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

This marriage alliance with the Elizabeth family would only end up benefiting the Luther family in the long run.

Therefore, she accepted the situation with a heavy heart and decided not to foil the wedding completely. She put all the weird and destructive thoughts that kept popping up in her head aside and focused on her family's progress instead which allowed her to distract herself.

On the contrary, Luna who had been the first to know about this development was completely unaffected. Even though she should have been the most affected by the situation because she had been Zach's first woman, Luna supported Zach unconditionally. Just that little bit of reassurance from Zach earlier had been enough for her to set all her worries aside.
