Samurai: Spirit of the Sword (1999) IMDb
A young man is suddenly left as master of the family dōjō. All except one student leave because they do not trust him, but he is friends with various women who help straighten out a plot to topple the Tokugawa government by means of a magical blade.
Edo-period bishoujo, epic fantasy action. Based on a (probably harem) game. One of the better utterly stereotypical series I’ve seen, and it’s short. Possibly a good way to represent anime by means of its contemporary emblems—cute unrealistic girls, ninjas, sword fights, spectacular magic—if you really want to do that. The original title, Kaitouranma, is a figure of speech said to have been the origin of the title Ranma ½ (1989).
