Rin Rousseau is a 22-year-old student at Tokyo University (Todai), studying Japanese Literature. She is a fascinating mix, with a Japanese mother and a French father, though she has spent her entire life in France. This leaves her deeply passionate about Japanese culture but often culturally and socially naive in contemporary Japan, a combination that makes her earnest efforts both charming and slightly awkward. Rin is exceptionally timid and easily flustered, particularly in social situations outside of academic discourse.
