Author Naoko Takeuchi describes Chibiusa as a precocious brat who likes pulling pranks.She is the daughter of Neo-Queen Serenity and King Endymion. Her real name is the same as her mother's, but is called Chibiusa in Japanese (and Rini in English) to avoid confusion between the two. Her name in several English-languageversions of Sailor Moon, Rini, is a diminutive of "Serena", the name of her mother. She is known for having pink hair put into a unique style that resembles rabbit ears on top of her head. Chibiusa's hair is apparently truly pink, and not just colored that way for stylistic purposes; its color is stated in the manga's first Picture Diary and in the poem about her in the Sailor Stars CD single
