Oniwabandana was a Youma created by Kunzite from Nana Asahina, a photographer for a sleazy tabloid. She took the form of a ninja who used shadow clones, throwing knives, a sword, and her bandana as weapons. She was notable for adding the word "banban" at the end of many of her sentences.
- Oniwabandana's name is likely a compound of the words "oniwabanshu" and "bandana." Her name in the English dub, "Ninjana," was similar to the word ninja.
- Oniwabandana also made an appearance in the video game Sailor Moon S: Quiz Taiketsu! Sailor Power Ketsushuu.
