Finally finished this series and well worth the wait. This jdrama is about a time travelled female ninja partnered with granny, teacher, thief & cross dressing bar keep to fight the fights the police ignore. Each episode deals with the ugly side of human nature capitalizing on the glorious 7 sins, all the while Sana coming to grip with new existence in the modern world with humans still as ugly as in her original era. If you like jdrama, ninjas, no romance, and solid human interest, this one is for you. You felt good knowing the really evil folks get cans of whoop a%* from a female warrior & grandma. Hope they make Tenchu 2.
