Well, we'll see how it looks when it's fleshed out. :)

I'd like to think that perhaps instead of being erased, it would be...repressed? Like the mark would still be there, but it wouldn't activate or something. In this Yuu's case, the powers inside him seem to be more deeply connected than canon!verse, and I doubt they'd be erased that easily. Also, it's stated that the Crimson Dragon did choose the power of bonds, and if this Yuu still holds his bonds close, which may be probable-he's only seeking revenge for repetenance, not hatred like the rest of the DS's revenge is still revenge however, gleeeee-there's a chance that the power is still inside him, and if whomever the Savior duelist is who duels him manages to link with him, to trigger those powers, it could reverse his DS-ification. So, he might not be a complete DS. :o?
