DxD: A New Beginning

"... What?"

I found myself suddenly yelling. I'm not sure what's going on, but I suddenly feel like something inside of me has changed. No, what the hell happened? My thought process abruptly brought me to a halt.

"What's the matter, Kanata?"

"No, no, It's nothing much, sis."

"You're really strange, Kanata."

I came to a halt, and the giggling little girl gently drew my hand away. I was taken aback by such an act, which I had previously taken for granted.

I had no idea why this little girl was pulling my hand - no, she's my sister. Given my age, it was only natural for her to take my hand in hers. That's when my thoughts came to a halt once more.

I couldn't understand my impatience. Fear. I'm not sure why I'm feeling this way, but I'm also not sure why I'm complaining that this is the normal state of affairs.

Even the height of my gaze as I walked down the street and it made me uneasy. I had the impression that my own eyes were higher than that.

"Was my name Tanaka, sis?"

"What do you mean, about that question?"

"Yes, Aimi Toga , I'm your sister, and Tanaka is my brother."

"... What age are you?"

"What exactly is going on? I'm eleven years old, and Tanaka is four years younger than me, so he's seven."

"Did you have any siblings?" "Like a big brother?"

"Tanaka is so strange! Mom, Dad, me, and Tanaka, we're a four-person family, right? Or are you saying that you would have preferred a big brother over a big sister?"

I hurriedly responded to my sister's vehement denial. I'm at a loss for what to do. Yes, I recognize her. I'm not sure what to think about it. So why do I feel so uneasy about it?

What is the reason I don't have a sister? Why do I have the impression that I should have had an older brother? Since the day I was born, my sister has been by my side.

I recall everything from the previous seven years. Of course, there are many things I don't remember before kindergarten.

"I'm not sure how I was able to think so clearly in the first place."

Seven years old is most likely in first or second grade. My mother seemed to be laughing and using my brother and I's old story to tell me that children of that age were aliens. Wait, wait.

... So, what's the story with that memory? I'm not sure if I'll be able to participate in that. I'm not sure what to think about this. I have knowledge within me that Tanaka should never have had. That fact sent shivers down my spine.

"Are you all right, Tanaka?"

"Nothing's wrong with me. I'm fine, but when I get home, I'm going to rest."

"All right, I'll tell our mother."

You're a wonderful big sister. You're not like your idiot brother, who dragged you out to play soccer with a bunch of people despite being tired.

...once more. It's a good idea to understand what you're doing. It's a good idea to know exactly what you're looking for.

"Wasn't it the Kamakura Shogunate's motto, 'Let us make a good country?' No, I assumed it had changed. That's why I don't know why there have been so many large earthquakes and disasters in the modern era.

How did I, a seven-year-old, learn about the Kamakura Shogunate and modern disasters?

I sat on my bed and flipped through a section of my sister's history textbook while she was not in the room.

It was the first time I'd ever seen the contents of a textbook, but I had the feeling I'd seen it somewhere before.

Before yesterday, this had never happened to me. On my way home from school, something had happened to me. There's no denying it.

There was a mismatch between the age I knew and the disaster I didn't know about. I also borrowed my sister's math textbook, which made me nostalgic for some reason.

I attempted to solve the problems in the textbook half-heartedly, using the back of the origami paper I had on hand and the fact that I could solve them. Needless to say, I became even more perplexed.

"First and foremost, it's strange that I can read a history textbook. There are many kanji that I have yet to learn. And yet, i believe i understand how to read it and what it means..."

It's unsettling. That was my honest reaction. I thought I was a genius! I'm sure I'd feel better if I could have declared, "I'm a genius!" It is undeniably convenient. But, more importantly, I am aware that this is an unusual situation.

I understand. I'm not sure what I'm going to do, but I'm going to do it anyway.

"... Well, the most unpleasant thing appears to be inside my body."

My hand gently strokes my chest. The head was one thing, but the most unsettling sensation came from within my own body. The more I settled in, the more uneasy I became.

This was unmistakably my own body. However, I had the impression that there was a foreign object inside that was distinct from it. That was the most unsettling part for me.

I just want to get rid of it. I reasoned that if I did so, this perplexing situation would be slightly improved. But, as expected, I am unable to vomit in the room I share with my sister.

It would cause her concern, and as a man, I don't want her to see me in that light. That's all! I rose from my bed.

"Tanaka, Tanaka Are you all right now?

"Yes, sis. Now that I'm feeling a little better, I'm going outside to freshen up."

As I walked out of the room and down the stairs, I ran into my sister, who had a worried expression on her face. I couldn't really say I was going to puke outside.

"Do you want me to accompany you?"

"No, because male dignity is at stake."

"Son-...? Is it significant?"

"Yes, it is essential for a man."

"Oh, I see what you mean. It's known as puberty. That's right!"

Puberty is a fantastic word. My age is only seven years. And are you sure you're okay with that, sister?

"Well, then, I'm off."

"Yes, you must return by five o'clock. Also, it is a Kuramoto family rule that you must tell us where you are going."

"That's correct, hahaha. A small open space surrounded by trees is located near the factory. I'm going to that place."

"It's a place where few people go. It's a place that few people visit because it's almost completely unspoiled."

"I just want to relax and look at the sky for a change in an empty place like that."

"Hmmm... Scream at the top of your lungs if something bad happens to you. If something truly horrible occurs, you must scream and flee. Do you see what I mean?"

"Yes, I do."

I thought she was worried, but I also smiled at her efforts to be a good sister. I'm not sure what to make of this, but it's probably a good idea.

I climbed onto the bike I'd left by the side of the house, shrugging my shoulders at my arrogant thoughts.

I'd been to the plaza a few times before, so I was confident I could find my way around. With a map in my head, I concentrated all of my energy on the pedals.

Tanaka Kushimoto is a second-grader at an elementary school. I'm seven years old right now. I'm going to refresh myself.
