[clief101_]

his name is just sephiroth, he has no actual last name..he doesnt even have a birth certificate..in the game booklet everythin about him is unkown (cept his weapon and height and stuff like that)...no birthplace or date.
however, lucrectia WAS married to hojo, but was forced, she was vincents lover yes, but NOT sephiroths father, hojo is, it states it in the game!!
but if he was to have a last name, it would have to be crescent because a babies name takes after its mothers name unless the couple agree to take on the fathers name, because hojo couldnt care less about an experiment, he wouldnt have cared about a last name, so it would HAVE to be crescent
