Maou na Ore to Fushihime no Yubiwa - Volume 3 Prologue

In the near future of South Korea, where everything is determined by aptitude tests, the protagonist Kang Moon-soo gets the job of a “Shaman”.“A shaman? What’s that? Do you earn a lot of money? Is it stable?”The profession of shaman has nothing in common with Moon-soo’s aspirations. He ends up becoming a freelance problem solver, a million light-years away from a stable life!Will Kang Moon-soo be able to sustain a livelihood as a shaman?

In this period where countless supporting lead actors always attempt to counterattack, turn over a new leaf or simply refuse to take up the role, his purpose of existing is to fill the role of a good supporting male lead and uphold his duty to the best of his ability. To add the needed lustre to storylines and this world. Only, it’s a pity that someone who is not afraid of god-like enemies will be afraid of pig-like teammates.

Bitterly, he realises that for some unfathomable reason, he is being bothered time and again by a bastard who refuses to follow the script… In order to walk the path of a good supporting male lead, he engages in a battle of wits and courage with that person. Loving each other and killing each other, one ultimately cannot escape fate’s teasing– why is it so difficult wanting to be a responsible and diligent supporting male lead?! QAQ

Su Yun came to a comprehensive world that was about to collapse due to a mysterious recovery, but he didn’t panic at all.

Because, he can edit the stories of the two-dimensional girls and broadcast them publicly, and gain enough prestige by publicly executing the girls, and then he can…

So…

“Artoria, I am your previous life, King Arthur!” Su Yun, who was in the form of a dumb haired king, looked at Artoria, a foreign student with a bewildered face, and said valiantly.

“The evil spirit, that’s me, that’s you! Tokisaki Kusan!” Su Yun, who was transformed into the elf of time, stood in front of the stunned Tokisaki Kusan, with a seductive smile on his face.

“Balzebu, the power of thunder is my power, and my shape is also the power you should have. Now, try to take out the power that belongs to you from your body! It’s called – Dream One Heart!” After listening to General Thunder’s words, Balzeb subconsciously stretched his right hand to his chest.

Morgan Le Fay, Tamamo Mae, Miyamoto Musashi, Yae Kamiko…

One after another, mortal girls who had no power before, all showed their extraordinary side to the world under Su Yun’s bad taste.

So, people really think that they do have extraordinary power, and therefore, they have really gained extraordinary power.

The world has been completely changed because of this, and the mysterious history that human beings cannot overcome is rewritten!

This was an era where everyone could experience various worlds through simulations.

When everyone reached 16 years old, they would receive a Life Lantern, which would grant them two free simulations.

During the free simulations, they had to break through the limits of humans in order to attain a bright future in reality.

Otherwise, they would lose their Life Lanterns and they would slowly be corrupted by a black fog until they eventually died at a young age.

Lin Qiye, who transmigrated to this era, failed his first simulation.

During his second simulation, by chance, he acquired a permanent SSS-rank talent – the Deduction of Genesis.

Lin Qiye’s first life: [When you were two, you had a sudden illness, causing you to have a deformed head and low IQ. When you were 15, your parents passed away. When you were 18, you died of an incurable disease.]

Lin Qiye commanded, “The Deduction of Genesis, deduce for me a way to transcend this life.”

[Congratulations for defying the heavens and successfully changing your fate. You acquired S rank in your evaluation. Your rewards are…]

…

His second life: [When you were 15, the spiritual aura on Earth rejuvenated. You did not awaken any talent while your childhood best friend achieved outstanding attainments with her awakened talent. When you were 16, you were killed by a stranger.]

Lin Qiye summoned, “The Deduction of Genesis!”

[You carefully made plans before the spiritual aura rejuvenated. Because of this, you defied the heavens and successfully changed your fate. You acquired S rank in your evaluation. Your rewards are…]
