Oh, travelling through canons, it's so hard to determine these things... I guess in America's case with the whole across canons thing and that Umineko dictates children are more likely to see magic and all it might work to an extent with him? Like more so certain cases where it could be argued to be something other than magic (haha Umineko) or something particularly powerful, but that inbetween area might be lost on him? Does that make sense?
