Soshi Mutsumi was the wife of the Soshi Daimyo Soshi Taoshi. She gave birth to triplets, which was considered a bad omen among the Scorpion Clan. Her three daughters were Soshi Uidori, Soshi Yukimi and Soshi Miroko. Because of the bad omen, Miroko existance was hidden from everyone. Taoshi used his magic to wipe all memories of the youngest triplet from the memory of those present at the birth, including his own wife. She died alongside her husband in the War of Spirits, slain by Hantei XVI's troops.
