Ninja That Stand Atop Skyscrapers - S1.E1

Asuka, Ikaruga, Katsuragi, Yagyu and Hibari are five school girls who secretly train in the ninja arts. As they are sent by their mentor, Kiriya, to handle some delinquents in town, Asuka meets a girl named Homura and helps guide her through town, unaware that she is secretly an enemy shinobi. Meanwhile, the others encounter the delinquents, who are soon revealed to be wooden puppets controlled by an enemy shinobi. As the girls manage to beat the puppets, Asuka remains blissfully unaware of Homura's true alliance.
