Hello, folks! Welcome to my trashy self-insert fanfiction that will containt many crossovers fandom and will be a Multiverse. I think this is my first time to write in fanfiction and sorry if my story is trash, bad and worse. Like my grammar too, I really need a beta to do the beta for my grammar, to fix my mistakes.

Well, this story will be Mass Harem? Lemon? Maybe, but if you don't like it, just leave okay, don't make a fuss about this!

I don't own High School DxD or others!

Chapter 01 - My life becomes... amazing?!

Tiring. That's one thing I can think of. I could only sigh heavily because of exhaustion with my lecture from morning till now. Indeed, on Wednesday, the schedule is so crowded and until late at night.

Right. At 17:30 I just came home, with a body of exhaustion and felt that there was no energy left, both of my feet stepped up and took me to the route where I used to go every day and every day. Where to go? Of course, to my boarding room, to rest with a relaxed sleep because there are possible tasks waiting for me and can't sleep if it's not time.

Occasionally, I open and play my cellphone, even though I'm on the road and don't pay attention to the road. What's great doesn't make me hit or get hit by something. Maybe this is one of my hidden talents (?).

After walking about 5-8 minutes (the distance is not so far, between campus and my boarding house), I finally arrived in front of my room, which made me rather happy and was relieved when I opened the door until I heard—

"Ah, welcome, Ondra."

A voice that sounds no emotion. Feels empty. The empy look of her black eyes, the long beautiful black hair, the cute and a face the size of a small child. She was a figure I knew, a girl I knew and might never be able to meet.

Because... because... the one in front of me now is—

"Ophis?!"

She put on a confused look when she heard my words.

"Yes?"

"Why are you here?"

"Can't I?"

"No, no! You can but... how can you be here? You know, that you are—"

Before completing my words, suddenly Ophis gave me a letter. This made me curious and accepted it, tried to open and read what letter and from whom made me raise my eyebrows in confusion.

"Ahem. 'Greeting, young man. You must know me, right? If not, try searching on the internet and you will know. My name is Kischur Zelretch Schweinorg! The fourth position of the 27 Death Apostle Ancestor, which can be known as the Wizard Marshall, Kaleidoscope, one of the five wizards who have True Magic, has magic called Kaleidoscope!'."

Zelretch, so it's him...

Then I continued reading it.

"'Take it easy. I know that you always long for this, which is to hope the characters from the various dimensions and series that you follow become real, especially what you call waifu. Hehehe. Don't worry, I give you the True Magic Kaleidoscope, but unlike mine—it's allow you to take someone from the Multiverse to your world. Interesting right? Ah, not only Ophis will come to your world, but others as well. '"

What is this, a shounen?

"'And, don't think your life will be calm and peaceful as usual. With you who already has Kaleidoscope and people who come from the Multiverse, your world will not be the same again and you must change your perspective. Maybe later you have to do battle and more. Who knows? Oh, too long? I remind you again, you don't have the power of 'The Gamers' but because of the Kaleidoscope, you can learn Magecraft and Magic, so... good luck!'"

That is all. I read all the contents of the letter. It made me speechless and squeezed roughly the letter. I don't know that I have to feel angry or happy. Happy because you can meet fictional characters I like, especially fiction and angry because my life has changed drastically.

"Ondra...? Are you okay?"

I smiled and shook my head while stroking Ophis head.

"—no. I... I feel... I don't know, I'm confused."

This really makes me confused. Why is it easy for the vampire to change my life just by... bringing waifus and giving me True Magic...? I mean... maybe the majority of weebs will be happy and don't care about that but this... really makes me confused.

On the one hand, I'm happy but on the other, I feel... angry.

I don't have the power like 'The Gamers', that's what Zelretch said. Certainly, because I didn't see any names and levels floating above Ophis's head. But to be sure, I tried to say 'Status', but nothing appeared.

With Ophis in here, can I have a Sacred Gear? I don't know, even though I don't have one, I hope to learn magic and Magecraft. But for that problem...

"Where will I study Magecraft...?"

I'm not even sure of the information provided on the Type-Moon Wikipedia about Magecraft. I'm not a big fan of the Fate series, I'm not even addicted to playing Fate/Grand Order like everyone else.

Ophis teaches me Magecraft? Impossible. If it's magic, I think it can even though she is a dragon and also... wait a minute, is she—

"Ophis! I want to ask you something."

"What is that, Ondra?"

"Can you make this room soundproof?"

"Mn."

Nodding understanding, she stretched out both of her hands and I could see a layer of black aura covering the whole of my room. It surprised me, amazed to see something like that. Magic! That is completely beyond human reason.

After making sure that my room was soundproof, I nodded and put on a serious look while looking at Ophis.

"Do you have gender or not?"

I know. This is the stupidest question ever heard but from what I know, Ophis is genderless, even though it has the form of a cute girl in her own dimension, DxD, but this really makes me curious. Maybe there is some kind of change from her.

"Want to see it, Ondra?"

She asked me that, with her innocent and expressionless gaze, holding her bloomers, she seemed to be trying to pull it and then she pulling down her bloomers. That made me even more excited and nodded at her.

"Right. I just want to make sure."

Okay, I'm perverted and will be told pedo if I see the genitals of a little girl like Ophis. Although in fact she was thousands of years old, older than me but her attitude and appearance were really like a little girl in general.

Yes, I don't think it's wrong, because she is really innocent—not having any experience, even when offering me this. She really is like a soulless container but I'm sure she still has a soul, it's just that her personality isn't formed and is still empty.

After all, she is one of the Dragon Gods, the Ouroboros Dragon who has the nickname Infinite Dragon or Nothingness Dragon. Its power is emptiness, just as the power of Azuma Kazui, the main character from LN I currently write.

Without hesitation, Ophis immediately pulling down her bloomer and made me see it. Right, I can clearly see the her genitals and, as I thought, she is a woman here. Oh wow, this is truly amazing.

Zelretch, thank you! You have granted one of my wishes! Banzai!

Feeling satisfied with that, I told Ophis to lower her hand and there was one thing that made me curious too.

"Ophis, how can I and you understand each other? I mean... can you understand each other's words?"

Right. Language. That's what I was afraid, for me at this time she spoke using Indonesian fluently but somehow for Ophis, it is possible that I sounded speaking using Japanese fluently to her.

Is there some kind of auto magic translator? Like in Zero no Tsukaima? Where is Louise who should spell Saito with a spell to shut him up but instead has the opposite effect that allows him to understand all the words and speak of Halkegenia people?

What is the cause because Ophis is in this world, so she can automatically speak Indonesian? But it's impossible right, this is not a lame story like that and I doubt that, even Isekai like Zero no Tsukaima just has to use a magic spell so he can talk and hear Halkegenia people.

"I don't know, Ondra."

I knew it.

I could only sigh because I got an answer that didn't satisfy me. Wanting to ask Zelretch but I don't know how to contact him, he just sent me a letter with greetings and just a little information to me through Ophis.

Will there be another, another character from the my waifu in here? Will they like me? I don't think so.

Bitter reality. Even though there are waifu or husbando that become real, not necessarily they like you. It's possible to see you disgusted and low because you are in the same level with the otaku in Japan there.

But hey, at least with a dramatic change in life now, I should be able to do it. Even though I doubt it because it was once said to be fuckin dense like the main character of a harem by my friends, but what can I do—that's me.

I'm not even sure my life has suddenly become a romcom harem genre. That really doesn't make sense, it's impossible but yes... there's nothing wrong with hope. Yeah.

"Okay. Ophis, can you read this?"

I show her the piece from the LN dialogue that has been translated into Indonesian. The response given by her? She nodded, made me amazed and nodded understanding but there was one thing that made me weird.

The letter.

I just realized that the letter given by Ophis was in Indonesian. How can Zelretch write it? That really makes me confused, ah, but because he's Wizard Marshall so I think he has learned languages from various countries and dimensions.

Such troublesome old man.

I can only sigh heavily. I felt a heavy burden now, making both my shoulders feel a bit stiff and heavy.

"Ophis, can you teach me about magic?"

I want to be able to use it. Even though I prefer alchemy, it's okay.

She seemed to put on a confused expression by tilting her head cutely. Damn, I can get diabetes because of the level of the cuteness now. I must resist, at least prioritize other things than lust.

"For what, Ondra?"

"Well... to ease the burden of my life? Like there is a possibility that I can meet and fight the anomaly mentioned in Zelretch's letter earlier. Because I don't think it's possible my life will run so smoothly without any obstacles that's waiting."

It's not that I'm masochistic, but living without a challenge feels boring. Especially if everything you want can be easily obtained. What is the purpose of your life then? Empty, no deep meaning and can make yourself interested.

Of course not always fantasy things like magic and others are interesting. Especially if I am called to Isekai and must be a hero in order to defeat the demon king who will make me go back to the normal and boring world.

Maybe it's the best. Normal. Peace.

But I don't think my life will be like that anymore. How do I explain this? I could be jailed because I thought I kidnapped children and hid them in my boarding room. I must ensure this.

"Ophis, I know this looks cheating, can you give me your power through your snake? And make people in this city think that existence and whatever we do is normal and understandable?"

I'm really the worst. AAAAAAAAAAAAAAAAAAAAAAAAAA! This is really like the plot of an erodoujin that I often read, I mean... what I want from an innocent dragon in front of me that turns out to be a loli and a real woman!

Oh Gaim, forgive your servant.

[It's okay, Ondra. I forgive you.]

Hah?! Where did it come from?!

Suddenly, I could hear the sound of Kouta, but I ignored it because it might just be my imagination because I always rewatch Kamen Rider Gaim that often impressed me and was addicted to it.

Indeed. It seems like too much watching Kamen Rider Gaim can make me listen to Kouta's voice. But what can I do, I like the series. It's completely different from the others because it was made from Gen Urobuchi the Character Killer.

But what I saw, Ophis nodded her head. She said yes? This is truly amazing! Banzai, Ophis! You're the best girl!

"Yeah, sure. Here."

She reached out her hand, which made me think to extend my hand too and immediately I felt a kind of sting that spread from my hand as it touched Ophis's hand. It was as if there was electricity flowing in my arms, making me sick but trying to resist.

Shit...! Is this the feeling of getting a real power? The power of magic that has been fiction all this time? Especially that of a dragon god like her. This made me like Izuku who got One For All from All Might after 10 months of training.

I removed my grip on her hand, trying to move my hand to check if everything was fine. For a few minutes, it turned out to be okay and made me sigh with relief, then I looked back at Ophis.

She nodded, her hands stretched out, again I could see a layer of black aura spreading out somewhere, my assumption might have surrounded the city of Bandung that I now live in. Well, maybe she issued a magic spell like my request earlier.

"What was that spell now, Ophis?"

"Like, your request, Ondra."

Ah, as I thought. She really did it. Even though I don't think she obeyed someone, but why did she become obedient and obey my will? Is she Ophis who is on my fanfict? Who obeys Kazui's will? If so, I'm really lucky.

Haha, has been given Kaleidoscope, waifu (possibility) will be in the real world and also can and get strong magic for free from the girl like her. Moreover, the one who gave it was the dragon loli god, one of my favorite girls.

As Kiryu Sento said: "Great, right? Amazing, right? Genius, right? "

I really have to prepare everything, for the bad possibility that will happen later.
