9 chapters in, and so far it's generic isekai. A group of people get sent to another world, there's a somewhat antagonistic person among them who betrays the main character, because of this betrayal, the main character gets overpowered (note that he gets 'OP' in the most uncompelling way), then he meets his waifu and then he goes on adventures. Considering that most stories of this kind at the very least start out with an interesting hook before succumbing to the typical and now rather boring harem and gary-stu development, this one lacks even a compelling beginning. Though I am early in this story, andthere may be some subversion later on, at the moment, I don't have many high hopes for it.
