A series that quite clearly seems to be trying to ride the isekai wave after sword art online made waves with it's debut, this one attempts to market itself as new and unique and different, but in reality is rather bland, and it's attempts to do so are rather pathetic.
The series describes the main character as being transported to a new world with his video game avatar and NPC's but the only relevance of video games here seems to be to justify the main characters asspulls as "video game logic", or "because it follows video game rules" etc.
The main character being evil seem to be the gimmick this isekai decided to run with but apparently it is simply the gimmick, and not an integral part of the story. The initial volumes see the MC doing little to no evil, instead it almost feels as though the author is testing the water on how much evil (or in this case jerk behavior) the audience can stomach before they drop the series entirely, but he spends so much time doing it, that by the time we actually get around to the MC doing "evil" stuff, it literally contradicts prior written character behavior and the "evil" seems to come from the most contrived and senseless scenarios.
It is true that this series seems to follow the "villains" as the main character, but make no mistake, this is not the kind of villain that is understandable or interesting or charismatic enough to hold the weight of a franchise or move a story forward. This is the kind of disposable, bland villain you find in B movies. Look past the gimmick and the aesthetics and you see a series that is particularly bland and has little to no substance.
