Generic isekai slop. Not the usual "Its isekai so of course its bad!" But the genuine bad that just gives you a headache. I could go in depth but wasting that much time on this would be just that, a waste. Don't bother on this one like at all.
To cut right to the chase, I see no potential in this. Zero at all. It's your basic revenge fantasy with the "twist" of using existing isekai mcs as the villains for... idk, "symbolism?" And reading the chapter got me straight faced. It relied too much on shock value and I didn't really care...
