Nah, miss me with that "perfect" shit....Let the kirito fans or warever enjoy their perfect OP isekai protagonists.
Characters need quirks, consistency, weaknesses and strenghts, we wouldnt like Luffy and Zoro soo much if they where not idiots, or Sanji if he wasnt a pervert cook, or nami if she wasnt greedy, Ussop if he wasnt a weak liar that always manages to surprise everyone with his luck, etc....
