Personality
She seems to be laid back, but sometimes shows a mean personality to others. She administers rulings for who is responsible for each floor under her. Despite her young appearance, she is calculated and is an experienced and knowledgeable arbiter.

Plot
I love Nona-sama very much. PLEASE!!!! LOVE ME!!!!

Decim
She takes her job as Decim's boss and also the job of an arbiter seriously, as she tells Decim after his realization of his judgment on Machiko and Takeshi that while it is alright to make mistakes, he should learn from this because humans are creatures who express themselves randomly and he should not dismiss them the next time he passes judgment. She is also annoyed when Decim fails Quin’s Memory Test because he couldn't tell one of the customers was a dummy and that the child customer (who was Ginti in disguise) should have had memories but he didn't receive them. However, she states that while she is annoyed with him and disappointed he failed the test, she still preferred him over Ginti.
