Frieren didnt bother hearing them, because demons only use words to deceive.
Then it dawns on him:she wasnt fighting fair.
His last words are Youre a disgrace to all mages.

Fern already knows that, as does her master.
Its why she beat him, and its why Frieren will beat Aura.
Flamme decides to take Frieren in and make her her apprentice.

Her first lesson to her is to never directly engage the enemy, especially when it comes to demons.
Flamme then reveals hertruemana, not the one she let the demons see.
Its so large it takes up the entire frame.

Essentially, by being cowardly and unfair and mocking magic itself.
After all, her mana is several times wider than Frierens.
She knows this because Flamme told her demons dont conceal their mana, nor can they.

It is their pride and their dignity, their identity.
To see a demons mana is to see their whole, unguarded selvesas well as their limits.
She asks Frieren to do so around her grave when she passes, and Frieren does so.

And he would be right.
Not until she already has her and Frierens souls on her scales.
She believes shes won, because she can see Frierens mana isnt that impressive.

But as she gets closer, the scales start to tip more in Freirens favor.
Aura can no longer scoff and claim to be the stronger of them.
Nor can she control herself any longer, as the scalesshedeployed have turned against her.
Taketatsu Ayana effortlessly switches Auras voice from haughty confidence to pure fear and panic.
Just as demons deceive with their words, Frieren, like her master, deceives with her mana.
Lugner and Aura can call it unfair all they like…because life aint frikkin fair.
