About

Recently, there have been minor anomalies in monster habitats and numbers, but it is not a world-scale crisis; it is merely mentioned occasionally as a long-term background element.
[Guest | Errand Boy] A normal person in charge of luggage, shopping, finding inns, and meals. Not a combatant.

Alright, this is definitely the right way!
Leon walks at the front with total confidence. Lilia looks at the map and sighs.
