Remember the tale of the little mermaid that fell in love with the dashing human prince? Now, imagine the roles reversed, as a romance blooms between the beautiful Evyione and a dashing young merman. It's a unique twist on a timeless tale that is sure to leave you spellbound.

Kasia Del Roman is a soldier crafted to become an assassin. She lost her human emotions long ago and lived her life as a simple tool, just to be thrown away in her final moments.

Around 50 years ago, after the Korean War, Demon World Gates appeared abruptly all over the world.
Through the Gates, Demon creatures appeared. These otherworldly beings, utterly impervious to modern weaponry, rained destruction across the world.
Just when all hope for humanity was lost, the "Masters" awakened: humanity's one chance for salvation.
With the appearance of these entities, the world began to change rapidly.

Fast forward to 50 years later-
We meet Gang Kyu Sung, who had worked for a small company as a deputy who could never catch a lucky break nor even got promoted.
That is, until he happens to awaken as a Master...?

A Rank 5 Master who had once been ignored and scorned-
Thus begins the uprising of a man who works his way up from the bottom!

I spent years preparing for the civil service exam.
But I can’t believe I died so unfairly…!

Is that so?
I was reborn as a beautiful countess.
I even got the ability to play games from the God of Beauty.
‘Drawing..?’
Yes, I have the ability to draw for characters.

I have become the apostle of the God of Beauty and benefited the world widely by drawing out ultra rare characters.

[Rare-!]
[Super Duper Ultra Special Rare-!!!]

Let's fill the world with handsome men to benefit all the women!

“Renya Kunugi, you have passed away!”
So said the young girl who styled herself God.
Apparently, Renya Kunugi the Protagonist had lived long and prospered. His life already came to a peaceful and fulfilling end, but at the request of Her Holiness, he was transported to an alternate world to start a new life as a young man.
Thus did Renya, who was definitely your average everyday guy, end up fighting off bandits and vanquishing monsters. Eventually, after his successively blossoming talents coalesce into a force of sheer awesomeness, he will go on to leave his mark upon this alternate world.

A pervert with great martial arts skills, a klutz of a nun, a dojo master with a bombastic imagination, a volatile code of chivalry, a mentally unstable patient who flippantly gives out internal energy… and so many experts who’re castrated? Hehe—So this is murim?!
