While I'll agree with Laclongquan and Sederva that ohkimch's review seems to be spawned from over the top outrage, there are indeed too many lolis in this manga. Looking at the source material, a Web novel and Light novel's information and reviews, more lolis are to be expected. At least, the artwork for the Light Novel has the Luna character appearing a bit order on the cover than she does in the manga. However, in the reviews there are talks of time skips, so there's that.
If you like lolis, and I personally can't justify them or shotas, anyways, if you like lolis you'll like this I guess.
As far as the story goes, it's your basic "another world" set up with some changes. Instead of the MC being the usual average person or high level gamer transferred to a fantasy world or game-like world, the MC is a game creator transferred to another world in the body of one of his characters with the nickname Demon Lord with the ability to use his game creations so long as he has enough skill points to purchase them with a creation skill. He also has his character's game skills. While the MC's Demon Lord character seemed to be the villain of the game he created, he is not the Demon Lord.
One of the trope it suffers from when it comes to isekais is the plot forced or MC's desire to stay under the rader while not staying under the radar. In this story, whenever the MC decides he wants to hide his usual face, he switches to a character he seems to not be able to control for some reason. Like most isekais this is done when the MC suddenly wants to be icognito at some particular point in the story despite having just performed an action that would make him well known.
The other problem with this is when an older woman is introduced, she falls for his alternate persona rather than the usual persona of the MC. Oh, the WN and LN both have harem in their genre tags as well, so it's obvious the lolis are included in that along with an assistant the MC summons that he created in his original game world. So far she is an Evil Science Genius who for some odd reason MC made into a shotacon, but it's played up for laughs so far since only one shotacon boy has shown up and she hasn't met him. Still, she has shown emotion in response to MC's praises and has internally monologued how that feeling was new. So it's possible she would be one of the few older females attracted to him.
Still, so far whenever he switches to his alternate character, who has his own personality again, it's always done in front of the people who think MC is evil. Thus, they see his alternate persona as a hero and still see MC as a villain. It makes no sense. MC rationalizes this as somehow reducing his exposure so he wont have to answer questions (again that isekai trope of being icognito while not being incognito) but given MC wants to clear up the misunderstanding that he's not a Demon Lord, you'd think he'd swoop in and do the deed without switching character personas? Again, when he does it, it's in front of many of the adult women who then favor his alternate persona rather than him.
Then when he speaks with them, especially the rational saint female, he comes off as the Demon Lord like he's playing a part rather than simply say his intention is not to do evil, instead to investigate the angels and simply do things that benefit himself and those around him? Yet, his intention up to this point was to clear up the misconception that he was the new Demon Lord of their world.
Another issue with this story is it lacks direction like many isekais. So far there are only 11ish chapters at the time I write this review and the MC has started a plan to start a business while investigating who brought him to this world. He knows the small fry who did it, but is looking for a stronger power, a deity who backed the small fry. However, the small fry, called Satanist, for some odd reason in this manga, have been constantly getting in the way with their rivalry against the supposedly good religious group in the story that worships three mysteriou angelic beings.
Is the story horrible? No. Well depends on your feelings about lolis, I can't justify them as I said, but their insertion so far is tolerable. It's not like another isekai manga where the lolis were throwing themselves at the MC sexually. So far there seems to be one-sided romantic feelings coming from the lolis whereas the MC sees them as a father would a daughter, well at least one loli. The other he antagonizes because of her attitude.
I gave this a four because I wanted to see where it was going and I didn't hate reading it up to the most recently translated chapters. I've seen worse isekai so I can't justify giving it worse and I can't justify giving it higher. One cold probably argue for a five making it average at best.
