Hanzo, after realizing how much Sen has changed, wonders if she is still needed. When an invisible enemy attacks, their bond is put to the test, and Hanzo decides she must protect the princess at all costs.
With suspicions that his sister is harboring Yukimura, Sen's older brother sends in a spy to discover the truth. Meanwhile, at the dojo, a new enemy appears, and she seems to have a long time grudge on Yukimura.
The power is up for grabs! Yukimura theorizes that Muneakira will turn whomever he kisses into a Master Samurai, and thus the game begins. While she bones up on technique, Sen and Hanzo lie in wait, ready to stop her no matter what.
While Sen figures out what to do about the "girl who fell from the sky", Muneakira and the others wonder what to do about her. Jubei, however, seems to have different plans (though she may not know it), and they all start with a kiss.
