Review Detail of KolegaKrzysiacy in Blood Warlock: Succubus Partner in the Apocalypse

I did not see anyone mention this in the rewiews, but isn't the story almost a 1 to 1 copy of Everyone Else is a Returnee by Toika? I mean, the succubus comes to the MC the same way angels did in EER. The whole higher existence thing and them being useless is the same. In some rewiew I read that he went to another word to kill some 3 and 4 Order being which also sounds familiar. Even the MC is a blacksmith which was taken out of thin air with a little backstory about it and it was probably done because author didn't know how to give the MC and his subordinates new and better weapons, so he did what he does the best and stole from EER. And to add more it's only the beginning of the book, so later there may be even more things like that. I don't know if the reason there is no comments about this is because mister author deletes them, but i am really suprised that a shameless copy like this is so popular.
