[Myssa Rei]

There's also an alluded span of time that was skipped between the acceptance of the sisters into the household, and that scene.

Spoiler for Comparison to the Kotowaru manga:

If I remember right, a whole season's been skipped (winter to spring), and the reason that the Hero is actually hunting wild animals was to build trust with the villagers (since the meat of the wild animals he hunted would be used by the villagers as they worked), as well as increasing safety in the area around the village in the process.
