"So cursed energy is generated by negative emotions like fear, anger, and hatred? No wonder I felt it react when I got upset about something. But I won't always be angry to use it, right?"
"It requires precise control because it's something violent and strong, but I have no problems using it. In fact, I can use it quite easily. Could it be because of the finger?"
Sitting on the floor of his room, Sukuna stared at his hands, which were enveloped in red flames with black details. This was the cursed energy in his body, which had appeared several months before he turned five. However, after eating that finger, his cursed energy surged significantly, greatly increasing his reserves.
But that wasn't all—he possessed knowledge about this type of energy and how to manipulate it throughout his body to strengthen himself or manifest it and use his cursed technique. He wasn't sure why it came so naturally to him. Maybe it was like muscle memory, but he couldn't confirm that.
Considering how powerful yet volatile this energy was, controlling it to a good degree in just three weeks was no small feat. It had been three weeks since he ate the finger and two weeks since he used his cursed technique for the first time.
At that moment, he felt a comforting sensation from having the technique—a sense of regaining something he had lost and deeply valued, even though he used the technique semi-consciously.
He knew what he wanted to do but didn't know how to do it; yet everything happened naturally. As the days passed, he studied the changes in his body, manipulated the energy through it, and observed various effects while using it.
He also experimented with his cursed techniques. At first, he struggled to use them, but within hours, he managed to do so, albeit lacking power. Moreover, his young body couldn't handle large amounts of force, as it would strain itself.
He concluded that the fingers seemed to strengthen his body, soul, and mind, as well as enhance his techniques—particularly the Cursed Relic technique. At the moment, he could perform Kai (解, "Sever") and Hachi (捌, "Dismantle").
He was aware that his technique had other abilities or functions, but he couldn't yet discover what they were. He determined that consuming more fingers would not only make him stronger but also help him complete his cursed technique and fully unlock the Cursed Relic ability.
Setting aside the Cursed Relic technique, his Ten Shadows cursed technique was complete. He had knowledge of the ten shikigami and their hand seals, but he needed to confront and defeat them in battle to summon them and use their powers.
For now, he only had the Jade Wolves, which he could summon without issue: a white dog and a black dog. The only challenge or concern he faced was the cursed energy required.
The first time he summoned them, he used a significant amount of cursed energy and ended up summoning two enormous dogs, nearly 3 meters tall (118.1 inches). This startled him and scared all the children at kindergarten, as two giant dogs had emerged from a shadow.
He immediately undid the summoning and ran away. Fortunately, nothing serious happened, but unfortunately, the school increased surveillance everywhere, making it harder for him to practice his techniques freely.
Another discovery was that all living beings had cursed energy. However, compared to his, it was like comparing a glass of water to an Olympic-sized pool. The cursed energy of others remained dormant. He initially thought people used cursed energy when using their quirks, but they didn't.
He observed several children and adults (heroes) using their quirks, and there were no signs of cursed energy fluctuations. However, he did notice that some people caused slight fluctuations when they were angry, scared, or sad. Beyond that, no one could use cursed energy.
It seemed he was the only one who could wield it at will, possessing far more than anyone else and likely gaining even more in the future, along with a cursed technique fueled by cursed energy. He could disguise it as a quirk for now.
Letting out a frustrated sigh at not being able to use his techniques more freely, he got up from the floor and walked to the kitchen. He was currently alone in the apartment because Ayame had left for work, saying she needed to take care of something without giving further explanation. She only told him not to cause any trouble.
Reaching the kitchen, he dragged a chair closer to the table, took out cheese, ham, and a bag of bread. He climbed onto the chair, placed everything on the table, and began organizing.
He took two slices of bread and a piece of pre-sliced ham. Taking the cheese out of its packaging, he pointed with his right hand and made a vertical motion, slicing the cheese into several pieces.
He added the cheese to his sandwich and began eating it. Then, he grabbed several more slices of bread, jumped off the chair, put everything away, and went to the living room. He turned on the TV and sat on the floor, but not before making a hand seal resembling a dog. His shadow stretched to his sides, and from it emerged two normal-sized dogs.
He gave several slices of bread to each dog, turned on the TV, and began flipping through channels. As the dogs alternated between watching TV and looking out the window, Sukuna drifted into his thoughts. He continued pondering the various places he saw when he consumed the first finger—each location different, yet seemingly connected to Ryōmen Sukuna.
He knows that his main mission is to gather the fingers and then figure out what to do with his future. Maybe he could become someone famous like a hero or a police officer. That's something he can think about later. For now, he plans to enjoy his childhood and have as much fun as he can before facing his destiny.
"Woof woof woof!" x2
He's pulled out of his thoughts by the dogs' barking. Turning his head, he sees them barking intensely at something outside the window, as if they've spotted something unusual.
"What's going on with you two?"
Getting up from the couch, he approaches the dogs. Both jump down from the window and move closer to him, staring at him with a strong sense of pride.
"What's wrong? Did you find something?"
Both wag their tails vigorously and nod their heads. Sukuna looks at them for a moment, and a thought suddenly crosses his mind. He opens his eyes wide in surprise at the possibility.
"Did you find one of my fingers?"
Both dogs nod again, and Sukuna's mouth drops open in shock. He hadn't known his dogs could locate one of his fingers, let alone from such a great distance. After all, he couldn't sense anything more than a few kilometers away, even if it contained a large amount of cursed energy.
"Is my finger far away?"
"Woof woof."
"10 kilometers?"
"....."
"50 kilometers?"
"....."
"100 kilometers?"
"Woof woof."
Sigh
"It's way too far."
His spirits dropped instantly upon realizing how far his second finger was. However, his mood shifted again when he looked at the two dogs, curiosity lighting up his face.
"How can you two detect it from such a great distance? You're only supposed to sense things within a certain range, but 100 kilometers?"
The dogs remained silent. They turned to look at each other as if communicating in their own language, then turned back to Sukuna. Both tilted their heads to the right, radiating confusion.
Neither Sukuna nor the Jade Wolves had any idea how they had managed to detect the second finger.
