It's strange this has all the no effort isekai trademarks in use, yet this isn't isekai. What's the point? Isekai has a totally overpowered MC right from the beginning because it's escapism literature. They are meant for the Japanese students or black company employees dying under stress in the constant rat race. So, the reader wants the person transported from Japan into the new world to have everything served on a silver platter, with no real effort needed. In this series, however, the MC is an original denizen of that world. He's not a stand-in for the poor Japanese person sent to a paradise. So, why the extremely poor writing that only exist to serve the isekai escapism? Maybe the author just didn't realise that.
