If I remember correctly, Solomon had 72 household members, so I seriously doubt that Ugo is the only not-clan-leader and/or Human among them. I'm fairly sure that Paimon and Lelarge used to be Human.

Speaking of Djinns... the one currently testing Sinbad & Co in the spin-off was most likely a Manticore. I wonder if he'll turn out to be the baby Manticor that first almost ate Sheba and then became friends with her.
