A born sadist, Nikaido is Keima's homeroom and Japanese teacher. She has been ignoring Keima ever since he told her that there are 5012 games that are more fun than her lessons. Nikaido is also a school senior of Jun Nagase. In the later chapter, she was revealed to be one of the partner of demon called 'Akari'. This might have been foreshadowed from the start of the series, as she always had collar around her neck like Keima. Although she is a human and apparently borrowing all her abilities of capturing from Akari, she is shown to be extremely powerful. She was able to capture level 4 spirit without a single difficulty even though it was not able to be handled by entire run-away spirit squad from the district.
