The Reze arc is memorable because Makima "kills" Reze in the end, in other words, its a tragedy. Without the tragedy it would be just another piece of shonen slop fantasy with a sexy girl with superpowers for 15yo kids to masturbate. But in this way Reze becomes a "curse"
This if Fujimotos formula. What I want to say is that AsaDen is fucked as well. Asa is fucking dead.
