And now, the story falls in pieces. I started reading the novel because I thaught it would be a nice "average" isekai, the MC has a strong power, but nothing overwhelming. It has is everyday adventure, being a servant of a noble family. But now, I directly warn you: it's one of the most cliched isekai. He has become overly OP (he gained pretty much all powers), has "evil" powers but is good. A game system appears out of nowhere. Magical beast becoming waifus. You name it, it has it.
