Weird coincidence, I just finished watching the episode. I didn't expect the show to turn bloody after a sappy romance between the the Katana guy and the kendo girl. Sometimes, I feel they should just go show and not tell especially light novel series gets too wordy and unnecessarily complicatedly.
The red guy at the end remind me of Suzaku from Code Geass. He's like the Suzaku to Gary Stu's Lelouch for some odd reason my brain made up.
Thank god, this arc is over. It was too long for me to enjoy compared to Black Bullet's short arcs. For Black Bullet, I would have prefer to keep the first arc longer and bring in recurring characters earlier. They did that for the 2nd arc in Black Bullet.
