Lady Ofuku. Or as I'd like to call her, "Lady Oh-F#(%-You!" She killed a woman while she was pregnant, poured salt on the open wounds of the Kouga/Iga feud, and worst of all... SHE GOT AWAY WITH IT ALL SCOTT FREE! If I could at just one edit to the story.... I'd have Gennosuke's eye power similar to Lelouch Lamperouge's and have Ofuku's soldiers kill her instead of themselves.

I also hate Kagurou. She attempted to kill Oboro for her own selfish reasons even though Oboro wanted to be merciful with her, It made me just want to say to Oboro, "I know you want to respect her for being a human being, but no matter how much kindness you bring her, she still wants you dead. I know you don't want me to kill her, but it's for your own good." At least she did die.
