The content of the mission that Yasmin took was to simply hunt 20 Inferno Wolves and 10 Man-Eating Eagles in the mountain range near the Islefield Fortress.
She has to collect their fangs and beaks as proof and the rest of the beasts' body parts can be dealt with however she wants.
Aside from that, she needs to coordinate with the Hunter Association's branch there to ensure that she wouldn't just purchase the proof and that she'll really hunt them.
This is quite an important mission considering how they need to lessen the number of strong beasts around the Northern Region.
"Can we help you kill these beasts?" Aria asked curiously.
They are now in the carriage traveling to the fortress and were discussing Yasmin's mission. Lyrei was still their driver at this point since she could easily control the horses and monitor their condition.
Anyway, Aria doesn't know anything about how the Hunter Association operates.
