Sayonara, Zetsubou-sensei/Fridge

Fridge Horror

• Sayonara, Zetsubou-sensei is pretty blatant and tries to cross the line twice, but when Maria (the very young and naive but wonderfully Polyannaish immigrant) sees someone about to molest a child, she believes that he's just being a nice guy to children. Refuge in Audacity, right? And then you realize why everybody wants to protect her.
• With the revelation in the manga that Kafuka was Dead All Along, this puts up the disturbing thought that every time Kafuka appeared, she was actively possessing one of the girls in the class without anybody realizing. This also means that since the viewer can also see Kafuka, by extension you have a piece of Kafuka inside you as well!

Fridge Brilliance

• After the revelation in the manga that Kafuka was Dead All Along, a lot of the nonsensical symbolism in the show (particularly the opening and ending sequences) now suddenly makes sense as Foreshadowing when you realize that a lot of it can be interpreted as metaphors for Kafuka's true nature, as well as her ability to possess her classmates. It also explains how she is seemingly everywhere all the time.
