Rebirth of the Demon King

1|First sight

"Don't go! DONT LEAVE ME HERE" Muzan Kibutsuji, the creator of all demons, spoke his last words as he lost control over the boy he had hoped would succeed him, become invincible, everything he dreamed to be.

He struggled to fight, to survive, to avoid death, to be undefeatable but It was of no use. He couldn't do anything.   In the end, Sunlight killed him. A demon he made helped the demon slayers to weaken him, so that he couldn't avoid sunlight. His upper ranks were dead. Tanjiro broke out of his control. It made him sick, not being able to control a mere weakling whose swordsman skills were nothing, as compared to Yoriichi-the only person who had been able to hurt him.

For a long period of time, he was in complete darkness. Unable to think, unable to feel.

Then one day.............

 He-the demon lord- was born again;without memories of his past life. Even so, he loathed sunlight. Why, he didn't know.

Years passed, he was 20.

He went out to get some fresh air that night.

If he knew what was going to happen, he would've just stayed home.

-

A curvaceous and slim girl  with dark brown eyes, long eyelashes and very pale skin arrived on spot, right in front of him. Her  black hair flowing with light pink ombre, She was wearing a dark blue dress that covered her completely. The moment Muzan saw her face, he was speechless. He felt weird. His heart was beating at an abnormal rate, and he felt like looking at her beautiful face for eternity.

"Hello sir" She said, and he snapped back to reality.

"Who are you" Muzan asked, quite coldly.

"My name is Sayuri Akuma, what's your name?" The girl said.

"Muzan Kibutsuji"

"Well hello Muzan, I need your help. None of my friends are free right now, and I need to get some revenge; And you seem just perfect for it. Will you help me?"

-

"That was sick" Sayuri laughed as they ran  from the grumpy old man who had scolded Sayuri. They had just broken 2 of his windows, without showing their faces. She knew she had just met Muzan for the first time a few minutes ago, still she felt comfortable with him.

She abruptly stopped, Muzan stopped too to see why she had turned beetroot.

Then, he saw him. 

Something triggered in him on seeing that boy, like hate-at-first-sight.

"Giichi!!" Sayuri exclaimed

"Hey  Sayu" Giichi's gaze shifted to Muzan"Who is this?"

"Oh, that's my new friend, Muzan Kibutsuji. Muzan, this is my 'friend', Giichi Tomioka"

"Hello, Tomioka"

"Just call me Giichi, Kibutsuji" 

-

Sayuri was walking to her university with Kiyoshi, Giichi and Izumi. she had met them on her first day and become a part of their group. 

On their way, they met Hayami. Sayuri's only competition in beauty and her biggest enemy.Hayami was a tall, curvaceous, and slender girl with lime green eyes, long eyelashes and very pale skin.

They glared at each other and were distracted when Sumihiko Kamado and Tojuro Rengoku jumped across the closed gate, as usual, late.

Both were really good friends of Giichi, Izumi and Kiyoshi, but since Sayuri was new, she was just civil with them.
