Yuri, Marth's your ancestor

This is pretty much a Tales of Vesperia/ Fire Emblem crossover.

For those who are confused, Marth Lowell is a Super Smash Brothers character and the protagonist of the first Fire Emblem game.

His surname is revealed in the Fire Emblem anime, which only has like two episodes.

So of course I thought of Yuri. And what he'd think if Marth is to be his ancestor. That'd mean that he's of royal descent.

Most likely he'd dismiss it with a wave since he's a cynic and a realist, and Estelle will be all enthralled by the tale.
