well, the fact that it's not really important is the reason for putting it there....... some people think that in durarara openings the people shown on the credits are completely random, so they try to make fun of it. though, basicaly, those people are the ones who tell the story in each episode!
Well done I must say, this has made me want to watch Steins: Gate all the more. I have only seen clips (majorly of Okabe speaking english) but it gives me a Durarara!! feel.
Epic!!! and what spoilers guys? If someone didn't watch Steins;Gate he wouldn't know anything from that :D too complicated anime :D Do u speak japaness? lol
