- Description from Novelupdates

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.

«You're a Duchess. No one will dare to consider your words a lie: if you say that you were painting souls, then it's the truth.»

I’ll avoid major spoilers, but a few things will be revealed.You might find this concerning at first, but just check the book cover—it shows the main character and his only partner. She first appears at 10 years old, but rest assured, there’s no inappropriate content or early romance.At around 13, SHE starts developing feelings for the protagonist, but he doesn’t respond until she’s an adult. With her determined personality, she tries to seduce him at 17/18, but it doesn’t work. Their relationship only happens much later.The book has nods to other works, with my own spin on them, and focuses on avoiding elements I find problematic in other stories.Lastly, the beautiful book cover was commissioned and created by HDIArt.
