I think holy knight hero is really tired to be a saint everywhere he go, so he try to escape this by going dark edgy knight 8th syndrome and go away from his country ; but he's hopeless with anything other than light magic (where he's OP as fuck) and has the godess from this world having personnal attention to him since he's her personnally chosen holy knight.
Well, it's predictable from the first chapter it will be comedy/adventures (and not isekai !!)
It's so shounenish with no depth it actually hurts to read, dropped
Would've not dropped if at least the sad excuse for comedy that's it's trying to pull off would at least be...well comedic. Now it's just overused over the top cringe garbo.
