I see a good isekai as one where the characters have nothing to help them as they realise what has happened. This anime however drops the MC in to a world were people he knows have appeared many years before them, which makes for a weirdly uncomfortable situation where the MC just carries on as they did when playing the game.
We have an OP newly loli female character which could have had many of events / shenanigans, but instead is just traveling under the gise of a student of himself and seeing people be blown away at this student who is taught by another OP character (but is actually the same). Its a new direction which I haven't seen for this style of anime, but I wouldn't recommend anyone do it again.
