Mika Takei is not an average assassin; her skill for murder is only surpassed by her skill with more sensual arts. But when she fails to fulfill her latest mission, it costs her dearly. Set in the not too distant future in the city of Naru, a criminal organization known as the MOB fights to gain total control of the city. The only thing standing in the MOB's way is the careful 'manipulations' of the assassins. For the sake of the city's future, Mika must rekindle her own passion before returning the favor to those who set her up.
