The Prohibited Isekai Life of a Certain Transmigrating Brother and Sister

Me and Ceres' previous lives have been quite spectacular and miserable.

In my previous life, I was the moon castle and Celeste was the moon castle.

We were born into a wealthy house there, and at first glance from the side, we would have looked like children living without freedom.

But the reality is terrible... we twins have spent our days frightened by a good DV temperamental father and a neglected, hysterical mother on the outside.

The school teacher should have noticed abnormally when he saw the unnatural mole in my body, but no one, as one, reported the facts of the abuse because he feared his father, who was in power.

In that, I was like, "If I didn't protect Thousand Cranes," as a child.

My father tried to dissipate by punching us in the face of stress. By taking such a defiant attitude towards my father, I dared to direct the spearhead of violence towards me.

Now we were able to protect Thousand Cranes, at least from physical damage. And by then, I was already thinking, "My mission is to protect her."

Because we grew up in such an environment, our sisters and brothers turned to nature and gradually only believed in each other.

One day, my parents died in an accident. As if the heavenly punishment had fallen. We were twelve years old. My aunt and I were to be picked up by an aunt and a wife we hardly ever met.

But the couple were also indifferent people to children whose violence was what they didn't wield. As a result, I think our bonds have grown deeper and deeper.

After I graduated from elementary school safely and went to middle school, I and Chizuru gradually remembered less of my demonic parents.

Has it been since then? Because I could afford some space in my heart, I felt my love for Chizuru, which I had held for a long time, deepened.

I'm sure that since that day when I decided to "protect Chizuru," I've come to love her as one woman, not my sister.

Chizuru used to say this. "Hope is the 'light' that illuminates me. Whenever it's hard, it helps. I'm the only prince," he said.

I thought when I heard it. From now on, I'm trying to live to protect her smile. As she tells me I'm a light, Chizuru was like an angel, a goddess, that healed herself to me... such a being.

In fact, I was glad that Chizuru relied on me, and that was worth living for. I've worked hard to support that word.

I should have stayed with Thousand Cranes, and I didn't need anything else. She also told me that I was "my favorite," and she also said, "I want you to stay by my side the whole time."

It's just... I really couldn't just convey the thoughts I had on my chest.

As I grew up, I realized that the emotion I had for her was' something I shouldn't do '- because I understood it was a thought that should never be known around me, that I had to hide.

Chizuru, who became a junior high school student, became interested in the heterosexuality around him.

The young new teacher in charge looks good, and there are handsome boys in the same class... Whenever they ask me about that, they say that my "likes" and Chizuru's "likes" mean something completely different... to her, I was reminded that I would never be a paedophile.

My thoughts will never come true. Unlike the men around Chizuru, you are not even allowed to stand on a one-sided starting line.

The fact kept me in pain for years. But still, I was glad she needed me in any way.

The two of us will support each other, lean in and live - I always thought those days would continue.

High school freshman summer.

It was after school one day. Talking in the hallway with Chizuru, suddenly she was summoned by one male student.

I'm in a different class than Chizuru, so I don't even grasp the faces of students in the same class as her, but I'm probably a classmate.

The boy student tells Chizuru something even though he cares when he sees me a little further away. At the next moment, Chizuru bowed his head and apologized to him. Seeing that exchange, I immediately guessed, "Oh, a confession?"

Apparently, haste meant backwards he was shaken by a thousand cranes. Driven by jealousy, I gently glanced at the male student who tried to walk away across his side with the meaning of restraint.

"Hey, I'm shaken. Sure, it's your brother, isn't it?

"... Yep. Yes, but."

Apparently, he knows about me.

"I envy you for having such a lovely sister close to me."

That was the last word I wanted to be told.

Only appearance resembles good parents, and we twins are often praised for our appearance by others.

Chizuru, who became a high school student, had grown into a girl who was somewhere frivolous but full of truthful atmosphere. With bright dark hair stretched up to her back on her big black eyes, she was a beautiful girl to the extent that she had a hidden fan, though seemingly inconspicuous.

So from the mouthfeel. Perhaps this man liked the contents of Chizuru just because of his appearance, without even knowing them very well.

This man, to that extent, has a better chance of being tied to her than I do. All I can say is sarcasm.

"Nothing... you don't know..."

"What?"

I let him whisper so whispering, even though I gave him a full grumpy attitude. You didn't hear me, he peered into my face leaning down and asked back wondering.

"From me, I envy you more."

…… What do you mean... "

He tilted his neck when he said "I don't know what you're trying to say". But his reaction is normal. You can't imagine I really like her, my real sister.

But this man...... what are you talking about as much as being shaken once?

─ ─ Aren't you Chizuru and others? Then there's a chance, no matter how much. I mean 'no blood ties' with her...... I envy you just for that.

If I were this man, I would confess to Chizuru more than once. I will spare no effort to do so, and I will try to help you turn around.

Even though I love Chizuru more than anyone else, I am her brother and therefore cannot even convey favors.

How many times have you cursed this body with the same blood as her? How many times have you wished to be reborn as someone else with no blood connection?

Looking at the boys students with that in mind, he looked suspicious and said, "Well, here I am," and left with his back turned around.

"Did they confess?

That's what I asked Chizuru, who came back with a slightly awkward look.

"Oh, yeah. I said no, though. I have someone I like…"

"Someone you like......?

"Yeah."

As soon as I heard that, it got dark in front of me. I was prepared to think that one day such a day would come. However, it is actually harder than I imagined when I heard it from my own mouth.

"The other guy...?

"I need it."

Sakuraba needs a friend - a classmate who's been hanging out with our twins since freshman year in middle school.

"Right...... Somehow, I felt that way."

"Oh, was it broken? You only have twins, and you foresee everything!

That's how I make a smile and smile back at Chizuru, who laughs innocently.

"... the prince for Chizuru is not me anymore"

He groaned so pompously as he stared behind Chizuru, who was walking a little further in his light footsteps.

"Huh? Did I say something?

"... no, nothing"

I looked at Chizuru, who turned his back again, and a deep sigh leaks.

"... don't go far"

Unexpectedly, I put it in my mouth. But she never looked back at my sad cry, scratched away by the annoying sound of a cicada.

A few months later, Chizuru and I started dating.

From then on, it was really hell. The days of jealousy went on - I finally couldn't stand it - and I passed my thoughts on to her.

And that day, we were going to run into an accident that took our lives.

My thoughts never materialized, but if I were to die with my loved ones, that was what I wanted. And yet... somehow, God gave us a second life. That too, as twin sisters and brothers again.

This world of magical supremacy, which I am sick of, was grossly similar to the world in which it was, although there is a distopian part of 'managing and enslaving people without magic', other ethics and so on.

In other words, the faint expectation that "the other world might be able to marry even if they were born as sisters and brothers" was to be beautifully betrayed.

─ ─ You're on your own to have romantic feelings for Chizuru, but don't push that feeling on her. What do you think would happen to Chizuru if he found out his real brother was looking at him like that? Worst case scenario, you're gonna break her heart.

Words that have been said in the previous life are wooden spirits over and over again in my head.

... Oh, I know. Even if you don't tell me, I've been worried about it for a long time.

Just because I was reincarnated, my memory stays the same. Chizuru's feelings won't change that easily, and you want to say there's no way you can turn around?

But even if I knew I was going to hurt you, this thought wouldn't just go away.

Maybe...... being born again as her brother is a punishment to me for loving my real sister in my previous life.

Now I am relieved inside that I was able to "gradually return the thousand cranes from the necessity" by the compulsive parting of "death". Even myself, I was amazed at how much black emotion I get.

I'm thinking about this, I'm sure I'm the subject of enough punishment from God.

But I can't help but think it's a sin to love her, my own blood relative. I'm sorry about Chizuru, but I'm not going to be able to keep my promise to "strive to get back to my normal sister and brother"......

One day, I honestly can't help but be scared when Ceres remembers that day and thinks' if they reject me 'again.

But...... Ceres was so crying and happy when we found out who each other was in this world.

So, no matter how painful I am, I'm going to let you pierce my love for her again in this world, even if I can only see her with my brother.... even against God.

There's only one wish I have - I want to be tied to her. That's all. I don't want anything else.
