I watched one episode of Medaka Box and was suuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuper confused (especially by that character). Then I realized I had apparently started with the follow-up anime/second season/whatever. On a tangent, I REALLY hate it when anime do that. Like Magi. It's not Magi: Labyrinth of Magic season 1 and season 2, no, it's Magi: Labyrinth of Magic and season 2 is Magi: Kingdom of Magic. Which means that in most lists, the second season SHOWS UP FIRST.
