Indeed, my favorite part of this episode was when Togame decided not to complain about Shichika killing the woman. Protecting the enemies was never part of the promise Shichika made to Togame when he decided to be her sword. If he had to do even that, no doubt he would have died in the 2nd episode when he fought against the Namakura sword.
Still, I am not sure how Shichika actually feels after having killed that woman. It is only his 4th kill, including his father, and it was someone who he at least had built a certain connection with. He looked extremely lonely and miserable when he was just standing there with his hand all bloody. His behavior returned to normal when he faced Togame though. Is this because he is too ignorant of his own feelings due to his upbringing to respond to his emotions properly? Or did he intentionally hide his emotions to protect Togame by preventing her from feeling guilty over dragging him into the whole mess?
I really like the hair scenes in this show. While I did not like the slapstick parts of this episode, the other sections definitely made up for it.
