Story is not that bad though the first 100 or so chapters the mc is an idiot or acts like it. From about chapter 200 up, he acts dumb but it is shown that he is actually manipulating the individuals around him not unlike what can be seen in other novels. Characters are so-so, they have little substance the only interesting ones are his junior sisters and the old masked man. Worldbuilding has been slow it has only so far given information about the continent he woke up in. This is good for casual reading but do not expect much from it. Nyoi-bo Studio is incompetent they change the names and titles of everything constantly making it impossible to keep any semblance of order when reading this story, I would advise not reading this until it is completely fixed. But if you want to tough it out the errors start at about chapter 421.
