Nico resembles the sin of Greed. In modern Japan, her sin is 'The Eccentric Headcase' _(Japanese: 不思議メンヘラ, Romanized: Fushigi Menhera, Official English Translation: "Screw Loose")._ Her identification when she experiences pain is D-6. Nico appears to be bright and energetic, often being the comic relief of the series. She tends to overreact or be very dramatic when experiencing new things, and acts very feminine. However, Nico is shown to be rather perceptive in the series, much to her companions' surprise. Since she came from a wealthy family, it is implied that she has polite and lady-like manners.
