In an underground training area, a teenager was swinging his sword, sweat dripping onto the floor. He was solely focused on his training, as if nothing else mattered. His lean but toned muscles moved rhythmically with the motions of his hands.
"999, 1000." After counting to a thousand, Lux took a deep breath in through his nose and exhaled slowly from his mouth. His eyes focused on the katana in his hand. He closed his eyes, and then a flash of lightning began to envelop the sword. Lux smiled at the sight.
"It's been 15 years since I came to this world. Time flies. Tomorrow is the first day of school. Starting tomorrow, things are going to get more interesting," he smiled, thinking about it.
After training, I dried off my body with a towel, then headed to the fridge for cold water to quench my thirst after the workout. Afterward, I turned on the TV to watch the news and sat on the sofa.
"Today's news, a group of explorers has discovered a Devil Fruit after returning from the demon zone. The type of Devil Fruit is still unknown," hearing the news, I couldn't help but smile.
"Devil Fruits in this world are extremely rare. Only a few people can become Devil Fruit users. But hearing the word 'Devil Fruit' in this world feels strange. This isn't a world of pirates," Lux stood up from the sofa and headed to the bathroom.
In the bathroom, I looked at my face in the mirror—black hair, purple eyes, and fair skin. I gave a faint smile, admiring myself. "A man has to be confident," I muttered, continuing to gaze at my reflection.
'This world has Devil Fruits, Haki, and Rokushiki as weapons to fight demons in the demon zone. Ninety years ago, when the Abyss gate opened, hordes of demons attacked humanity,' I thought, recalling the history I'd read in books.
"That was the history of the demon era, 90 years ago, basic knowledge in this world. During that time of despair, a man with a katana in his right hand and wearing a disheveled kimono killed many demons. Despite his ragged appearance, to humans at the time, he was seen as a hero, a symbol of resistance. After that, many other humans fought for their survival," I pondered while heading to the bathtub, ready to clean off the sweat after training all day.
"Fujimasa Hojo, from the Hojo clan with a long history as samurai, led the resistance at the start of the Abyss invasion. The Hojo clan had great influence back then, until a child born with the power of a natural disaster arrived, a baby wrapped in flames. People thought of him as a demon child. However, as he grew, he learned to control his powers and contributed greatly to the resistance against the demon invasion," I thought, eyes still closed as my body rested in the tub.
When I opened my eyes, lightning sparked from my body, slithering like a snake. The water in the tub sizzled from the heat. "After the flame child was born, four other children with similar powers were born, though with different abilities. I am the sixth person to be born naturally with Devil Fruit powers. 'Demon child,' that's what people call us who are born with Devil Fruit powers."
I gave a bitter smile. Calling the human heroes of that time "demon child" felt strange on the tongue. "With the power of one of those five people, a wall was built to separate the human zone from the demon zone. Humanity was able to rebuild the civilization destroyed by the demon attack. After that, the world was governed by six families and one clan."
I rose from the bath, dried off, and dressed casually. I made myself a cup of tea and sat on the sofa. Placing the cup of tea on the table, I closed my eyes and murmured, "TRAINING PANEL."
I saw a square panel in my mind, something only visible when I closed my eyes. This panel contained data on the abilities I had trained all this time—a simple system that I brought with me when I was reincarnated into this world.

Seeing the results of my hard work so far made me smile. "Even though this system seems plain, it gives me a clear view of my training progress. It's an incredible advantage. Others have to train blindly, groping in the dark to measure their progress. With this system, I can stay one step ahead."
