One Piece – Thundergod Marine - Chapter 1 Sky Island

— Climax exorcism.

An obscene ability that forces forces anyone stricken by it to climax, regardless of whether they are living or dead.

As a bonus, it also forces evil spirits and monsters to ascend to heaven.

This is a world where evil spirits and monsters are everywhere and being an exorcist is a real job.

Talented boys and girls with bright futures are trained at the “School for Exorcists”.

Furuya Haruhisa is a boy cursed with the ability, climax exorcism, and is also the school dunce.

Using the ability could lead to his own social death…

But then, Haruhisa met her.

Misaki Soya, a girl possessing a similarly cursed pair of eyes — demon eyes.

And so begins the legend of how history’s worst exorcists came to be known as the strongest before anyone realized it. Their first official job results in a grand performance with a monster woman who runs away from boobs.

— Nhoooooo!?

A coquettish voice echoes throughout the neighborhood tonight.

It is undoubtedly evidence of an ascension.

Are those useless exorcists using their obscene abilities?

Is ero going to save the world?

A slightly ecchi exorcism performance!!

Vampire Slave Number 43, or the self-named, Azriel Ruinous, learned about the history between the humans and the Vampires and it filled him with rage and hatred.

Nonetheless, he was helpless to do anything.

After years and years of suppression, the Vampires have become the weakest race in the world.

However, lady luck seemed to be on his side as Azriel found an ancient jar filled with mysterious blood that will not only change his, but his race's destiny as well.

This, will be the story about the rise of the self-named, Azriel Ruinous, and the Return of the Forgotten Blood Empire.

...

“Have you heard about the rumour?”

“What rumour?”

“They say that there's a Vampire on the loose, he's out there killing humans mercilessly”

“Hahahaha! That's the funniest joke I ever heard! Vampires? Those Slaves? Hahaha!”

“Yeah, I feel the same! I think someone just started this rumour as a joke! Hahaha! How can those weaklings kill us, humans?”

“True True…”

In a bar, two middle-aged men talked and laughed as they discussed the recent rumour they heard.

Seeing those two, a drunk old man shook his head as he sighed.

“Ignorance is bliss indeed…”

“These younglings do not know what the real fear is…

The vampires may have fallen… but my old bones still remember the days when they were in their prime…”

The old man sobered up in an instant and his body shuddered in fear as the memories of the long-forgotten horror appeared in his mind.

He then took a deep breath as he patted his trembling body and muttered.

“I just hope that they are not back…”

Three years after entering the palace, Yongning Palace’s Yan Shu meiren, has still never met the Emperor.

The palace full of concubines tried to win his favour, only she, immersed in a melon eating system, has no time to spare for him.

How would she know that one day, she actually ate a shockingly big melon——

Yan Shu, “!!! No wonder he never enters the harem!”

Wait…

There seems to be something wrong somewhere… then what did she enter the palace for?!!

The new Emperor, Yu Wen Lan, has two secrets.

Since his ascension to the throne, he has gradually lost his male functions; yet at the same time, he can read minds.

Getting used to seeing their false words and hypocritical faces every day, he grew all the more unfeeling.

That was, until one day, he heard a special heart’s voice——

Yu Wen Lan paused, narrowing his eyes to look in the direction of a delicately pretty and pure looking girl.

Until she ascended to the position of Empress, Yan Shu also didn’t know how she had jumped unreasonably on the Emperor’s bottom line repeatedly, yet had jumped straight in, becoming the first person to be in his heart.

Perhaps, it was just her good luck.
