People in Demon Slayer: The Journey That Began with Demon Slayer

It wasn't until she was seven years old that she was able to eat some liquid food to maintain her nutrition. At this time, she was still full of hope. Although she no longer hoped to fight against Muzan, she still wanted to live well and take care of her loving parents in their old age.

By the age of fifteen, Yosuke's mindset had completely changed. He had no hope, only despair. He just wanted to be free from his illness as soon as possible. However, his parents were unaware of his thoughts and were still trying their best to prolong his life.

Until now...

As the revolving lantern light ended, Yosuke laboriously opened his eyes, looked at his anxious mother in front of him, and sighed inwardly.

What exactly did I experience during these 16 years of time travel?

Yosuke's thoughts gradually drifted into slumber. He knew that perhaps when he opened his eyes this time, he would never open them again. He vaguely saw his father come into his room, his hand clutching a doctor's, pleading:

"Doctor, please, save my child..."

After an unknown amount of time, Yosuke woke up. The first thing he saw when he opened his eyes was his parents looking at him with concern.

When Takuto Ubuyashiki and Mikako saw Yosuke awaken, they joyfully embraced him, weeping uncontrollably.

"Am I...not dead yet?"

Yosuke was stunned. Had he just made a sound? Was it true?

Ubuyashiki Takuto and Mikako were also pleasantly surprised.

Mikako asked incredulously, "Yo...Yosuke, you just spoke, didn't you?"

"Mother..."

This wasn't a dream; Yosuke really made a sound. Mikako hugged Yosuke tightly, afraid that it was all just a dream.

“Gentlemen, Yangjie has just woken up and needs plenty of rest. Let him sleep for a while. I also need to go check on Wuyi; he also took the medicine I developed and should be waking up soon.”

A man dressed as a doctor offered advice to Yosuke's parents.

Ubuyashiki Takuto and Mikako now listen to this doctor completely because of his miraculous healing skills. He developed a special medicine that allowed their youngest son to recover and wake up. Now, only their eldest son is left to recover.

Yosuke was the only one left in the room, staring blankly ahead.

"Ding, the system has been successfully activated. The host has been transformed from a human into a ghost."

"Ding! A random initial skill has been granted to the host. Activate?"

Yang Jie's face turned bright red, he was so excited he couldn't contain himself.

"I knew it! As a noble transmigrator, how could I not have some kind of cheat code? Hehehe..."

Yang Jie rubbed his hands together to confirm that it was turned on.

"Ding, congratulations host, you have obtained the Blood Demon Art: Shadow Wolf."

Host: Yosuke Ubuyashiki.

Constitution: A demon of nascent origin.

Abilities: Super-fast self-healing, blood transfusion, Blood Demon Art: Shadow Wolf.

Yosuke couldn't wait to use his Blood Demon Art.

"Blood Demon Art? Shadow Wolf!"

Yosuke discovers that his shadow has transformed into a three-dimensional wolf-shaped monster, which he can command to attack at will.

Yosuke, who had just gained his powers, was having a great time until the sun rose and shone on him, at which point he stopped.

"Oh no! I forgot I'm afraid of sunlight now!"

The sunlight shone on Yosuke's buttocks, and the instant it hit him, Yosuke felt an intense burning sensation, and the skin on it rapidly ulcerated.

Fortunately, Yosuke hid quickly, and in the shadows where the sun couldn't reach, the wound on his buttocks healed completely in the blink of an eye.

Chapter 3: Scum of the Human World, the Birth of Muzan (Kibu Yoshimura)

The sun was already high in the sky, and Yosuke could only hide in a dark corner to avoid the sunlight.

"Murder! Murder!" Suddenly, shouts came from outside.

Avoiding the sunlight inside, Yosuke called out towards the door, "Is anyone there? Someone come here!"

The maid who had been taking care of Yosuke opened the door and came inside.

Yosuke asked, "What happened outside?"

The maid replied, "Maiden...Maiden killed the physician!"

The maid's words were like a bucket of cold water poured over Yang Jie's head. Because of the butler's summons, the maid closed the door and left the room.

Yosuke froze on the spot, his eyes glazed over: "Holy crap, so fast? I was planning to familiarize myself with my abilities and then sneak into Boss Zha's room to make a move, but now Boss Zha has become a ghost too. How am I supposed to kill him? Drag him out into the sun for a sunbath and then die together?"

Having just acquired the system, Yosuke didn't want to die a heroic death so soon, so he could only plan ahead.

Yosuke: "System, are you there? Are you there? It's urgent!"

System: "Just say what you need to say, don't ask if I'm online."

...This system of mine has quite a temper.

Yosuke asked cautiously, "Besides being given initial skills, what other ways are there to improve strength?"

System: "Yes, the fastest way is to eat people."

Yosuke: "...I won't eat it, get another one!"

System: "Slaying evil spirits or training can also improve your strength. When the system detects that the host's strength meets the standard, it will give you a chance to win a prize."

Yosuke had a slight headache. The only ghosts in the world right now, besides himself, were his vengeful older brother, Ubuyashiki Mai, but he just couldn't seem to do anything about him...

Forget it, I'll just exercise...

Yosuke stayed home obediently, practicing his katana and training his body.

"Kendo proficiency +1, +1..."

...

Although Mai Ubuyashiki committed murder, as the child of the head of the Ubuyashiki family, the matter was suppressed, but the entire Ubuyashiki family seemed to be shrouded in a shadow.

As time went by, rumors began to circulate within the Ubuyashiki family.

"The two children of the head of the Ubuyashiki family hide in a dark room all day long. What's even more terrifying is that there are rumors that the eldest son, Ubuyashiki Mai, is secretly eating human flesh and blood!"

Everyone in the Ubuyashiki family was filled with fear and unease. No servants were willing to serve Ubuyashiki Mai, because within seven days, anyone who had been in contact with Ubuyashiki Mai had disappeared.

At first, Takuto and Mikako, who were happy that their child had recovered, had gloomy expressions on their faces.

Because of Mai Ubuyashiki's actions, Takuto Ubuyashiki was also removed from his position as head of the family and became depressed all day long.

Mikako was deeply distressed and fell ill, unable to get out of bed.

As night fell, Yosuke left his room and went to his mother's room.

Seeing his mother's haggard face, Yosuke felt a pang of heartache. His beloved mother was now in such a state.

Yosuke buried his head in Mikako's arms and whispered, "Mother..."

Mikako opened her eyes, saw her child, and gently stroked Yosuke's cheek: "Yosuke, you're here..."

Mikako stared in astonishment at Yosuke before her, his face contorted in pain, his skin pale, and his fangs sharp.

Mikako felt a pang of sorrow: "I should have realized it. You two brothers also took that drug. Yosuke, tell your mother, did you... eat people too?"

Yang Jie hurriedly shook his head and said, "No, Mother, although my body has undergone some changes, I do not crave human flesh."

Mikako gently ruffled Yosuke's hair with a sigh of relief: "That's good...that's good. Yosuke, your brother has completely changed. Don't become like him. He...he can no longer be called a human being..."

The Ubuyashiki family's villa has now become a restricted area, and no one dares to set foot inside.

The remaining members of the Ubuyashiki family wanted to eliminate Mai Ubuyashiki, but none of them survived.

Yosuke didn't dare go to that place either. Although he had become a demon, it seemed that apart from having a stronger self-healing ability, he had no other use. Going there would only be a death sentence for him.

Yosuke left Mikako's room and returned to his own.

As Yosuke stepped into his room, cold sweat dripped incessantly from his forehead.

In front of Yosuke, Ubuyashiki Muzan was sitting in a chair, gnawing on a human hand as if it were a chicken claw, which sent chills down one's spine.

"So, you've become a demon too..." Mai Ubuyashiki's cold voice reached Yosuke's ears.

Yosuke's body stiffened, and he dared not make any movement. In the blink of an eye, the human hand in Ubuyashiki Mai's mouth turned into a pile of white bones, without a trace of flesh attached to it.

Yang Jie couldn't help but think to himself, "I can't even gnaw chicken feet as cleanly as you!"

Get started first!

"Blood Demon Art? Shadow Wolf!"

Yosuke's shadow transformed into a shadow wolf, roaring as it charged toward Ubuyashiki Mai.

Yosuke's hopeful gaze turned to disappointment the next second.

From behind, Mai Ubuyashiki extended a long, barbed whip, which broke Yosuke's Blood Demon Art with a single strike.

A gust of cold wind blew by, and Ubuyashiki Mai instantly appeared beside Yosuke. She looked at Yosuke with disdain, grabbed Yosuke's arm with one hand, twisted and pulled, and ripped Yosuke's arm off.

Yosuke roared in pain. Although his arm regenerated instantly, the pain did not disappear. The intense pain caused Yosuke to fall to the ground.

"How weak, Yosuke. You've never eaten a human before, have you? Even as a demon, do you still have any pity for humans? How laughable. To us, humans are nothing but food..."

Mai Ubuyashiki lifted Yosuke's arm, took a bite, and then spat it out.

"This is really disgusting. I thought that since you are also a demon, you would taste better, but I didn't expect you to taste so bad. As my younger brother, you are not even worth being devoured by me, Yosuke."

Yosuke was already prepared; he knew that Mai Ubuyashiki, who could eat people, was definitely stronger than him, but he didn't expect her to be so much stronger.

Mai Ubuyashiki donned a top hat, stepped out of Yosuke's room, and surveyed the Ubuyashiki household, seemingly making a declaration:

"From this day forward, I am no longer Ubuyashiki Mai, but Kibuyashiki Muzan!"

Ubuyashiki Mai Y, no, now it should be Kibuy Muzan, disappeared into the night.

Kibuy Muzan completely left the Ubuyashiki family, and no one knows where he went.

Meanwhile, in the surrounding towns, there were frequent reports of ghosts and monsters eating people, and everyone immediately associated these events with the Ubuyashiki family.

Suddenly, the entire Ubuyashiki family was subjected to public condemnation. Unable to bear the pressure, Ubuyashiki Takuto chose to commit suicide as an apology. Upon learning the news, Mikako's condition worsened once again.

But that wasn't enough, because Yosuke was still alive, and everyone banded together, wanting to pull Yosuke out to bask in the sun.
