Rin Sai (柴 凛)
Rin Sai is Sho's twin sister, and renowned as the "manliest woman in Sa province." When first encountered, she is the head of the Merchant Guild in Koren. After her term of guild leadership expires, she becomes an inventor. When Shūrei calls doctors to treat the disease in Sa province, Rin designs a smooth knife suited to surgical operations; Rin later designs a centrifuge-like device to separate out sand from adulterated salt. She fell in love with Yūshun Tei when he was still Ensei's assistant and repeatedly proposed to Yūshun on the Autumn Festival (an event similar to Valentine's Day, when girls give handmade gifts to someone they like). For years, Yūshun had always rejected her. When the Sa conflict ends, Rin announces her last attempt to propose to Yūshun: if he rejected her again, she would give up and wish for his happiness when he returned to Shi province. When Rin approaches Yūshun, he seems to be asleep, so Rin just gives her gift, wishes for his happiness. However, when she turns to leave, Yūshun suddenly grabs her wrist. They are described as newlyweds when they go to Shi province for the New Year's celebrations. (Source: Wikipedia)
