have to be canceled.

Sona had an MMP face seeing that the red-haired girl was so stubborn. Do you know what you look like now, Rias? You're like a little girl excited to try out her new toy.

Looking at the shining altar with several candles in front of it, the atmosphere in the room seemed eerie like in a horror movie.

The location where they were now, was actually in the basement of Kuoh Academy. This room was originally used as a warehouse, but Rias had renovated it into a special room to do... Doing something she didn't know what it was, Sona herself was confused by what this red-haired girl was doing.

She could currently only stand still and watch Rias who was drawing a circle with an unknown language on the floor. The circle was as big as five meters, and was drawn using red paint that the girl seemed to have just bought at the store.

Wouldn't this kind of thing be more convincing if it was done with blood or something? Using red paint that resembles blood... Did you do it on purpose to deceive? Sona couldn't help but think so.

At the same time she was worried about what the red-haired girl was doing.

Judging from this summoning ritual-like scene, she roughly guessed that Rias was probably preparing a summoning ritual to summon something.

It's just that this type of summoning, she was seeing it for the first time, I mean the kind of strange symbols that Rias was drawing on the floor.

She wondered where Rias knew that strange symbol from? As an intelligent type devil who had read many books in the underworld, Sona didn't recognize the language written on the symbol that Rias was drawing, it certainly wasn't the language of devils, gods, or humans that she knew.

After Rias finished drawing, she returned to the outer side of the altar and stood beside Sona.

"So Rias, what exactly do you want to do?"

"Huh? Isn't it obvious?"

Rias tilted her head in confusion and looked at Sona as if she doubted her intelligence. Are you sure you're the intelligence-type devil?

Sona's lips twitched, she felt like hitting this red-haired girl.

Even if I know already roughly guessed what you want to do, I still went confirming it correctly!

"Look, Rias. I roughly know you want to perform a summoning ritual or something, but what exactly do you want to do? You even pulled me here instead of pulling your peerage..."

Sona said in a voice that clearly sounded like a complaint, instead of playing here, I still have a lot of student council work to do.

Unlike Rias who had plenty of free time to play every day, she, Sona Sitri was...a busy person.

Hearing Sona's question, Rias smiled and began to explain her situation.

"First, you're right that I'm going to perform a summoning ritual, and it's actually done to summon a creature. But it's not a creature from this world or universe, which means I want to summon a creature from another world!"

"What!"

Sona was stunned to hear this, before she asked. Rias continued her explanation.

"Secondly, why did I pull you here instead of my peerage? Well actually no particular reason, I just felt it would be fun to bring you here."

"Rias!"

Putting the first explanation aside, but when she heard the second explanation, she wanted to scold this hair girl.

You bastard, I thought there was a special reason why you pulled me here, but it turns out it was just because of your sudden inner desire.

Damn it.

Turning her body to the door, she prepared to exit this room.

"No, Sona! You can't leave!"

"Why?" Sona asked as she frowned at Rias holding her hands in place.

Rias saw there was hope to persuade Sona, so she quickly thought of something and said: "This... Look, isn't this interesting? You see the summoning circle I drew on the floor, you don't recognize that language, right? It's an ancient language from another world!"

"Oh? And where do you know that language from?"

Hearing this, Rias hesitated for a moment, but she decided to be honest.

"I don't know, the language and method for summoning creatures from another world suddenly appeared in my head this morning, right after I wake up sleep."

"...."

Sona took a breath, she let go of Rias' hand that was holding her and continued her journey to get out of this room.

"No! Sona, why? Woo woo, come on... Just accompany me for a while, okay? Please!"

Rias blocked Sona's path and looked at her with a puppy dog stare.

Sona sighed, she massaged her forehead before saying: "Alright, but only for a while because I still have a lot of work at the student council."

Workaholic! Rias couldn't help but retort in her heart, of course only in her heart. On the surface she made a cheerful expression on her face.

"Thank you Sona! Then, let's go... I'll show you the summoning spell from the other world."

"Yes, yes, hurry up."

Sona said flatly, and followed the red-haired girl again.

...

[Rias's POV]

Seeing that Sona was successfully persuaded to stay, I was happy and continued with what I wanted to do.

Stepping slightly into the circle I had drawn on the altar, I was actually a little nervous, but I felt something pushing me to do so.

It was probably for this reason that the information on how to summon creatures from the other world suddenly popped into my head this morning.

There must be someone who wants me to do this and although I know it's suspicious, I feel that it's harmless, rather I feel that what I'm about to do is very important as if it will have an impact on my future.

So instead of not doing it where I could have missed my chance, I felt it was better to do it and bet on my luck.

For some reason I felt a gacha sensation when I was about to summon this otherworldly creature.

Taking a breath, I poured my magic energy on the summoning circle I stepped on, and it glowed with a crimson color that matched the color of my Power of Destruction attribute.

I brought my hands together in a position similar to someone praying, closed my eyes and began to chant the summoning spell that was in my head.

【I wrote up an alternate summoning chant.】

【I call forth into time】

【For unknown entities】

【Through wishes crystallized】

【One of the individual】

【One of the collective】

【And one of civilization】

【This is my wish.】

【As I stand upon the infallible boundary, before the brink of its destruction,】

【Take form from legend, armed to fight once more.】

【From the collapse, we will forge a path.】

【And from that path, we will carve a future.】

【Through you, I embody change.】

【And through me, you embody will.】

【To those written into legend, of Heroes and Villains,】

【from Men, from Kings, from Devils, from Gods.】

【To those who hail to heed the call】

【Come forth in duty, from desire, under will!】

Although it was my first time saying this mantra, I felt very fluent in saying it as it was clearly ingrained in my brain.

I felt the air around me lift, my hair must be swaying in the air right now, the sound around me also somehow became silent.

I could also hear Sona's voice shouting my name, but it sounded small as if the other party was very far away from me.

Huh?

Wait, what the...

Trying to open my eyes hesitantly because I'm afraid something bad has happened to me.

But when I opened my eyes, instead of seeing the creature I summoned, I myself seemed to be in another place I didn't recognize.

Damn... The summoning spell in my head clearly said that it served to summon creatures from another world, but why did it seem to be me who was summoned to another world?

Thinking of this, my body trembled, feelings of anxiety and worry beginning to engulf my heart.

Looking around me, fortunately I wasn't in a terrifying place, such as outer space, the middle of the sea, or anything like that, but I was actually in a forest with green grass and trees, and a few hundred meters ahead... I could see the sight of a city-like civilization.

Yeah, it's a city and it's not clearly visible which proves that I'm deep in a forest with a fairly high altitude.

Surprisingly in this situation I was able to analyze quite calmly, I suddenly remembered a plot in a novel where a person is transported to another world in various ways.

If it's a male character who is transported to another world, they usually have a harem protagonist template.

But if it's a female character, I'm not sure...because there aren't many Japanese authors who make stories about a woman being transported to another world. Maybe just a few and it would be an otome type of novel or something that I'm not really interested in.

"Seriously, why am I so calm right now?"

I wondered in confusion while walking randomly in the forest, feeling my physical condition, fortunately I was still wearing my school uniform and I could also still feel my magic energy.

So this makes me a little relieved in this situation. I'm not sure where I am right now, but I feel very far away from home which makes me very uncomfortable.

"Ugh... Although I'm reluctant to admit it, but am I really in another world right now?"

I wondered as I continued walking in the forest. The trees here somehow seemed taller and bigger than the usual size of trees, there were also fruits or plants that I had never seen before, which made me even stranger and more convinced that I was really in another world.

Reality continued to slap me which made it even harder for me to deny that I was in another world.

"Just... Why am I so calm!"

I couldn't stop myself from shouting, because I'm sure if it was me before, I would have been extremely panicked and scared in this situation.

However, at this moment suddenly a transparent blue screen appeared in front of my eyes and someone's voice also appeared in my head as if to answer my question.

[Ding! Congratulations, you have been selected as a user of the Character Investment System.]

[Detailed information about the system's functions or something, it will be directly transferred into your brain in a moment, host]

[And as for your question just now. I can answer that it's because you've acquired a new C-class skill called [Calm Mind] that allows you to maintain your composure to assess your current situation. You acquired this skill when you were first transferred to this world.]

"...."

Okay, this thing called a system...must be some kind of my golden finger. I'm familiar with this because in many isekai novels I've read, 8 out of 10 protagonists usually have a cheat system to help them survive in the other world.

At this moment, I suddenly felt grateful for being an otaku and having read many novels so that I knew a lot of these kinds of routines.

Also... I don't have many question marks in my head and only a few. Unlike those beta protagonists without otaku knowledge, who would be flustered and confused in this situation and even some of them would whine like an incompetents person.

I, Rias Gremory, felt proud that I was slightly better than those people, and perhaps this credit belonged mostly to the new skills I had acquired.

Actually right now a lot of new information is being added to my brain, about my system and little details about this world and the mission I need to complete if I want to return to my world. This process is similar to when I got the information of how to summon a creature from another world, uh shouldn't I say it's how to summon yourself to another world? Well someone tricked me.

Surprisingly I'm only a little angry and not really mad, right now I'm just curious about the world I'm in right now.

According to the information provided by the system, this world is indeed in a different universe from my previous universe. This world is a sword and sorcery type of world where the technological development in this world is rather backward, it's similar to the medieval European period.

There are also many races in this world which is actually not much different from my previous world. There are humans, angels, vampires, dragons, demons instead of devils like me and so on. Oh and there are also some gods in this world who basically hide somewhere and just let people worship them like a religion.

And about my system, it apparently had a function to invest in someone who would be my traveling companion. I could only choose one person and it had to be chosen carefully because that person would also help me to grow stronger and stronger along with the rewards that the system gave me every time we completed a mission together.

This was troublesome, if my peerage was here, then I would only have to choose one of them, and it would probably be Akeno since she was the most reliable in my peerage.

The figure of the girl with long black hair in a ponytail with violet eyes appeared in my mind, there were also other figures that suddenly made me miss them all.

I'm starting to miss home... Well this feeling of being in another world alone without anyone you know is starting to bother me, making me depressed and continuing to walk through the forest with my head bowed.

"By the way system, when exactly can I return to my world?"

The system in my head immediately replied, fortunately it was a female voice which made me more comfortable, although the voice was a bit monotonous. But it's better than hearing an unknown male voice inside your head.

[Host must complete your main mission with the companion you choose as the investment target.]

[Main mission: Kill all the protagonists in this world.

Time limit: None.

Mission completion reward: Travel portal between worlds, and ???]

"...."

Ouch... Although I already knew about this mission since I received the information transfer from the previous system, but when looking at it again...

I felt like I was told to become a villain character who had to embark on an adventure to kill protagonist.

Who is protagonist? That is the main character who usually has the most important role in a work of fiction. Now this system is telling me to kill such a character? Well according to information from the system, in this world there are indeed many people with the fate of the protagonist.

It's not that I mind killing, after all as a devil, especially a noble devil, I naturally have experience killing, although not often because it depends on the situation and usually the people I kill are wild devils who make trouble in Kuoh City.

But still, I feel bad about going on missions to kill people, and it seems like there are a lot of people with protagonist labels that I have to kill from now on so that I can return to my world.

[System advises the host to immediately look for people as investment targets.]

[Current investment: 0/1]

[Ding! Issuing a mission: 93 meters from the host's position there is a person who the system thinks has high potential to become an investment target. Find that person, invest in that person and make that person your traveling companion!]

[Mission completion reward: Unlock a live broadcast to the previous host world (PS: This can be used to communicate with people in the previous host world)]

"This is it!"

My gaze naturally fixed on the mission completion reward, I felt excited because with the live broadcast feature it meant that I might be able to contact Mom, Dad, Onii-sama, and my friends. Although I can't go home just yet, but at least I can contact my family.

And looking at the system-issued mission, I immediately understood, but the problem was...

"System, where exactly is the person you're referring to?"

I frowned, the system only mentioned that the person was 93 meters away from my position, which meant that the person was also somewhere in this forest.

But!

Where exactly... Can this system say it more clearly?

[Straight to the right, host.]

"Okay, I'll go there!"

After the system told me, I immediately took out my wings, on my back appeared a pair of black wings that were somewhat similar to bat wings, but not bat wings of course, they were devil wings.

Putting that aside, I was already flying straight in the direction the system pointed. From the sky, I could now see more things. This forest was vast, many trees towered high, probably more than 80 meters so I even had to fly higher to see the tops.

Apart from the trees, I can also see many plants of various colors and shapes, they look exotic and beautiful, there are also animals, some of which I'm familiar with, but there are also some that I'm not familiar with.

As expected from another world, there must be many creatures I don't recognize in this world.

40 meters...

30 meters...

I stopped in midair and immediately used [Stealth] magic to hide my presence, because several tens of meters ahead of me was a large black creature with a tail and wings.

From its shape I knew it was some kind of dragon, and the dragon was so big, it was the size of a small mountain and I was like an ant hiding on the side of the road.

Of course I was afraid of such a big creature, and couldn't help but hide behind a tree. Although as a high-class devil I was indeed strong among the same generation in my previous world, but even there I wasn't confident enough to defeat a dragon.

Dragons are superior creatures that can be said to have a higher caste than devils, in my previous world, the highest power there was even dominated by two dragons named Ophis and Great Red. The existence of those two creatures was the pinnacle of the famous powerhouses in my world, and even my older brother was not strong enough to defeat them.

Although my older brother is a Satan Class Devil, and a devil known as the strongest devil in the underworld. According to my elder brother himself, his strength was far from enough to be able to defeat either Ophis or Great Red.

And the dragon in front of me, from its aura, I could sense that it was definitely not as strong as Ophis or Great Red, but it was definitely stronger than me, because I think the dragon's power was probably at Utimate Class or above if according to the power calculation in my previous world.

"But why such a powerful creature seems to be overwhelmed against something. No, it seems to be fighting someone!"

Because I was too focused on estimating that dragon's power, I almost ignored that it was fighting. Various attacks from the dragon's claws, tail, and fire breath were thrown towards the black dot in the distance...

From this distance, I could tell that the black dot was a humanoid, similar to a human with a black robe and black hair who was fighting with the dragon using a sword in his hand.

And the thing that surprised me the most was that that human's power was strong enough to make the dragon the size of a small mountain roar in pain every time some of its scales were crushed by that human's touch.

The human also appeared to be badly injured, but he did not give up and continued to fight with the dragon. No one knew how long the two of them had been fighting, but it seemed like a long time ago, and both sides seemed to be at a stalemate, as neither could defeat the each other.

That's what I was thinking, but suddenly I saw one of the human's hands shining brightly with white light, the human dodged the dragon's claw attack that was about to hit him in midair and slid into the dragon's underbelly with the sword as a brake that was stuck into the dragon's body.

There that human placed his hand that seemed to be fully charged with magic on the dragon's abdomen and shouted as if this was his final attack.

"<Dismantling!> Die you damn lizard!!!"

White light exploded covering the dragon's entire body, even the forest a few meters away and I couldn't help but slightly close my eyes as the sight was too blinding.

Moments later, I opened my eyes and saw that the dragon the size of a small mountain was disappeared. There were only many pieces of flesh and blood in the air falling like rain...

I opened my mouth with a dumbfounded expression, as I was shocked that the dragon was blasted into minced meat by that human attack!

Without waiting any longer, I immediately flew over to approach the battle site, I was of course looking for that human because he seemed to be the person the system intended as my investment target.

Then I found him, the man was lying on the ground with a pale face and blood oozing from a large wound on his waist, it seemed like the wound was caused by the claw attack from the dragon earlier.

[Host, you must save that man immediately. He will die soon if his wound is left unattended, you must save him immediately! He is an investment target with great potential!]

The system turned out to be quite noisy, even without her urging, I knew I had to save him, especially after learning that he was the person the system was referring to.

Going down to the ground, right beside that human, looking closely, it seemed to be true that it was a man and he looked about the same age as me.

His hair was black in color, his eyelashes were quite long, his facial features were very handsome, only that it looked pitiful because of his pale skin due to lack of blood.

I squatted down and tried to carry the man. With my strength, carrying a man's body was a piece of cake for me

What was difficult was saving this man.

The only healing method I have is...

Thinking of that method made my face hot, I was a little embarrassed and hesitant, after all this was a man I had just met.

But recalling the strength this man has and his great potential mentioned by the system, and looking at his appearance that is pleasing to the eye...

I swallowed, it's fine, after all this is also for the sake of completing the mission and so that I can also have a strong companion who can accompany me on my journey to complete the main mission.

Staring at the unconscious face of the man I was carrying, I sighed and said: "You... I don't know what your name is, but I Rias Gremory will try my best to save you."

Don't know if he heard me or not while unconscious, but I just wanted to say it, and after that I immediately flew off while carrying the man in my arms somewhere.

I had to find a place that was very quiet and closed off, it would be great if it was a cave in this forest.
