1 Chapter 1: Transmigration

"Urgh…ah, my head hurts! Wh-what the-? What happened?"

A black haired boy around the age of 7 woke up. He tried to move from his bed only for him to be greeted with pain all over his body.

The boy leaned back to his bed to relax his body for a while. When the pain subsided, he looked at his surroundings and noticed the unfamiliar place.

"Where am I?" He observed the place and concluded that he's in a hospital. He turned his head to the window beside him and saw many trees outside.

He took a deep breath in. "It's refreshing."

When he was about to get off of the bed, footsteps were heard outside the door.

*Tap tap tap*

The door opened and a nurse came in. She looked at the bed and wasn't expecting to see the patient already awake.

"You're awake." The nurse approached him and assisted him to lean on the bed.

"Don't force yourself to move yet. Wait here and I will call the doctor." She said and hurriedly ran outside to notify the doctor.

'I guess I was asleep for a long time, huh?' He ignored the nurse's words and got up from the bed. He was about to get off the bed when he suddenly fell.

*Thud!*

Fortunately, he was fast enough to react and was able to put his arms in front to protect his head from bumping to the floor.

"What the?" He got up and almost fell again but he was able to balance himself by grabbing the bed with his right arm.

He tried to walk but his balance was so off that he couldn't stand properly. Thinking about what to do, he lowered his hips to have a better feeling on his joints and muscles, spread his arms to both sides and then walked to the other side of the room.

This time, he realizes that his body is shorter than his normal height, and by a lot. He also feels considerably lighter than before. Curious about his current situation, he picked a small mirror above the cabinet beside the bed and moved it in front of his face.

Shock engulfed the boy and fell on his butt. What he saw was someone from an anime he had watched before.

He touched his face and felt a silky smooth skin devoid of any rough surface. He pinched his cheek and felt the pain he was expecting. He did this several times with varying time intervals and his guess was confirmed, he is not dreaming.

He transmigrated into the body of a boy who will become a demigod in the future.

Realizing his situation, he refrained himself from thinking out loud any further. In this way, he can minimize the risk of any unwanted suspicion.

He tried to recall memories that he shouldn't have but found out that he doesn't have any. The only things he knows are the ones shown in the anime.

Right now, the best thing he could think of in this situation is to pretend to have amnesia.

*Tok! tok! tok!* A knock on the door was heard

"Come in." The boy said.

The door opened revealing a tall man in a white lab coat with a red kanji word for "medical" holding a list board.

Then there's another person beside the tall man wearing a red gown, white haori and red hat with a kanji word for fire. He is aslo holding a smoke pipe in his right hand. He has many wrinkles on his face indicating how old he is.

"What are you feeling, Sasuke?" The old man spoke and asked the boy who is now named "Sasuke".

"Ah...I'm fine. It's just that my head hurts a bit." Sasuke replied.

"Do you remember anything about why you're here?" This time, the doctor spoke.

Hearing the doctor, Sasuke recalled what happened.

//flash back//

At the middle of dawn, you can see a 15 year old boy walking on the road. It's his daily routine to walk around their subdivision every dawn before preparing his things for his online class.

He stopped on his track and sat down on the elevation of the sidewalk. "Aw man. There's no interesting novels to read. Well, I guess I will just write my own after I get back home."

While he was walking, he felt a strong tremor on the ground, an earthquake. Calming himself down, he stays in the middle of the road since it's the safest area he could think of at the moment. After some time, the earthquake finally stopped and he was relieved thinking that he was safe. But when he turned around, he was smashed by a truck that went out of control.

-few minutes later-

He regained his consciousness and felt very tired. As he opened his eyes he noticed that he was in a dark room. He looked in front of him and saw a silhouette of a person standing 3 meters away from where he was standing. He can't believe that he is still standing after being smashed by a truck to death.

Before he could do anything, a loud ominous thunder was heard, a lightning sparked in the dark sky outside. The inside of the room was also illuminated by the lightning through the windows, lighting the silhouette in front of the boy.

What greeted him was a demon in a human body. Demonic eyes that reflected its hatred and a bloodied ninjato that reflected the countless lives it took. This is the demon incarnate in front of him.

Not only that, what shook the boy to the core was the sea of blood flowing under his feet and the corpses in between him and the man.

Based on the position of the two dead bodies lying on the floor, a man and a woman, they most likely didn't retaliate. The boy quickly made countless conclusions as to how this happened and finally came up with the assumption that it's probably an assassination.

The boy, shaking from fear, fell on his butt and was soaked with the blood. At this point, he had no idea what to do and the thought of dying a gruesome death engulfed his otherwise calm and logical thinking.

'Run!!' That's the word that popped to his mind. Like a cockroach who was about to die, he wails like a swimmer in the pool of blood and screams like a baby.

With a goal in mind, the boy did everything he could and broke the paper-like-japanese door behind him. With his adrenaline at its peak, he surpassed Usain Bolt's top speed and broke all the paper doors in his path that eventually led him outside.

He ran and ran and ran like a professional robber who was caught opening an already opened door with a bobby pin by a grandma.

Like the unlucky bastard he is, the demon was already standing in front of him. He stumbled forward and fell face first. He tried to stand up and ran back to where he came from but suddenly everything turned red and black. That's the beginning of the hellish nightmare that our boy ever experienced in his life.

//flash back end//

Thinking back, he couldn't contain his stomach and puked on the bed sheet.

"Blargh…cough…cough…blargh…cough"

'That's a very cliche way to die, but I didn't even have time to celebrate the fact that I transmigrated and was immediately tortured almost to death.' Sasuke tried to compose himself and answered the doctor. "I-i don't really remember anything." Sasuke answered honestly.

"I understand. Please, don't force yourself to remember things and just relax for the time being. Meanwhile, I will conduct a few check ups." The doctor said and proceeded with his thing.

//A week later//

The doctor tried to help Sasuke remember things little by little to no avail and concluded that the kid had developed a severe trauma that his brain was forced to erase all of the information with connection to the trauma as a form of defensive mechanism.

"Based on your tests and check ups, you have retrograde amnesia. This type of amnesia is very rare and only occurs to children. I'm sorry to say this, but there is no medical treatment that can help you remember your lost memories even with today's medical knowledge. But other than that, we don't see any other problem with your body so you can get back home after a week when we're done with all your examinations. For now, just rest." The doctor said.

Sasuke squeezed the bedsheet, disappointed about the news and said with a sad tone, "T-thanks. Like you said, it's probably better to not remember those memories."

After hearing what the doctor said, Hiruzen sighed and looked more stressed than before. 'Haaa, I don't know what Itachi did but… haais. There's nothing I can do now, it already happened.'

Hiruzen looked to the ceiling and whispered, filled with guilt, enough for the other two people in the room to hear.

"Forgive me…"

He didn't really apologize to anyone in particular but the doctor knew that he felt responsible for the massacre of the Uchiha Clan the other night even though he didn't know the complete details of what truly happened.

"Hokage-sama, you should rest as well. I know you're tired from all your work." The doctor said with worry.

"Ok, I will be on my way now. I have some more things to do. If you have something you need, you can ask the staff here. I will answer all the questions you have tomorrow, ok? Make sure to have a good rest, good bye." After saying that, the 3rd hokage disappeared in the room and the doctor also left after giving Sasuke some more check ups.

Sasuke went back to bed to relax his body. 'That went smoothly. Now what? Considering that my every move will have a huge impact on the events that will happen after this, I need to make sure that I have an overwhelming strength such that something like that won't bother me. I just have to do things correctly and take advantage of my potential.

… But still. That bastard Itachi almost killed me from extreme fear.'

"Blargh", a vomit threatened to climb his stomach but he held his ground, trying to fight the fear he felt that night.

'I now know what needs to be done, but first I need to rest.' He said, leaned back on the bed and fell asleep.
