Seven Sins System

Warning: Mature content, R18, Harem, No NTR, No Rape "I only accept an equivalent trade. A wish for a wish. Body or soul, which one will you give me?" It was the same offer every time a mortal summoned him, the crown prince of the shadow realm and the lord of wrath, Azrael Shadowraven de Nightfall. The demons bowed their heads to him. All creatures, mortals, and even angels feared him. However, everything changed after he was sent for a secret mission in the mortal realm to expand his seven sins power. Hiding his identity among the mortals, the vampires were attracted by his royal blood. The mortals were either jealous or admired his abilities. The angels were curious about him. The demons wanted to kill him and take over his power. Little did he know, he had another hidden power sealed inside of him. Something terrifying that could turn him either into the ruler of the three realms or an evil that could destroy all beings. -------------- *Most of my story has a big harem, I'm not interested in writing a small harem with only two or three girls. The MC doesn't treat his woman as a sex object. Non-consensual relationship also not my thing.

The System and The Devil Contract

Seven Sins System Chapter 4. The System and The Devil Contract

After Carl answered me with a nod, he led me to a black hatchback car not far away from the river.

Previously, I thought I landed out of town or something, but I was wrong. It was a park in a city called Erstonia, the capital of Republic Harmonia.

"Um... Sir great demon, thank you for coming to help me," Carl said timidly as he got into the car and sat behind the wheel. He was a bald 40 years old man with a friendly face. His body was a little thin and his height was shorter than mine. His skin was a bit pale. A light blue t-shirt and jeans covered his body.

"Don't mention it," I said lightly, sitting down by his side. A simple white t-shirt and trousers covered my body. Those were Carl's so the t-shirt was too small and the end of my pants was hanging over my ankles. I also didn't wear shoes since he did not have a spare.

Sadly, I couldn't complain. His car back seats were filled with everyday items like clothes, laptops, and a mattress, indicating he had been living in his car for a while. So I knew he was broke.

"May I explain the deal now?" I could catch his nervousness from his words.

"Wait a second." I raised my hand, asking him to hold back his words since my attention was on my system.

[Name: Carl Dewfire]

[Level 2]

[HP: 45/45]

[MP: 12/12]

That meant I could kill him in one hit. Well, I was a royal demon after all. My level 1 wouldn't be as weak as a human's.

'Skill.'

[*Breastfeeding - Whenever her master plays with her breasts, it will stimulate her to produce succubus nectar from her breasts.]

Even though my skills weren't much left, at least I could change my tentacles into seven sins mode now.

Moreover, I bet sex would be more fun with that power of lust. As for my summoning skill, I only could take out 1/4 of my Demonic beast because of my seal.

"Sir?" Carl's voice dismissed my thoughts.

But instead of answering him, I glanced at the window on my other side. My sight immediately caught a few cops walking in a hurry along with the two women who saw me earlier.

Quickly, I turned to Carl who was looking at me in confusion upon my silence.

"Let's get out of here. You can tell me on the way." I came here as a spy, so I didn't want to make a fuss on my first day. I even had to keep myself low profile to avoid suspicion. I knew the light realm's spy also among the mortals.

"Yes, sir." Then he started his car.
