The question is, will they be unlockable or will they be just roaming characters.
Unknown Duelist didn't become an unlockable character, for example. Despite having voice lines (albeit just a copy of Sera's, but distorted) and win/lose image.
It will be in the future, this is a completely new char. Unknown duelist and Sera are the same. They did it this way because it was based on the manga or something. Every roaming character will eventualy became unlockable. Pro hint for the event: don't waste your time farming in the annyoing roaming event. The unlockable event always have the same drops and it will be easier to farm the cards.
