Lady Ninja Kasumi 4: Birth of a Ninja (真田くノ一忍法伝　かすみ　誕生！猿飛佐助) 16 years old

Once again, Lady Ninja Kasumi is a candidate for a dangerous mission that will use all of her abilities as both a kunoichi and a woman. Her clan elder approaches a specific former member of their group, Sakichi, for his aid in the matter. Unfortunately, due to a tragedy and a lost love, he is unwilling to lend his help to the Sanada ninja, and Kasumi volunteers to handle the matter. Ultimately, she is captured and it is up to Sakichi to help her get to safety... but not before she settles the score with a rival lady ninja.
