If you guys know anything you will know jinwoo is lowball outerversal in ragnarok and would outclass saitama by alot and even if saitama becomes stronger than the opponent he fights sung jinwoo can speedblitz him and touch him before he even gets stronfer and take him to his dimension where he is omnipotent and anyone else in there loses all their abilities so they are just normal humans in his dimension and also jinwoo has immortality so its a win for jinwoo mid-diff
