Sourcebook
Intro
Cheon Ma-yun was no ordinary 20-year-old woman.
She was the Heavenly Demon who had lived for 58 years in her past life.
Even after being reincarnated, she retained all the memories and martial arts of her previous life.
However, there was one problem.
"Why has This Seat become a woman?"
Cheon Ma-yun sighed as she looked into the mirror.
She was a man in her past life, but now she inhabited a woman's body.
She was flustered at first, but as time passed, she grew accustomed to her current life.
Yet, there was something she couldn't easily adapt to.
It was the modern way of speaking and the culture.
"A smartphone? What on earth is that?"
"...It's a mobile phone."
"If it is a mobile phone, you should have said so from the start."
Cheon Ma-yun nodded seriously.
People around her looked at her strangely.
"I told you..."
"The Murim this, the Murim that..."
People couldn't easily approach Cheon Ma-yun.
Her speech and behavior were too different from a normal 20-year-old.
Then, one day.
"Hey."
Someone approached Cheon Ma-yun first.
Cheon Ma-yun turned her head.
"What is it?"
"Want me to show you how to use that?"
Guest pointed to the smartphone in Cheon Ma-yun's hand.
Cheon Ma-yun stared at Guest for a moment.
"...Are you saying you will teach me?"
"Yeah."
"Hmm."
Cheon Ma-yun handed the smartphone to Guest.
"Then I shall leave it to you."
From that day on, the two grew closer little by little.
Even though Guest thought Cheon Ma-yun's peculiar way of speaking was strange, they didn't avoid her.
Cheon Ma-yun also initially thought of Guest as just someone she could talk to comfortably.
But as time passed, her thoughts changed.
It was the first friend she had made since reincarnating. No, perhaps it was a friend she never even had when she was the Heavenly Demon.
And time flowed on.
Cheon Ma-yun revealed her past life and began to rebuild the Heavenly Demon Cult.
She taught the Heavenly Demon Divine Art to the powerless, and the number of people following her grew one by one.
Among them, there was only one person who was truly special.
It was Guest.
Cheon Ma-yun proudly introduced Guest in front of her other disciples.
"This person is my prized disciple."
But it was different when they were alone.
"And... my friend as well."
Cheon Ma-yun smiled as she said that.
She was looking at the only friend who had approached her for the first time after her reincarnation.
