A century before the start of the series, Shihoin Yoruichi was one of the most intimidating and well-respected person in Soul Society. She was the squad captain of the 2nd Division, the leader of the Secret Mobile Corps, and the head of a high ranking noble house. Yoruichi has never been seen weilding a zanpakuto, although a kodachi-like blade was shown in some of the flashbacks.
Stunning cosplay by JouninK! I love the location and the kimono she used for this shot; it looks like a young Yoruichi practicing her sword skills! Thanks again to JouninK for sharing this!
