If not compared to an exception like Lette, Emily's progression can only be described as insane.
There might be contributions from Lette and Lilith, or perhaps the support of powerful Power of Soul provided by the Witch's plan.
But Emily's own determination and unwavering heart are also unparalleled.
One of the reasons that supports this determination is her hatred and resentment for the Tower of Truth.
Lette's desire to dismantle the Tower of Truth is due to ideology mismatches and disgust for their actions.
But for Emily and the other witches, it's the victim's profound hatred for the perpetrator.
The saying "one cannot live under the same sky as the enemy who killed one's parents" is the same in any world.
And the harm and torment brought on by the witch's curse bring endless regret and sorrow for generations upon generations.
Therefore, when the opponent revealed their identity, the flames of hatred instantly devoured Emily completely.
"Ah!!!"
