Noel Niihashi (新橋ニイハシ のえる, Nīhashi Noeru) is a Witch working for Wing Bind in Reverse London. She is the partner of Ninny Spangcole. Noel is a fairly stoic young woman who reacts to most situations with a mixture of seriousness and deadpan observations. She likes wearing uniforms, as they tell others who she is without her needing to do so herself, and prefers that others call her by her first name. However, she also has a somewhat sillier and less aloof side; she is fond of Balgo Parks's pet dog, Osushi, carrying treats to feed him with, and is very fond of Japanese culture, to the point of taking Noel as her first name because it is a girl's first name in Japan and having the narration theme from the Dragon Ball anime as her cell phone ringtone. Notably, even when displaying this softer side of hers, Noel remains calm and serious; the only two times she has ever lost her composure have both stemmed from Osushi (having absorbed negative emotions from Balgo and gaining the ability to speak the human language as a Dark Dragon) asking to see her panties, which resulted in her furiously screaming for Balgo to show himself the first time and pursuing Balgo and Osushi with murderous intent the second time. When not on the job and relaxing at her home, Noel is more cheerful and openly kind, taking joy in watering her Planty Potties and reading the daily newspaper; however, she does not like having to look after Balgo and cordons off his room with a curtain that he is not allowed to pass through without permission.
