Scorpion Clan Ambassador in Otosan Uchi.
When Tomoe met Yojiro, the ambassador was at least distracted, and possibly senile, but that may also be a ruse.
Yoto's Who's Who
Yojiro has dedicated his life to service, first as an emerald magistrate and trusted advisor to both Emerald Champion Doji Satsume and Emerald Champion Kakita Akio, and now as the representative of the Scorpion at the Imperial Court. Known throughout his life as “the honest Scorpion,” Yojiro is held in high regard even by those hostile to his clan.
