To experience love, the Japanese man Yuuto drank a love potion but was deceived and lost his life. He reincarnated as a Dungeon Master but was not enthusiastic about his role, which inherently involved forcing others to fight. However, Yuuto noticed something.
“Wait? Aren’t these monsters kinda cute when you look closely?”
From then on, he abandons his duty of making monsters fight and, instead, finds purpose in life by raising 13 monsters to be as strong and beautiful as his students.
Ten years later, the monsters somehow transform into beautiful girls and are eager to repay Yuuto for his kindness. However, they’ve become highly obsessive Yandere fanatics due to the doting they’ve received from him for the past decade!
Furthermore, all 13 have become extremely rare and unique monsters, the strongest of their kind. Unbeknownst to Yuuto, their desire to repay him becomes a world-scale endeavor.
“Ah, I kind of want to go to the beach.”
“As you wish, Master. It’s difficult here… (I need to conquer the most beautiful beach on the continent right away).”
“Oh, that sounds good! (I have to bring the nearby monsters under my control too).” “Understood! I must prepare swimsuits (Ah! I must dedicate all the nearby beautiful women for my lord’s beach outing).”
Oblivious to his influence, our protagonist, Dungeon Master Yuuto, unknowingly begins to conquer the world through his monster subordinates! Is this okay, protagonist? The story is getting bigger and bigger; you must stop it soon!

The author attempts to create intriguing characters, but their efforts are undermined by excessive melodrama, which quickly turns everything into a mess. To avoid spoilers, I recommend reading the first chapter to grasp my point, but my advice is to look elsewhere for a more engaging read; this one simply doesn't cut it.
The story started focusing on monster girls, which temporarily distracted me from my annoyance. I viewed the protagonist as a symbol, hoping for the narrative to revolve around their conquest of the monster girl world, as hinted by the title. The introduction of the cruel and pragmatic goddess was a refreshing change, breaking away from the usual portrayal of gods as subservient.
Unfortunately, the plot took a sudden downturn, only to revert back to the norm in the next chapter, leaving me bewildered. I nearly abandoned the book then, but the world-conquest plot involving the monster girls finally picked up. However, the translation quality started deteriorating, making it difficult to distinguish between dialogue and thoughts. The author's descriptions also became vague.
If the author has indeed altered the story based on reader feedback, it seems to have negatively impacted its potential for greatness, steering it towards mediocrity at best. I genuinely hope for a manga adaptation, as they often provide a clearer and more engaging narrative, like in "I Can't Exploit My Slaves Because of Their High Expectations and Evaluation," where the source material struggles with clarity but the manga version shines.
