Aske was completely fed up.
Medea's alter ego was definitely crazy.
Indeed, being tainted by Purgatory Will as a new attribute could bring Medea an enormous boost in abilities.
Normally at Lv.3 (Flame I + Mind I + Desire I), the unsealing would elevate her to Lv.7 (Flame V + Mind I + Desire I), and with the ability to absorb pain for enhancement, she could achieve up to a 300% increase in lethality (estimated based on her description).
However, it required torturing enemies and causing them significant pain to achieve this.
Therefore, the crazy lady proposed to Aske voluntarily to allow her, using Medea's body, to join the battles when the team encountered enemies in the future.
Just like how Alexander the zombie did back then, mercilessly torturing enemies with high-temperature flames.
Of course, she would incidentally absorb a bit of the pain, as her reward for assisting.
Considering the team's morale and stability, Aske naturally rejected this request.
