Her main objective was to spy on the Sailor Senshi and gather more information. Oniwabandana robbed OSA-P to lure the Sailor Senshi out. Sailor Moon and the rest of the Sailor Senshi arrived to stop her but ended up having an argument. While they were distracted, Oniwabandana reverted to her human form and snapped photos of them, attempting to question them. After suspecting that Nana (Oniwabandana) was indeed associated with the Dark Kingdom, Sailor Moon agreed to meet her and claimed to give her more information about leaving the Sailor Senshi.
