Character Profile: Dokuro Mitsukai

Dokuro Mitsukai is an angel from the future. She is also the older sister of Zakuro Mitsukai. She is trying to protect Sakura-chan from building a device that will make girls stop aging at the age of 12.

In Episode 1, as she steps into Sakura-kun's classroom, all the boys in his class fall in love.

So... as she is protecting Sakura-kun, she beats him with her weapon, Tetsubo or Excalibolg, by throwing it to the center of his stomach or throwing it to his head. Though after the beatings she brings him back to life with her weapon followed by a chant: "Pipiru piru piru pipiru pi."

And if she's not beating Sakura she's teasing him by using sexual innuendo.
