Top result for "bushou moe" (in Japanese).
But the Bushou Moe-girls got their big break this year when a bushido moe character was created to be the mascot for the Tenchijin Suishin Project, which appears to be some kind of historical society devoted to the Muromachi period (1336 to 1573).
I'm not entirely clear on the details, but it's kind of an interesting concept-- I have this mental image of a bunch of cute little girls trying to attack big burly samurai men, and they win only because the samurai men just can't bring themselves to harm the moe girls.
