Of course, such a flaw could hardly be considered a weakness in battle.
After all, even Retsu Unohana had spent several days before finally confirming that there was something wrong with the corpse Aizen Sosuke had left behind.
In a Soul Reaper's battle, victory and defeat were sometimes decided in a single instant.
However, Ailin was not among those who could not sense Aizen Sosuke's spiritual pressure.
