I have walked my life on thin ice, kept my vows pure, never broken my oath! … You ask what happened to them?

Hey, isn’t a paladin’s matter not a violation of vows? Besides, monster girls aren’t human! Herbert transmigrated.

Good news: he became a paladin. Bad news: he took the Oath of Purity and must remain pure his entire life! Great, he was given a magic ring right at the start.

This lifetime for sure! Moreover, he was assigned to a prison to reform the most vicious and terrifying alien prisoners. Chaotic dragons, fallen angels, dark elves, sirens, demons, devils…

Me? Reform them? Is this real?

Weak and helpless, he could not match these monster girls at all, only huddled in the corner trembling with knees hugged. Just as Herbert thought he would spend this life suppressing desire and withering away in prison, a dark god forcibly blessed him with a special charm that would mesmerize all monster girls. After that…

the tone of events went off-kilter. When Herbert stepped into the prison again, he found the monster girls who once despised him now looked at him differently—they were all lusting after his body!? It was at this moment he suddenly realized they might not be as terrifying as they appeared.

They have great potential for reform! This book is also known as The Alien Race Girl Evaluation Guide, Playing Monster Girl Raising in Prison [Comedic] [No Shame] [Light-hearted] Already completed with 5 million words total, never abandoned, guaranteed integrity!
