@aFFi:
His stats from chapter 1:
Level 1 - physical power: rank F - magical power: rank F - (no idea what): rank E - (no idea what): rank C - (no idea what): rank C - luck: probably rank B (hidden completely by MC's head - taken from chapter 2 cause "luck" is usually the stat that does not increase with levels).
-> already at the end of chapter 2 reached:
Level 12 - physical power: rank D - magical power: rank D - (no idea what): rank D - (no idea what): rank C - (no idea what): rank C - luck: rank B
So if this goes on he will reach rank A or maybe S by chapter 10 for the first 3 stats.
Hence I think he will not turn out to be one of those MCs that simply get help from stronger locals / inhabitants of that world but become one of the strongest himself.
