Kuron Nijino

Kuron Nijino (虹野黒音) is Cure Easel, one of the main characters of Hantai Precure. She is actually a fairy duo named Monoli and Irori, who transform into Cure Mono and Cure Color, respectively.

Appearance
Monili and Irori look very similar to one another, with long bushy tails and dog-like ears. True to their names, Monoli is black and white, while Irori is a multitude of colors.

Kuron has short black hair that she wears in a side ponytail. She has heterochromia, with one black eye and one orange eye. To cover this up, she usually wears sunglasses.

Etymology
Nijino (虹野): Niji (虹) means 'rainbow', referencing Cure Color. No (野) means "field" or "plain". As a syllabus, "no" also indicates a possessive. Her surname can also mean "of the rainbow".

Kuron (黒音): Kuro means 'black', referencing Cure Mono, and On means 'sound'. It is also a homophone for the English word 'clone', meaning a duplicate of someone, referencing how the Cures split into two beings when they transform.

Monoli and Irori, like all fairy pairs in the series, have one member with a "li" at the end of their name (representing 'left'), and the other with a 'ri' at the end of their name (representing 'right'). While Mono, like Cure Mono, comes from monocrome, Irori comes from iro, the Japanese word for color.
