Ok, I bet there's someone out there a lot smarter than me who can tell us what that binary on Ran's tabard means...
absolutely nothing, it's just a bunch of random 0s and 1s for the sake of a joke. And even if it did mean anything, it's improperly formatted so there's no way of telling what that message might be.
Going by the Seiga tags, apparently post #2166502 is "Ran Manga 1"
