Sayonara Zetsubou Sensei - Season 0 Episode 3 Sweet Princess / Banned Notes / Prototype Shield

Valentine's Day has arrived and Nozomu is rather popular. Wondering if this is a honey trap, appealing to a man's desires to obtain secret information, he is introduced to an elite group of otakus, whose disinterest in real women allows them to carry top secret information without falling into the honey trap. Nozomu then ponders about the violent nature of unaired battles, before Chiri discovers his unaired training. Later, Nozomu goes to a halloween party only to find his ideals about Halloween are much different from current ideals, and dwells upon things not being like the original.
