When asked about the topic of the Saikyou no Yousei, she will typically respond with "all of us have limitless potential, so why can't it be me?" There is a softer side to Nineball she rarely shows, which reveals her to be a silly, carefree person with a penchant for practical jokes - particularly those involving ice or other cold objects. She is known to have an affinity for ice cream and other frozen treats. Despite her history with the Youkai Nation, she isn't more prone to attacking activists than she is to attacking anyone else, and her reputation is enough to stop all but the most bold and/or stupid activists from trying to bring her in for desertion.
A few mercenaries jokingly call her 'SevenballThreeball' on occasion, in reference to the red camouflage she wears and has painted on her weapons. Nineball doesn't seem to mind as long as it's not too frequent. She claims to have never played pool, with her callsign not being a reference to the game.
