Bokusatsu Tenshi Dokuro-chan

A junior high student in the future creates a method of immortality that halts aging for women once they reach twelve years old, angering a divine entity. In response, an angel is dispatched from the future to eliminate the student. The angel, however, believes the student may be forgiven and decides to keep him occupied to prevent him from completing his invention. Occasionally, the angel becomes violent and strikes the student with her weapon, a bat named Excalibolg, but she can quickly restore his life each time. The angel frequently exclaims, "Pi-piru-piru-piru-pi-piru-pi!"
