A member of Zepar's Household is Pisti.
Zepar's Metal Vessel is a ring that Sinbad wears. The ring has a small Seal of Solomon on it, like all other metal vessels. The ring rests on his middle finger.
In this form, Sinbad takes the appearance of a small imp with dragon wings, hooves, and three eyes. He is able to perform an incredibly loud scream, via Sound Magic, that is able to "command" others into doing something. When used on Kougyoku, he told her mind to sleep. Sinbad has stated that because it is a tasteless move, it effects everyone in the vicinity to some degree.
- His name "Zepar" is probably taken from the book The Lesser Key of Solomon. In the first section of this book, entitled Ars Goetia, several demons are described, Zepar being the sixteenth. As a matter of fact, the dungeon where Zepar resided were the 16th as well.
