Isami's Incredible Shinsen Squad

Synopsis
Isami is a just a girl-next-door who lives with her mother and grandfather and goes about a normal young teen's life. Until, that is, evil rears its ugly head. When the nefarious Black Tengu Faction resurfaces in Japan after some hundred years, Isami makes a timely discovery--she and her friends Soshi and Toshi are in fact direct descendants of the Shinsen Squad, a band of courageous samurai who were dedicated to the forces of good. After stumbling onto the old headquarters of that group, the friends outfit themselves for battle. These young heroes are all that stands between the dastardly Black Tengu Faction and world domination. Are they up to the task?
