Ні

is quite playful and vulgar with her words as she constantly insulted and made fun of her opponents. She is also quite a complainer as she constantly complains about Ichi's treatment of overworking her.She also had an overconfident mindset as she continuously underestimates the magical girls opponents that ambushed her and proclaimed that having her leg cut off wasn't a big deal, Ni has also shown to possess a psychotic wrathful side, viciously and violently lashing out at Rina Shioi for annoying her and later kills an innocent school guard for cutting/interfering with her angry rants,and later despite being cut into pieces still angrily screamed she would kill them all.

These violent personality traits may have come from her Host, Ochi Shizuka considering the trauma she had experienced.
