Yet another reason to watch Dandadan. The intros can often dictate how the anime in question will be or is, knowing how psychedelic the animation and now this OP is, we are undoubtedly facing one of the biggest surprises of the year. As I've already told several people here I want to see it all in one go, that's why I haven't sat down to watch it yet.
But yes, with every thing they write about it the hype goes up and up.
Cheers!
hahahahaha I think I'm going to do the same as you, I saw the first chapter and I liked it a lot although due to time issues I have not followed, I think the most exciting thing would be to wait for the season to end and watch it often as a Marathon :D
