Author having caught up to the current chapters hope you don't plan on making Nux stronger than Azriel at any point.
That would be bad writing. Their experience, age and growth can't be compared in any way.
Question Author???If Amelia is a year younger than Asher and she is Rank 6 and a D rank in her current year doesn't that mean if she had entered the Academy at the right time or a year later she would be a genius like Asher in terms of ranking up speed???
