I didn't think about it at first either, but the more you progress and look at the panels, the more you see a familiarity with what we find in AI; there are panels that repeat, the girls' faces look alike, there are points of view that are anomalies (legs or limbs too short because there are too many characters and it doesn't differentiate between the build of a child and an adult)
But after that doesn't take away your experience if it doesn't bother you, the illustrator spent time on it and redrew everything.
I stopped because there are too many girls and i dont like harem xD

Aside from the fact that it's AI, I don't understand the main character's purpose. We've only had information like, "He's reincarnated. He sees a status window," and that's it. There is no consistency except that he has a harem around him. He wants to climb as high as possible in the mage level ? Okay, but why? It make me feel no connection to the character.
