Bokusatsu Tenshi Dokuro-chan II

Summary: 

    Bokusatsu Tenshi Dokuro-chan tells the story of Sakura Kusakabe, a second-year junior high school student who sometime in the future is going to offend God by inadvertently inventing immortality. Women are affected so that they stop aging after the age of twelve and Sakura is accused of creating a "Pedophile's World". Dokuro Mitsukai, a member of an order of angel assassins that are called Rurutie, has been sent from the future to kill him. Believing that Sakura can be redeemed, Dokuro decides instead to keep Sakura so occupied that he can never develop the immortality technology. Due to her impulsive nature, however, she frequently kills him with her gigantic spiked kanabō (club) she has named Excalibolg on a moment's impulse, but returning him to life moments later with angelic magic. Sabato, another assassin of the Rurutie order who uses her feminine wiles to do her jobs, is dispatched to complete Dokuro's original mission: Sakura's assassination.
