Hmm Sephiroth Hojo or Sephiroth Crescent...
I like Sephiroth Crescent better

But I dont think he has a last name, he was an experiment and this is a definition of his name...

`Sephiroth` may refer to: *Sephiroth (Kabbalah), the ten attributes that God created through which he can manifest

And I read somewhere that SHINRA means GOD.
Basically it means "Shinra created Sephiroth with Jenova cells and Mako which he can manipulate and grow stronger from"

I think thats basically what it means. Correct me if im wrong
Anyway because of that I think he had no last name, I think he was just 'Sephiiroth'
