Louisa is an elven adventurer affiliated with the Alpine party in Tsige, holding the specialized Job class of "Bless Gunner" focused on archery combat. She wields a bow in battle, augmenting her offensive capabilities by enchanting her arrows with Wind magic. While acknowledging her marksmanship falls short compared to Makoto Misumi's, training from Tomoe significantly sharpened her skills, enabling her to confront and defeat powerful monsters with relative ease. Her personality is bluntly straightforward; she often expresses herself without filtering her thoughts or choosing tactful words, leading to occasionally harsh or socially awkward interactions. Louisa forged close bonds with fellow Alpine party members Hazal, a human alchemist, and Ranina, a dwarf Priest Knight. As the party's core, they frequently collaborate on missions. This professional partnership deepened into personal commitment: Louisa, along with Toa and Ranina, entered a polyandrous marriage with Hazal, as documented in Web Novel Chapter 375, solidifying their familial unit. She first appears narratively during Makoto Misumi's arrival and adventurer re-registration in Tsige, identified as an elven archer. Her subsequent involvement centers on activities within Tsige and her development through the Alpine party's adventures.
