Except as far as we know TakiYuki doesn't have an aquarium fixation :P

And from what I know of those two, I would actually see it more the other way around -- or is that what you meant? 'Cause Setomaru seems rather reserved when he's around a lot of people. TakiYuki, on the other hand, I think is carrying on the grand tradition of Oishi's actors being total dorks. ♥
