In the ending montage, they showed Mashiro shaking hands with Midori, which I suppose was supposed to fulfill that promise the two of them made. It seemed implied that she was doing what she said she was going to. If it hadn't already been started, she was definitely going to get to it immediately after the last shot.
I was pretty happy with the last eps. There was a lot crammed in there. Otome does seem a bit like a parody of a couple other series. It's certainly a brighter series than Hime, even though basically no one died in either. Mimi and Erstin were really the only casualties of this series, but they really didn't seem to hit as hard as the "deaths" in Hime.
I really liked the reappearance of Akane. She and Kazuya were arrested for trying to corrupt Akane, hah. Also, her robe had Nekomimi! It was hilarious when she started arguing to the Pillar and they animated her robe more and more like a catgirl.
Also, is it wrong to be attracted to Miss Maria? She even had a katana that was covered in ichor.
All in all, I was satisfied.
