An isekai with a twist, but ends up just being a poorly written power fantasy. However, if looking for some pretty power fantasy action sequences and can ignore some really bad writing, this anime is pretty solid.
Story - 7
The overall premise is interesting in that it reverses the standard isekai premise in that the fantasy world is becoming a part of Earth. The parts which are fleshed out are pretty good, but the world building is left largely to the side in order to focus on the MC.
Characters - 4
Supporting cast is pretty decent, even if they can be relatively two dimensional. However the MC pretty poorly written with conflicting motivations, outlooks which aren't supported by flashbacks or other character actions, poor decision making which is rewarded just cause, etc. The MC is basically given infinite scaling, is handheld through his "growth", and barely has to put in any effort to gain power.
Animation - 8.5
The animation is incredibly solid, especially for action sections. However they are pretty spaced out, and most of them aren't the most interesting fights. e.g. Whack at large monster repeatedly, one shot smaller stuff.
Sound - 8
High quality production for sound, although largely forgettable sound track.
