I think Yuuta is from the Kurahashi clan a branch of Tsuchimikado clan which are descendants of Abe no Seimei. And for Sano ofc that's just his alias. In the early chapters it was said that he's really not a yokai but a God so his real name would probably be his God name. My theory is that he's Susanoo or Susanoo no Mikoto or the God of Destruction. Just a guess coz Sano Mikoto right? hehe
