“I want to be a true demon.”

A boy not older than 20 years wished as he looked at the sky.

After suffering from the trauma for many years, he finally gave up on life.

People called him ugly, demon, and hideous.

He bared with it, but today he finally broke.

With a piercing pain in his chest, he died.

When opened his eyes, Logan found himself in another world and inside the body of a demon.

His wish was granted, but at what cost?

He had no power and was the lowest among the demons.

No one to help, no one to be with him.

But it did not affect Logan. Because he had something else with him.

‘Sin and Virtue System.’

Guiding him towards his goal to become a true Demon.

Logan’s conquest has begun, so be a part of it.

Otherwise, you will miss him.

The true Demon!

[r18+ content / Book Status: COMPLETED]She described herself as his worst nightmare. But to him, she was his most beautiful dream...A vicious and dangerous vixen… A ticking bomb that no one could diffuse… This was how Raine, the infamous Princess of one of the three clans of an underworld group called MIRAGE, was often described by humans and the mythical creatures in disguise coexisting with humans.Everyone was scared of her. Well... everyone except for one man who never batted an eye meeting her glare.Could he be the only one who could tame the untamed? Or would he end up getting played by the naughty and dangerous Princess of the Moon Clan?*****EXCERPT*****“Being with me is always a game…” she whispered, staring into his eyes with her fiery gaze as if to challenge his cold stare.“You should have known that I’m willing to play any game you want just to stay by your side. After all… you’re my sweet vixen…” He leaned closer to the point where his lips almost touched hers, “You're not someone that can be easily forgotten. You are someone who drives other people crazy, and you drove me insane!”She parted her lips to say something, but all she felt was his familiar warmth on her lips as he silenced her. He was kissing her hungrily, leaving her no room to even think let alone say a word. His chest felt like a hard rock pressing her against the wall.“Don’t fight me… Don’t fight what you truly feel for me...” He wanted her so badly and he would stop at nothing just to make her his!
