During battle Fuuma is shown to be formidable, but outside of battle she's a bit ditsy and easy to fool. An example of this was when Kinji fell on top of her after pulling her out of hole she dug and manage to be tricked into thinking it was training.
During middle school, Fuuma and Kinji had a practice spar where he was coincidentally in Hysteria Mode and had subdued her like a kid. Ever since then, she holds a huge respect to Kinji and calls him "Master" to his annoyance. Also due to being in poverty, Fuuma works part-time a lot, which she refers to as "training", in order to pay for her tuition as well as for subsistence.

- In Episode 10 of the main series, Fuuma makes a cameo appearance in the changing room scene.
