Jay was merely an abandoned butcher’s son, living in a small village on the outskirts of a magical world. When humans came of age, they would receive their class from a mana conduit, granting them magic powers, and begin their lives as adventurers.

[Necromancer Level 1]
“...I’m a Necromancer?” His eyes widened in shock. Looking around in fear, he breathed a sigh of relief. No one heard him.
This was a monster class, and one of the more powerful monsters at that; a powerful being which raised the dead to fight on its behalf. If anyone knew, they would hunt Jay down and kill on sight. He was not just a threat to the authority of the nobles, but to all living things.
“But am I a monster now? Or human? I guess it doesn’t matter. They’ll kill me all the same.”
Jay had only one option: to get stronger, building his necrotic powers up so that he may one day become untouchable.

Through plotting, secrecy, and sometimes by sheer carnage, he can only attempt to survive in this hostile world.
Join Jay as he struggles against all odds and misfortune, against a world that wants him dead, as he secretly rises and bends this world to his will.

“Yes, we agreed to that, but not to a sexless marriage. Sex is essential for a lasting marriage.” Selene chuckled.

Clint also smiled, then sneered. “Do you like sex without love? Did you marry me because you enjoyed the sex that much?”

Selene frowned, aware of the implications of his words. But she did not know why he said it.

And the unopened file named “HER” appeared in her mind again.

“I believe it’s important for a healthy relationship.”

“Only the sex?”

“I thought we agreed on it.”

“Nonsense!” Clint exploded with anger.

After thinking for a while, Selene replied, “Okay, sorry for disturbing you. I’m going to bed.”

Before she went back to the bedroom and lay on the bed, Clint suddenly caught up with her and pushed her onto the bed. “What are you doing?!” Selene was frightened.
