This opening.
AAAAAAHHHHGUUU
Which opening is this?
Also, remember when Conan characters had faces instead of muzzles? I like this style a lot.
This isn’t an opening. It’s the closing sequence used during the entire Clash of Red and Black arc: http://www.detectiveconanworld.com/wiki/Yukidoke_no_Ano_Kawa_no_Nagare_no_Y%C5%8D_ni
Oh, that thing I still haven’t watched and skimmed through in the manga… Right. :D;;;
