Rin is an apprentice carpenter who is popular on Airan due to her somewhat tomboyish outfit and attitude she was the subject of a lot of attention and romantic interest from other women before Ikutos arrival. She found this situation so uncomfortable that she developed a tendency to bathe alone. Rins busty frame belies her amazing strength although she thinks of herself as feminine: unlike the other girls she hates being seen naked and likes to dress in pretty clothes when no one is watching. She is also an excellent chef in fact as indicated in the manga she is far better at cooking than she is at carpentry. Initially Rin propositions Ikuto to be her husband to prove her heterosexuality and so end the advances made on her by the other girls however she soon develops real feelings for him. She calls Ikuto danna hubby or husband much to Ikutos chagrin.
