From the anime Bokusatsu Tenshi Dokuro-chan, Dokuro Mitsukai is an assassin from the future brought back through time to kill Sakura Kusakabe. Instead though she decides to save him. She has a magical staff that is called the "Excalibolg" which she uses from time to time to beat her victims to death with. Mostly she brings these people back to life by chanting "Pipiru piru piru pipiru pi".
Why I like her: Excalibolg is an awesome name for a weapon! She is super duper energetic in everything she does. I loved the scenes where Sakura would end up seeing her naked. Funny stuff.
Why I hate her: I think just *sometimes* she takes things just a *little* too far.
Overall: A bloody good time!
