Antihero
Author Super intelligence may seem like a great ability but in writing its terrible You need super intelligence to actually portray it In writing I'll read another 20 chapters before giving a review. I'd advise you to change mcs ability to something easier to write about Typical gamers ability would be better, they tend to come with AI's, a map function, description of people, beings or items previously encountered, etc etc
It is clear his ability isn't super intelligence. There is another person helping in the shadows. Who killed the banka monster thing? Who cured his grandfather? I bet the system is lying to him. I think he has the ability to process information from electronic components, which is why he knows these things. Or maybe he is literally just a pawn being used to mature the system. Maybe blue eyes are his real mutation. I love the story and the mystery. Keep it up!
