I nominate Doubt&Trust for one of the best OPs ever. I'll start watching once they go into the Arc though. Cause I bet we get some fillers before that.
Became one of my favorite Japanese songs of all time too. I don't like the scene where all the major exorsits just spin around, though. They repeat the same ones after a while, and them all under the Uber-Akuma doesn't make sense.
And I'm glad that they didn't go and spoil Allen's sword in it, because it looked like they would when the Earl and Allen clashed, and we don't need anything more than what's shown. They foreshadowed to the Piano anyway.
