Many things, including internet culture and japanese culture. Watch it, it's great, even though there are a lot of references I don't get also.
<3 (no homo)I'm halfway through Bakemonogatari and I'm starting to like Shaft more.
There's anime on C31? That doesn't even make sense.
Anywho I am now watching Zoku Sayonara, Zetsubou-Sensei
Higurashi no Naku Koro ni - 8/26
Would you recommend watching Persona 4? I'm somewhat familiar with the videogame series, and I'm looking for a new anime to watch...
