So...standard revenge story in a Tower of God knockoff setting? Ehh.
It's nice seeing that Tower of God's creative setting has inspired copycats, I guess, but revenge stories that spend all their time drooling over how evil heartless "badass" the main character is are lame. They're "the perfect, beautiful, kind heroine gets superpowers and everything they want" stories, aimed at people who idolize cynicism/assholery instead of kindness and want to be rewarded for it.
