No, Naruto did not marry into the Hyuuga family.<br/><br/>Why?<br/><br/>Because I say so.<br/><br/>... And because my secret vice is GaaHina. >.< Given, between his position as Kazekage and hers as heir of the Hyuuga (who would never let another village get the secrets of the Byakugan), even if anything were to exist between them, neither could leave his or her village for the other's, but the inevitable tragedy of the pair is part of their draw for me.<br/><br/>*ahem*<br/><br/>So, no, Naruto didn't, for purposes of this game, marry into any major clan (as I, at the moment, don't really care whether Sakura ends up with Sasuke or Naruto, I'll leave it ambiguous).
