Zach was a sci-fi game enthusiast who unintentionally crossed over to a magical isekai. Fortunately, he had access to the previous game system and could fight the magic-savvy aborigines with high-tech weapons.
“Magic? No, I have the lightsaber. ”
Unlike what he expected, the system presented him with a different way of leveling up. He had to get some kind of special energy from the pretty girls' bodies on this planet so that he could unlock his weapons.
"What the hell happened? Is my sperm capable of upgrading girls? Can my blood cause those girls to burst out instantly?"
This was incredible.
The succubi were a hated race in the magical isekai because they oversucked male sperm and killed men, but not Zach.
Surprisingly, the majority of the special energy that Zach required was distributed in succubi.
He appeared to be having a fantastic journey.

Release That Succubus

Her parents had been sold to the royal family as a commodity at an early age and had passed away while Brittany was still young.

Being born a slave, she never knew freedom and had grown up to be timid and introverted. Thankfully for her, the princess had somehow taken a liking to her and had chosen her to be her personal maid.

That very act changed her life forever as she went through a hell of pain as a result.

But Brittany felt nothing but gratitude towards Carol for giving her a better life. Otherwise, she might have died without even growing up. Life as a slave without her parents, the possibility of surviving such an ordeal was infinitesimally small.

She remembered how she tried to find her savior in every other person she came across in the most difficult time of her life.

Looking at the little girl, Brittany felt that she must have appeared as helpless as the pitiful little girl as well.
