Frieren: Beyond Journey's End Episode 10 English Dubbed Episode Title: A Powerful Mage Episode Description: Mortally wounded, Lügner is left to wonder how Fern is so powerful, until he comes to the realization that she had been suppressing her mana to look weaker than she actually is, which is considered a taboo among demon mages. Fern then finishes off Lügner. In a flashback to a thousand years ago, Flamme comes across a destroyed elf village and finds Frieren the only survivor, having managed to kill the demon general attacking her. Flamme decides to take Frieren on as her apprentice and teaches her how to indefinitely suppress her mana. She also teaches Frieren how to fight demons. Since demons are proud and self confident in their own magic and are incapable of suppressing their own mana, Flamme explains that by suppressing their mana, they can trick demons into feeling a false sense of security where they can be destroyed in a surprise attack. Flamme's last instruction to Frieren is to keep training and suppressing her mana and live in obscurity until she is powerful enough to defeat the Demon King. A thousand years later, Himmel and his party track down Frieren and attempt to recruit her. Seeing that Himmel can instinctively sense her true power, Frieren decides to join them. In the present, Aura uses the Scales of Obedience, but is horrified when Frieren shows the true extent of her mana. Aura is dominated by Frieren, and she is forced to behead herself under Frieren's order.
