The main issue this novel has is that everyone is simply too kind, righteous, or at least honourable for us to believe even remotely. All 4 noble houses are good or decent, the royal family is honourable, the isekai-ed fellows are all good if quirky, the villains are severly overwhelmed and useless,etc. In the end, never mind that it has no suspense, it is simply too idealistic and naive.
Art is good, trans is good after first chap, plot becomes scattered by the 3rd volume(?), ehh 6 or 7/10
