Bayushi Tozasu

Bayushi Tozasu was a Scorpion spirit who returned through Oblivion's Gate. Tozasu had been killed by a Unicorn centuries ago, and the vengeful spirit began his attempt to slaughter his killer's descendants. His assault took him to the village where the young Utaku Yu-Pan resided, and although she had not come of age yet and he spared her, he still murdered her mother, brother and three elder sisters. This caused the young Battle Maiden to bear an intense hatred for all spirits. (Samurai p. 71)
