As much I want to post about Kuroshitsuji right now, Usui love comes first.
Why? The answer's simple...Episode 13 revealed Usui's look if he decides to become a delinquent, and what do you know, HE IS STILL GOOD LOOKING :)
This is yet another side story animated, and I can say that they did a good job on this. This story focused more on the Moron Trio's past lives before going to Seika High.
Unfortunately, all's well ends well for everyone except for Yukimura who was forgotten by everyone. Too bad for him :|
