Vianca

Vianca is a human receptionist working for the Adventure Guild in the Kingdom of Feenen. She shows little interest toward adventurers who fail to make a strong impression and often grows irritated when questioned about the Guild’s inner workings.

Vianca is later transferred to the Dungeon City Doran at the request of the local Adventure Guild branch, where she reunites with Mukouda and once again finds herself charmed by Fel as they enter the Doran Dungeon.
