How is this an Overlord rip? Lets list the things in common -
1. Video game becomes real other world - which frankly has been done many times before Overlord and we'll see plenty more of.
2. Other world has fantasy like setting - so that's like 1000s of others and not Overlord specifically.
2. MC with a skeleton-like appearance. Which isn't all that significant to the overall story at this point considering he wears full armor. It isn't all that significant to Overlord either.
That's it and it isn't much. In every other way this is nothing like Overlord. I'm betting your view is entirely based off point 3 which is beyond weak.

I'd agree it would be better if they'd take a few cues from Overlord or any manga where the MC has a bit more ambition and was at least a little selfish. A little selfishness doesn't make you a bad person - it makes you normal and believable. The whole "I don't want to be noticed" except for strategic reasons is also silly and unrelatable.
Yeah the villains "evil for the sake of evil" is a bit weak. Although that works better when the villain is actually insane. But then once would question an insane person building up a base of support. Villains that are uncaring about others are believable though.
