History WMG / SayonaraZetsubouSensei

* This is given away by his occasional CatchPhrase, "I could have died!" He uses it whenever someone's attempt to stop his suicide ends up endangering his life in some other way.

* [[Videogame/EarthBound Giygas]]. The Pororokka aliens abducted two humans from Japan, who studied their secrets and then escaped, taking Kafuka with them. However, the true depths of the alien powers were so terrifying that Kafuka's father went mad and tried to kill himself. As she grew up, secret agents of the invasion force frequently chased them and tried to take Kafuka back, but her mother lied and told her they were things like debt collectors; she has a fake name for her own protection, although she isn't aware of it. Her mother's exorcism was really her being tortured or driven mad by the aliens. In the future, Kafuka will discover her origins, go mad with evil power, and possibly destroy the world/reality as we know it.

[[WMG: Mayo is related to(possibly the sister of) Ryuji from LightNovel/{{Toradora}}]]

[[WMG:Kafuka is another LightNovel/HaruhiSuzumiya-person.]]

There will be at least one ''Anime/PuellaMagiMadokaMagica'' [[ShoutOut reference]] / [[ProductPlacement plug]] [[OnceAnEpisode per episode]], just like ''[[LightNovel/HaruhiSuzumiya Haruhi]]'' in ''Manga/LuckyStar'' (especially with Kafuka and Kyoko [[Creator/AiNonaka sharing a VA]]).

[[WMG:Itoshiki is the author of the book of [[Literature/TheBible Ecclesiastes]]]]

[[WMG:Sayonara Zetsubou Sensei is the personification of Wiki/TVTropes {{expy}} in the form of an anime.]]
While it is true that SZS focuses only on social and cultural tropes that apply to UsefulNotes/{{Japan}}, you notice that in every episode, Itoshiki-sensei introduces a trope in a form of a rant and then his students chip in and bring up examples including [[PlayingWithATrope subversions, inversions, deconstructions and other ways of playing with a trope]], all in an entertaining form, just like Wiki/TVTropes.

* Actually, he ''might'' [[http://www.onemanga.com/Sayonara_Zetsubou_Sensei/86/12/ have slept with a man once.]] But since it looks like the guy is just starting to coax Itoshiki's clothes off, we don't know if he went through with it. However, when you consider the situation as a whole, this might just be evidence against the above theory. He had some [[PoliticalCorrectnessGoneMad weird motives]] for sleeping with/almost sleeping with the guy. And there's [[OhCrap the face he's making]]. Funny when a guy ''accepting the advances of another man'' seems to be the only indication of his possibly being heterosexual. [[GagSeries Only this show...]]

** Well, Kafuka ''is'' a GenkiGirl and she wears [[HairDecorations hair decs]] like Haruhi.

* So, in other words, he's a male equivalent of [[Franchise/DanganRonpa Junko Enoshima]] ? [[OhCrap Oh shit.]] This can't end well.

* Or, they are all a bunch of supers in a certain [[VisualNovel/{{Danganronpa}} high school]]. With Itoshiki as the unluckster. (or maybe a previous graduate....)

The series has made some direct references to ''{{Peanuts}}'', and this makes a surprisingly large amount of sense:
