Most isekai have a main character ridiculously overpowered in a fantasy world. Their problem is how you keep progressing a main character so buffed up already and finding any challenges? It could be like dragon ball, a race to power with stronger opponent at every turn, which also can get old fast. I like DM because, for me at least, shift the focus out of the main character; i get more view on the girls and their evolution as they stick around a mature godly figure who is helping them. Thanks again for the chapter Eraser-kun.
