Ishizu Ishtar is a character in the Yu-Gi-Oh! manga and the Yu-Gi-Oh! second series anime. Her name is sometimes rendered by fans as Isis Ishtar (as "Ishizu" is a possible pronunciation of the name "Isis" in Japanese). Her name supposedly derives from the Egyptian deity Isis and the Mesopotamian deity Ishtar.
Ishizu's straight black hair trails just below her shoulders and features 2 locks wrapped in gold beads coming from behind her ears and continue in front, stopping at her neck. She is slender in build and has tanned skin. She wears the Millennium Necklace around her neck prior to giving it to Yugi.
Ishizu's first outfit consists of a long ankle length dress partially bearing her shoulders featuring gold patterns around the neck and the rims of the sleeves. Her jewellery consists of a gold piece of headwear circling her head and featuring an emerald where it meets at the front.
During the Battle City tournament she wears a cream colored sleeveless one-piece dress with the bottom similar to a sarong, a matching waist length veil which widens and spreads below her shoulders and gold sandals. Her jewellery consists of gold braclets, ankle braclets, armbands and brooch bearing the Eye of Wdjat on her veil. She initally wears a piece of cloth over her mouth to conceal her identity.
