the choice to give secco randomly purple eyes in the anime is kind of sick given the outfit basically focuses solely on them. the colored manga gives him light blue eyes instead which don't really stand out very much in the lighter art style
i don't really like the grateful dead's anime coloration... i think it's really VIVID in the colored manga because the orange and yellow stand out versus the dark purple, whereas green/yellow on pale blue is a bit meeeeeh, you know?
something i find kind of interesting that the seiyuu doesn't do in the anime is the way he goes
"And you're super strong... or so.... I thought" (totemo tsuyoi... tte....... omotteita.....)
isn't quiiite as stretched out, so he only pauses after tsuyoi
in eng they have this guy say that he won copies of exodia from players all over the world instead, but in jp the ghouls specifically actually are counterfeiters lol
