school student, living a peaceful life with his old friend,
Narika. One day, he falls in love with a girl, Haruka. A while
later, Takamaru and Narika are suddenly attacked by strangers.
And Haruka in a kunoichi (female ninja) costume appears and
saves them. Haruka respects him as her master and urges him to
have sex with her. Actually, Takamaru is a boss of his ninja
troop and has a special ability that he can give a huge battle
power through sex. Haruka gets the power from Takamaru and tries
to defeat her enemy. But it is just the beginning of a
long-lasting war....
