Nejishiki has charcoal gray-colored hair and tannish skin. He wears a Japanese kitsune mask, often worn in Noh theater and Matsuri festivals. He also wears a red headscarf and a yellow yukata (light summer kimono) with a green sash.
Nejishiki is seen with Rat watching Arale race the Gatchans. He is seen again playing with some strange looking monster people, including Gamera, while General Blue stops at the Phone Booth where he met Sourman. Nejishiki makes funny faces at General Blue with the monsters.
- Grandpa Gohan wears the same variety of mask as Nejishiki.
