I kept reading how this is “different” or “emotional” from other power fantasy isekais. It’s not. I was actually excited because the author actually had the guts to kill off some main characters, only to undue it, introduce the generic ‘mysterious administrator/message box’ trope, revive the killed of characters, and give the mc a skill that lets them revive anyone, only to never mention it again. Death should be permanent! If anyone can come back to life all willy nilly then there are no stakes, there isn’t any drama. This is just another isekai with no story.
Side note: The group translating this, is awful. They keep changing one of the MAIN characters names over and over again, even after chapter 100. And the grammar is just downright sloppy. You will be filling in for a majority of dialogue.
