I like Fern character so much. She is so responsible that she is the mother figure of the group but she is still very young so she can get capricious and childish. The manga does a great job of selling those almost contradictory features.
Also she is too cute when pouting!
Finally some real fucking yuri in this manga. I'll of course continue to ship Frieren with her daughtermother, but it's nice to see something I don't need 6 inch thick yuri goggles for.
Fern keeps a tight leash. Stark gains his first female attention outside the party since the cow-milking lady, and 30 seconds later she's got him packed off to hunt monsters with a guy who was trying to kill her two days ago...
