I Was a Teenage Ninja(Legend of the Voluptuous Kunoichi: Christian Kunoichi Aome's Story)

The movie is the fourth release in the Ninja Girl OV series. AV star Saki Ninomiya stars as Sora, a 19-year-old ninja who finds herself tasked with assassinating a well-guarded shaman. She may not be an experienced ninja, but what she lacks in killer instinct she more than makes up for in feminine wiles.
